281-543 0e+00

Catalytic domain of the Protein Tyrosine Kinase, Abelson kinase; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Abl (or c-Abl) is a ubiquitously-expressed cytoplasmic (or nonreceptor) PTK that contains SH3, SH2, and tyr kinase domains in its N-terminal region, as well as nuclear localization motifs, a putative DNA-binding domain, and F- and G-actin binding domains in its C-terminal tail. It also contains a short autoinhibitory cap region in its N-terminus. Abl function depends on its subcellular localization. In the cytoplasm, Abl plays a role in cell proliferation and survival. In response to DNA damage or oxidative stress, Abl is transported to the nucleus where it induces apoptosis. In chronic myelogenous leukemia (CML) patients, an aberrant translocation results in the replacement of the first exon of Abl with the BCR (breakpoint cluster region) gene. The resulting BCR-Abl fusion protein is constitutively active and associates into tetramers, resulting in a hyperactive kinase sending a continuous signal. This leads to uncontrolled proliferation, morphological transformation and anti-apoptotic effects. BCR-Abl is the target of selective inhibitors, such as imatinib (Gleevec), used in the treatment of CML. Abl2, also known as ARG (Abelson-related gene), is thought to play a cooperative role with Abl in the proper development of the nervous system. The Tel-ARG fusion protein, resulting from reciprocal translocation between chromosomes 1 and 12, is associated with acute myeloid leukemia (AML). The TEL gene is a frequent fusion partner of other tyr kinase oncogenes, including Tel/Abl, Tel/PDGFRbeta, and Tel/Jak2, found in patients with leukemia and myeloproliferative disorders. The Abl subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

SH2_ABL cd09935
Src homology 2 (SH2) domain found in Abelson murine lymphosarcoma virus (ABL) proteins; ...
169-262 9.93e-61

Src homology 2 (SH2) domain found in Abelson murine lymphosarcoma virus (ABL) proteins; ABL-family proteins are highly conserved tyrosine kinases. Each ABL protein contains an SH3-SH2-TK (Src homology 3-Src homology 2-tyrosine kinase) domain cassette, which confers autoregulated kinase activity and is common among nonreceptor tyrosine kinases. Several types of posttranslational modifications control ABL catalytic activity, subcellular localization, and stability, with consequences for both cytoplasmic and nuclear ABL functions. Binding partners provide additional regulation of ABL catalytic activity, substrate specificity, and downstream signaling. By combining this cassette with actin-binding and -bundling domain, ABL proteins are capable of connecting phosphoregulation with actin-filament reorganization. Vertebrate paralogs, ABL1 and ABL2, have evolved to perform specialized functions. ABL1 includes nuclear localization signals and a DNA binding domain which is used to mediate DNA damage-repair functions, while ABL2 has additional binding capacity for actin and for microtubules to enhance its cytoskeletal remodeling functions. SH2 is involved in several autoinhibitory mechanism that constrain the enzymatic activity of the ABL-family kinases. In one mechanism SH2 and SH3 cradle the kinase domain while a cap sequence stabilizes the inactive conformation resulting in a locked inactive state. Another involves phosphatidylinositol 4,5-bisphosphate (PIP2) which binds the SH2 domain through residues normally required for phosphotyrosine binding in the linker segment between the SH2 and kinase domains. The SH2 domain contributes to ABL catalytic activity and target site specificity. It is thought that the ABL catalytic site and SH2 pocket have coevolved to recognize the same sequences. Recent work now supports a hierarchical processivity model in which the substrate target site most compatible with ABL kinase domain preferences is phosphorylated with greatest efficiency. If this site is compatible with the ABL SH2 domain specificity, it will then reposition and dock in the SH2 pocket. This mechanism also explains how ABL kinases phosphorylates poor targets on the same substrate if they are properly positioned and how relatively poor substrate proteins might be recruited to ABL through a complex with strong substrates that can also dock with the SH2 pocket. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.

288-539 8.45e-139

Protein tyrosine and serine/threonine kinase; Protein phosphorylation, which plays a key role in most cellular activities, is a reversible process mediated by protein kinases and phosphoprotein phosphatases. Protein kinases catalyze the transfer of the gamma phosphate from nucleotide triphosphates (often ATP) to one or more amino acid residues in a protein substrate side chain, resulting in a conformational change affecting protein function. Phosphoprotein phosphatases catalyze the reverse process. Protein kinases fall into three broad classes, characterized with respect to substrate specificity; Serine/threonine-protein kinases, tyrosine-protein kinases, and dual specificity protein kinases (e.g. MEK - phosphorylates both Thr and Tyr on target proteins). This entry represents the catalytic domain found in a number of serine/threonine- and tyrosine-protein kinases. It does not include the catalytic domain of dual specificity kinases.

Several types of posttranslational modifications control ABL catalytic activity, subcellular localization, and stability, with consequences for both cytoplasmic and nuclear ABL functions. Binding partners provide additional regulation of ABL catalytic activity, substrate specificity, and downstream signaling. By combining this cassette with actin-binding and -bundling domain, ABL proteins are capable of connecting phosphoregulation with actin-filament reorganization. Vertebrate paralogs, ABL1 and ABL2, have evolved to perform specialized functions. ABL1 includes nuclear localization signals and a DNA binding domain which is used to mediate DNA damage-repair functions, while ABL2 has additional binding capacity for actin and for microtubules to enhance its cytoskeletal remodeling functions. SH2 is involved in several autoinhibitory mechanism that constrain the enzymatic activity of the ABL-family kinases. In one mechanism SH2 and SH3 cradle the kinase domain while a cap sequence stabilizes the inactive conformation resulting in a locked inactive state. Another involves phosphatidylinositol 4,5-bisphosphate (PIP2) which binds the SH2 domain through residues normally required for phosphotyrosine binding in the linker segment between the SH2 and kinase domains. The SH2 domain contributes to ABL catalytic activity and target site specificity. It is thought that the ABL catalytic site and SH2 pocket have coevolved to recognize the same sequences. Recent work now supports a hierarchical processivity model in which the substrate target site most compatible with ABL kinase domain preferences is phosphorylated with greatest efficiency. If this site is compatible with the ABL SH2 domain specificity, it will then reposition and dock in the SH2 pocket. This mechanism also explains how ABL kinases phosphorylates poor targets on the same substrate if they are properly positioned and how relatively poor substrate proteins might be recruited to ABL through a complex with strong substrates that can also dock with the SH2 pocket. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

111-164 1.18e-27

Src homology 3 domain of the Protein Tyrosine Kinase, Abelson kinase; Abl (or c-Abl) is a ubiquitously-expressed cytoplasmic (or nonreceptor) PTK that contains SH3, SH2, and tyr kinase domains in its N-terminal region, as well as nuclear localization motifs, a putative DNA-binding domain, and F- and G-actin binding domains in its C-terminal tail. It also contains a short autoinhibitory cap region in its N-terminus. Abl function depends on its subcellular localization. In the cytoplasm, Abl plays a role in cell proliferation and survival. In response to DNA damage or oxidative stress, Abl is transported to the nucleus where it induces apoptosis. In chronic myelogenous leukemia (CML) patients, an aberrant translocation results in the replacement of the first exon of Abl with the BCR (breakpoint cluster region) gene. The resulting BCR-Abl fusion protein is constitutively active and associates into tetramers, resulting in a hyperactive kinase sending a continuous signal. This leads to uncontrolled proliferation, morphological transformation and anti-apoptotic effects. BCR-Abl is the target of selective inhibitors, such as imatinib (Gleevec), used in the treatment of CML. Abl2, also known as ARG (Abelson-related gene), is thought to play a cooperative role with Abl in the proper development of the nervous system. The Tel-ARG fusion protein, resulting from reciprocal translocation between chromosomes 1 and 12, is associated with acute myeloid leukemia (AML). SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.

Catalytic domain of the Protein Tyrosine Kinase, Abelson kinase; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Abl (or c-Abl) is a ubiquitously-expressed cytoplasmic (or nonreceptor) PTK that contains SH3, SH2, and tyr kinase domains in its N-terminal region, as well as nuclear localization motifs, a putative DNA-binding domain, and F- and G-actin binding domains in its C-terminal tail. It also contains a short autoinhibitory cap region in its N-terminus. Abl function depends on its subcellular localization. In the cytoplasm, Abl plays a role in cell proliferation and survival. In response to DNA damage or oxidative stress, Abl is transported to the nucleus where it induces apoptosis. In chronic myelogenous leukemia (CML) patients, an aberrant translocation results in the replacement of the first exon of Abl with the BCR (breakpoint cluster region) gene. The resulting BCR-Abl fusion protein is constitutively active and associates into tetramers, resulting in a hyperactive kinase sending a continuous signal. This leads to uncontrolled proliferation, morphological transformation and anti-apoptotic effects. BCR-Abl is the target of selective inhibitors, such as imatinib (Gleevec), used in the treatment of CML. Abl2, also known as ARG (Abelson-related gene), is thought to play a cooperative role with Abl in the proper development of the nervous system. The Tel-ARG fusion protein, resulting from reciprocal translocation between chromosomes 1 and 12, is associated with acute myeloid leukemia (AML). The TEL gene is a frequent fusion partner of other tyr kinase oncogenes, including Tel/Abl, Tel/PDGFRbeta, and Tel/Jak2, found in patients with leukemia and myeloproliferative disorders. The Abl subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

288-539 8.45e-139

Protein tyrosine and serine/threonine kinase; Protein phosphorylation, which plays a key role in most cellular activities, is a reversible process mediated by protein kinases and phosphoprotein phosphatases. Protein kinases catalyze the transfer of the gamma phosphate from nucleotide triphosphates (often ATP) to one or more amino acid residues in a protein substrate side chain, resulting in a conformational change affecting protein function. Phosphoprotein phosphatases catalyze the reverse process. Protein kinases fall into three broad classes, characterized with respect to substrate specificity; Serine/threonine-protein kinases, tyrosine-protein kinases, and dual specificity protein kinases (e.g. MEK - phosphorylates both Thr and Tyr on target proteins). This entry represents the catalytic domain found in a number of serine/threonine- and tyrosine-protein kinases. It does not include the catalytic domain of dual specificity kinases.

Catalytic domain of Protein Tyrosine Kinases; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. They can be classified into receptor and non-receptor tyr kinases. PTKs play important roles in many cellular processes including, lymphocyte activation, epithelium growth and maintenance, metabolism control, organogenesis regulation, survival, proliferation, differentiation, migration, adhesion, motility, and morphogenesis. Receptor tyr kinases (RTKs) are integral membrane proteins which contain an extracellular ligand-binding region, a transmembrane segment, and an intracellular tyr kinase domain. RTKs are usually activated through ligand binding, which causes dimerization and autophosphorylation of the intracellular tyr kinase catalytic domain, leading to intracellular signaling. Some RTKs are orphan receptors with no known ligands. Non-receptor (or cytoplasmic) tyr kinases are distributed in different intracellular compartments and are usually multi-domain proteins containing a catalytic tyr kinase domain as well as various regulatory domains such as SH3 and SH2. PTKs are usually autoinhibited and require a mechanism for activation. In many PTKs, the phosphorylation of tyr residues in the activation loop is essential for optimal activity. Aberrant expression of PTKs is associated with many development abnormalities and cancers.The PTK family is part of a larger superfamily that includes the catalytic domains of serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

293-540 3.09e-130

Catalytic domain of Src kinase-like Protein Tyrosine Kinases; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Src subfamily members include Src, Lck, Hck, Blk, Lyn, Fgr, Fyn, Yrk, and Yes. Src (or c-Src) proteins are cytoplasmic (or non-receptor) PTKs which are anchored to the plasma membrane. They contain an N-terminal SH4 domain with a myristoylation site, followed by SH3 and SH2 domains, a tyr kinase domain, and a regulatory C-terminal region containing a conserved tyr. They are activated by autophosphorylation at the tyr kinase domain, but are negatively regulated by phosphorylation at the C-terminal tyr by Csk (C-terminal Src Kinase). Src proteins are involved in signaling pathways that regulate cytokine and growth factor responses, cytoskeleton dynamics, cell proliferation, survival, and differentiation. They were identified as the first proto-oncogene products, and they regulate cell adhesion, invasion, and motility in cancer cells and tumor vasculature, contributing to cancer progression and metastasis. Src kinases are overexpressed in a variety of human cancers, making them attractive targets for therapy. They are also implicated in acute inflammatory responses and osteoclast function. Src, Fyn, Yes, and Yrk are widely expressed, while Blk, Lck, Hck, Fgr, and Lyn show a limited expression pattern. The Src-like subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

279-537 1.56e-123

Catalytic domain of Fyn-related kinase-like Protein Tyrosine Kinases; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Frk and Srk are members of the Src subfamily of proteins, which are cytoplasmic (or non-receptor) PTKs. Frk, also known as Rak, is specifically expressed in liver, lung, kidney, intestine, mammary glands, and the islets of Langerhans. Rodent homologs were previously referred to as GTK (gastrointestinal tyr kinase), BSK (beta-cell Src-like kinase), or IYK (intestinal tyr kinase). Studies in mice reveal that Frk is not essential for viability. It plays a role in the signaling that leads to cytokine-induced beta-cell death in Type I diabetes. It also regulates beta-cell number during embryogenesis and early in life. Src kinases contain an N-terminal SH4 domain with a myristoylation site, followed by SH3 and SH2 domains, a tyr kinase domain, and a regulatory C-terminal region containing a conserved tyr. They are activated by autophosphorylation at the tyr kinase domain, but are negatively regulated by phosphorylation at the C-terminal tyr by Csk (C-terminal Src Kinase). The Frk-like subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

281-541 1.30e-110

Catalytic domain of C-terminal Src kinase-like Protein Tyrosine Kinases; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. This subfamily is composed of Csk, Chk, and similar proteins. They are cytoplasmic (or nonreceptor) PTKs containing the Src homology domains, SH3 and SH2, N-terminal to the catalytic tyr kinase domain. They negatively regulate the activity of Src kinases that are anchored to the plasma membrane. To inhibit Src kinases, Csk and Chk are translocated to the membrane via binding to specific transmembrane proteins, G-proteins, or adaptor proteins near the membrane. Csk catalyzes the tyr phosphorylation of the regulatory C-terminal tail of Src kinases, resulting in their inactivation. Chk inhibit Src kinases using a noncatalytic mechanism by simply binding to them. As negative regulators of Src kinases, Csk and Chk play important roles in cell proliferation, survival, and differentiation, and consequently, in cancer development and progression. The Csk-like subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

287-534 1.55e-103

Catalytic domain of Tec-like Protein Tyrosine Kinases; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. The Tec-like subfamily is composed of Tec, Btk, Bmx (Etk), Itk (Tsk, Emt), Rlk (Txk), and similar proteins. They are cytoplasmic (or nonreceptor) PTKs with similarity to Src kinases in that they contain Src homology protein interaction domains (SH3, SH2) N-terminal to the catalytic tyr kinase domain. Unlike Src kinases, most Tec subfamily members except Rlk also contain an N-terminal pleckstrin homology (PH) domain, which binds the products of PI3K and allows membrane recruitment and activation. In addition, some members contain the Tec homology (TH) domain, which contains proline-rich and zinc-binding regions. Tec kinases form the second largest subfamily of nonreceptor PTKs and are expressed mainly by haematopoietic cells, although Tec and Bmx are also found in endothelial cells. B-cells express Btk and Tec, while T-cells express Itk, Txk, and Tec. Collectively, Tec kinases are expressed in a variety of myeloid cells such as mast cells, platelets, macrophages, and dendritic cells. Each Tec kinase shows a distinct cell-type pattern of expression. Tec kinases play important roles in the development, differentiation, maturation, regulation, survival, and function of B-cells and T-cells. Mutations in Btk cause the severe B-cell immunodeficiency, X-linked agammaglobulinaemia (XLA). The Tec-like subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

280-543 2.64e-99

Catalytic domain of the Protein Tyrosine Kinases, Lymphocyte-specific kinase and Blk; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Lck and Blk are members of the Src subfamily of proteins, which are cytoplasmic (or non-receptor) PTKs. Lck is expressed in T-cells and natural killer cells. It plays a critical role in T-cell maturation, activation, and T-cell receptor (TCR) signaling. Lck phosphorylates ITAM (immunoreceptor tyr activation motif) sequences on several subunits of TCRs, leading to the activation of different second messenger cascades. Phosphorylated ITAMs serve as binding sites for other signaling factor such as Syk and ZAP-70, leading to their activation and propagation of downstream events. In addition, Lck regulates drug-induced apoptosis by interfering with the mitochondrial death pathway. The apototic role of Lck is independent of its primary function in T-cell signaling. Blk is expressed specifically in B-cells. It is involved in pre-BCR (B-cell receptor) signaling. Src kinases contain an N-terminal SH4 domain with a myristoylation site, followed by SH3 and SH2 domains, a tyr kinase domain, and a regulatory C-terminal region containing a conserved tyr. They are activated by autophosphorylation at the tyr kinase domain, but are negatively regulated by phosphorylation at the C-terminal tyr by Csk (C-terminal Src Kinase). The Lck/Blk subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

281-537 6.25e-96

Catalytic domain of the Protein Tyrosine Kinases, Src-related kinase lacking C-terminal regulatory tyrosine and N-terminal myristylation sites (Srm) and Breast tumor kinase (Brk); PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Srm and Brk (also called protein tyrosine kinase 6) are members of the Src subfamily of proteins, which are cytoplasmic (or non-receptor) PTKs. Brk has been found to be overexpressed in a majority of breast tumors. Src kinases in general contain an N-terminal SH4 domain with a myristoylation site, followed by SH3 and SH2 domains, a tyr kinase domain, and a regulatory C-terminal region containing a conserved tyr; they are activated by autophosphorylation at the tyr kinase domain, but are negatively regulated by phosphorylation at the C-terminal tyr by Csk (C-terminal Src Kinase). Srm and Brk however, lack the N-terminal myristylation sites. Src proteins are involved in signaling pathways that regulate cytokine and growth factor responses, cytoskeleton dynamics, cell proliferation, survival, and differentiation. The Srm/Brk subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Protein Tyrosine Kinase, Lyn; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Lyn is a member of the Src subfamily of proteins, which are cytoplasmic (or non-receptor) PTKs. Lyn is expressed in B lymphocytes and myeloid cells. It exhibits both positive and negative regulatory roles in B cell receptor (BCR) signaling. Lyn, as well as Fyn and Blk, promotes B cell activation by phosphorylating ITAMs (immunoreceptor tyr activation motifs) in CD19 and in Ig components of BCR. It negatively regulates signaling by its unique ability to phosphorylate ITIMs (immunoreceptor tyr inhibition motifs) in cell surface receptors like CD22 and CD5. Lyn also plays an important role in G-CSF receptor signaling by phosphorylating a variety of adaptor molecules. Src kinases contain an N-terminal SH4 domain with a myristoylation site, followed by SH3 and SH2 domains, a tyr kinase domain, and a regulatory C-terminal region containing a conserved tyr. They are activated by autophosphorylation at the tyr kinase domain, but are negatively regulated by phosphorylation at the C-terminal tyr by Csk (C-terminal Src Kinase).

293-537 1.12e-95

Catalytic domain of Fes-like Protein Tyrosine Kinases; Protein Tyrosine Kinase (PTK) family; Fes subfamily; catalytic (c) domain. Fes subfamily members include Fes (or Fps), Fer, and similar proteins. The PTKc family is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, and phosphoinositide 3-kinase (PI3K). PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Fes subfamily proteins are cytoplasmic (or nonreceptor) tyr kinases containing an N-terminal region with FCH (Fes/Fer/CIP4 homology) and coiled-coil domains, followed by a SH2 domain, and a C-terminal catalytic domain. The genes for Fes (feline sarcoma) and Fps (Fujinami poultry sarcoma) were first isolated from tumor-causing retroviruses. The viral oncogenes encode chimeric Fes proteins consisting of Gag sequences at the N-termini, resulting in unregulated tyr kinase activity. Fes and Fer kinases play roles in haematopoiesis, inflammation and immunity, growth factor signaling, cytoskeletal regulation, cell migration and adhesion, and the regulation of cell-cell interactions. Fes and Fer show redundancy in their biological functions.

293-539 1.51e-93

Catalytic domain of a subset of Src kinase-like Protein Tyrosine Kinases; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. This subfamily includes a subset of Src-like PTKs including Src, Fyn, Yrk, and Yes, which are all widely expressed. Yrk has been detected only in chickens. It is primarily found in neuronal and epithelial cells and in macrophages. It may play a role in inflammation and in response to injury. Src (or c-Src) proteins are cytoplasmic (or non-receptor) PTKs which are anchored to the plasma membrane. They contain an N-terminal SH4 domain with a myristoylation site, followed by SH3 and SH2 domains, a tyr kinase domain, and a regulatory C-terminal region containing a conserved tyr. They are activated by autophosphorylation at the tyr kinase domain, but are negatively regulated by phosphorylation at the C-terminal tyr by Csk (C-terminal Src Kinase). Src proteins are involved in signaling pathways that regulate cytokine and growth factor responses, cytoskeleton dynamics, cell proliferation, survival, and differentiation. They were identified as the first proto-oncogene products, and they regulate cell adhesion, invasion, and motility in cancer cells and tumor vasculature, contributing to cancer progression and metastasis. They are also implicated in acute inflammatory responses and osteoclast function. The Src/Fyn-like subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of Spleen Tyrosine Kinase-like Protein Tyrosine Kinases; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. The Syk-like subfamily is composed of Syk, ZAP-70, Shark, and similar proteins. They are cytoplasmic (or nonreceptor) PTKs containing two Src homology 2 (SH2) domains N-terminal to the catalytic tyr kinase domain. They are involved in the signaling downstream of activated receptors (including B-cell, T-cell, and Fc receptors) that contain ITAMs (immunoreceptor tyr activation motifs), leading to processes such as cell proliferation, differentiation, survival, adhesion, migration, and phagocytosis. Syk is important in B-cell receptor signaling, while Zap-70 is primarily expressed in T-cells and NK cells, and is a crucial component in T-cell receptor signaling. Syk also plays a central role in Fc receptor-mediated phagocytosis in the adaptive immune system. Shark is exclusively expressed in ectodermally derived epithelia, and is localized preferentially to the apical surface of the epithelial cells, it may play a role in a signaling pathway for epithelial cell polarity. The Syk-like subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

276-542 2.54e-92

Catalytic domain of the Protein Tyrosine Kinases, Fibroblast Growth Factor Receptors; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. The FGFR subfamily consists of FGFR1, FGFR2, FGFR3, FGFR4, and similar proteins. They are receptor PTKs (RTKs) containing an extracellular ligand-binding region with three immunoglobulin-like domains, a transmembrane segment, and an intracellular catalytic domain. The binding of FGFRs to their ligands, the FGFs, and to heparin/heparan sulfate (HS) results in the formation of a ternary complex, which leads to receptor dimerization and activation, and intracellular signaling. There are at least 23 FGFs and four types of FGFRs. The binding of FGFs to FGFRs is promiscuous, in that a receptor may be activated by several ligands and a ligand may bind to more that one type of receptor. FGF/FGFR signaling is important in the regulation of embryonic development, homeostasis, and regenerative processes. Depending on the cell type and stage, FGFR signaling produces diverse cellular responses including proliferation, growth arrest, differentiation, and apoptosis. Aberrant signaling leads to many human diseases such as skeletal, olfactory, and metabolic disorders, as well as cancer. The FGFR subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase .

281-534 3.64e-88

Catalytic domain of the Protein Tyrosine Kinase, Focal Adhesion Kinase; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. FAK is a cytoplasmic (or nonreceptor) PTK that contains an autophosphorylation site and a FERM domain at the N-terminus, a central tyr kinase domain, proline-rich regions, and a C-terminal FAT (focal adhesion targeting) domain. FAK activity is dependent on integrin-mediated cell adhesion, which facilitates N-terminal autophosphorylation. Full activation is achieved by the phosphorylation of its two adjacent A-loop tyrosines. FAK is important in mediating signaling initiated at sites of cell adhesions and at growth factor receptors. Through diverse molecular interactions, FAK functions as a biosensor or integrator to control cell motility. It is a key regulator of cell survival, proliferation, migration and invasion, and thus plays an important role in the development and progression of cancer. Src binds to autophosphorylated FAK forming the FAK-Src dual kinase complex, which is activated in a wide variety of tumor cells and generates signals promoting growth and metastasis. FAK is being developed as a target for cancer therapy. The FAK subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Protein Tyrosine Kinase, Interleukin-2-inducible T-cell Kinase; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Itk, also known as Tsk or Emt, is a member of the Tec-like subfamily of proteins, which are cytoplasmic (or nonreceptor) PTKs with similarity to Src kinases in that they contain Src homology protein interaction domains (SH3, SH2) N-terminal to the catalytic tyr kinase domain. Unlike Src kinases, most Tec subfamily members except Rlk also contain an N-terminal pleckstrin homology (PH) domain, which binds the products of PI3K and allows membrane recruitment and activation. In addition, Itk contains the Tec homology (TH) domain containing one proline-rich region and a zinc-binding region. Itk is expressed in T-cells and mast cells, and is important in their development and differentiation. Of the three Tec kinases expressed in T-cells, Itk plays the predominant role in T-cell receptor (TCR) signaling. It is activated by phosphorylation upon TCR crosslinking and is involved in the pathway resulting in phospholipase C-gamma1 activation and actin polymerization. It also plays a role in the downstream signaling of the T-cell costimulatory receptor CD28, the T-cell surface receptor CD2, and the chemokine receptor CXCR4. In addition, Itk is crucial for the development of T-helper(Th)2 effector responses. The Itk subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

281-534 7.00e-87

Catalytic domain of Insulin Receptor-like Protein Tyrosine Kinases; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. The InsR subfamily is composed of InsR, Insulin-like Growth Factor-1 Receptor (IGF-1R), and similar proteins. InsR and IGF-1R are receptor PTKs (RTKs) composed of two alphabeta heterodimers. Binding of the ligand (insulin, IGF-1, or IGF-2) to the extracellular alpha subunit activates the intracellular tyr kinase domain of the transmembrane beta subunit. Receptor activation leads to autophosphorylation, stimulating downstream kinase activities, which initiate signaling cascades and biological function. InsR and IGF-1R, which share 84% sequence identity in their kinase domains, display physiologically distinct yet overlapping functions in cell growth, differentiation, and metabolism. InsR activation leads primarily to metabolic effects while IGF-1R activation stimulates mitogenic pathways. In cells expressing both receptors, InsR/IGF-1R hybrids are found together with classical receptors. Both receptors can interact with common adaptor molecules such as IRS-1 and IRS-2. The InsR-like subfamily is part of a larger superfamily that includes the catalytic domains of serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

279-540 8.37e-87

Catalytic domain of the Protein Tyrosine Kinase, Hematopoietic cell kinase; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Hck is a member of the Src subfamily of proteins, which are cytoplasmic (or non-receptor) PTKs. Hck is present in myeloid and lymphoid cells that play a role in the development of cancer. It may be important in the oncogenic signaling of the protein Tel-Abl, which induces a chronic myelogenous leukemia (CML)-like disease. Hck also acts as a negative regulator of G-CSF-induced proliferation of granulocytic precursors, suggesting a possible role in the development of acute myeloid leukemia (AML). In addition, Hck is essential in regulating the degranulation of polymorphonuclear leukocytes. Genetic polymorphisms affect the expression level of Hck, which affects PMN mediator release and influences the development of chronic obstructive pulmonary disease (COPD). Src kinases contain an N-terminal SH4 domain with a myristoylation site, followed by SH3 and SH2 domains, a tyr kinase domain, and a regulatory C-terminal region containing a conserved tyr. They are activated by autophosphorylation at the tyr kinase domain, but are negatively regulated by phosphorylation at the C-terminal tyr by Csk (C-terminal Src Kinase). The Hck subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Protein Tyrosine Kinase, C-terminal Src kinase; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Csk catalyzes the tyr phosphorylation of the regulatory C-terminal tail of Src kinases, resulting in their inactivation. Csk is expressed in a wide variety of tissues. As a negative regulator of Src, Csk plays a role in cell proliferation, survival, and differentiation, and consequently, in cancer development and progression. Csk is a cytoplasmic (or nonreceptor) PTK containing the Src homology domains, SH3 and SH2, N-terminal to the catalytic tyr kinase domain. To inhibit Src kinases, Csk is translocated to the membrane via binding to specific transmembrane proteins, G-proteins, or adaptor proteins near the membrane. In addition, Csk also shows Src-independent functions. It is a critical component in G-protein signaling, and plays a role in cytoskeletal reorganization and cell migration. The Csk subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

283-534 3.23e-85

Catalytic domain of the Protein Tyrosine Kinases, Bruton's tyrosine kinase and Bone marrow kinase on the X chromosome; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Btk and Bmx (also named Etk) are members of the Tec-like subfamily of proteins, which are cytoplasmic (or nonreceptor) PTKs with similarity to Src kinases in that they contain Src homology protein interaction domains (SH3, SH2) N-terminal to the catalytic tyr kinase domain. Unlike Src kinases, most Tec subfamily members except Rlk also contain an N-terminal pleckstrin homology (PH) domain, which binds the products of PI3K and allows membrane recruitment and activation. In addition, Btk contains the Tec homology (TH) domain with proline-rich and zinc-binding regions. Btk is expressed in B-cells, and a variety of myeloid cells including mast cells, platelets, neutrophils, and dendrictic cells. It interacts with a variety of partners, from cytosolic proteins to nuclear transcription factors, suggesting a diversity of functions. Stimulation of a diverse array of cell surface receptors, including antigen engagement of the B-cell receptor, leads to PH-mediated membrane translocation of Btk and subsequent phosphorylation by Src kinase and activation. Btk plays an important role in the life cycle of B-cells including their development, differentiation, proliferation, survival, and apoptosis. Mutations in Btk cause the primary immunodeficiency disease, X-linked agammaglobulinaemia (XLA) in humans. Bmx is primarily expressed in bone marrow and the arterial endothelium, and plays an important role in ischemia-induced angiogenesis. It facilitates arterial growth, capillary formation, vessel maturation, and bone marrow-derived endothelial progenitor cell mobilization. The Btk/Bmx subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

286-542 3.10e-84

Catalytic domain of Ephrin Receptor Protein Tyrosine Kinases; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. EphRs comprise the largest subfamily of receptor PTKs (RTKs). They can be classified into two classes (EphA and EphB), according to their extracellular sequences, which largely correspond to binding preferences for either GPI-anchored ephrin-A ligands or transmembrane ephrin-B ligands. Vertebrates have ten EphA and six EphB receptors, which display promiscuous ligand interactions within each class. EphRs contain an ephrin binding domain and two fibronectin repeats extracellularly, a transmembrane segment, and a cytoplasmic tyr kinase domain. Binding of the ephrin ligand to EphR requires cell-cell contact since both are anchored to the plasma membrane. This allows ephrin/EphR dimers to form, leading to the activation of the intracellular tyr kinase domain. The resulting downstream signals occur bidirectionally in both EphR-expressing cells (forward signaling) and ephrin-expressing cells (reverse signaling). The main effect of ephrin/EphR interaction is cell-cell repulsion or adhesion. Ephrin/EphR signaling is important in neural development and plasticity, cell morphogenesis and proliferation, cell-fate determination, embryonic development, tissue patterning, and angiogenesis.The EphR subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

279-543 3.56e-84

Catalytic domain of the Protein Tyrosine Kinase, Yes; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Yes (or c-Yes) is a member of the Src subfamily of proteins, which are cytoplasmic (or non-receptor) PTKs. c-Yes kinase is the cellular homolog of the oncogenic protein (v-Yes) encoded by the Yamaguchi 73 and Esh sarcoma viruses. It displays functional overlap with other Src subfamily members, particularly Src. It also shows some unique functions such as binding to occludins, transmembrane proteins that regulate extracellular interactions in tight junctions. Yes also associates with a number of proteins in different cell types that Src does not interact with, like JAK2 and gp130 in pre-adipocytes, and Pyk2 in treated pulmonary vein endothelial cells. Although the biological function of Yes remains unclear, it appears to have a role in regulating cell-cell interactions and vesicle trafficking in polarized cells. Src kinases contain an N-terminal SH4 domain with a myristoylation site, followed by SH3 and SH2 domains, a tyr kinase domain, and a regulatory C-terminal region containing a conserved tyr. They are activated by autophosphorylation at the tyr kinase domain, but are negatively regulated by phosphorylation at the C-terminal tyr by Csk (C-terminal Src Kinase). The Yes subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase (PI3K).

Catalytic domain of the Protein Tyrosine Kinases, Discoidin Domain Receptors; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. The DDR subfamily consists of homologs of mammalian DDR1, DDR2, and similar proteins. They are receptor PTKs (RTKs) containing an extracellular discoidin homology domain, a transmembrane segment, an extended juxtamembrane region, and an intracellular catalytic domain. The binding of the ligand, collagen, to DDRs results in a slow but sustained receptor activation. DDRs regulate cell adhesion, proliferation, and extracellular matrix remodeling. They have been linked to a variety of human cancers including breast, colon, ovarian, brain, and lung. There is no evidence showing that DDRs act as transforming oncogenes. They are more likely to play a role in the regulation of tumor growth and metastasis. The DDR subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Protein Tyrosine Kinase, Fer; Protein Tyrosine Kinase (PTK) family; Fer kinase; catalytic (c) domain. The PTKc family is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, and phosphoinositide 3-kinase (PI3K). PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Fer kinase is a member of the Fes subfamily of proteins which are cytoplasmic (or nonreceptor) tyr kinases containing an N-terminal region with FCH (Fes/Fer/CIP4 homology) and coiled-coil domains, followed by a SH2 domain, and a C-terminal catalytic domain. Fer kinase is expressed in a wide variety of tissues, and is found to reside in both the cytoplasm and the nucleus. It plays important roles in neuronal polarization and neurite development, cytoskeletal reorganization, cell migration, growth factor signaling, and the regulation of cell-cell interactions mediated by adherens junctions and focal adhesions. Fer kinase also regulates cell cycle progression in malignant cells.

286-534 6.24e-83

Catalytic domain of the Protein Tyrosine Kinases, Tyrosine kinase expressed in hepatocellular carcinoma and Resting lymphocyte kinase; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Tec and Rlk (also named Txk) are members of the Tec-like subfamily of proteins, which are cytoplasmic (or nonreceptor) PTKs with similarity to Src kinases in that they contain Src homology protein interaction domains (SH3, SH2) N-terminal to the catalytic tyr kinase domain. Unlike Src kinases, most Tec subfamily members except Rlk also contain an N-terminal pleckstrin homology (PH) domain, which binds the products of PI3K and allows membrane recruitment and activation. Instead of PH, Rlk contains an N-terminal cysteine-rich region. In addition to PH, Tec also contains the Tec homology (TH) domain with proline-rich and zinc-binding regions. Tec kinases are expressed mainly by haematopoietic cells. Tec is more widely-expressed than other Tec-like subfamily kinases. It is found in endothelial cells, both B- and T-cells, and a variety of myeloid cells including mast cells, erythroid cells, platelets, macrophages and neutrophils. Rlk is expressed in T-cells and mast cell lines. Tec and Rlk are both key components of T-cell receptor (TCR) signaling. They are important in TCR-stimulated proliferation, IL-2 production and phopholipase C-gamma1 activation. The Tec/Rlk subfamily is part of a larger superfamily, that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-545 2.84e-82

Catalytic domain of Epidermal Growth Factor Receptor-like Protein Tyrosine Kinases; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. EGFR (HER, ErbB) subfamily members include EGFR (HER1, ErbB1), HER2 (ErbB2), HER3 (ErbB3), HER4 (ErbB4), and similar proteins. They are receptor PTKs (RTKs) containing an extracellular EGF-related ligand-binding region, a transmembrane helix, and a cytoplasmic region with a tyr kinase domain and a regulatory C-terminal tail. Unlike other PTKs, phosphorylation of the activation loop of EGFR proteins is not critical to their activation. Instead, they are activated by ligand-induced dimerization, resulting in the phosphorylation of tyr residues in the C-terminal tail, which serve as binding sites for downstream signaling molecules. Collectively, they can recognize a variety of ligands including EGF, TGFalpha, and neuregulins, among others. All four subfamily members can form homo- or heterodimers. HER3 contains an impaired kinase domain and depends on its heterodimerization partner for activation. EGFR subfamily members are involved in signaling pathways leading to a broad range of cellular responses including cell proliferation, differentiation, migration, growth inhibition, and apoptosis. Gain of function alterations, through their overexpression, deletions, or point mutations in their kinase domains, have been implicated in various cancers. These receptors are targets of many small molecule inhibitors and monoclonal antibodies used in cancer therapy. The EGFR subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

279-543 5.65e-82

Catalytic domain of the Protein Tyrosine Kinase, Fyn; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Fyn and Yrk are members of the Src subfamily of proteins, which are cytoplasmic (or non-receptor) PTKs. Fyn, together with Lck, plays a critical role in T-cell signal transduction by phosphorylating ITAM (immunoreceptor tyr activation motif) sequences on T-cell receptors, ultimately leading to the proliferation and differentiation of T-cells. In addition, Fyn is involved in the myelination of neurons, and is implicated in Alzheimer's and Parkinson's diseases. Src kinases contain an N-terminal SH4 domain with a myristoylation site, followed by SH3 and SH2 domains, a tyr kinase domain, and a regulatory C-terminal region containing a conserved tyr. They are activated by autophosphorylation at the tyr kinase domain, but are negatively regulated by phosphorylation at the C-terminal tyr by Csk (C-terminal Src Kinase). The Fyn/Yrk subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as serine/threonine kinases, RIO kinases, and phosphoinositide 3-kinase.

279-539 1.11e-81

Catalytic domain of the Protein Tyrosine Kinase, Src; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Src (or c-Src) is a cytoplasmic (or non-receptor) PTK, containing an N-terminal SH4 domain with a myristoylation site, followed by SH3 and SH2 domains, a tyr kinase domain, and a regulatory C-terminal region with a conserved tyr. It is activated by autophosphorylation at the tyr kinase domain, and is negatively regulated by phosphorylation at the C-terminal tyr by Csk (C-terminal Src Kinase). c-Src is the vertebrate homolog of the oncogenic protein (v-Src) from Rous sarcoma virus. Together with other Src subfamily proteins, it is involved in signaling pathways that regulate cytokine and growth factor responses, cytoskeleton dynamics, cell proliferation, survival, and differentiation. Src also play a role in regulating cell adhesion, invasion, and motility in cancer cells and tumor vasculature, contributing to cancer progression and metastasis. Elevated levels of Src kinase activity have been reported in a variety of human cancers. Several inhibitors of Src have been developed as anti-cancer drugs. Src is also implicated in acute inflammatory responses and osteoclast function. The Src subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-534 2.20e-81

Catalytic domain of Mitogen-Activated Protein Kinase (MAPK) Kinase Kinase-like Serine/Threonine kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. This subfamily is composed mainly of MAP3Ks and similar proteins, including TGF-beta Activated Kinase-1 (TAK1, also called MAP3K7), MAP3K12, MAP3K13, Mixed lineage kinase (MLK), MLK-Like mitogen-activated protein Triple Kinase (MLTK), and Raf (Rapidly Accelerated Fibrosarcoma) kinases. MAP3Ks (MKKKs or MAPKKKs) phosphorylate and activate MAPK kinases (MAPKKs or MKKs or MAP2Ks), which in turn phosphorylate and activate MAPKs during signaling cascades that are important in mediating cellular responses to extracellular signals. Also included in this subfamily is the pseudokinase Kinase Suppressor of Ras (KSR), which is a scaffold protein that functions downstream of Ras and upstream of Raf in the Extracellular signal-Regulated Kinase (ERK) pathway.

294-540 3.24e-80

Catalytic Domain of TAM (Tyro3, Axl, Mer) Protein Tyrosine Kinases; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. The TAM subfamily consists of Tyro3 (or Sky), Axl, Mer (or Mertk), and similar proteins. TAM subfamily members are receptor tyr kinases (RTKs) containing an extracellular ligand-binding region with two immunoglobulin-like domains followed by two fibronectin type III repeats, a transmembrane segment, and an intracellular catalytic domain. Binding to their ligands, Gas6 and protein S, leads to receptor dimerization, autophosphorylation, activation, and intracellular signaling. TAM proteins are implicated in a variety of cellular effects including survival, proliferation, migration, and phagocytosis. They are also associated with several types of cancer as well as inflammatory, autoimmune, vascular, and kidney diseases. The TAM subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

281-542 8.25e-79

Catalytic domain of the Protein Tyrosine Kinase, Csk homologous kinase; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Chk is also referred to as megakaryocyte-associated tyrosine kinase (Matk). Chk inhibits Src kinases using a noncatalytic mechanism by simply binding to them. As a negative regulator of Src kinases, Chk may play important roles in cell proliferation, survival, and differentiation, and consequently, in cancer development and progression. Chk is expressed in brain and hematopoietic cells. Like Csk, it is a cytoplasmic (or nonreceptor) tyr kinase containing the Src homology domains, SH3 and SH2, N-terminal to the catalytic tyr kinase domain. To inhibit Src kinases that are anchored to the plasma membrane, Chk is translocated to the membrane via binding to specific transmembrane proteins, G-proteins, or adaptor proteins near the membrane. Studies in mice reveal that Chk is not functionally redundant with Csk and that it plays an important role as a regulator of immune responses. Chk also plays a role in neural differentiation in a manner independent of Src by enhancing Mapk activation via Ras-mediated signaling. The Chk subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Protein Tyrosine Kinase, Activated Cdc42-associated kinase; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. This subfamily includes Ack1, thirty-eight-negative kinase 1 (Tnk1), and similar proteins. They are cytoplasmic (or nonreceptor) PTKs containing an N-terminal catalytic domain, an SH3 domain, a Cdc42-binding CRIB domain, and a proline-rich region. They are mainly expressed in brain and skeletal tissues and are involved in the regulation of cell adhesion and growth, receptor degradation, and axonal guidance. Ack1 is also associated with androgen-independent prostate cancer progression. Tnk1 regulates TNFalpha signaling and may play an important role in cell death. The Ack-like subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-533 1.52e-78

Catalytic domain of the Protein Tyrosine Kinase, C-ros; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. This subfamily contains c-ros, Sevenless, and similar proteins. The proto-oncogene c-ros encodes an orphan receptor PTK (RTK) with an unknown ligand. RTKs contain an extracellular ligand-binding domain, a transmembrane region, and an intracellular tyr kinase domain. RTKs are usually activated through ligand binding, which causes dimerization and autophosphorylation of the intracellular tyr kinase catalytic domain. C-ros is expressed in embryonic cells of the kidney, intestine and lung, but disappears soon after birth. It persists only in the adult epididymis. Male mice bearing inactive mutations of c-ros lack the initial segment of the epididymis and are infertile. The Drosophila protein, Sevenless, is required for the specification of the R7 photoreceptor cell during eye development. The c-ros subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

292-537 4.68e-78

Catalytic Domain of the Protein Tyrosine Kinases, Receptor tyrosine kinase-like Orphan Receptors; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. The Ror subfamily consists of Ror1, Ror2, and similar proteins. Ror proteins are orphan receptor PTKs (RTKs) containing an extracellular region with immunoglobulin-like, cysteine-rich, and kringle domains, a transmembrane segment, and an intracellular catalytic domain. Ror RTKs are unrelated to the nuclear receptor subfamily called retinoid-related orphan receptors (RORs). RTKs are usually activated through ligand binding, which causes dimerization and autophosphorylation of the intracellular tyr kinase catalytic domain. Ror kinases are expressed in many tissues during development. They play important roles in bone and heart formation. Mutations in human Ror2 result in two different bone development genetic disorders, recessive Robinow syndrome and brachydactyly type B. Drosophila Ror is expressed only in the developing nervous system during neurite outgrowth and neuronal differentiation, suggesting a role for Drosophila Ror in neural development. More recently, mouse Ror1 and Ror2 have also been found to play an important role in regulating neurite growth in central neurons. Ror1 and Ror2 are believed to have some overlapping and redundant functions. The Ror subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Protein Tyrosine Kinases, Platelet Derived Growth Factor Receptors; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. The PDGFR subfamily consists of PDGFR alpha, PDGFR beta, KIT, CSF-1R, the mammalian FLT3, and similar proteins. They are receptor PTKs (RTKs) containing an extracellular ligand-binding region with five immunoglobulin-like domains, a transmembrane segment, and an intracellular catalytic domain. PDGFR kinase domains are autoinhibited by their juxtamembrane regions containing tyr residues. The binding to their ligands leads to receptor dimerization, trans phosphorylation and activation, and intracellular signaling. PDGFR subfamily receptors are important in the development of a variety of cells. PDGFRs are expressed in a many cells including fibroblasts, neurons, endometrial cells, mammary epithelial cells, and vascular smooth muscle cells. PDGFR signaling is critical in normal embryonic development, angiogenesis, and wound healing. Kit is important in the development of melanocytes, germ cells, mast cells, hematopoietic stem cells, the interstitial cells of Cajal, and the pacemaker cells of the GI tract. CSF-1R signaling is critical in the regulation of macrophages and osteoclasts. Mammalian FLT3 plays an important role in the survival, proliferation, and differentiation of stem cells. The PDGFR subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase .

Catalytic domain of the Protein Tyrosine Kinase, Muscle-specific kinase; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Musk is a receptor PTK (RTK) containing an extracellular region with four immunoglobulin-like domains and a cysteine-rich cluster, a transmembrane segment, and an intracellular catalytic domain. Musk is expressed and concentrated in the postsynaptic membrane in skeletal muscle. It is essential for the establishment of the neuromuscular junction (NMJ), a peripheral synapse that conveys signals from motor neurons to muscle cells. Agrin, a large proteoglycan released from motor neurons, stimulates Musk autophosphorylation and activation, leading to the clustering of acetylcholine receptors (AChRs). To date, there is no evidence to suggest that agrin binds directly to Musk. Mutations in AChR, Musk and other partners are responsible for diseases of the NMJ, such as the autoimmune syndrome myasthenia gravis. The Musk subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Protein Tyrosine Kinase, Fes; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Fes (or Fps) is a cytoplasmic (or nonreceptor) PTK containing an N-terminal region with FCH (Fes/Fer/CIP4 homology) and coiled-coil domains, followed by a SH2 domain, and a C-terminal catalytic domain. The genes for Fes (feline sarcoma) and Fps (Fujinami poultry sarcoma) were first isolated from tumor-causing retroviruses. The viral oncogenes encode chimeric Fes proteins consisting of Gag sequences at the N-termini, resulting in unregulated PTK activity. Fes kinase is expressed in myeloid, vascular endothelial, epithelial, and neuronal cells. It plays important roles in cell growth and differentiation, angiogenesis, inflammation and immunity, and cytoskeletal regulation. A recent study implicates Fes kinase as a tumor suppressor in colorectal cancer. The Fes subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic Domain of the Protein Tyrosine Kinase, Mer; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Mer (or Mertk) is named after its original reported expression pattern (monocytes, epithelial, and reproductive tissues). It is required for the ingestion of apoptotic cells by phagocytes such as macrophages, retinal pigment epithelial cells, and dendritic cells. Mer is also important in maintaining immune homeostasis. Mer is a member of the TAM subfamily, composed of receptor PTKs (RTKs) containing an extracellular ligand-binding region with two immunoglobulin-like domains followed by two fibronectin type III repeats, a transmembrane segment, and an intracellular catalytic domain. Binding to their ligands, Gas6 and protein S, leads to receptor dimerization, autophosphorylation, activation, and intracellular signaling. The Mer subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Protein Tyrosine Kinases, Anaplastic Lymphoma Kinase and Leukocyte Tyrosine Kinase; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyr residues in protein substrates. ALK and LTK are orphan receptor PTKs (RTKs) whose ligands are not yet well-defined. ALK appears to play an important role in mammalian neural development as well as visceral muscle differentiation in Drosophila. ALK is aberrantly expressed as fusion proteins, due to chromosomal translocations, in about 60% of anaplastic large cell lymphomas (ALCLs). ALK fusion proteins are also found in rare cases of diffuse large B cell lymphomas (DLBCLs). LTK is mainly expressed in B lymphocytes and neuronal tissues. It is important in cell proliferation and survival. Transgenic mice expressing TLK display retarded growth and high mortality rate. In addition, a polymorphism in mouse and human LTK is implicated in the pathogenesis of systemic lupus erythematosus. RTKs contain an extracellular ligand-binding domain, a transmembrane region, and an intracellular tyr kinase domain. They are usually activated through ligand binding, which causes dimerization and autophosphorylation of the intracellular tyr kinase catalytic domain. The ALK/LTK subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

276-551 5.06e-75

Catalytic domain of the Protein Tyrosine Kinase, Fibroblast Growth Factor Receptor 4; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Unlike other FGFRs, there is only one splice form of FGFR4. It binds FGF1, FGF2, FGF6, FGF19, and FGF23. FGF19 is a selective ligand for FGFR4. Although disruption of FGFR4 in mice causes no obvious phenotype, in vivo inhibition of FGFR4 in cultured skeletal muscle cells resulted in an arrest of muscle progenitor differentiation. FGF6 and FGFR4 are uniquely expressed in myofibers and satellite cells. FGF6/FGFR4 signaling appears to play a key role in the regulation of muscle regeneration. A polymorphism in FGFR4 is found in head and neck squamous cell carcinoma. FGFR4 is part of the FGFR subfamily, which are receptor PTKs (RTKs) containing an extracellular ligand-binding region with three immunoglobulin-like domains, a transmembrane segment, and an intracellular catalytic domain. The binding of FGFRs to their ligands, the FGFs, results in receptor dimerization and activation, and intracellular signaling. The binding of FGFs to FGFRs is promiscuous, in that a receptor may be activated by several ligands and a ligand may bind to more that one type of receptor. The FGFR4 subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

288-545 9.69e-75

Catalytic domain of the Protein Tyrosine Kinase, Axl; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Axl is widely expressed in a variety of organs and cells including epithelial, mesenchymal, hematopoietic, as well as non-transformed cells. It is important in many cellular functions such as survival, anti-apoptosis, proliferation, migration, and adhesion. Axl was originally isolated from patients with chronic myelogenous leukemia and a chronic myeloproliferative disorder. It is overexpressed in many human cancers including colon, squamous cell, thyroid, breast, and lung carcinomas. Axl is a member of the TAM subfamily, composed of receptor PTKs (RTKs) containing an extracellular ligand-binding region with two immunoglobulin-like domains followed by two fibronectin type III repeats, a transmembrane segment, and an intracellular catalytic domain. Binding to its ligands, Gas6 and protein S, leads to receptor dimerization, autophosphorylation, activation, and intracellular signaling. The Axl subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Protein Tyrosine Kinases, Tropomyosin Related Kinases; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. The Trk subfamily consists of TrkA, TrkB, TrkC, and similar proteins. They are receptor PTKs (RTKs) containing an extracellular region with arrays of leucine-rich motifs flanked by two cysteine-rich clusters followed by two immunoglobulin-like domains, a transmembrane segment, and an intracellular catalytic domain. Binding to their ligands, the nerve growth factor (NGF) family of neutrotrophins, leads to Trk receptor oligomerization and activation of the catalytic domain. Trk receptors are mainly expressed in the peripheral and central nervous systems. They play important roles in cell fate determination, neuronal survival and differentiation, as well as in the regulation of synaptic plasticity. Altered expression of Trk receptors is associated with many human diseases. The Trk subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-542 2.20e-72

Catalytic domain of the Protein Tyrosine Kinase, REarranged during Transfection protein; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. RET is a receptor PTK (RTK) containing an extracellular region with four cadherin-like repeats, a calcium-binding site, and a cysteine-rich domain, a transmembrane segment, and an intracellular catalytic domain. It is part of a multisubunit complex that binds glial-derived neurotropic factor (GDNF) family ligands (GFLs) including GDNF, neurturin, artemin, and persephin. GFLs bind RET along with four GPI-anchored coreceptors, bringing two RET molecules together, leading to autophosphorylation, activation, and intracellular signaling. RET is essential for the development of the sympathetic, parasympathetic and enteric nervous systems, and the kidney. RET disruption by germline mutations causes diseases in humans including congenital aganglionosis of the gastrointestinal tract (Hirschsprung's disease) and three related inherited cancers: multiple endocrine neoplasia type 2A (MEN2A), MEN2B, and familial medullary thyroid carcinoma. The RET subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-543 8.54e-71

Catalytic domain of the Protein Tyrosine Kinases, Met and Ron; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Met and Ron are receptor PTKs (RTKs) composed of an alpha-beta heterodimer. The extracellular alpha chain is disulfide linked to the beta chain, which contains an extracellular ligand-binding region with a sema domain, a PSI domain and four IPT repeats, a transmembrane segment, and an intracellular catalytic domain. Binding to their ligands leads to receptor dimerization, autophosphorylation, activation, and intracellular signaling. Met binds to the ligand, hepatocyte growth factor/scatter factor (HGF/SF), and is also called the HGF receptor. HGF/Met signaling plays a role in growth, transformation, cell motility, invasion, metastasis, angiogenesis, wound healing, and tissue regeneration. Aberrant expression of Met through mutations or gene amplification is associated with many human cancers including hereditary papillary renal and gastric carcinomas. The ligand for Ron is macrophage stimulating protein (MSP). Ron signaling is important in regulating cell motility, adhesion, proliferation, and apoptosis. Aberrant Ron expression is implicated in tumorigenesis and metastasis. The Met/Ron subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

293-533 1.47e-70

Catalytic domain of the Protein Tyrosine Kinase, Spleen tyrosine kinase; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Syk is a cytoplasmic (or nonreceptor) PTK containing two Src homology 2 (SH2) domains N-terminal to the catalytic tyr kinase domain. Syk was first cloned from the spleen, and its function in hematopoietic cells is well-established. It is involved in the signaling downstream of activated receptors (including B-cell and Fc receptors) that contain ITAMs (immunoreceptor tyr activation motifs), leading to processes such as cell proliferation, differentiation, survival, adhesion, migration, and phagocytosis. More recently, Syk expression has been detected in other cell types (including epithelial cells, vascular endothelial cells, neurons, hepatocytes, and melanocytes), suggesting a variety of biological functions in non-immune cells. Syk plays a critical role in maintaining vascular integrity and in wound healing during embryogenesis. It also regulates Vav3, which is important in osteoclast function including bone development. In breast epithelial cells, where Syk acts as a negative regulator for EGFR signaling, loss of Syk expression is associated with abnormal proliferation during cancer development suggesting a potential role as a tumor suppressor. In mice, Syk has been shown to inhibit malignant transformation of mammary epithelial cells induced with murine mammary tumor virus (MMTV). The Syk subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Protein Tyrosine Kinase, Epidermal Growth Factor Receptor; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. EGFR (HER1, ErbB1) is a receptor PTK (RTK) containing an extracellular EGF-related ligand-binding region, a transmembrane helix, and a cytoplasmic region with a tyr kinase domain and a regulatory C-terminal tail. Unlike other PTKs, phosphorylation of the activation loop of EGFR proteins is not critical to their activation. Instead, they are activated by ligand-induced dimerization, leading to the phosphorylation of tyr residues in the C-terminal tail, which serve as binding sites for downstream signaling molecules. Ligands for EGFR include EGF, heparin binding EGF-like growth factor (HBEGF), epiregulin, amphiregulin, TGFalpha, and betacellulin. Upon ligand binding, EGFR can form homo- or heterodimers with other EGFR subfamily members. The EGFR signaling pathway is one of the most important pathways regulating cell proliferation, differentiation, survival, and growth. Overexpression and mutation in the kinase domain of EGFR have been implicated in the development and progression of a variety of cancers. A number of monoclonal antibodies and small molecule inhibitors have been developed that target EGFR, including the antibodies Cetuximab and Panitumumab, which are used in combination with other therapies for the treatment of colorectal cancer and non-small cell lung carcinoma (NSCLC). The small molecule inhibitors Gefitinib (Iressa) and Erlotinib (Tarceva), already used for NSCLC, are undergoing clinical trials for other types of cancer including gastrointestinal, breast, head and neck, and bladder. The EGFR subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

293-534 6.64e-70

Catalytic (repeat 2) domain of the Protein Tyrosine Kinases, Janus kinases; The Jak subfamily is composed of Jak1, Jak2, Jak3, TYK2, and similar proteins. They are PTKs, catalyzing the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Jaks are cytoplasmic (or nonreceptor) PTKs containing an N-terminal FERM domain, followed by a Src homology 2 (SH2) domain, a pseudokinase domain, and a C-terminal tyr kinase catalytic domain. Most Jaks are expressed in a wide variety of tissues, except for Jak3, which is expressed only in hematopoietic cells. Jaks are crucial for cytokine receptor signaling. They are activated by autophosphorylation upon cytokine-induced receptor aggregation, and subsequently trigger downstream signaling events such as the phosphorylation of signal transducers and activators of transcription (STATs). Jaks are also involved in regulating the surface expression of some cytokine receptors. The Jak-STAT pathway is involved in many biological processes including hematopoiesis, immunoregulation, host defense, fertility, lactation, growth, and embryogenesis. The Jak subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

282-534 1.46e-69

Catalytic domain of the Protein Tyrosine Kinase, Ephrin Receptor A2; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. The EphA2 receptor is overexpressed in tumor cells and tumor blood vessels in a variety of cancers including breast, prostate, lung, and colon. As a result, it is an attractive target for drug design since its inhibition could affect several aspects of tumor progression. EphRs comprise the largest subfamily of receptor PTKs (RTKs). Class EphA receptors bind GPI-anchored ephrin-A ligands. There are ten vertebrate EphA receptors (EphA1-10), which display promiscuous interactions with six ephrin-A ligands. EphRs contain an ephrin binding domain and two fibronectin repeats extracellularly, a transmembrane segment, and a cytoplasmic tyr kinase domain. Binding of the ephrin ligand to EphR requires cell-cell contact since both are anchored to the plasma membrane. The resulting downstream signals occur bidirectionally in both EphR-expressing cells (forward signaling) and ephrin-expressing cells (reverse signaling). Ephrin/EphR interaction mainly results in cell-cell repulsion or adhesion, making it important in neural development and plasticity, cell morphogenesis, cell-fate determination, embryonic development, tissue patterning, and angiogenesis. The EphA2 subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, and phosphoinositide 3-kinase (PI3K).

Catalytic domain of the Protein Tyrosine Kinase, Fibroblast Growth Factor Receptor 2; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. There are many splice variants of FGFR2 which show differential expression and binding to FGF ligands. Disruption of either FGFR2 or FGFR2b is lethal in mice, due to defects in the placenta or severe impairment of tissue development including lung, limb, and thyroid, respectively. Disruption of FGFR2c in mice results in defective bone and skull development. Genetic alterations of FGFR2 are associated with many human skeletal disorders including Apert syndrome, Crouzon syndrome, Jackson-Weiss syndrome, and Pfeiffer syndrome. FGFR2 is part of the FGFR subfamily, which are receptor PTKs (RTKs) containing an extracellular ligand-binding region with three immunoglobulin-like domains, a transmembrane segment, and an intracellular catalytic domain. The binding of FGFRs to their ligands, the FGFs, results in receptor dimerization and activation, and intracellular signaling. The binding of FGFs to FGFRs is promiscuous, in that a receptor may be activated by several ligands and a ligand may bind to more that one type of receptor. The FGFR2 subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

283-547 1.62e-68

Catalytic domain of the Protein Tyrosine Kinase, HER2; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. HER2 (ErbB2, HER2/neu) is a member of the EGFR (HER, ErbB) subfamily of proteins, which are receptor PTKs (RTKs) containing an extracellular EGF-related ligand-binding region, a transmembrane helix, and a cytoplasmic region with a tyr kinase domain and a regulatory C-terminal tail. Unlike other PTKs, phosphorylation of the activation loop of EGFR proteins is not critical to their activation. Instead, they are activated by ligand-induced dimerization, leading to the phosphorylation of tyr residues in the C-terminal tail, which serve as binding sites for downstream signaling molecules. HER2 does not bind to any known EGFR subfamily ligands, but contributes to the kinase activity of all possible heterodimers. It acts as the preferred partner of other ligand-bound EGFR proteins and functions as a signal amplifier, with the HER2-HER3 heterodimer being the most potent pair in mitogenic signaling. HER2 plays an important role in cell development, proliferation, survival and motility. Overexpression of HER2 results in its activation and downstream signaling, even in the absence of ligand. HER2 overexpression, mainly due to gene amplification, has been shown in a variety of human cancers. Its role in breast cancer is especially well-documented. HER2 is up-regulated in about 25% of breast tumors and is associated with increases in tumor aggressiveness, recurrence and mortality. HER2 is a target for monoclonal antibodies and small molecule inhibitors, which are being developed as treatments for cancer. The first humanized antibody approved for clinical use is Trastuzumab (Herceptin), which is being used in combination with other therapies to improve the survival rates of patients with HER2-overexpressing breast cancer. The HER2 subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Protein Tyrosine Kinase, Tie1; Protein Tyrosine Kinase (PTK) family; Tie1; catalytic (c) domain. The PTKc family is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, and phosphoinositide 3-kinase (PI3K). PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Tie1 is a receptor tyr kinase (RTK) containing an extracellular region, a transmembrane segment, and an intracellular catalytic domain. The extracellular region contains an immunoglobulin (Ig)-like domain, three epidermal growth factor (EGF)-like domains, a second Ig-like domain, and three fibronectin type III repeats. Tie receptors are specifically expressed in endothelial cells and hematopoietic stem cells. No specific ligand has been identified for Tie1, although the angiopoietin, Ang-1, binds to Tie1 through integrins at high concentrations. In vivo studies of Tie1 show that it is critical in vascular development.

283-534 3.32e-68

Catalytic domain of the Protein Tyrosine Kinases, Class EphA Ephrin Receptors; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. This subfamily is composed of most class EphA receptors including EphA3, EphA4, EphA5, and EphA7, but excluding EphA1, EphA2 and EphA10. Class EphA receptors bind GPI-anchored ephrin-A ligands. There are ten vertebrate EphA receptors (EphA1-10), which display promiscuous interactions with six ephrin-A ligands. One exception is EphA4, which also binds ephrins-B2/B3. EphA receptors and ephrin-A ligands are expressed in multiple areas of the developing brain, especially in the retina and tectum. They are part of a system controlling retinotectal mapping. EphRs comprise the largest subfamily of receptor PTKs (RTKs). EphRs contain an ephrin-binding domain and two fibronectin repeats extracellularly, a transmembrane segment, and a cytoplasmic tyr kinase domain. Binding of the ephrin ligand to EphR requires cell-cell contact since both are anchored to the plasma membrane. The resulting downstream signals occur bidirectionally in both EphR-expressing cells (forward signaling) and ephrin-expressing cells (reverse signaling). Ephrin/EphR interaction mainly results in cell-cell repulsion or adhesion, making it important in neural development and plasticity, cell morphogenesis, cell-fate determination, embryonic development, tissue patterning, and angiogenesis. The EphA subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-542 5.89e-68

Catalytic domain of Tie Protein Tyrosine Kinases; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Tie proteins, consisting of Tie1 and Tie2, are receptor PTKs (RTKs) containing an extracellular region, a transmembrane segment, and an intracellular catalytic domain. The extracellular region contains an immunoglobulin (Ig)-like domain, three epidermal growth factor (EGF)-like domains, a second Ig-like domain, and three fibronectin type III repeats. Tie receptors are specifically expressed in endothelial cells and hematopoietic stem cells. The angiopoietins (Ang-1 to Ang-4) serve as ligands for Tie2, while no specific ligand has been identified for Tie1. The binding of Ang-1 to Tie2 leads to receptor autophosphorylation and activation, promoting cell migration and survival. In contrast, Ang-2 binding to Tie2 does not result in the same response, suggesting that Ang-2 may function as an antagonist. In vivo studies of Tie1 show that it is critical in vascular development. The Tie subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Protein Tyrosine Kinases, Vascular Endothelial Growth Factor Receptors; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. The VEGFR subfamily consists of VEGFR1 (Flt1), VEGFR2 (Flk1), VEGFR3 (Flt4), and similar proteins. VEGFR subfamily members are receptor PTKss (RTKs) containing an extracellular ligand-binding region with seven immunoglobulin (Ig)-like domains, a transmembrane segment, and an intracellular catalytic domain. In VEGFR3, the fifth Ig-like domain is replaced by a disulfide bridge. The binding of VEGFRs to their ligands, the VEGFs, leads to receptor dimerization, activation, and intracellular signaling. There are five VEGF ligands in mammals, which bind, in an overlapping pattern to the three VEGFRs, which can form homo or heterodimers. VEGFRs regulate the cardiovascular system. They are critical for vascular development during embryogenesis and blood vessel formation in adults. They induce cellular functions common to other growth factor receptors such as cell migration, survival, and proliferation. The VEGFR subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Protein Tyrosine Kinase, Fibroblast Growth Factor Receptor 3; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Many FGFR3 splice variants have been reported with the IIIb and IIIc isoforms being the predominant forms. FGFR3 IIIc is the isoform expressed in chondrocytes, the cells affected in dwarfism, while IIIb is expressed in epithelial cells. FGFR3 ligands include FGF1, FGF2, FGF4, FGF8, FGF9, and FGF23. It is a negative regulator of long bone growth. In the cochlear duct and in the lens, FGFR3 is involved in differentiation while it appears to have a role in cell proliferation in epithelial cells. Germline mutations in FGFR3 are associated with skeletal disorders including several forms of dwarfism. Some missense mutations are associated with multiple myeloma and carcinomas of the bladder and cervix. Overexpression of FGFR3 is found in thyroid carcinoma. FGFR3 is part of the FGFR subfamily, which are receptor PTKs (RTKs) containing an extracellular ligand-binding region with three immunoglobulin-like domains, a transmembrane segment, and an intracellular catalytic domain. The binding of FGFRs to their ligands, the FGFs, results in receptor dimerization and activation, and intracellular signaling. The binding of FGFs to FGFRs is promiscuous, in that a receptor may be activated by several ligands and a ligand may bind to more that one type of receptor. The FGFR3 subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Protein Tyrosine Kinases, Class EphB Ephrin Receptors; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Class EphB receptors bind to transmembrane ephrin-B ligands. There are six vertebrate EphB receptors (EphB1-6), which display promiscuous interactions with three ephrin-B ligands. One exception is EphB2, which also interacts with ephrin A5. EphB receptors play important roles in synapse formation and plasticity, spine morphogenesis, axon guidance, and angiogenesis. In the intestinal epithelium, EphBs are Wnt signaling target genes that control cell compartmentalization. They function as suppressors of colon cancer progression. EphRs comprise the largest subfamily of receptor PTKs (RTKs). They contain an ephrin-binding domain and two fibronectin repeats extracellularly, a transmembrane segment, and a cytoplasmic tyr kinase domain. Binding of the ephrin ligand to EphR requires cell-cell contact since both are anchored to the plasma membrane. The resulting downstream signals occur bidirectionally in both EphR-expressing cells (forward signaling) and ephrin-expressing cells (reverse signaling).

285-544 2.98e-67

Pseudokinase domain of Ryk (Receptor related to tyrosine kinase); Ryk is a receptor tyr kinase (RTK) containing an extracellular region with two leucine-rich motifs, a transmembrane segment, and an intracellular inactive pseudokinase domain, which shows similarity to tyr kinases but lacks crucial residues for catalytic activity and ATP binding. The extracellular region of Ryk shows homology to the N-terminal domain of Wnt inhibitory factor-1 (WIF) and serves as the ligand (Wnt) binding domain of Ryk. Ryk is expressed in many different tissues both during development and in adults, suggesting a widespread function. It acts as a chemorepulsive axon guidance receptor of Wnt glycoproteins and is responsible for the establishment of axon tracts during the development of the central nervous system. In addition, studies in mice reveal that Ryk is essential in skeletal, craniofacial, and cardiac development. Thus, it appears Ryk is involved in signal transduction despite its lack of kinase activity. Ryk may function as an accessory protein that modulates the signals coming from catalytically active partner RTKs such as the Eph receptors. The Ryk subfamily is part of a larger superfamily that includes other pseudokinases and the catalytic domains of active kinases including PTKs, protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

276-534 3.32e-66

Catalytic domain of the Protein Tyrosine Kinase, Fibroblast Growth Factor Receptor 1; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Alternative splicing of FGFR1 transcripts produces a variety of isoforms, which are differentially expressed in cells. FGFR1 binds the ligands, FGF1 and FGF2, with high affinity and has also been reported to bind FGF4, FGF6, and FGF9. FGFR1 signaling is critical in the control of cell migration during embryo development. It promotes cell proliferation in fibroblasts. Nuclear FGFR1 plays a role in the regulation of transcription. Mutations, insertions or deletions of FGFR1 have been identified in patients with Kallman's syndrome (KS), an inherited disorder characterized by hypogonadotropic hypogonadism and loss of olfaction. Aberrant FGFR1 expression has been found in some human cancers including 8P11 myeloproliferative syndrome (EMS), breast cancer, and pancreatic adenocarcinoma. FGFR1 is part of the FGFR subfamily, which are receptor PTKs (RTKs) containing an extracellular ligand-binding region with three immunoglobulin-like domains, a transmembrane segment, and an intracellular catalytic domain. The binding of FGFRs to their ligands, the FGFs, results in receptor dimerization and activation, and intracellular signaling. The binding of FGFs to FGFRs is promiscuous, in that a receptor may be activated by several ligands and a ligand may bind to more that one type of receptor. The FGFR1 subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

281-546 1.27e-65

Catalytic domain of the Protein Tyrosine Kinase, Insulin Receptor; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. InsR is a receptor PTK (RTK) that is composed of two alphabeta heterodimers. Binding of the insulin ligand to the extracellular alpha subunit activates the intracellular tyr kinase domain of the transmembrane beta subunit. Receptor activation leads to autophosphorylation, stimulating downstream kinase activities, which initiate signaling cascades and biological function. InsR signaling plays an important role in many cellular processes including glucose homeostasis, glycogen synthesis, lipid and protein metabolism, ion and amino acid transport, cell cycle and proliferation, cell differentiation, gene transcription, and nitric oxide synthesis. Insulin resistance, caused by abnormalities in InsR signaling, has been described in diabetes, hypertension, cardiovascular disease, metabolic syndrome, heart failure, and female infertility. The InsR subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Protein Tyrosine Kinase, Tropomyosin Related Kinase A; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. TrkA is a receptor PTK (RTK) containing an extracellular region with arrays of leucine-rich motifs flanked by two cysteine-rich clusters followed by two immunoglobulin-like domains, a transmembrane segment, and an intracellular catalytic domain. Binding of TrkA to its ligand, nerve growth factor (NGF), results in receptor oligomerization and activation of the catalytic domain. TrkA is expressed mainly in neural-crest-derived sensory and sympathetic neurons of the peripheral nervous system, and in basal forebrain cholinergic neurons of the central nervous system. It is critical for neuronal growth, differentiation and survival. Alternative TrkA splicing has been implicated as a pivotal regulator of neuroblastoma (NB) behavior. Normal TrkA expression is associated with better NB prognosis, while the hypoxia-regulated TrkAIII splice variant promotes NB pathogenesis and progression. Aberrant TrkA expression has also been demonstrated in non-neural tumors including prostate, breast, lung, and pancreatic cancers. The TrkA subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Protein Tyrosine Kinase, Zeta-chain-associated protein of 70kDa; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Zap-70 is a cytoplasmic (or nonreceptor) PTK containing two Src homology 2 (SH2) domains N-terminal to the catalytic tyr kinase domain. Zap-70 is primarily expressed in T-cells and NK cells, and is a crucial component in T-cell receptor (TCR) signaling. Zap-70 binds the phosphorylated ITAM (immunoreceptor tyr activation motif) sequences of the activated TCR zeta-chain through its SH2 domains, leading to its phosphorylation and activation. It then phosphorylates target proteins, which propagate the signals to downstream pathways. Zap-70 is hardly detected in normal peripheral B-cells, but is present in some B-cell malignancies. It is used as a diagnostic marker for chronic lymphocytic leukemia (CLL) as it is associated with the more aggressive subtype of the disease. The Zap-70 subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

282-537 2.86e-65

Catalytic domain of the Protein Tyrosine Kinase, Discoidin Domain Receptor 2; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. DDR2 is a receptor PTK (RTK) containing an extracellular discoidin homology domain, a transmembrane segment, an extended juxtamembrane region, and an intracellular catalytic domain. The binding of the ligand, collagen, to DDR2 results in a slow but sustained receptor activation. DDR2 binds mostly to fibrillar collagens as well as collagen X. DDR2 is widely expressed in many tissues with the highest levels found in skeletal muscle, skin, kidney and lung. It is important in cell proliferation and development. Mice, with a deletion of DDR2, suffer from dwarfism and delayed healing of epidermal wounds. DDR2 also contributes to collagen (type I) regulation by inhibiting fibrillogenesis and altering the morphology of collagen fibers. It is also expressed in immature dendritic cells (DCs), where it plays a role in DC activation and function. The DDR2 subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase (PI3K).

282-541 1.48e-64

Catalytic domain of Discoidin Domain Receptor-like Protein Tyrosine Kinases; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. DDR-like proteins are members of the DDR subfamily, which are receptor PTKs (RTKs) containing an extracellular discoidin homology domain, a transmembrane segment, an extended juxtamembrane region, and an intracellular catalytic domain. The binding of the ligand, collagen, to DDRs results in a slow but sustained receptor activation. DDRs regulate cell adhesion, proliferation, and extracellular matrix remodeling. They have been linked to a variety of human cancers including breast, colon, ovarian, brain, and lung. There is no evidence showing that DDRs act as transforming oncogenes. They are more likely to play a role in the regulation of tumor growth and metastasis. The DDR-like subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

283-545 9.94e-64

Catalytic domain of the Protein Tyrosine Kinase, HER4; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. HER4 (ErbB4) is a member of the EGFR (HER, ErbB) subfamily of proteins, which are receptor PTKs (RTKs) containing an extracellular EGF-related ligand-binding region, a transmembrane helix, and a cytoplasmic region with a tyr kinase domain and a regulatory C-terminal tail. Unlike other PTKs, phosphorylation of the activation loop of EGFR proteins is not critical to their activation. Instead, they are activated by ligand-induced dimerization, leading to the phosphorylation of tyr residues in the C-terminal tail, which serve as binding sites for downstream signaling molecules. Ligands that bind HER4 fall into two groups, the neuregulins (or heregulins) and some EGFR (HER1) ligands including betacellulin, HBEGF, and epiregulin. All four neuregulins (NRG1-4) interact with HER4. Upon ligand binding, HER4 forms homo- or heterodimers with other HER proteins. HER4 is essential in embryonic development. It is implicated in mammary gland, cardiac, and neural development. As a postsynaptic receptor of NRG1, HER4 plays an important role in synaptic plasticity and maturation. The impairment of NRG1/HER4 signaling may contribute to schizophrenia. The HER4 subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-540 5.96e-63

Pseudokinase domain of the Protein Tyrosine Kinase, Colon Carcinoma Kinase 4; CCK4, also called protein tyrosine kinase 7 (PTK7), is an orphan receptor PTK (RTK) containing an extracellular region with seven immunoglobulin domains, a transmembrane segment, and an intracellular inactive pseudokinase domain, which shows similarity to tyr kinases but lacks crucial residues for catalytic activity and ATP binding. Studies in mice reveal that CCK4 is essential for neural development. Mouse embryos containing a truncated CCK4 die perinatally and display craniorachischisis, a severe form of neural tube defect. The mechanism of action of the CCK4 pseudokinase is still unknown. Other pseudokinases such as HER3 rely on the activity of partner RTKs. The CCK4 subfamily is part of a larger superfamily that includes other pseudokinases and the catalytic domains of active kinases including PTKs, protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Protein Tyrosine Kinase, Receptor tyrosine kinase-like Orphan Receptor 1; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Ror kinases are expressed in many tissues during development. Avian Ror1 was found to be involved in late limb development. Studies in mice reveal that Ror1 is important in the regulation of neurite growth in central neurons, as well as in respiratory development. Loss of Ror1 also enhances the heart and skeletal abnormalities found in Ror2-deficient mice. Ror proteins are orphan receptor PTKs (RTKs) containing an extracellular region with immunoglobulin-like, cysteine-rich, and kringle domains, a transmembrane segment, and an intracellular catalytic domain. Ror RTKs are unrelated to the nuclear receptor subfamily called retinoid-related orphan receptors (RORs). RTKs are usually activated through ligand binding, which causes dimerization and autophosphorylation of the intracellular tyr kinase catalytic domain. The Ror1 subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Protein Tyrosine Kinase, Colony-Stimulating Factor-1 Receptor; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. CSF-1R, also called c-Fms, is a member of the Platelet Derived Growth Factor Receptor (PDGFR) subfamily of proteins, which are receptor PTKs (RTKs) containing an extracellular ligand-binding region with five immunoglobulin-like domains, a transmembrane segment, and an intracellular catalytic domain. The binding of CSF-1R to its ligand, CSF-1, leads to receptor dimerization, trans phosphorylation and activation, and intracellular signaling. CSF-1R signaling is critical in the regulation of macrophages and osteoclasts. It leads to increases in gene transcription and protein translation, and induces cytoskeletal remodeling. CSF-1R signaling leads to a variety of cellular responses including survival, proliferation, and differentiation of target cells. It plays an important role in innate immunity, tissue development and function, and the pathogenesis of some diseases including atherosclerosis and cancer. CSF-1R signaling is also implicated in mammary gland development during pregnancy and lactation. Aberrant CSF-1/CSF-1R expression correlates with tumor cell invasiveness, poor clinical prognosis, and bone metastasis in breast cancer. Although the structure of the human CSF-1R catalytic domain is known, it is excluded from this specific alignment model because it contains a deletion in its sequence. The CSF-1R subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

282-536 6.34e-61

Catalytic domain of the Protein Tyrosine Kinase, Discoidin Domain Receptor 1; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. DDR1 is a receptor PTK (RTK) containing an extracellular discoidin homology domain, a transmembrane segment, an extended juxtamembrane region, and an intracellular catalytic domain. The binding of the ligand, collagen, to DDR1 results in a slow but sustained receptor activation. DDR1 binds to all collagens tested to date (types I-IV). It is widely expressed in many tissues. It is abundant in the brain and is also found in keratinocytes, colonic mucosa epithelium, lung epithelium, thyroid follicles, and the islets of Langerhans. During embryonic development, it is found in the developing neuroectoderm. DDR1 is a key regulator of cell morphogenesis, differentiation and proliferation. It is important in the development of the mammary gland, the vasculator and the kidney. DDR1 is also found in human leukocytes, where it facilitates cell adhesion, migration, maturation, and cytokine production. The DDR1 subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

169-262 9.93e-61

Src homology 2 (SH2) domain found in Abelson murine lymphosarcoma virus (ABL) proteins; ABL-family proteins are highly conserved tyrosine kinases. Each ABL protein contains an SH3-SH2-TK (Src homology 3-Src homology 2-tyrosine kinase) domain cassette, which confers autoregulated kinase activity and is common among nonreceptor tyrosine kinases. Several types of posttranslational modifications control ABL catalytic activity, subcellular localization, and stability, with consequences for both cytoplasmic and nuclear ABL functions. Binding partners provide additional regulation of ABL catalytic activity, substrate specificity, and downstream signaling. By combining this cassette with actin-binding and -bundling domain, ABL proteins are capable of connecting phosphoregulation with actin-filament reorganization. Vertebrate paralogs, ABL1 and ABL2, have evolved to perform specialized functions. ABL1 includes nuclear localization signals and a DNA binding domain which is used to mediate DNA damage-repair functions, while ABL2 has additional binding capacity for actin and for microtubules to enhance its cytoskeletal remodeling functions. SH2 is involved in several autoinhibitory mechanism that constrain the enzymatic activity of the ABL-family kinases. In one mechanism SH2 and SH3 cradle the kinase domain while a cap sequence stabilizes the inactive conformation resulting in a locked inactive state. Another involves phosphatidylinositol 4,5-bisphosphate (PIP2) which binds the SH2 domain through residues normally required for phosphotyrosine binding in the linker segment between the SH2 and kinase domains. The SH2 domain contributes to ABL catalytic activity and target site specificity. It is thought that the ABL catalytic site and SH2 pocket have coevolved to recognize the same sequences. Recent work now supports a hierarchical processivity model in which the substrate target site most compatible with ABL kinase domain preferences is phosphorylated with greatest efficiency. If this site is compatible with the ABL SH2 domain specificity, it will then reposition and dock in the SH2 pocket. This mechanism also explains how ABL kinases phosphorylates poor targets on the same substrate if they are properly positioned and how relatively poor substrate proteins might be recruited to ABL through a complex with strong substrates that can also dock with the SH2 pocket. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

281-534 7.37e-60

Catalytic domain of the Protein Tyrosine Kinase, Insulin-like Growth Factor-1 Receptor; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. IGF-1R is a receptor PTK (RTK) that is composed of two alphabeta heterodimers. Binding of the ligand (IGF-1 or IGF-2) to the extracellular alpha subunit activates the intracellular tyr kinase domain of the transmembrane beta subunit. Receptor activation leads to autophosphorylation, which stimulates downstream kinase activities and biological function. IGF-1R signaling is important in the differentiation, growth, and survival of normal cells. In cancer cells, where it is frequently overexpressed, IGF-1R is implicated in proliferation, the suppression of apoptosis, invasion, and metastasis. IGF-1R is being developed as a therapeutic target in cancer treatment. The IGF-1R subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

283-545 2.42e-59

Catalytic domain of the Protein Tyrosine Kinase, Tie2; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Tie2 is a receptor PTK (RTK) containing an extracellular region, a transmembrane segment, and an intracellular catalytic domain. The extracellular region contains an immunoglobulin (Ig)-like domain, three epidermal growth factor (EGF)-like domains, a second Ig-like domain, and three fibronectin type III repeats. Tie2 is expressed mainly in endothelial cells and hematopoietic stem cells. It is also found in a subset of tumor-associated monocytes and eosinophils. The angiopoietins (Ang-1 to Ang-4) serve as ligands for Tie2. The binding of Ang-1 to Tie2 leads to receptor autophosphorylation and activation, promoting cell migration and survival. In contrast, Ang-2 binding to Tie2 does not result in the same response, suggesting that Ang-2 may function as an antagonist. Tie2 signaling plays key regulatory roles in vascular integrity and quiescence, and in inflammation. The Tie2 subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Protein Tyrosine Kinase, Tropomyosin Related Kinase C; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. TrkC is a receptor PTK (RTK) containing an extracellular region with arrays of leucine-rich motifs flanked by two cysteine-rich clusters followed by two immunoglobulin-like domains, a transmembrane segment, and an intracellular catalytic domain. Binding of TrkC to its ligand, neurotrophin 3 (NT3), results in receptor oligomerization and activation of the catalytic domain. TrkC is broadly expressed in the nervous system and in some non-neural tissues including the developing heart. NT3/TrkC signaling plays an important role in the innervation of the cardiac conducting system and the development of smooth muscle cells. Mice deficient with NT3 and TrkC have multiple heart defects. NT3/TrkC signaling is also critical for the development and maintenance of enteric neurons that are important for the control of gut peristalsis. The TrkC subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

276-540 7.38e-58

Catalytic domain of the Protein Tyrosine Kinase, Kit; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Kit is important in the development of melanocytes, germ cells, mast cells, hematopoietic stem cells, the interstitial cells of Cajal, and the pacemaker cells of the GI tract. Kit signaling is involved in major cellular functions including cell survival, proliferation, differentiation, adhesion, and chemotaxis. Mutations in Kit, which result in constitutive ligand-independent activation, are found in human cancers such as gastrointestinal stromal tumor (GIST) and testicular germ cell tumor (TGCT). The aberrant expression of Kit and/or SCF is associated with other tumor types such as systemic mastocytosis and cancers of the breast, neurons, lung, prostate, colon, and rectum. Although the structure of the human Kit catalytic domain is known, it is excluded from this specific alignment model because it contains a deletion in its sequence. Kit is a member of the Platelet Derived Growth Factor Receptor (PDGFR) subfamily of proteins, which are receptor PTKs (RTKs) containing an extracellular ligand-binding region with five immunoglobulin-like domains, a transmembrane segment, and an intracellular catalytic domain. The binding of Kit to its ligand, the stem-cell factor (SCF), leads to receptor dimerization, trans phosphorylation and activation, and intracellular signaling. The Kit subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

283-548 1.09e-57

Catalytic domain of the Protein Tyrosine Kinase, Tropomyosin Related Kinase B; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. TrkB is a receptor PTK (RTK) containing an extracellular region with arrays of leucine-rich motifs flanked by two cysteine-rich clusters followed by two immunoglobulin-like domains, a transmembrane segment, and an intracellular catalytic domain. Binding of TrkB to its ligands, brain-derived neurotrophic factor (BDNF) or neurotrophin 4 (NT4), results in receptor oligomerization and activation of the catalytic domain. TrkB is broadly expressed in the nervous system and in some non-neural tissues. It plays important roles in cell proliferation, differentiation, and survival. BDNF/Trk signaling plays a key role in regulating activity-dependent synaptic plasticity. TrkB also contributes to protection against gp120-induced neuronal cell death. TrkB overexpression is associated with poor prognosis in neuroblastoma (NB) and other human cancers. It acts as a suppressor of anoikis (detachment-induced apoptosis) and contributes to tumor metastasis. The TrkB subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

292-534 4.32e-57

Catalytic (repeat 2) domain of the Protein Tyrosine Kinase, Janus kinase 2; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Jak2 is widely expressed in many tissues and is essential for the signaling of hormone-like cytokines such as growth hormone, erythropoietin, thrombopoietin, and prolactin, as well as some IFNs and cytokines that signal through the IL-3 and gp130 receptors. Disruption of Jak2 in mice results in an embryonic lethal phenotype with multiple defects including erythropoietic and cardiac abnormalities. It is the only Jak gene that results in a lethal phenotype when disrupted in mice. A mutation in the pseudokinase domain of Jak2, V617F, is present in many myeloproliferative diseases, including almost all patients with polycythemia vera, and 50% of patients with essential thrombocytosis and myelofibrosis. Jak2 is a member of the Janus kinase (Jak) subfamily of proteins, which are cytoplasmic (or nonreceptor) PTKs containing an N-terminal FERM domain, followed by a Src homology 2 (SH2) domain, a pseudokinase domain, and a C-terminal catalytic tyr kinase domain. Jaks are crucial for cytokine receptor signaling. They are activated by autophosphorylation upon cytokine-induced receptor aggregation, and subsequently trigger downstream signaling events such as the phosphorylation of signal transducers and activators of transcription (STATs). The PTKc family is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

282-542 5.23e-57

Catalytic domain of the Protein Tyrosine Kinase, Ephrin Receptor A10; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. EphA10, which contains an inactive tyr kinase domain, may function to attenuate signals of co-clustered active receptors. EphA10 is mainly expressed in the testis. Ephrin/EphR interaction results in cell-cell repulsion or adhesion, making it important in neural development and plasticity, cell morphogenesis, cell-fate determination, embryonic development, tissue patterning, and angiogenesis. EphRs comprise the largest subfamily of receptor tyr kinases (RTKs). In general, class EphA receptors bind GPI-anchored ephrin-A ligands. There are ten vertebrate EphA receptors (EphA1-10), which display promiscuous interactions with six ephrin-A ligands. EphRs contain an ephrin binding domain and two fibronectin repeats extracellularly, a transmembrane segment, and a cytoplasmic tyr kinase domain. Binding of the ephrin ligand to EphR requires cell-cell contact since both are anchored to the plasma membrane. The resulting downstream signals occur bidirectionally in both EphR-expressing cells (forward signaling) and ephrin-expressing cells (reverse signaling). The EphA10 subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-545 3.22e-56

Pseudokinase domain of the Protein Tyrosine Kinase, HER3; HER3 (ErbB3) is a member of the EGFR (HER, ErbB) subfamily of proteins, which are receptor PTKs (RTKs) containing an extracellular EGF-related ligand-binding region, a transmembrane helix, and a cytoplasmic region with a tyr kinase domain and a regulatory C-terminal tail. Unlike other PTKs, phosphorylation of the activation loop of EGFR proteins is not critical to their activation. Instead, they are activated by ligand-induced dimerization, leading to the phosphorylation of tyr residues in the C-terminal tail, which serve as binding sites for downstream signaling molecules. HER3 contains an impaired tyr kinase domain, which lacks crucial residues for catalytic activity against exogenous substrates but is still able to bind ATP and autophosphorylate. HER3 binds the neuregulin ligands, NRG1 and NRG2, and it relies on its heterodimerization partners for activity following ligand binding. The HER2-HER3 heterodimer constitutes a high affinity co-receptor capable of potent mitogenic signaling. HER3 participates in a signaling pathway involved in the proliferation, survival, adhesion, and motility of tumor cells. The HER3 subfamily is part of a larger superfamily that includes other pseudokinases and the the catalytic domains of active kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-534 1.29e-54

Catalytic domain of Protein Kinases; PKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine or tyrosine residues on protein substrates. PKs make up a large family of serine/threonine kinases (STKs), protein tyrosine kinases (PTKs), and dual-specificity PKs that phosphorylate both serine/threonine and tyrosine residues of target proteins. Majority of protein phosphorylation occurs on serine residues while only 1% occurs on tyrosine residues. Protein phosphorylation is a mechanism by which a wide variety of cellular proteins, such as enzymes and membrane channels, are reversibly regulated in response to certain stimuli. PKs often function as components of signal transduction pathways in which one kinase activates a second kinase, which in turn, may act on other kinases; this sequential action transmits a signal from the cell surface to target proteins, which results in cellular responses. The PK family is one of the largest known protein families with more than 100 homologous yeast enzymes and more than 500 human proteins. A fraction of PK family members are pseudokinases that lack crucial residues for catalytic activity. The mutiplicity of kinases allows for specific regulation according to substrate, tissue distribution, and cellular localization. PKs regulate many cellular processes including proliferation, division, differentiation, motility, survival, metabolism, cell-cycle progression, cytoskeletal rearrangement, immunity, and neuronal functions. Many kinases are implicated in the development of various human diseases including different types of cancer. The PK family is part of a larger superfamily that includes the catalytic domains of RIO kinases, aminoglycoside phosphotransferase, choline kinase, phosphoinositide 3-kinase (PI3K), and actin-fragmin kinase.

Catalytic domain of the Protein Tyrosine Kinase, Receptor tyrosine kinase-like Orphan Receptor 2; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Ror2 plays important roles in skeletal and heart formation. Ror2-deficient mice show widespread bone abnormalities, ventricular defects in the heart, and respiratory dysfunction. Mutations in human Ror2 result in two different bone development genetic disorders, recessive Robinow syndrome and brachydactyly type B. Ror2 is also implicated in neural development. Ror proteins are orphan receptor PTKs (RTKs) containing an extracellular region with immunoglobulin-like, cysteine-rich, and kringle domains, a transmembrane segment, and an intracellular catalytic domain. Ror RTKs are unrelated to the nuclear receptor subfamily called retinoid-related orphan receptors (RORs). RTKs are usually activated through ligand binding, which causes dimerization and autophosphorylation of the intracellular tyr kinase catalytic domain. The Ror2 subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Protein Tyrosine Kinase, Vascular Endothelial Growth Factor Receptor 3; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. VEGFR3 (or Flt4) preferentially binds the ligands VEGFC and VEGFD. VEGFR3 is essential for lymphatic endothelial cell (EC) development and function. It has been shown to regulate adaptive immunity during corneal transplantation. VEGFR3 is upregulated on blood vascular ECs in pathological conditions such as vascular tumors and the periphery of solid tumors. It plays a role in cancer progression and lymph node metastasis. Missense mutations in the VEGFR3 gene are associated with primary human lymphedema. VEGFR3 is a member of the VEGFR subfamily of proteins, which are receptor PTKs (RTKs) containing an extracellular ligand-binding region with seven immunoglobulin (Ig)-like domains, a transmembrane segment, and an intracellular catalytic domain. In VEGFR3, the fifth Ig-like domain is replaced by a disulfide bridge. The binding of VEGFRs to their ligands, the VEGFs, leads to receptor dimerization, activation, and intracellular signaling. The VEGFR3 subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-534 9.60e-54

Catalytic (repeat 2) domain of the Protein Tyrosine Kinase, Janus kinase 3; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Jak3 is expressed only in hematopoietic cells. It binds the shared receptor subunit common gamma chain and thus, is essential in the signaling of cytokines that use it such as IL-2, IL-4, IL-7, IL-9, IL-15, and IL-21. Jak3 is important in lymphoid development and myeloid cell differentiation. Inactivating mutations in Jak3 have been reported in humans with severe combined immunodeficiency (SCID). Jak3 is a member of the Janus kinase (Jak) subfamily of proteins, which are cytoplasmic (or nonreceptor) PTKs containing an N-terminal FERM domain, followed by a Src homology 2 (SH2) domain, a pseudokinase domain, and a C-terminal catalytic tyr kinase domain. Jaks are crucial for cytokine receptor signaling. They are activated by autophosphorylation upon cytokine-induced receptor aggregation, and subsequently trigger downstream signaling events such as the phosphorylation of signal transducers and activators of transcription (STATs). The PTKc family is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

274-534 4.54e-53

Catalytic domain of the Protein Tyrosine Kinase, Platelet Derived Growth Factor Receptor beta; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. PDGFR beta is a receptor PTK (RTK) containing an extracellular ligand-binding region with five immunoglobulin-like domains, a transmembrane segment, and an intracellular catalytic domain. The binding to its ligands, the PDGFs, leads to receptor dimerization, trans phosphorylation and activation, and intracellular signaling. PDGFR beta forms homodimers or heterodimers with PDGFR alpha, depending on the nature of the PDGF ligand. PDGF-BB and PDGF-DD induce PDGFR beta homodimerization. PDGFR signaling plays many roles in normal embryonic development and adult physiology. PDGFR beta signaling leads to a variety of cellular effects including the stimulation of cell growth and chemotaxis, as well as the inhibition of apoptosis and GAP junctional communication. It is critical in normal angiogenesis as it is involved in the recruitment of pericytes and smooth muscle cells essential for vessel stability. Aberrant PDGFR beta expression is associated with some human cancers. The continuously-active fusion proteins of PDGFR beta with COL1A1 and TEL are associated with dermatofibrosarcoma protuberans (DFSP) and a subset of chronic myelomonocytic leukemia (CMML), respectively. The PDGFR beta subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

276-543 1.67e-52

Catalytic domain of the Protein Tyrosine Kinase, Platelet Derived Growth Factor Receptor alpha; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. PDGFR alpha is a receptor PTK (RTK) containing an extracellular ligand-binding region with five immunoglobulin-like domains, a transmembrane segment, and an intracellular catalytic domain. The binding to its ligands, the PDGFs, leads to receptor dimerization, trans phosphorylation and activation, and intracellular signaling. PDGFR alpha forms homodimers or heterodimers with PDGFR beta, depending on the nature of the PDGF ligand. PDGF-AA, PDGF-AB, and PDGF-CC induce PDGFR alpha homodimerization. PDGFR signaling plays many roles in normal embryonic development and adult physiology. PDGFR alpha signaling is important in the formation of lung alveoli, intestinal villi, mesenchymal dermis, and hair follicles, as well as in the development of oligodendrocytes, retinal astrocytes, neural crest cells, and testicular cells. Aberrant PDGFR alpha expression is associated with some human cancers. Mutations in PDGFR alpha have been found within a subset of gastrointestinal stromal tumors (GISTs). An active fusion protein FIP1L1-PDGFR alpha, derived from interstitial deletion, is associated with idiopathic hypereosinophilic syndrome and chronic eosinophilic leukemia. The PDGFR alpha subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic (repeat 2) domain of the Protein Tyrosine Kinase, Janus kinase 1; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Jak1 is widely expressed in many tissues. Many cytokines are dependent on Jak1 for signaling, including those that use the shared receptor subunits common gamma chain (IL-2, IL-4, IL-7, IL-9, IL-15, IL-21) and gp130 (IL-6, IL-11, oncostatin M, G-CSF, and IFNs, among others). The many varied interactions of Jak1 and its ubiquitous expression suggest many biological roles. Jak1 is important in neurological development, as well as in lymphoid development and function. It also plays a role in the pathophysiology of cardiac hypertrophy and heart failure. A mutation in the ATP-binding site of Jak1 was identified in a human uterine leiomyosarcoma cell line, resulting in defective cytokine induction and antigen presentation, thus allowing the tumor to evade the immune system. Jak1 is a member of the Janus kinase (Jak) subfamily of proteins, which are cytoplasmic (or nonreceptor) PTKs containing an N-terminal FERM domain, followed by a Src homology 2 (SH2) domain, a pseudokinase domain, and a C-terminal tyr kinase domain. Jaks are crucial for cytokine receptor signaling. They are activated by autophosphorylation upon cytokine-induced receptor aggregation, and subsequently trigger downstream signaling events such as the phosphorylation of signal transducers and activators of transcription (STATs). The Jak1 subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-532 1.02e-48

Catalytic domain of the Serine/Threonine Kinases, Mitogen-Activated Protein Kinase Kinase Kinases 12 and 13; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. MAP3K12 is also called MAPK upstream kinase (MUK), dual leucine zipper-bearing kinase (DLK) or leucine-zipper protein kinase (ZPK). It is involved in the c-Jun N-terminal kinase (JNK) pathway that directly regulates axonal regulation through the phosphorylation of microtubule-associated protein 1B (MAP1B). It also regulates the differentiation of many cell types including adipocytes and may play a role in adipogenesis. MAP3K13, also called leucine zipper-bearing kinase (LZK), directly phosphorylates and activates MKK7, which in turn activates the JNK pathway. It also activates NF-kB through IKK activation and this activity is enhanced by antioxidant protein-1 (AOP-1). MAP3Ks (MKKKs or MAPKKKs) phosphorylate and activate MAP2Ks (MAPKKs or MKKs), which in turn phosphorylate and activate MAPKs during signaling cascades that are important in mediating cellular responses to extracellular signals. The MAP3K12/13 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinases, Mixed Lineage Kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. MLKs act as mitogen-activated protein kinase kinase kinases (MAP3Ks, MKKKs, MAPKKKs), which phosphorylate and activate MAPK kinases (MAPKKs or MKKs or MAP2Ks), which in turn phosphorylate and activate MAPKs during signaling cascades that are important in mediating cellular responses to extracellular signals. Mammals have four MLKs (MLK1-4), mostly conserved in vertebrates, which contain an SH3 domain, a catalytic kinase domain, a leucine zipper, a proline-rich region, and a CRIB domain that mediates binding to GTP-bound Cdc42 and Rac. MLKs play roles in immunity and inflammation, as well as in cell death, proliferation, and cell cycle regulation. The MLK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Mixed lineage kinase-Like mitogen-activated protein Triple Kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. MLTK, also called zipper sterile-alpha-motif kinase (ZAK), contains a catalytic kinase domain and a leucine zipper. There are two alternatively-spliced variants, MLTK-alpha and MLTK-beta. MLTK-alpha contains a sterile-alpha-motif (SAM) at the C-terminus. MLTK regulates the c-Jun N-terminal kinase, extracellular signal-regulated kinase, p38 MAPK, and NF-kB pathways. ZAK is the MAP3K involved in the signaling cascade that leads to the ribotoxic stress response initiated by cellular damage due to Shiga toxins and ricin. It may also play a role in cell transformation and cancer development. MAP3Ks (MKKKs or MAPKKKs) phosphorylate and activate MAPK kinases (MAPKKs or MKKs or MAP2Ks), which in turn phosphorylate and activate MAPKs during signaling cascades that are important in mediating cellular responses to extracellular signals.The MLTK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic (repeat 2) domain of the Protein Tyrosine Kinase, Tyrosine kinase 2; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Tyk2 is widely expressed in many tissues. It is involved in signaling via the cytokine receptors IFN-alphabeta, IL-6, IL-10, IL-12, IL-13, and IL-23. It mediates cell surface urokinase receptor (uPAR) signaling and plays a role in modulating vascular smooth muscle cell (VSMC) functional behavior in response to injury. Tyk2 is also important in dendritic cell function and T helper (Th)1 cell differentiation. A homozygous mutation of Tyk2 was found in a patient with hyper-IgE syndrome (HIES), a primary immunodeficiency characterized by recurrent skin abscesses, pneumonia, and elevated serum IgE. This suggests that Tyk2 may play important roles in multiple cytokine signaling involved in innate and adaptive immunity. Tyk2 is a member of the Janus kinase (Jak) subfamily of proteins, which are cytoplasmic (or nonreceptor) PTKs containing an N-terminal FERM domain, followed by a Src homology 2 (SH2) domain, a pseudokinase domain, and a C-terminal tyr kinase catalytic domain. Jaks are crucial for cytokine receptor signaling. They are activated by autophosphorylation upon cytokine-induced receptor aggregation, and subsequently trigger downstream signaling events such as the phosphorylation of signal transducers and activators of transcription (STATs). The Tyk2 subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Protein Tyrosine Kinases, Apoptosis-associated tyrosine kinase 1; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Aatyk1 (or simply Aatyk) is also called lemur tyrosine kinase 1 (Lmtk1). It is a cytoplasmic (or nonreceptor) kinase containing a long C-terminal region. The expression of Aatyk1 is upregulated during growth arrest and apoptosis in myeloid cells. Aatyk1 has been implicated in neural differentiation, and is a regulator of the Na-K-2Cl cotransporter, a membrane protein involved in cell proliferation and survival, epithelial transport, and blood pressure control. The Aatyk1 subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Mixed Lineage Kinase 4; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. MLK4 is a mitogen-activated protein kinase kinase kinase (MAP3K, MKKK, MAPKKK), which phosphorylates and activates MAPK kinases (MAPKKs or MKKs or MAP2Ks), which in turn phosphorylate and activate MAPKs during signaling cascades that are important in mediating cellular responses to extracellular signals. The specific function of MLK4 is yet to be determined. Mutations in the kinase domain of MLK4 have been detected in colorectal cancers. Mammals have four MLKs, mostly conserved in vertebrates, which contain an SH3 domain, a catalytic kinase domain, a leucine zipper, a proline-rich region, and a CRIB domain that mediates binding to GTP-bound Cdc42 and Rac. MLKs play roles in immunity and inflammation, as well as in cell death, proliferation, and cell cycle regulation.The MLK4 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Mixed Lineage Kinase 2; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. MLK2 is a mitogen-activated protein kinase kinase kinase (MAP3K, MKKK, MAPKKK) and is also called MAP3K10. MAP3Ks phosphorylate and activate MAPK kinases (MAPKKs or MKKs or MAP2Ks), which in turn phosphorylate and activate MAPKs during signaling cascades that are important in mediating cellular responses to extracellular signals. MLK2 is abundant in brain, skeletal muscle, and testis. It functions upstream of the MAPK, c-Jun N-terminal kinase. It binds hippocalcin, a calcium-sensor protein that protects neurons against calcium-induced cell death. Both MLK2 and hippocalcin may be associated with the pathogenesis of Parkinson's disease. MLK2 also binds to normal huntingtin (Htt), which is important in neuronal transcription, development, and survival. MLK2 does not bind to the polyglutamine-expanded Htt, which is implicated in the pathogeneis of Huntington's disease, leading to neuronal toxicity. Mammals have four MLKs, mostly conserved in vertebrates, which contain an SH3 domain, a catalytic kinase domain, a leucine zipper, a proline-rich region, and a CRIB domain that mediates binding to GTP-bound Cdc42 and Rac. MLKs play roles in immunity and inflammation, as well as in cell death, proliferation, and cell cycle regulation. The MLK2 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase (PI3K).

Catalytic domain of the Serine/Threonine Kinase, Mixed Lineage Kinase 1; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. MLK1 is a mitogen-activated protein kinase kinase kinase (MAP3K, MKKK, MAPKKK) and is also called MAP3K9. MAP3Ks phosphorylate and activate MAPK kinases (MAPKKs or MKKs or MAP2Ks), which in turn phosphorylate and activate MAPKs during signaling cascades that are important in mediating cellular responses to extracellular signals. Little is known about the specific function of MLK1. It is capable of activating the c-Jun N-terminal kinase pathway. Mice lacking both MLK1 and MLK2 are viable, fertile, and have normal life spans. There could be redundancy in the function of MLKs. Mammals have four MLKs, mostly conserved in vertebrates, which contain an SH3 domain, a catalytic kinase domain, a leucine zipper, a proline-rich region, and a CRIB domain that mediates binding to GTP-bound Cdc42 and Rac.

292-535 1.54e-41

Catalytic domain of bacterial Serine/Threonine kinases, PknB and similar proteins; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. This subfamily includes many bacterial eukaryotic-type STKs including Staphylococcus aureus PknB (also called PrkC or Stk1), Bacillus subtilis PrkC, and Mycobacterium tuberculosis Pkn proteins (PknB, PknD, PknE, PknF, PknL, and PknH), among others. S. aureus PknB is the only eukaryotic-type STK present in this species, although many microorganisms encode for several such proteins. It is important for the survival and pathogenesis of S. aureus as it is involved in the regulation of purine and pyrimidine biosynthesis, cell wall metabolism, autolysis, virulence, and antibiotic resistance. M. tuberculosis PknB is essential for growth and it acts on diverse substrates including proteins involved in peptidoglycan synthesis, cell division, transcription, stress responses, and metabolic regulation. B. subtilis PrkC is located at the inner membrane of endospores and functions to trigger spore germination. Bacterial STKs in this subfamily show varied domain architectures. The well-characterized members such as S. aureus and M. tuberculosis PknB, and B. subtilis PrkC, contain an N-terminal cytosolic kinase domain, a transmembrane (TM) segment, and mutliple C-terminal extracellular PASTA domains. The PknB subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

287-542 1.64e-40

Catalytic domain of the Serine/Threonine Kinase, Mixed Lineage Kinase 3; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. MLK3 is a mitogen-activated protein kinase kinase kinases (MAP3K, MKKK, MAPKKK), which phosphorylates and activates MAPK kinases (MAPKKs or MKKs or MAP2Ks), which in turn phosphorylate and activate MAPKs during signaling cascades that are important in mediating cellular responses to extracellular signals. MLK3 activates multiple MAPK pathways and plays a role in apoptosis, proliferation, migration, and differentiation, depending on the cellular context. It is highly expressed in breast cancer cells and its signaling through c-Jun N-terminal kinase has been implicated in the migration, invasion, and malignancy of cancer cells. MLK3 also functions as a negative regulator of Inhibitor of Nuclear Factor-KappaB Kinase (IKK) and consequently, it also impacts inflammation and immunity. Mammals have four MLKs, mostly conserved in vertebrates, which contain an SH3 domain, a catalytic kinase domain, a leucine zipper, a proline-rich region, and a CRIB domain that mediates binding to GTP-bound Cdc42 and Rac. MLKs play roles in immunity and inflammation, as well as in cell death, proliferation, and cell cycle regulation.The MLK3 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

293-536 4.26e-40

Catalytic domain of the Protein Tyrosine Kinases, Apoptosis-associated tyrosine kinases; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. The Aatyk subfamily is also referred to as the lemur tyrosine kinase (Lmtk) subfamily. It consists of Aatyk1 (Lmtk1), Aatyk2 (Lmtk2, Brek), Aatyk3 (Lmtk3), and similar proteins. Aatyk proteins are mostly receptor PTKs (RTKs) containing a transmembrane segment and a long C-terminal cytoplasmic tail with a catalytic domain. Aatyk1 does not contain a transmembrane segment and is a cytoplasmic (or nonreceptor) kinase. Aatyk proteins are classified as PTKs based on overall sequence similarity and the phylogenetic tree. However, analysis of catalytic residues suggests that Aatyk proteins may be multispecific kinases, functioning also as serine/threonine kinases. They are involved in neural differentiation, nerve growth factor (NGF) signaling, apoptosis, and spermatogenesis. The Aatyk subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Transforming Growth Factor beta Activated Kinase-1; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. TAK1 is also known as mitogen-activated protein kinase kinase kinase 7 (MAPKKK7 or MAP3K7), TAK, or MEKK7. As a MAPKKK, it is an important mediator of cellular responses to extracellular signals. It regulates both the c-Jun N-terminal kinase and p38 MAPK cascades by activating the MAPK kinases, MKK4 and MKK3/6. In addition, TAK1 plays diverse roles in immunity and development, in different biological contexts, through many signaling pathways including TGFbeta/BMP, Wnt/Fz, and NF-kB. It is also implicated in the activation of the tumor suppressor kinase, LKB1. The TAK1 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine kinase, Receptor Interacting Protein; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. RIP kinases serve as essential sensors of cellular stress. They are involved in regulating NF-kappaB and MAPK signaling, and are implicated in mediating cellular processes such as apoptosis, necroptosis, differentiation, and survival. RIP kinases contain a homologous N-terminal kinase domain and varying C-terminal domains. Higher vertebrates contain multiple RIP kinases, with mammals harboring at least five members. RIP1 and RIP2 harbor C-terminal domains from the Death domain (DD) superfamily while RIP4 contains ankyrin (ANK) repeats. RIP3 contain a RIP homotypic interaction motif (RHIM) that facilitates binding to RIP1. RIP1 and RIP3 are important in apoptosis and necroptosis, while RIP2 and RIP4 play roles in keratinocyte differentiation and inflammatory immune responses. The RIP subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

291-486 1.59e-36

Catalytic domain of STE family Protein Kinases; PKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine (ST) or tyrosine residues on protein substrates. This family is composed of STKs, and some dual-specificity PKs that phosphorylate both threonine and tyrosine residues of target proteins. Most members are kinases involved in mitogen-activated protein kinase (MAPK) signaling cascades, acting as MAPK kinases (MAPKKs), MAPKK kinases (MAPKKKs), or MAPKKK kinases (MAP4Ks). The MAPK signaling pathways are important mediators of cellular responses to extracellular signals. The pathways involve a triple kinase core cascade comprising of the MAPK, which is phosphorylated and activated by a MAPKK, which itself is phosphorylated and activated by a MAPKKK. Each MAPK cascade is activated either by a small GTP-binding protein or by an adaptor protein, which transmits the signal either directly to a MAPKKK to start the triple kinase core cascade or indirectly through a mediator kinase, a MAP4K. Other STE family members include p21-activated kinases (PAKs) and class III myosins, among others. PAKs are Rho family GTPase-regulated kinases that serve as important mediators in the function of Cdc42 (cell division cycle 42) and Rac. Class III myosins are motor proteins containing an N-terminal kinase catalytic domain and a C-terminal actin-binding domain, which can phosphorylate several cytoskeletal proteins, conventional myosin regulatory light chains, as well as autophosphorylate the C-terminal motor domain. They play an important role in maintaining the structural integrity of photoreceptor cell microvilli. The STE family is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

301-532 1.70e-35

Pseudokinase domain of membrane Guanylate Cyclase receptors; The pseudokinase domain shows similarity to protein kinases but lacks crucial residues for catalytic activity. Membrane (or particulate) GCs consist of an extracellular ligand-binding domain, a single transmembrane region, and an intracellular tail that contains a PK-like domain, an amphiphatic region and a catalytic GC domain that catalyzes the conversion of GTP into cGMP and pyrophosphate. Membrane GCs act as receptors that transduce an extracellular signal to the intracellular production of cGMP, which has been implicated in many processes including cell proliferation, phototransduction, and muscle contractility, through its downstream effectors such as PKG. The PK-like domain of GCs lack a critical aspartate involved in ATP binding and does not exhibit kinase activity. It functions as a negative regulator of the catalytic GC domain and may also act as a docking site for interacting proteins such as GC-activating proteins. The GC subfamily is part of a larger superfamily that includes the catalytic domains of protein serine/threonine kinases, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-534 6.08e-35

Catalytic domain of the Serine/Threonine kinases, Interleukin-1 Receptor Associated Kinases and related STKs; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. IRAKs are involved in Toll-like receptor (TLR) and interleukin-1 (IL-1) signalling pathways, and are thus critical in regulating innate immune responses and inflammation. Some IRAKs may also play roles in T- and B-cell signaling, and adaptive immunity. Vertebrates contain four IRAKs (IRAK-1, -2, -3 (or -M), and -4) that display distinct functions and patterns of expression and subcellular distribution, and can differentially mediate TLR signaling. IRAK-1, -2, and -4 are ubiquitously expressed and are active kinases, while IRAK-M is only induced in monocytes and macrophages and is an inactive kinase. Variations in IRAK genes are linked to diverse diseases including infection, sepsis, cancer, and autoimmune diseases. IRAKs contain an N-terminal Death domain (DD), a proST region (rich in serines, prolines, and threonines), a central kinase domain (a pseudokinase domain in the case of IRAK3), and a C-terminal domain; IRAK-4 lacks the C-terminal domain. This subfamily includes plant receptor-like kinases (RLKs) including Arabidopsis thaliana BAK1 and CLAVATA1 (CLV1). BAK1 functions in BR (brassinosteroid)-regulated plant development and in pathways involved in plant resistance to pathogen infection and herbivore attack. CLV1, directly binds small signaling peptides, CLAVATA3 (CLV3) and CLAVATA3/EMBRYO SURROUNDING REGI0N (CLE), to restrict stem cell proliferation: the CLV3-CLV1-WUS (WUSCHEL) module influences stem cell maintenance in the shoot apical meristem, and the CLE40 (CLAVATA3/EMBRYO SURROUNDING REGION40) -ACR4 (CRINKLY4) -CLV1- WOX5 (WUSCHEL-RELATED HOMEOBOX5) module at the root apical meristem. The IRAK subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

292-502 1.85e-34

Catalytic domain of AMP-activated protein kinase-like Serine/Threonine Kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. The AMPK-like subfamily is composed of AMPK, MARK, BRSK, NUAK, MELK, SNRK, TSSK, and SIK, among others. LKB1 serves as a master upstream kinase that activates AMPK and most AMPK-like kinases. AMPK, also called SNF1 (sucrose non-fermenting1) in yeasts and SnRK1 (SNF1-related kinase1) in plants, is a heterotrimeric enzyme composed of a catalytic alpha subunit and two regulatory subunits, beta and gamma. It is a stress-activated kinase that serves as master regulator of glucose and lipid metabolism by monitoring carbon and energy supplies, via sensing the cell's AMP:ATP ratio. MARKs phosphorylate tau and related microtubule-associated proteins (MAPs), and regulates microtubule-based intracellular transport. They are involved in embryogenesis, epithelial cell polarization, cell signaling, and neuronal differentiation. BRSKs play important roles in establishing neuronal polarity. TSSK proteins are almost exclusively expressed postmeiotically in the testis and play important roles in spermatogenesis and/or spermiogenesis. The AMPK-like subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

289-508 2.96e-34

The catalytic domain of CAMK family Serine/Threonine Kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. CaMKs are multifunctional calcium and calmodulin (CaM) stimulated STKs involved in cell cycle regulation. There are several types of CaMKs including CaMKI, CaMKII, and CaMKIV. CaMKI proteins are monomeric and they play pivotal roles in the nervous system, including long-term potentiation, dendritic arborization, neurite outgrowth, and the formation of spines, synapses, and axons. CaMKII is a signaling molecule that translates upstream calcium and reactive oxygen species (ROS) signals into downstream responses that play important roles in synaptic function and cardiovascular physiology. CAMKIV is implicated in regulating several transcription factors like CREB, MEF2, and retinoid orphan receptors, as well as in T-cell development and signaling. The CAMK family also consists of other related kinases including the Phosphorylase kinase Gamma subunit (PhKG), the C-terminal kinase domains of Ribosomal S6 kinase (RSK) and Mitogen and stress-activated kinase (MSK), Doublecortin-like kinase (DCKL), and the MAPK-activated protein kinases MK2, MK3, and MK5, among others. The CAMK family is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

288-532 6.00e-34

Pseudokinase (repeat 1) domain of the Protein Tyrosine Kinases, Janus kinases; The Jak subfamily is composed of Jak1, Jak2, Jak3, TYK2, and similar proteins. They are cytoplasmic (or nonreceptor) PTKs containing an N-terminal FERM domain, followed by a Src homology 2 (SH2) domain, a pseudokinase domain, and a C-terminal catalytic tyr kinase domain. The pseudokinase domain shows similarity to tyr kinases but lacks crucial residues for catalytic activity and ATP binding. It modulates the kinase activity of the C-terminal catalytic domain. In the case of Jak2, the presumed pseudokinase (repeat 1) domain exhibits dual-specificity kinase activity, phosphorylating two negative regulatory sites in Jak2: Ser523 and Tyr570. Most Jaks are expressed in a wide variety of tissues, except for Jak3, which is expressed only in hematopoietic cells. Jaks are crucial for cytokine receptor signaling. They are activated by autophosphorylation upon cytokine-induced receptor aggregation, and subsequently trigger downstream signaling events such as the phosphorylation of signal transducers and activators of transcription (STATs). Jaks are also involved in regulating the surface expression of some cytokine receptors. The Jak-STAT pathway is involved in many biological processes including hematopoiesis, immunoregulation, host defense, fertility, lactation, growth, and embryogenesis. The Jak subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-539 6.03e-33

Catalytic domain of the Serine/Threonine kinase, Receptor Interacting Protein 1; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. RIP1 harbors a C-terminal Death domain (DD), which binds death receptors (DRs) including TNF receptor 1, Fas, TNF-related apoptosis-inducing ligand receptor 1 (TRAILR1), and TRAILR2. It also interacts with other DD-containing adaptor proteins such as TRADD and FADD. RIP1 can also recruit other kinases including MEKK1, MEKK3, and RIP3 through an intermediate domain (ID) that bears a RIP homotypic interaction motif (RHIM). RIP1 plays a crucial role in determining a cell's fate, between survival or death, following exposure to stress signals. It is important in the signaling of NF-kappaB and MAPKs, and it links DR-associated signaling to reactive oxygen species (ROS) production. Abnormal RIP1 function may result in ROS accummulation affecting inflammatory responses, innate immunity, stress responses, and cell survival. RIP kinases serve as essential sensors of cellular stress. The RIP1 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, LIM domain kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. LIMKs phosphorylate and inactivate cofilin, an actin depolymerizing factor, to induce the reorganization of the actin cytoskeleton. They act downstream of Rho GTPases and are expressed ubiquitously. As regulators of actin dynamics, they contribute to diverse cellular functions such as cell motility, morphogenesis, differentiation, apoptosis, meiosis, mitosis, and neurite extension. LIMKs contain the LIM (two repeats), PDZ, and catalytic kinase domains. Vertebrate have two members, LIMK1 and LIMK2. The LIMK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

292-537 5.14e-32

Catalytic domain of the Protein Tyrosine Kinase, Apoptosis-associated tyrosine kinase 2; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Aatyk2 is a member of the Aatyk subfamily of proteins, which are receptor kinases containing a transmembrane segment and a long C-terminal cytoplasmic tail with a catalytic domain. Aatyk2 is also called lemur tyrosine kinase 2 (Lmtk2) or brain-enriched kinase (Brek). It is expressed at high levels in early postnatal brain, and has been shown to play a role in nerve growth factor (NGF) signaling. Studies with knockout mice reveal that Aatyk2 is essential for late stage spermatogenesis. Although it is classified as a PTK based on sequence similarity and the phylogenetic tree, Aatyk2 has been functionally characterized as a serine/threonine kinase. The Aatyk2 subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, B-Raf (Rapidly Accelerated Fibrosarcoma) kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. B-Raf activates ERK with the strongest magnitude, compared with other Raf kinases. Mice embryos deficient in B-Raf die around midgestation due to vascular hemorrhage caused by apoptotic endothelial cells. Mutations in B-Raf have been implicated in initiating tumorigenesis and tumor progression, and are found in malignant cutaneous melanoma, papillary thyroid cancer, as well as in ovarian and colorectal carcinomas. Most oncogenic B-Raf mutations are located at the activation loop of the kinase and surrounding regions; the V600E mutation accounts for around 90% of oncogenic mutations. The V600E mutant constitutively activates MEK, resulting in sustained activation of ERK. B-Raf is a mitogen-activated protein kinase kinase kinase (MAP3K, MKKK, MAPKKK), which phosphorylates and activates MAPK kinases (MAPKKs or MKKs or MAP2Ks), which in turn phosphorylate and activate MAPKs during signaling cascades that are important in mediating cellular responses to extracellular signals. They function in the linear Ras-Raf-MEK-ERK pathway that regulates many cellular processes including cycle regulation, proliferation, differentiation, survival, and apoptosis. The B-Raf subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinases, Raf (Rapidly Accelerated Fibrosarcoma) kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Raf kinases act as mitogen-activated protein kinase kinase kinases (MAP3Ks, MKKKs, MAPKKKs), which phosphorylate and activate MAPK kinases (MAPKKs or MKKs or MAP2Ks), which in turn phosphorylate and activate MAPKs during signaling cascades that are important in mediating cellular responses to extracellular signals. They function in the linear Ras-Raf-MEK-ERK pathway that regulates many cellular processes including cycle regulation, proliferation, differentiation, survival, and apoptosis. Aberrant expression or activation of components in this pathway are associated with tumor initiation, progression, and metastasis. Raf proteins contain a Ras binding domain, a zinc finger cysteine-rich domain, and a catalytic kinase domain. Vertebrates have three Raf isoforms (A-, B-, and C-Raf) with different expression profiles, modes of regulation, and abilities to function in the ERK cascade, depending on cellular context and stimuli. They have essential and non-overlapping roles during embryo- and organogenesis. Knockout of each isoform results in a lethal phenotype or abnormality in most mouse strains. The Raf subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

287-534 2.06e-31

Catalytic domain of the Serine/Threonine kinase, Aurora kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Aurora kinases are key regulators of mitosis and are essential for the accurate and equal division of genomic material from parent to daughter cells. Yeast contains only one Aurora kinase while most higher eukaryotes have two. Vertebrates contain at least 2 Aurora kinases (A and B); mammals contains a third Aurora kinase gene (C). Aurora-A regulates cell cycle events from the late S-phase through the M-phase including centrosome maturation, mitotic entry, centrosome separation, spindle assembly, chromosome alignment, cytokinesis, and mitotic exit. Aurora-A activation depends on its autophosphorylation and binding to the microtubule-associated protein TPX2. Aurora-B is most active at the transition during metaphase to the end of mitosis. It is critical for accurate chromosomal segregation, cytokinesis, protein localization to the centrosome and kinetochore, correct microtubule-kinetochore attachments, and regulation of the mitotic checkpoint. Aurora-C is mainly expressed in meiotically dividing cells; it was originally discovered in mice as a testis-specific STK called Aie1. Both Aurora-B and -C are chromosomal passenger proteins that can form complexes with INCENP and survivin, and they may have redundant cellular functions. The Aurora subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of Cell division control protein 7-like Serine/Threonine Kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Members of this subfamily include Schizosaccharomyces pombe Cdc7, Saccharomyces cerevisiae Cdc15, Arabidopsis thaliana mitogen-activated protein kinase kinase kinase (MAPKKK) epsilon, and related proteins. MAPKKKs phosphorylate and activate MAPK kinases, which in turn phosphorylate and activate MAPKs during signaling cascades that are important in mediating cellular responses to extracellular signals. Fission yeast Cdc7 is essential for cell division by playing a key role in the initiation of septum formation and cytokinesis. Budding yeast Cdc15 functions to coordinate mitotic exit with cytokinesis. Arabidopsis MAPKKK epsilon is required for pollen development in the plasma membrane. The Cdc7-like subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-529 1.48e-30

Catalytic domain of AGC family Serine/Threonine Kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. AGC kinases regulate many cellular processes including division, growth, survival, metabolism, motility, and differentiation. Many are implicated in the development of various human diseases. Members of this family include cAMP-dependent Protein Kinase (PKA), cGMP-dependent Protein Kinase (PKG), Protein Kinase C (PKC), Protein Kinase B (PKB), G protein-coupled Receptor Kinase (GRK), Serum- and Glucocorticoid-induced Kinase (SGK), and 70 kDa ribosomal Protein S6 Kinase (p70S6K or S6K), among others. AGC kinases share an activation mechanism based on the phosphorylation of up to three sites: the activation loop (A-loop), the hydrophobic motif (HM) and the turn motif. Phosphorylation at the A-loop is required of most AGC kinases, which results in a disorder-to-order transition of the A-loop. The ordered conformation results in the access of substrates and ATP to the active site. A subset of AGC kinases with C-terminal extensions containing the HM also requires phosphorylation at this site. Phosphorylation at the HM allows the C-terminal extension to form an ordered structure that packs into the hydrophobic pocket of the catalytic domain, which then reconfigures the kinase into an active bi-lobed state. In addition, growth factor-activated AGC kinases such as PKB, p70S6K, RSK, MSK, PKC, and SGK, require phosphorylation at the turn motif (also called tail or zipper site), located N-terminal to the HM at the C-terminal extension. The AGC family is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and Phosphoinositide 3-Kinase.

287-542 5.65e-30

Catalytic domain of the Serine/Threonine Kinase, A-Raf (Rapidly Accelerated Fibrosarcoma) kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. A-Raf cooperates with C-Raf in regulating ERK transient phosphorylation that is associated with cyclin D expression and cell cycle progression. Mice deficient in A-Raf are born alive but show neurological and intestinal defects. A-Raf demonstrates low kinase activity to MEK, compared with B- and C-Raf, and may also have alternative functions other than in the ERK signaling cascade. It regulates the M2 type pyruvate kinase, a key glycolytic enzyme. It also plays a role in endocytic membrane trafficking. A-Raf is a mitogen-activated protein kinase kinase kinase (MAP3K, MKKK, MAPKKK), which phosphorylates and activates MAPK kinases (MAPKKs or MKKs or MAP2Ks), which in turn phosphorylate and activate MAPKs during signaling cascades that are important in mediating cellular responses to extracellular signals. It functions in the linear Ras-Raf-MEK-ERK pathway that regulates many cellular processes including cycle regulation, proliferation, differentiation, survival, and apoptosis. The A-Raf subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of Male germ cell-Associated Kinase-like Serine/Threonine Kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. This subfamily is composed of human MAK and MAK-related kinase (MRK), Saccharomyces cerevisiae Ime2p, Schizosaccharomyces pombe Mei4-dependent protein 3 (Mde3) and Pit1, Caenorhabditis elegans dyf-5, Arabidopsis thaliana MHK, and similar proteins. These proteins play important roles during meiosis. MAK is highly expressed in testicular cells specifically in the meiotic phase, but is not essential for spermatogenesis and fertility. It functions as a coactivator of the androgen receptor in prostate cells. MRK, also called Intestinal Cell Kinase (ICK), is expressed ubiquitously, with highest expression in the ovary and uterus. A missense mutation in MRK causes endocrine-cerebro-osteodysplasia, suggesting that this protein plays an important role in the development of many organs. MAK and MRK may be involved in regulating cell cycle and cell fate. Ime2p is a meiosis-specific kinase that is important during meiotic initiation and during the later stages of meiosis. Mde3 functions downstream of the transcription factor Mei-4 which is essential for meiotic prophase I. The MAK-like subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of Mammalian Ste20-like protein kinase 3-like Serine/Threonine Kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. This subfamily is composed of MST3, MST4, STK25, Schizosaccharomyces pombe Nak1 and Sid1, Saccharomyces cerevisiae sporulation-specific protein 1 (SPS1), and related proteins. Nak1 is required by fission yeast for polarizing the tips of actin cytoskeleton and is involved in cell growth, cell separation, cell morphology and cell-cycle progression. Sid1 is a component in the septation initiation network (SIN) signaling pathway, and plays a role in cytokinesis. SPS1 plays a role in regulating proteins required for spore wall formation. MST4 plays a role in mitogen-activated protein kinase (MAPK) signaling during cytoskeletal rearrangement, morphogenesis, and apoptosis. MST3 phosphorylates the STK NDR and may play a role in cell cycle progression and cell morphology. STK25 may play a role in the regulation of cell migration and polarization. The MST3-like subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine kinases, Autophagy-related protein 1 and Unc-51-like kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. This subfamily includes yeast ATG1 and metazoan homologs including vertebrate ULK1-3. The ATG1/ULK complex is conserved from yeast to humans and it plays a critical role in the initiation of autophagy, the intracellular system that leads to the lysosomal degradation of cellular components and their recycling into basic metabolic units. It is involved in nutrient sensing and signaling, the assembly of autophagy factors and the execution of autophagy. In metazoans, ATG1 homologs display additional functions. Unc-51 and ULKs have been implicated in neuronal and axonal development. The ATG1/ULK subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-542 1.67e-29

Catalytic domain of the Serine/Threonine Kinase, LIM domain kinase 2; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. LIMK2 activation is induced by transforming growth factor-beta l (TGFb-l) and shares the same subcellular location as the cofilin family member twinfilin, which may be its biological substrate. LIMK2 plays a role in spermatogenesis, and may contribute to tumor progression and metastasis formation in some cancer cells. LIMKs phosphorylate and inactivate cofilin, an actin depolymerizing factor, to induce the reorganization of the actin cytoskeleton. They act downstream of Rho GTPases and are expressed ubiquitously. As regulators of actin dynamics, they contribute to diverse cellular functions such as cell motility, morphogenesis, differentiation, apoptosis, meiosis, mitosis, and neurite extension. LIMKs contain the LIM (two repeats), PDZ, and catalytic kinase domains. The LIMK2 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Never In Mitosis gene A (NIMA)-related kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. The Nek family is composed of 11 different mammalian members (Nek1-11) with similarity to the catalytic domain of Aspergillus nidulans NIMA kinase, the founding member of the Nek family, which was identified in a screen for cell cycle mutants that were prevented from entering mitosis. Neks contain a conserved N-terminal catalytic domain and a more divergent C-terminal regulatory region of various sizes and structures. They are involved in the regulation of downstream processes following the activation of Cdc2, and many of their functions are cell cycle-related. They play critical roles in microtubule dynamics during ciliogenesis and mitosis. The Nek family is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-542 2.20e-29

Catalytic domain of the Serine/Threonine Kinase, LIM domain kinase 1; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. LIMK1 activation is induced by bone morphogenic protein, vascular endothelial growth factor, and thrombin. It plays roles in microtubule disassembly and cell cycle progression, and is critical in the regulation of neurite outgrowth. LIMK1 knockout mice show abnormalities in dendritic spine morphology and synaptic function. LIMK1 is one of the genes deleted in patients with Williams Syndrome, which is characterized by distinct craniofacial features, cardiovascular problems, as well as behavioral and neurological abnormalities. LIMKs phosphorylate and inactivate cofilin, an actin depolymerizing factor, to induce the reorganization of the actin cytoskeleton. They act downstream of Rho GTPases and are expressed ubiquitously. As regulators of actin dynamics, they contribute to diverse cellular functions such as cell motility, morphogenesis, differentiation, apoptosis, meiosis, mitosis, and neurite extension. LIMKs contain the LIM (two repeats), PDZ, and catalytic kinase domains. The LIMK1 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

281-537 2.96e-29

Catalytic domain of Brain-specific serine/threonine-protein kinases 1 and 2; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. BRSK1, also called SAD-B or SAD1 (Synapses of Amphids Defective homolog 1), and BRSK2, also called SAD-A, are highly expressed in mammalian forebrain. They play important roles in establishing neuronal polarity. BRSK1/2 double knock-out mice die soon after birth, showing thin cerebral cortices due to disordered subplate layers and neurons that lack distinct axons and dendrites. BRSK1 regulates presynaptic neurotransmitter release. Its activity fluctuates during cell cysle progression and it acts as a regulator of centrosome duplication. BRSK2 is also abundant in pancreatic islets, where it is involved in the regulation of glucose-stimulated insulin secretion. The BRSK1/2 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

287-534 1.88e-28

Catalytic domain of Plant dual-specificity Mitogen-Activated Protein Kinase Kinases and similar proteins; PKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine (ST) or tyrosine residues on protein substrates. Members of this group include MAPKKs from plants, kinetoplastids, alveolates, and mycetozoa. The MAPKK, LmxPK4, from Leishmania mexicana, is important in differentiation and virulence. Dictyostelium discoideum MEK1 is required for proper chemotaxis; MEK1 null mutants display severe defects in cell polarization and directional movement. Plants contain multiple MAPKKs like other eukaryotes. The Arabidopsis genome encodes for 10 MAPKKs while poplar and rice contain 13 MAPKKs each. The functions of these proteins have not been fully elucidated. There is evidence to suggest that MAPK cascades are involved in plant stress responses. In Arabidopsis, MKK3 plays a role in pathogen signaling; MKK2 is involved in cold and salt stress signaling; MKK4/MKK5 participates in innate immunity; and MKK7 regulates basal and systemic acquired resistance. The MAPKK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine kinases, Liver Kinase B1, Calmodulin Dependent Protein Kinase Kinase, and similar proteins; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Both LKB1 and CaMKKs can phosphorylate and activate AMP-activated protein kinase (AMPK). LKB1, also called STK11, serves as a master upstream kinase that activates AMPK and most AMPK-like kinases. LKB1 and AMPK are part of an energy-sensing pathway that links cell energy to metabolism and cell growth. They play critical roles in the establishment and maintenance of cell polarity, cell proliferation, cytoskeletal organization, as well as T-cell metabolism, including T-cell development, homeostasis, and effector function. CaMKKs are upstream kinases of the CaM kinase cascade that phosphorylate and activate CaMKI and CamKIV. They may also phosphorylate other substrates including PKB and AMPK. Vertebrates contain two CaMKKs, CaMKK1 (or alpha) and CaMKK2 (or beta). CaMKK1 is involved in the regulation of glucose uptake in skeletal muscles. CaMKK2 is involved in regulating energy balance, glucose metabolism, adiposity, hematopoiesis, inflammation, and cancer. The LKB1/CaMKK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

281-544 2.10e-28

Catalytic domain of the Serine/Threonine Kinase, C-Raf (Rapidly Accelerated Fibrosarcoma) kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. C-Raf, also known as Raf-1 or c-Raf-1, is ubiquitously expressed and was the first Raf identified. It was characterized as the acquired oncogene from an acutely transforming murine sarcoma virus (3611-MSV) and the transforming agent from the avian retrovirus MH2. C-Raf-deficient mice embryos die around midgestation with increased apoptosis of embryonic tissues, especially in the fetal liver. One of the main functions of C-Raf is restricting caspase activation to promote survival in response to specific stimuli such as Fas stimulation, macrophage apoptosis, and erythroid differentiation. C-Raf is a mitogen-activated protein kinase kinase kinase (MAP3K, MKKK, MAPKKK), which phosphorylates and activates MAPK kinases (MAPKKs or MKKs or MAP2Ks), which in turn phosphorylate and activate MAPKs during signaling cascades that are important in mediating cellular responses to extracellular signals. It functions in the linear Ras-Raf-MEK-ERK pathway that regulates many cellular processes including cycle regulation, proliferation, differentiation, survival, and apoptosis. The C-Raf subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

292-539 2.13e-28

Catalytic domain of Cyclin-Dependent protein Kinase Like Serine/Threonine Kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. This subfamily is composed of CDKL1-5 and similar proteins. Some CDKLs, like CDKL1 and CDKL3, may be implicated in transformation and others, like CDKL3 and CDKL5, are associated with mental retardation when impaired. CDKL2 plays a role in learning and memory. CDKs belong to a large family of STKs that are regulated by their cognate cyclins. Together, they are involved in the control of cell-cycle progression, transcription, and neuronal function. The CDKL subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

289-503 2.80e-28

Catalytic domain of testis-specific serine/threonine kinases and similar proteins; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. TSSK proteins are almost exclusively expressed postmeiotically in the testis and play important roles in spermatogenesis and/or spermiogenesis. There are five mammalian TSSK proteins which show differences in their localization and timing of expression. TSSK1 and TSSK2 are expressed specifically in meiotic and postmeiotic spermatogenic cells, respectively. TSSK3 has been reported to be expressed in the interstitial Leydig cells of adult testis. TSSK4, also called TSSK5, is expressed in testis from haploid round spermatids to mature spermatozoa. TSSK6, also called SSTK, is expressed at the head of elongated sperm. TSSK1/TSSK2 double knock-out and TSSK6 null mice are sterile without manifesting other defects, making these kinases viable targets for male contraception. The TSSK-like subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-542 2.87e-28

Catalytic domain of an unknown subfamily of LIM domain kinase-like protein kinases; PKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine or tyrosine residues on protein substrates. This group is composed of uncharacterized proteins with similarity to LIMK and Testicular or testis-specific protein kinase (TESK). LIMKs are characterized as serine/threonine kinases (STKs) while TESKs are dual-specificity protein kinases. Both LIMK and TESK phosphorylate and inactivate cofilin, an actin depolymerizing factor, to induce the reorganization of the actin cytoskeleton. They are implicated in many cellular functions including cell spreading, motility, morphogenesis, meiosis, mitosis, and spermatogenesis. The LIMK-like subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Dual-specificity protein kinase, TNNI3-interacting kinase; Dual-specificity PKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine as well as tyrosine residues on protein substrates. TNNI3K, also called cardiac ankyrin repeat kinase (CARK), is a cardiac-specific troponin I-interacting kinase that promotes cardiac myogenesis, improves cardiac performance, and protects the myocardium from ischemic injury. It contains N-terminal ankyrin repeats, a catalytic kinase domain, and a C-terminal serine-rich domain. TNNI3K exerts a disease-accelerating effect on cardiac dysfunction and reduced survival in mouse models of cardiomyopathy. The TNNI3K subfamily is part of a larger superfamily that includes the catalytic domains of other protein serine/threonine PKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

287-542 3.77e-28

Pseudokinase domain of Kinase Suppressor of Ras; The pseudokinase domain shows similarity to protein kinases but lacks crucial residues for catalytic activity. KSR is a scaffold protein that functions downstream of Ras and upstream of Raf in the Extracellular signal-Regulated Kinase (ERK) pathway that regulates many cellular processes including cycle regulation, proliferation, differentiation, survival, and apoptosis. KSR proteins regulate the assembly and activation of the Raf/MEK/ERK module upon Ras activation at the membrane by direct association of its components. They are widely regarded as pseudokinases, but there is some debate in this designation as a few groups have reported detecting kinase catalytic activity for KSRs, specifically KSR1. Vertebrates contain two KSR proteins, KSR1 and KSR2. The KSR subfamily is part of a larger superfamily that includes the catalytic domains of other protein kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

314-532 5.08e-28

Pseudokinase domain of the membrane Guanylate Cyclase receptors, GC-A and GC-B; The pseudokinase domain shows similarity to protein kinases but lacks crucial residues for catalytic activity and/or ATP binding. GC-A binds and is activated by the atrial and B-type natriuretic peptides, ANP and BNP, which are important in blood pressure regulation and cardiac pathophysiology. GC-B binds the C-type natriuretic peptide, CNP, which is a potent vasorelaxant and functions in vascular remodeling and bone growth regulation. Membrane (or particulate) GCs consist of an extracellular ligand-binding domain, a single transmembrane region, and an intracellular tail that contains a PK-like domain, an amphiphatic region and a catalytic GC domain that catalyzes the conversion of GTP into cGMP and pyrophosphate. Membrane GCs act as receptors that transduce an extracellular signal to the intracellular production of cGMP, which has been implicated in many processes including cell proliferation, phototransduction, and muscle contractility, through its downstream effectors such as PKG. The PK-like domain of GCs functions as a negative regulator of the catalytic GC domain and may also act as a docking site for interacting proteins such as GC-activating proteins. The GC-A/B subfamily is part of a larger superfamily that includes the catalytic domains of protein serine/threonine kinases, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

292-534 1.03e-27

Catalytic domain of the Serine/Threonine Kinase, p21-activated kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. PAKs are Rho family GTPase-regulated kinases that serve as important mediators in the function of Cdc42 (cell division cycle 42) and Rac. PAKs are implicated in the regulation of many cellular processes including growth factor receptor-mediated proliferation, cell polarity, cell motility, cell death and survival, and actin cytoskeleton organization. PAK deregulation is associated with tumor development. PAKs from higher eukaryotes are classified into two groups (I and II), according to their biochemical and structural features. Group I PAKs contain a PBD (p21-binding domain) overlapping with an AID (autoinhibitory domain), a C-terminal catalytic domain, SH3 binding sites and a non-classical SH3 binding site for PIX (PAK-interacting exchange factor). Group II PAKs contain a PBD and a catalytic domain, but lack other motifs found in group I PAKs. Since group II PAKs do not contain an obvious AID, they may be regulated differently from group I PAKs. Group I PAKs interact with the SH3 containing proteins Nck, Grb2 and PIX; no such binding has been demonstrated for group II PAKs. The PAK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Protein Serine/Threonine Kinase, Never In Mitosis gene A (NIMA)-related kinase 11; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Nek11 is involved, through direct phosphorylation, in regulating the degradation of Cdc25A (Cell Division Cycle 25 homolog A), which plays a role in cell cycle progression and in activating cyclin dependent kinases. Nek11 is activated by CHK1 (CHeckpoint Kinase 1) and may be involved in the G2/M checkpoint. Nek11 may also play a role in the S-phase checkpoint as well as in DNA replication and genotoxic stress responses. It is one in a family of 11 different Neks (Nek1-11) that are involved in cell cycle control. The Nek family is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

111-164 1.18e-27

Src homology 3 domain of the Protein Tyrosine Kinase, Abelson kinase; Abl (or c-Abl) is a ubiquitously-expressed cytoplasmic (or nonreceptor) PTK that contains SH3, SH2, and tyr kinase domains in its N-terminal region, as well as nuclear localization motifs, a putative DNA-binding domain, and F- and G-actin binding domains in its C-terminal tail. It also contains a short autoinhibitory cap region in its N-terminus. Abl function depends on its subcellular localization. In the cytoplasm, Abl plays a role in cell proliferation and survival. In response to DNA damage or oxidative stress, Abl is transported to the nucleus where it induces apoptosis. In chronic myelogenous leukemia (CML) patients, an aberrant translocation results in the replacement of the first exon of Abl with the BCR (breakpoint cluster region) gene. The resulting BCR-Abl fusion protein is constitutively active and associates into tetramers, resulting in a hyperactive kinase sending a continuous signal. This leads to uncontrolled proliferation, morphological transformation and anti-apoptotic effects. BCR-Abl is the target of selective inhibitors, such as imatinib (Gleevec), used in the treatment of CML. Abl2, also known as ARG (Abelson-related gene), is thought to play a cooperative role with Abl in the proper development of the nervous system. The Tel-ARG fusion protein, resulting from reciprocal translocation between chromosomes 1 and 12, is associated with acute myeloid leukemia (AML). SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.

293-480 1.36e-27

Catalytic domain of Cyclin-Dependent protein Kinase-like Serine/Threonine Kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. CDKs belong to a large family of STKs that are regulated by their cognate cyclins. Together, they are involved in the control of cell-cycle progression, transcription, and neuronal function. CDKs are partly regulated by their subcellular localization, which defines substrate phosphorylation and the resulting specific function. CDK1, CDK2, CDK4, and CDK6 have well-defined functions in the cell cycle, such as the regulation of the early G1 phase by CDK4 or CDK6, the G1/S phase transition by CDK2, or the entry of mitosis by CDK1. They also exhibit overlapping cyclin specificity and functions in certain conditions. Knockout mice with a single CDK deleted remain viable with specific phenotypes, showing that some CDKs can compensate for each other. For example, CDK4 can compensate for the loss of CDK6, however, double knockout mice with both CDK4 and CDK6 deleted die in utero. CDK8 and CDK9 are mainly involved in transcription while CDK5 is implicated in neuronal function. CDK7 plays essential roles in both the cell cycle as a CDK-Activating Kinase (CAK) and in transcription as a component of the general transcription factor TFIIH. The CDK-like subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

293-489 1.75e-27

Catalytic domain of the Serine/Threonine Kinases, Mammalian STe20-like protein kinase 1 and 2; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. This subfamily is composed of MST1, MST2, and related proteins including Drosophila Hippo and Dictyostelium discoideum Krs1 (kinase responsive to stress 1). MST1/2 and Hippo are involved in a conserved pathway that governs cell contact inhibition, organ size control, and tumor development. MST1 activates the mitogen-activated protein kinases (MAPKs) p38 and c-Jun N-terminal kinase (JNK) through MKK7 and MEKK1 by acting as a MAPK kinase kinase kinase. Activation of JNK by MST1 leads to caspase activation and apoptosis. MST1 has also been implicated in cell proliferation and differentiation. Krs1 may regulate cell growth arrest and apoptosis in response to cellular stress. The MST1/2 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Never In Mitosis gene A (NIMA)-related kinase 6; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Nek6 is required for the transition from metaphase to anaphase. It also plays important roles in mitotic spindle formation and cytokinesis. Activated by Nek9 during mitosis, Nek6 phosphorylates Eg5, a kinesin that is important for spindle bipolarity. Nek6 localizes to spindle microtubules during metaphase and anaphase, and to the midbody during cytokinesis. It is one in a family of 11 different Neks (Nek1-11) that are involved in cell cycle control. The Nek family is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of CMGC family Serine/Threonine Kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. The CMGC family consists of Cyclin-Dependent protein Kinases (CDKs), Mitogen-activated protein kinases (MAPKs) such as Extracellular signal-regulated kinase (ERKs), c-Jun N-terminal kinases (JNKs), and p38, and other kinases. CDKs belong to a large subfamily of STKs that are regulated by their cognate cyclins. Together, they are involved in the control of cell-cycle progression, transcription, and neuronal function. MAPKs serve as important mediators of cellular responses to extracellular signals. They control critical cellular functions including differentiation, proliferation, migration, and apoptosis. They are also implicated in the pathogenesis of many diseases including multiple types of cancer, stroke, diabetes, and chronic inflammation. Other members of the CMGC family include casein kinase 2 (CK2), Dual-specificity tYrosine-phosphorylated and -Regulated Kinase (DYRK), Glycogen Synthase Kinase 3 (GSK3), among many others. The CMGC family is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

293-534 6.07e-27

Catalytic domain of the Serine/Threonine Kinases, Oxidative stress response kinase and Ste20-related proline alanine-rich kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. SPAK is also referred to as STK39 or PASK (proline-alanine-rich STE20-related kinase). OSR1 and SPAK regulate the activity of cation-chloride cotransporters through direct interaction and phosphorylation. They are also implicated in cytoskeletal rearrangement, cell differentiation, transformation and proliferation. OSR1 and SPAK contain a conserved C-terminal (CCT) domain, which recognizes a unique motif ([RK]FX[VI]) present in their activating kinases (WNK1/WNK4) and their substrates. The OSR1 and SPAK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

287-534 1.75e-26

Catalytic domain of the dual-specificity Protein Kinase, Mitogen-Activated Protein Kinase Kinase; PKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine (ST) or tyrosine residues on protein substrates. MAPKKs are dual-specificity PKs that phosphorylate their downstream targets, MAPKs, at specific threonine and tyrosine residues. The MAPK signaling pathways are important mediators of cellular responses to extracellular signals. The pathways involve a triple kinase core cascade comprising the MAPK, which is phosphorylated and activated by a MAPK kinase (MAPKK or MKK or MAP2K), which itself is phosphorylated and activated by a MAPKK kinase (MAPKKK or MKKK or MAP3K). There are three MAPK subfamilies: extracellular signal-regulated kinase (ERK), c-Jun N-terminal kinase (JNK), and p38. In mammalian cells, there are seven MAPKKs (named MKK1-7) and 20 MAPKKKs. Each MAPK subfamily can be activated by at least two cognate MAPKKs and by multiple MAPKKKs. The MAPKK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

328-531 5.75e-26

Catalytic domain of the Serine/Threonine kinase, Leucine-Rich Repeat Kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. LRRKs are also classified as ROCO proteins because they contain a ROC (Ras of complex proteins)/GTPase domain followed by a COR (C-terminal of ROC) domain of unknown function. In addition, LRRKs contain a catalytic kinase domain and protein-protein interaction motifs including a WD40 domain, LRRs and ankyrin (ANK) repeats. LRRKs possess both GTPase and kinase activities, with the ROC domain acting as a molecular switch for the kinase domain, cycling between a GTP-bound state which drives kinase activity and a GDP-bound state which decreases the activity. Vertebrates contain two members, LRRK1 and LRRK2, which show complementary expression in the brain. Mutations in LRRK2 are linked to both familial and sporadic forms of Parkinson's disease. The normal roles of LRRKs are not clearly defined. They may be involved in mitogen-activated protein kinase (MAPK) pathways, protein translation control, programmed cell death pathways, and cytoskeletal dynamics. The LRRK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine kinase, Interleukin-1 Receptor Associated Kinase 4; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. IRAKs are involved in Toll-like receptor (TLR) and interleukin-1 (IL-1) signalling pathways, and are thus critical in regulating innate immune responses and inflammation. IRAKs contain an N-terminal Death domain (DD), a proST region (rich in serines, prolines, and threonines), a central kinase domain, and a C-terminal domain; IRAK-4 lacks the C-terminal domain. Vertebrates contain four IRAKs (IRAK-1, -2, -3 (or -M), and -4) that display distinct functions and patterns of expression and subcellular distribution, and can differentially mediate TLR signaling. IRAK4 plays a critical role in NFkB activation by its interaction with MyD88, which acts as a scaffold that enables IRAK4 to phosphorylate and activate IRAK1 and/or IRAK2. It also plays an important role in type I IFN production induced by TLR7/8/9. The IRAK4 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

292-486 1.50e-25

Catalytic domain of Serine/Threonine Kinase 36; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. STK36, also called Fused (or Fu) kinase, is involved in the Hedgehog signaling pathway. It is activated by the Smoothened (SMO) signal transducer, resulting in the stabilization of GLI transcription factors and the phosphorylation of SUFU to facilitate the nuclear accumulation of GLI. In Drosophila, Fused kinase is maternally required for proper segmentation during embryonic development and for the development of legs and wings during the larval stage. In mice, STK36 is not necessary for embryonic development, although mice deficient in STK36 display growth retardation postnatally. The STK36 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of Ste20-Like Kinase-like Serine/Threonine Kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Members of the subfamily include SLK, STK10 (also called LOK for Lymphocyte-Oriented Kinase), SmSLK (Schistosoma mansoni SLK), and related proteins. SLK promotes apoptosis through apoptosis signal-regulating kinase 1 (ASK1) and the mitogen-activated protein kinase (MAPK) p38. It also plays a role in mediating actin reorganization. STK10 is responsible in regulating the CD28 responsive element in T cells, as well as leukocyte function associated antigen (LFA-1)-mediated lymphocyte adhesion. SmSLK is capable of activating the MAPK Jun N-terminal kinase (JNK) pathway in human embryonic kidney cells as well as in Xenopus oocytes. It may participate in regulating MAPK cascades during host-parasite interactions. The SLK-like subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of Fungal Nak1-like Serine/Threonine Kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. This subfamily is composed of Schizosaccharomyces pombe Nak1, Saccharomyces cerevisiae Kic1p (kinase that interacts with Cdc31p) and related proteins. Nak1 (also called N-rich kinase 1), is required by fission yeast for polarizing the tips of actin cytoskeleton and is involved in cell growth, cell separation, cell morphology and cell-cycle progression. Kic1p is required by budding yeast for cell integrity and morphogenesis. Kic1p interacts with Cdc31p, the yeast homologue of centrin, and phosphorylates substrates in a Cdc31p-dependent manner. The Nak1 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Pseudokinase domain of the unknown subfamily of membrane Guanylate Cyclase receptors; The pseudokinase domain shows similarity to protein kinases but lacks crucial residues for catalytic activity. Membrane (or particulate) GCs consist of an extracellular ligand-binding domain, a single transmembrane region, and an intracellular tail that contains a PK-like domain, an amphiphatic region and a catalytic GC domain that catalyzes the conversion of GTP into cGMP and pyrophosphate. Membrane GCs act as receptors that transduce an extracellular signal to the intracellular production of cGMP, which has been implicated in many processes including cell proliferation, phototransduction, and muscle contractility, through its downstream effectors such as PKG. The PK-like domain of GCs lack a critical aspartate involved in ATP binding and does not exhibit kinase activity. It functions as a negative regulator of the catalytic GC domain and may also act as a docking site for interacting proteins such as GC-activating proteins. The GC subfamily is part of a larger superfamily that includes the catalytic domains of protein serine/threonine kinases, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

280-496 3.30e-25

Catalytic domain of the Serine/Threonine kinase, Unc-51-like kinase 1; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. The ATG1/ULK complex is conserved from yeast to humans and it plays a critical role in the initiation of autophagy, the intracellular system that leads to the lysosomal degradation of cellular components and their recycling into basic metabolic units. ULK1 is required for efficient amino acid starvation-induced autophagy and mitochondrial clearance. It associates with three autophagy-related proteins (Atg13, FIP200 amd Atg101) to form the ULK1 complex. All fours proteins are essential for autophagosome formation. ULK1 is regulated by both mammalian target-of rapamycin complex 1 (mTORC1) and AMP-activated protein kinase (AMPK). mTORC1 negatively regulates the ULK1 complex in a nutrient-dependent manner while AMPK stimulates autophagy by inhibiting mTORC1. ULK1 also plays neuron-specific roles and is involved in non-clathrin-coated endocytosis in growth cones, filopodia extension, neurite extension, and axon branching. The ULK1 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

292-529 4.19e-25

Catalytic domain of the Serine/Threonine Kinase, novel (nua) kinase family NUAK; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. NUAK proteins are classified as AMP-activated protein kinase (AMPK)-related kinases, which like AMPK are activated by the major tumor suppressor LKB1. Vertebrates contain two NUAK proteins, called NUAK1 and NUAK2. NUAK1, also called ARK5 (AMPK-related protein kinase 5), regulates cell proliferation and displays tumor suppression through direct interaction and phosphorylation of p53. It is also involved in cell senescence and motility. High NUAK1 expression is associated with invasiveness of nonsmall cell lung cancer (NSCLC) and breast cancer cells. NUAK2, also called SNARK (Sucrose, non-fermenting 1/AMP-activated protein kinase-related kinase), is involved in energy metabolism. It is activated by hyperosmotic stress, DNA damage, and nutrients such as glucose and glutamine. NUAK2-knockout mice develop obesity, altered serum lipid profiles, hyperinsulinaemia, hyperglycaemia, and impaired glucose tolerance. The NUAK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinases, Never In Mitosis gene A (NIMA)-related kinase 6 and 7; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Nek6 and Nek7 are the shortest Neks, consisting only of the catalytic domain and a very short N-terminal extension. They show distinct expression patterns and both appear to be downstream substrates of Nek9. They are required for mitotic spindle formation and cytokinesis. They may also be regulators of the p70 ribosomal S6 kinase. Nek6/7 is part of a family of 11 different Neks (Nek1-11) that are involved in cell cycle control. The Nek family is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Dual-specificity protein kinase, Testicular protein kinase; Dual-specificity PKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine as well as tyrosine residues on protein substrates. TESK proteins phosphorylate cofilin and induce actin cytoskeletal reorganization. In the Drosphila eye, TESK is required for epithelial cell organization. Mammals contain two TESK proteins, TESK1 and TESK2, which are highly expressed in testis and play roles in spermatogenesis. TESK1 is found in testicular germ cells while TESK2 is expressed mainly in nongerminal Sertoli cells. TESK1 is stimulated by integrin-mediated signaling pathways. It regulates cell spreading and focal adhesion formation. The TESK subfamily is part of a larger superfamily that includes the catalytic domains of other protein serine/threonine PKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-486 7.99e-25

Catalytic domain of testis-specific serine/threonine kinase 4 and similar proteins; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. TSSK proteins are almost exclusively expressed postmeiotically in the testis and play important roles in spermatogenesis and/or spermiogenesis. There are five mammalian TSSK proteins which show differences in their localization and timing of expression. TSSK4, also called TSSK5, is expressed in testis from haploid round spermatids to mature spermatozoa. It phosphorylates Cre-Responsive Element Binding protein (CREB), facilitating the binding of CREB to the specific cis cAMP responsive element (CRE), which is important in activating genes related to germ cell differentiation. Mutations in the human TSSK4 gene is associated with infertile Chinese men with impaired spermatogenesis. The TSSK4-like subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinases, fungal Bck1-like Mitogen-Activated Protein Kinase Kinase Kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Members of this group include the MAPKKKs Saccharomyces cerevisiae Bck1 and Schizosaccharomyces pombe Mkh1, and related proteins. Budding yeast Bck1 is part of the cell integrity MAPK pathway, which is activated by stresses and aggressions to the cell wall. The MAPKKK Bck1, MAPKKs Mkk1 and Mkk2, and the MAPK Slt2 make up the cascade that is important in the maintenance of cell wall homeostasis. Fission yeast Mkh1 is involved in MAPK cascades regulating cell morphology, cell wall integrity, salt resistance, and filamentous growth in response to stress. MAPKKKs phosphorylate and activate MAPK kinases, which in turn phosphorylate and activate MAPKs during signaling cascades that are important in mediating cellular responses to extracellular signals. The Bck1 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

293-534 1.21e-24

Catalytic domain of the Serine/Threonine Kinase, Hormonally up-regulated Neu-associated kinase (also called MAK-V); STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. HUNK/MAK-V was identified from a mammary tumor in an MMTV-neu transgenic mouse. It is required for the metastasis of c-myc-induced mammary tumors, but is not necessary for c-myc-induced primary tumor formation or normal development. It is required for HER2/neu-induced tumor formation and maintenance of the cells' tumorigenic phenotype. It is over-expressed in aggressive subsets of ovary, colon, and breast carcinomas. HUNK interacts with synaptopodin, and may also play a role in synaptic plasticity. The HUNK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

293-534 1.68e-24

Catalytic domain of the Serine/Threonine kinase, Unc-51-like kinase 3; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. The ATG1/ULK complex is conserved from yeast to humans and it plays a critical role in the initiation of autophagy, the intracellular system that leads to the lysosomal degradation of cellular components and their recycling into basic metabolic units. ULK3 mRNA is up-regulated in fibroblasts after Ras-induced senescence, and its overexpression induces both autophagy and senescence in a fibroblast cell line. ULK3, through its kinase activity, positively regulates Gli proteins, mediators of the Sonic hedgehog (Shh) signaling pathway that is implicated in tissue homeostasis maintenance and neurogenesis. It is inhibited by binding to Suppressor of Fused (Sufu). The ULK3 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Phosphoinositide-dependent kinase 1; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. PDK1 carries an N-terminal catalytic domain and a C-terminal pleckstrin homology (PH) domain that binds phosphoinositides. It phosphorylates the activation loop of AGC kinases that are regulated by PI3K such as PKB, SGK, and PKC, among others, and is crucial for their activation. Thus, it contributes in regulating many processes including metabolism, growth, proliferation, and survival. PDK1 also has the ability to autophosphorylate and is constitutively active in mammalian cells. It is essential for normal embryo development and is important in regulating cell volume. The PDK1 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-529 1.07e-23

Catalytic domain of the Serine/Threonine Kinase, cGMP-dependent protein kinase (cGK or PKG); STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Mammals have two cGK isoforms from different genes, cGKI and cGKII. cGKI exists as two splice variants, cGKI-alpha and cGKI-beta. cGK consists of an N-terminal regulatory domain containing a dimerization and an autoinhibitory pseudosubstrate region, two cGMP-binding domains, and a C-terminal catalytic domain. Binding of cGMP to both binding sites releases the inhibition of the catalytic center by the pseudosubstrate region, allowing autophosphorylation and activation of the kinase. cGKI is a soluble protein expressed in all smooth muscles, platelets, cerebellum, and kidney. It is also expressed at lower concentrations in other tissues. cGKII is a membrane-bound protein that is most abundantly expressed in the intestine. It is also present in the brain nuclei, adrenal cortex, kidney, lung, and prostate. cGKI is involved in the regulation of smooth muscle tone, smooth cell proliferation, and platelet activation. cGKII plays a role in the regulation of secretion, such as renin secretion by the kidney and aldosterone secretion by the adrenal. It also regulates bone growth and the circadian rhythm. The cGK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinases, fungal Byr2-like Mitogen-Activated Protein Kinase Kinase Kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Members of this group include the MAPKKKs Schizosaccharomyces pombe Byr2, Saccharomyces cerevisiae and Cryptococcus neoformans Ste11, and related proteins. They contain an N-terminal SAM (sterile alpha-motif) domain, which mediates protein-protein interaction, and a C-terminal catalytic domain. MAPKKKs phosphorylate and activate MAPK kinases, which in turn phosphorylate and activate MAPKs during signaling cascades that are important in mediating cellular responses to extracellular signals. Fission yeast Byr2 is regulated by Ras1. It responds to pheromone signaling and controls mating through the MAPK pathway. Budding yeast Ste11 functions in MAPK cascades that regulate mating, high osmolarity glycerol, and filamentous growth responses. The Byr2 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

289-534 1.75e-23

Catalytic domain of Serine/Threonine Kinase 25 (also called Yeast Sps1/Ste20-related kinase 1); STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. STK25 is also called Ste20/oxidant stress response kinase 1 (SOK1) or yeast Sps1/Ste20-related kinase 1 (YSK1). It is localized in the Golgi apparatus through its interaction with the Golgi matrix protein GM130. It may be involved in the regulation of cell migration and polarization. STK25 binds and phosphorylates CCM3 (cerebral cavernous malformation 3), also called PCD10 (programmed cell death 10), and may play a role in apoptosis. Human STK25 is a candidate gene responsible for pseudopseudohypoparathyroidism (PPHP), a disease that shares features with the Albright hereditary osteodystrophy (AHO) phenotype. The STK25 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

173-262 4.08e-23

Src homology 2 (SH2) domain found in the Src family of non-receptor tyrosine kinases; The Src family kinases are nonreceptor tyrosine kinases that have been implicated in pathways regulating proliferation, angiogenesis, invasion and metastasis, and bone metabolism. It is thought that transforming ability of Src is linked to its ability to activate key signaling molecules in these pathways, rather than through direct activity. As such blocking Src activation has been a target for drug companies. Src family members can be divided into 3 groups based on their expression pattern: 1) Src, Fyn, and Yes; 2) Blk, Fgr, Hck, Lck, and Lyn; and 3) Frk-related kinases Frk/Rak and Iyk/Bsk Of these, cellular c-Src is the best studied and most frequently implicated in oncogenesis. The c-Src contains five distinct regions: a unique N-terminal domain, an SH3 domain, an SH2 domain, a kinase domain and a regulatory tail, as do the other members of the family. Src exists in both active and inactive conformations. Negative regulation occurs through phosphorylation of Tyr, resulting in an intramolecular association between phosphorylated Tyr and the SH2 domain of SRC, which locks the protein in a closed conformation. Further stabilization of the inactive state occurs through interactions between the SH3 domain and a proline-rich stretch of residues within the kinase domain. Conversely, dephosphorylation of Tyr allows SRC to assume an open conformation. Full activity requires additional autophosphorylation of a Tyr residue within the catalytic domain. Loss of the negative-regulatory C-terminal segment has been shown to result in increased activity and transforming potential. Phosphorylation of the C-terminal Tyr residue by C-terminal Src kinase (Csk) and Csk homology kinase results in increased intramolecular interactions and consequent Src inactivation. Specific phosphatases, protein tyrosine phosphatase a (PTPa) and the SH-containing phosphatases SHP1/SHP2, have also been shown to take a part in Src activation. Src is also activated by direct binding of focal adhesion kinase (Fak) and Crk-associated substrate (Cas) to the SH2 domain. SRC activity can also be regulated by numerous receptor tyrosine kinases (RTKs), such as Her2, epidermal growth factor receptor (EGFR), fibroblast growth factor receptor, platelet-derived growth factor receptor (PDGFR), and vascular endothelial growth factor receptor (VEGFR). In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

Catalytic domain of the Serine/Threonine Kinase, Mammalian Ste20-like protein kinase 3; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. MST3 phosphorylates the STK NDR and may play a role in cell cycle progression and cell morphology. It may also regulate paxillin and consequently, cell migration. MST3 is present in human placenta, where it plays an essential role in the oxidative stress-induced apoptosis of trophoblasts in normal spontaneous delivery. Dysregulation of trophoblast apoptosis may result in pregnancy complications such as preeclampsia and intrauterine growth retardation. The MST3 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Doublecortin-like kinase (also called Doublecortin-like and CAM kinase-like); STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. DCKL (or DCAMKL) proteins belong to the doublecortin (DCX) family of proteins which are involved in neuronal migration, neurogenesis, and eye receptor development, among others. Family members typically contain tandem doublecortin (DCX) domains at the N-terminus; DCX domains can bind microtubules and serve as protein-interaction platforms. In addition, DCKL proteins contain a C-terminal kinase domain with similarity to CAMKs. They are involved in the regulation of cAMP signaling. Vertebrates contain three DCKL proteins (DCKL1-3); DCKL1 and 2 also contain a serine, threonine, and proline rich domain (SP), while DCKL3 contains only a single DCX domain instead of tandem domains. The DCKL subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of Cyclin-Dependent protein Kinase 9-like Serine/Threonine Kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. This subfamily is composed of CDK9 and CDK12 from higher eukaryotes, yeast BUR1, C-type plant CDKs (CdkC), and similar proteins. CDK9, BUR1, and CdkC are functionally equivalent. They act as a kinase for the C-terminal domain of RNA polymerase II and participate in regulating mutliple steps of gene expression including transcription elongation and RNA processing. CDK9 and CdkC associate with T-type cyclins while BUR1 associates with the cyclin BUR2. CDK12 is a unique CDK that contains an arginine/serine-rich (RS) domain, which is predominantly found in splicing factors. CDK12 interacts with cyclins L1 and L2, and participates in regulating transcription and alternative splicing. CDKs belong to a large family of STKs that are regulated by their cognate cyclins. Together, they are involved in the control of cell-cycle progression, transcription, and neuronal function. The CDK9-like subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine kinase, Receptor Interacting Protein 2; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. RIP2, also called RICK or CARDIAK, harbors a C-terminal Caspase Activation and Recruitment domain (CARD) belonging to the Death domain (DD) superfamily. It functions as an effector kinase downstream of the pattern recognition receptors from the Nod-like (NLR) family, Nod1 and Nod2, which recognizes bacterial peptidoglycans released upon infection. RIP2 may also be involved in regulating wound healing and keratinocyte proliferation. RIP kinases serve as essential sensors of cellular stress. The RIP2 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-542 1.42e-22

Catalytic domain of the Serine/Threonine Kinase, Leucine-Rich Repeat Kinase 2; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. LRRK2 is one of two vertebrate LRRKs which show complementary expression in the brain. Mutations in LRRK2, found in the kinase, ROC-COR, and WD40 domains, are linked to both familial and sporadic forms of Parkinson's disease. The most prevalent mutation, G2019S located in the activation loop of the kinase domain, increases kinase activity. The R1441C/G mutations in the GTPase domain have also been reported to influence kinase activity. LRRKs are also classified as ROCO proteins because they contain a ROC (Ras of complex proteins)/GTPase domain followed by a COR (C-terminal of ROC) domain of unknown function. In addition, LRRKs contain a catalytic kinase domain and protein-protein interaction motifs including a WD40 domain, LRRs and ankyrin (ANK) repeats. LRRKs possess both GTPase and kinase activities, with the ROC domain acting as a molecular switch for the kinase domain, cycling between a GTP-bound state which drives kinase activity and a GDP-bound state which decreases the activity. The LRRK2 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

280-530 1.43e-22

Catalytic domain of the Serine/Threonine kinase, Aurora-A kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Aurora kinases are key regulators of mitosis and are essential for the accurate and equal division of genomic material from parent to daughter cells. Vertebrates contain at least 2 Aurora kinases (A and B); mammals contains a third Aurora kinase gene (C). Aurora-A regulates cell cycle events from the late S-phase through the M-phase including centrosome maturation, mitotic entry, centrosome separation, spindle assembly, chromosome alignment, cytokinesis, and mitotic exit. Aurora-A activation depends on its autophosphorylation and binding to the microtubule-associated protein TPX2, which also localizes the kinase to spindle microtubules. Aurora-A is overexpressed in many cancer types such as prostate, ovarian, breast, bladder, gastric, and pancreatic. The Aurora subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

290-534 2.17e-22

Catalytic domain of the Serine/Threonine Kinase, novel (nua) kinase family NUAK 2; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. NUAK proteins are classified as AMP-activated protein kinase (AMPK)-related kinases, which like AMPK are activated by the major tumor suppressor LKB1. Vertebrates contain two NUAK proteins, called NUAK1 and NUAK2. NUAK2, also called SNARK (Sucrose, non-fermenting 1/AMP-activated protein kinase-related kinase), is involved in energy metabolism. It is activated by hyperosmotic stress, DNA damage, and nutrients such as glucose and glutamine. NUAK2-knockout mice develop obesity, altered serum lipid profiles, hyperinsulinaemia, hyperglycaemia, and impaired glucose tolerance. NUAK2 is implicated in regulating actin stress fiber assembly through its association with myosin phosphatase Rho-interacting protein (MRIP), which leads to an increase in myosin regulatory light chain (MLC) phosphorylation. It is also associated with tumor growth, migration, and oncogenicity of melanoma cells. The NUAK2 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of Mitogen-activated protein kinase kinase kinase kinase (MAP4K) 3-like Serine/Threonine Kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. This subfamily includes MAP4K3, MAP4K1, MAP4K2, MAP4K5, and related proteins. Vertebrate members contain an N-terminal catalytic domain and a C-terminal citron homology (CNH) regulatory domain. MAP4K1, also called haematopoietic progenitor kinase 1 (HPK1), is a hematopoietic-specific STK involved in many cellular signaling cascades including MAPK, antigen receptor, apoptosis, growth factor, and cytokine signaling. It participates in the regulation of T cell receptor signaling and T cell-mediated immune responses. MAP4K2 was referred to as germinal center (GC) kinase because of its preferred location in GC B cells. MAP4K3 plays a role in the nutrient-responsive pathway of mTOR (mammalian target of rapamycin) signaling. It is required in the activation of S6 kinase by amino acids and for the phosphorylation of the mTOR-regulated inhibitor of eukaryotic initiation factor 4E. MAP4K5, also called germinal center kinase-related enzyme (GCKR), has been shown to activate the MAPK c-Jun N-terminal kinase (JNK). The MAP4K3-like subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Protein Serine/Threonine Kinase, Never In Mitosis gene A (NIMA)-related kinase 8; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Nek8 contains an N-terminal kinase catalytic domain and a C-terminal RCC1 (regulator of chromosome condensation) domain. A double point mutation in Nek8 causes cystic kidney disease in mice that genetically resembles human autosomal recessive polycystic kidney disease (ARPKD). Nek8 is also associated with a rare form of juvenile renal cystic disease, nephronophthisis type 9. It has been suggested that a defect in the ciliary localization of Nek8 contributes to the development of cysts manifested by these diseases. Nek8 is one in a family of 11 different Neks (Nek1-11) that are involved in cell cycle control. The Nek family is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Cyclin-Dependent protein Kinase 7; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. CDK7 plays essential roles in the cell cycle and in transcription. It associates with cyclin H and MAT1 and acts as a CDK-Activating Kinase (CAK) by phosphorylating and activating cell cycle CDKs (CDK1/2/4/6). In the brain, it activates CDK5. CDK7 is also a component of the general transcription factor TFIIH, which phosphorylates the C-terminal domain (CTD) of RNA polymerase II when it is bound with unphosphorylated DNA, as present in the pre-initiation complex. Following phosphorylation, the CTD dissociates from the DNA which allows transcription initiation. CDKs belong to a large family of STKs that are regulated by their cognate cyclins. Together, they are involved in the control of cell-cycle progression, transcription, and neuronal function. The CDK7 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

287-531 3.36e-22

Catalytic domain of the Serine/Threonine Kinases, Chlamydomonas reinhardtii CNK2 and similar proteins; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Chlamydomonas reinhardtii CNK2 has both cilliary and cell cycle functions. It influences flagellar length through promoting flagellar disassembly, and it regulates cell size, through influencing the size threshold at which cells commit to mitosis. This subfamily belongs to the (NIMA)-related kinase (Nek) family, which includes seven different Chlamydomonas Neks (CNKs 1-6 and Fa2). This subfamily includes CNK1, and -2. The Nek family is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-532 4.08e-22

Pseudokinase (repeat 1) domain of the Protein Tyrosine Kinase, Janus kinase 2; Jak2 is widely expressed in many tissues. It is essential for the signaling of hormone-like cytokines such as growth hormone, erythropoietin, thrombopoietin, and prolactin, as well as some IFNs and cytokines that signal through the IL-3 and gp130 receptors. Disruption of Jak2 in mice results in an embryonic lethal phenotype with multiple defects including erythropoietic and cardiac abnormalities. It is the only Jak gene that results in a lethal phenotype when disrupted in mice. A mutation in the pseudokinase domain of Jak2, V617F, is present in many myeloproliferative diseases, including almost all patients with polycythemia vera, and 50% of patients with essential thrombocytosis and myelofibrosis. Jak2 is a cytoplasmic (or nonreceptor) PTK containing an N-terminal FERM domain, followed by a Src homology 2 (SH2) domain, a pseudokinase domain, and a C-terminal tyr kinase domain. The pseudokinase domain shows similarity to tyr kinases but lacks crucial residues for catalytic activity and ATP binding. Despite this, the presumed pseudokinase (repeat 1) domain of Jak2 exhibits dual-specificity kinase activity, phosphorylating two negative regulatory sites in Jak2: Ser523 and Tyr570. Inactivation of the repeat 1 domain increased Jak2 basal activity, suggesting that it modulates the kinase activity of the C-terminal catalytic (repeat 2) domain. The Jak2 subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinases, Cyclin-Dependent protein Kinase Like 2 and 3; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. CDKL2, also called p56 KKIAMRE, is expressed in testis, kidney, lung, and brain. It functions mainly in mature neurons and plays an important role in learning and memory. Inactivation of CDKL3, also called NKIAMRE (NKIATRE in rat), by translocation is associated with mild mental retardation. It has been reported that CDKL3 is lost in leukemic cells having a chromosome arm 5q deletion, and may contribute to the transformed phenotype. CDKs belong to a large family of STKs that are regulated by their cognate cyclins. Together, they are involved in the control of cell-cycle progression, transcription, and neuronal function. The CDKL2/3 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, NIM1; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. NIM1 is a widely-expressed kinase belonging to the AMP-activated protein kinase (AMPK) subfamily. Although present in most tissues, NIM1 kinase activity is only observed in the brain and testis. NIM1 is capable of autophosphorylating and activating itself, but may be present in other tissues in the inactive form. The physiological function of NIM1 has yet to be elucidated. The NIM1 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

293-486 6.21e-22

Catalytic domain of the Serine/Threonine Kinase, Group I p21-activated kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Group I PAKs, also called conventional PAKs, include PAK1, PAK2, and PAK3. Group I PAKs contain a PBD (p21-binding domain) overlapping with an AID (autoinhibitory domain), a C-terminal catalytic domain, SH3 binding sites and a non-classical SH3 binding site for PIX (PAK-interacting exchange factor). They interact with the SH3 domain containing proteins Nck, Grb2 and PIX. Binding of group I PAKs to activated GTPases leads to conformational changes that destabilize the AID, allowing autophosphorylation and full activation of the kinase domain. Known group I PAK substrates include MLCK, Bad, Raf, MEK1, LIMK, Merlin, Vimentin, Myc, Stat5a, and Aurora A, among others. PAKs are Rho family GTPase-regulated kinases that serve as important mediators in the function of Cdc42 (cell division cycle 42) and Rac. PAKs are implicated in the regulation of many cellular processes including growth factor receptor-mediated proliferation, cell polarity, cell motility, cell death and survival, and actin cytoskeleton organization. The PAK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic kinase domain of Myosin Light Chain Kinase-like Serine/Threonine Kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. This family is composed of MLCKs and related MLCK-like kinase domains from giant STKs such as titin, obscurin, SPEG, Unc-89, Trio, kalirin, and Twitchin. Also included in this family are Death-Associated Protein Kinases (DAPKs) and Death-associated protein kinase-Related Apoptosis-inducing protein Kinase (DRAKs). MLCK phosphorylates myosin regulatory light chain and controls the contraction of all muscle types. Titin, obscurin, Twitchin, and SPEG are muscle proteins involved in the contractile apparatus. The giant STKs are multidomain proteins containing immunoglobulin (Ig), fibronectin type III (FN3), SH3, RhoGEF, PH and kinase domains. Titin, obscurin, Twitchin, and SPEG contain many Ig domain repeats at the N-terminus, while Trio and Kalirin contain spectrin-like repeats. The MLCK-like family is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-534 7.17e-22

Catalytic domain of the Serine/Threonine kinases, Unc-51-like kinases 1 and 2, and similar proteins; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. The ATG1/ULK complex is conserved from yeast to humans and it plays a critical role in the initiation of autophagy, the intracellular system that leads to the lysosomal degradation of cellular components and their recycling into basic metabolic units. ULK1 is required for efficient amino acid starvation-induced autophagy and mitochondrial clearance. ULK2 is ubiquitously expressed and is essential in autophagy induction. ULK1 and ULK2 have unique and cell-type specific roles, but also display partially redundant roles in starvation-induced autophagy. They both display neuron-specific functions: ULK1 is involved in non-clathrin-coated endocytosis in growth cones, filopodia extension, and axon branching; ULK2 plays a role in axon development. The ULK1/2 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Protein Serine/Threonine Kinase, Mitogen-Activated Protein (MAP)/Extracellular signal-Regulated Kinase (ERK) Kinase Kinase 4; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. MEKK4 is a MAPK kinase kinase that phosphorylates and activates the c-Jun N-terminal kinase (JNK) and p38 MAPK signaling pathways by directly activating their respective MAPKKs, MKK4/MKK7 and MKK3/MKK6. JNK and p38 are collectively known as stress-activated MAPKs, as they are activated in response to a variety of environmental stresses and pro-inflammatory cytokines. MEKK4 also plays roles in the re-polarization of the actin cytoskeleton in response to osmotic stress, in the proper closure of the neural tube, in cardiovascular development, and in immune responses. The MEKK4 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinases, Transforming Growth Factor beta family Type I Receptors; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. This subfamily is composed of type I receptors for the TGFbeta family of secreted signaling molecules including TGFbeta, bone morphogenetic proteins, activins, growth and differentiation factors, and anti-Mullerian hormone, among others. These receptors contain an extracellular domain that binds ligands, a single transmembrane (TM) region, and a cytoplasmic catalytic kinase domain. Type I receptors are low-affinity receptors that bind ligands only after they are recruited by the ligand/type II high-affinity receptor complex. Following activation through trans-phosphorylation by type II receptors, they start intracellular signaling to the nucleus by phosphorylating SMAD proteins. Type I receptors contain an additional domain located between the TM and kinase domains called the GS domain, which contains the activating phosphorylation site and confers preference for specific SMAD proteins. They are inhibited by the immunophilin FKBP12, which is thought to control leaky signaling caused by receptor oligomerization in the absence of ligand. The TGFbR-I subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Mammalian Ste20-like protein kinase 4; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. MST4 is sometimes referred to as MASK (MST3 and SOK1-related kinase). It plays a role in mitogen-activated protein kinase (MAPK) signaling during cytoskeletal rearrangement, morphogenesis, and apoptosis. It influences cell growth and transformation by modulating the extracellular signal-regulated kinase (ERK) pathway. MST4 may also play a role in tumor formation and progression. It localizes in the Golgi apparatus by interacting with the Golgi matrix protein GM130 and may play a role in cell migration. The MST4 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

AMPK, also called SNF1 (sucrose non-fermenting1) in yeasts and SnRK1 (SNF1-related kinase1) in plants, is a heterotrimeric enzyme composed of a catalytic alpha subunit and two regulatory subunits, beta and gamma. It is a stress-activated kinase that serves as master regulator of glucose and lipid metabolism by monitoring carbon and energy supplies, via sensing the cell's AMP:ATP ratio. In response to decreased ATP levels, it enhances energy-producing processes and inhibits energy-consuming pathways. Once activated, AMPK phosphorylates a broad range of downstream targets, with effects in carbohydrate metabolism and uptake, lipid and fatty acid biosynthesis, carbon energy storage, and inflammation, among others. Defects in energy homeostasis underlie many human diseases including Type 2 diabetes, obesity, heart disease, and cancer. As a result, AMPK has emerged as a therapeutic target in the treatment of these diseases. The AMPK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

312-532 1.78e-21

Pseudokinase (repeat 1) domain of the Protein Tyrosine Kinase, Tyrosine kinase 2; Tyk2 is widely expressed in many tissues. It is involved in signaling via the cytokine receptors IFN-alphabeta, IL-6, IL-10, IL-12, IL-13, and IL-23. It mediates cell surface urokinase receptor (uPAR) signaling and plays a role in modulating vascular smooth muscle cell (VSMC) functional behavior in response to injury. Tyk2 is also important in dendritic cell function and T helper (Th)1 cell differentiation. A homozygous mutation of Tyk2 was found in a patient with hyper-IgE syndrome (HIES), a primary immunodeficiency characterized by recurrent skin abscesses, pneumonia, and elevated serum IgE. This suggests that Tyk2 may play important roles in multiple cytokine signaling involved in innate and adaptive immunity. Tyk2 is a member of the Janus kinase (Jak) subfamily of proteins, which are cytoplasmic (or nonreceptor) PTKs containing an N-terminal FERM domain, followed by a Src homology 2 (SH2) domain, a pseudokinase domain, and a C-terminal tyr kinase domain. The pseudokinase domain shows similarity to tyr kinases but lacks crucial residues for catalytic activity and ATP binding. It modulates the kinase activity of the C-terminal catalytic domain. The Tyk2 subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

286-478 1.81e-21

Catalytic subunit of the Serine/Threonine Kinases, cAMP-dependent protein kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. This subfamily is composed of the cAMP-dependent protein kinases, PKA and PRKX, and similar proteins. The inactive PKA holoenzyme is a heterotetramer composed of two phosphorylated and active catalytic subunits with a dimer of regulatory (R) subunits. Activation is achieved through the binding of the important second messenger cAMP to the R subunits, which leads to the dissociation of PKA into the R dimer and two active subunits. PKA is present ubiquitously in cells and interacts with many different downstream targets. It plays a role in the regulation of diverse processes such as growth, development, memory, metabolism, gene expression, immunity, and lipolysis. PRKX is also reulated by the R subunit and is is present in many tissues including fetal and adult brain, kidney, and lung. It is implicated in granulocyte/macrophage lineage differentiation, renal cell epithelial migration, and tubular morphogenesis in the developing kidney. The PKA-like subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine kinase, eukaryotic translation Initiation Factor 2-Alpha Kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. EIF2AKs phosphorylate the alpha subunit of eIF-2, resulting in the downregulation of protein synthesis. eIF-2 phosphorylation is induced in response to cellular stresses including virus infection, heat shock, nutrient deficiency, and the accummulation of unfolded proteins, among others. There are four distinct kinases that phosphorylate eIF-2 and control protein synthesis under different stress conditions: General Control Non-derepressible-2 (GCN2) which is activated during amino acid or serum starvation; protein kinase regulated by RNA (PKR) which is activated by double stranded RNA; heme-regulated inhibitor kinase (HRI) which is activated under heme-deficient conditions; and PKR-like endoplasmic reticulum kinase (PERK) which is activated when misfolded proteins accumulate in the ER. The EIF2AK subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinases, Polo-like kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. PLKs play important roles in cell cycle progression and in DNA damage responses. They regulate mitotic entry, mitotic exit, and cytokinesis. In general PLKs contain an N-terminal catalytic kinase domain and a C-terminal regulatory polo box domain (PBD), which is comprised by two bipartite polo-box motifs (or polo boxes) and is involved in protein interactions. PLKs derive their names from homology to polo, a kinase first identified in Drosophila. There are five mammalian PLKs (PLK1-5) from distinct genes. There is good evidence that PLK1 may function as an oncogene while PLK2-5 have tumor suppressive properties. PLK1 functions as a positive regulator of mitosis, meiosis, and cytokinesis. PLK2 functions in G1 progression, S-phase arrest, and centriole duplication. PLK3 regulates angiogenesis and responses to DNA damage. PLK4 is required for late mitotic progression, cell survival, and embryonic development. PLK5 was first identified as a pseudogene containing a stop codon within the kinase domain, however, both murine and human genes encode expressed proteins. PLK5 functions in cell cycle arrest.

292-507 4.58e-21

Catalytic domain of the Serine/Threonine Kinase, Novel Protein Kinase C theta; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. PKC-theta is selectively expressed in T-cells and plays an important and non-redundant role in several aspects of T-cell biology. Although T-cells also express other PKC isoforms, PKC-theta is unique in that upon antigen stimulation, it is translocated to the plasma membrane at the immunological synapse, where it mediates signals essential for T-cell activation. It is essential for TCR-induced proliferation, cytokine production, T-cell survival, and the differentiation and effector function of T-helper (Th) cells, particularly Th2 and Th17. PKC-theta is being developed as a therapeutic target for Th2-mediated allergic inflammation and Th17-mediated autoimmune diseases. PKCs are classified into three groups (classical, atypical, and novel) depending on their mode of activation and the structural characteristics of their regulatory domain. nPKCs are calcium-independent, but require DAG (1,2-diacylglycerol) and phosphatidylserine (PS) for activity. The nPKC subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinases, MAP/microtubule affinity-regulating kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. MARKs, also called Partitioning-defective 1 (Par1) proteins, function as regulators of diverse cellular processes in nematodes, Drosophila, yeast, and vertebrates. They are involved in embryogenesis, epithelial cell polarization, cell signaling, and neuronal differentiation. MARKs phosphorylate tau and related microtubule-associated proteins (MAPs), and regulates microtubule-based intracellular transport. Vertebrates contain four isoforms, namely MARK1 (or Par1c), MARK2 (or Par1b), MARK3 (Par1a), and MARK4 (or MARKL1). Known substrates of MARKs include the cell cycle-regulating phosphatase Cdc25, tyrosine phosphatase PTPH1, MAPK scaffolding protein KSR1, class IIa histone deacetylases, and plakophilin 2. The MARK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinases, Salt-Inducible kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. SIKs are part of a complex network that regulates Na,K-ATPase to maintain sodium homeostasis and blood pressure. Vertebrates contain three forms of SIKs (SIK1-3) from three distinct genes, which display tissue-specific effects. SIK1, also called SNF1LK, controls steroidogenic enzyme production in adrenocortical cells. In the brain, both SIK1 and SIK2 regulate energy metabolism. SIK2, also called QIK or SNF1LK2, is involved in the regulation of gluconeogenesis in the liver and lipogenesis in adipose tissues, where it phosphorylates the insulin receptor substrate-1. In the liver, SIK3 (also called QSK) regulates cholesterol and bile acid metabolism. In addition, SIK2 plays an important role in the initiation of mitosis and regulates the localization of C-Nap1, a centrosome linker protein. The SIK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-531 8.76e-21

Catalytic domain of testis-specific serine/threonine kinase 6 and similar proteins; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. TSSK proteins are almost exclusively expressed postmeiotically in the testis and play important roles in spermatogenesis and/or spermiogenesis. There are five mammalian TSSK proteins which show differences in their localization and timing of expression. TSSK6, also called SSTK, is expressed at the head of elongated sperm. It can phosphorylate histones and associate with heat shock protens HSP90 and HSC70. Male mice deficient in TSSK6 are infertile, showing spermatogenic impairment including reduced sperm counts, impaired DNA condensation, abnormal morphology and decreased motility rates. The TSSK6-like subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

275-488 1.44e-20

Catalytic domain of the Serine/Threonine Kinase, Doublecortin-like kinase 1 (also called Doublecortin-like and CAM kinase-like 1); STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. DCKL1 (or DCAMKL1) belongs to the doublecortin (DCX) family of proteins which are involved in neuronal migration, neurogenesis, and eye receptor development, among others. Family members typically contain tandem doublecortin (DCX) domains at the N-terminus; DCX domains can bind microtubules and serve as protein-interaction platforms. In addition, DCKL1 contains a serine, threonine, and proline rich domain (SP) and a C-terminal kinase domain with similarity to CAMKs. DCKL1 interacts with tubulin, glucocorticoid receptor, dynein, JIP1/2, caspases (3 and 8), and calpain, among others. It plays roles in neurogenesis, neuronal migration, retrograde transport, and neuronal apoptosis. The DCKL1 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-534 1.69e-20

Catalytic domain of the Serine/Threonine kinase, Liver Kinase B1; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. LKB1, also called STK11, was first identified as a tumor suppressor responsible for Peutz-Jeghers syndrome, a disorder that leads to an increased risk of spontaneous epithelial cancer. It serves as a master upstream kinase that activates AMP-activated protein kinase (AMPK) and most AMPK-like kinases. LKB1 and AMPK are part of an energy-sensing pathway that links cell energy to metabolism and cell growth. They play critical roles in the establishment and maintenance of cell polarity, cell proliferation, cytoskeletal organization, as well as T-cell metabolism, including T-cell development, homeostasis, and effector function. To be activated, LKB1 requires the adaptor proteins STe20-Related ADaptor (STRAD) and mouse protein 25 (MO25). The LKB1 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine kinase, Cell cycle Checkpoint Kinase 2; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Checkpoint Kinase 2 (Chk2) plays an important role in cellular responses to DNA double-strand breaks and related lesions. It is phosphorylated and activated by ATM kinase, resulting in its dissociation from sites of damage to phosphorylate downstream targets such as BRCA1, p53, cell cycle transcription factor E2F1, the promyelocytic leukemia protein (PML) involved in apoptosis, and CDC25 phosphatases, among others. Mutations in Chk2 is linked to a variety of cancers including familial breast cancer, myelodysplastic syndromes, prostate cancer, lung cancer, and osteosarcomas. Chk2 contains an N-terminal SQ/TQ cluster domain (SCD), a central forkhead-associated (FHA) domain, and a C-terminal catalytic kinase domain. The Chk2 subfamily is part of a larger superfamily that includes the catalytic domains of other protein kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, BRI1 associated kinase 1 and related STKs; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. This subfamily includes three leucine-rich repeat receptor-like kinases (LRR-RLKs): Arabidopsis thaliana BAK1 and CLAVATA1 (CLV1), and Physcomitrella patens CLL1B clavata1-like receptor S/T protein kinase. BAK1 functions in various signaling pathways. It plays a role in BR (brassinosteroid)-regulated plant development as a co-receptor of BRASSINOSTEROID (BR) INSENSITIVE 1 (BRI1), the receptor for BRs, and is required for full activation of BR signaling. It also modulates pathways involved in plant resistance to pathogen infection (pattern-triggered immunity, PTI) and herbivore attack (wound- or herbivore feeding-induced accumulation of jasmonic acid (JA) and JA-isoleucine. CLV1, directly binds small signaling peptides, CLAVATA3 (CLV3) and CLAVATA3/EMBRYO SURROUNDING REGI0N (CLE), to restrict stem cell proliferation: the CLV3-CLV1-WUS (WUSCHEL) module influences stem cell maintenance in the shoot apical meristem, and the CLE40 (CLAVATA3/EMBRYO SURROUNDING REGION40) -ACR4 (CRINKLY4) -CLV1- WOX5 (WUSCHEL-RELATED HOMEOBOX5) module at the root apical meristem. The STK_BAK1-like subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-531 2.50e-20

Catalytic domain of the Serine/Threonine kinase, Oocyte maturation factor Mos; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Mos (or c-Mos) is a germ-cell specific kinase that plays roles in both the release of primary arrest and the induction of secondary arrest in oocytes. It is expressed towards the end of meiosis I and is quickly degraded upon fertilization. It is a component of the cytostatic factor (CSF), which is responsible for metaphase II arrest. In addition, Mos activates a phoshorylation cascade that leads to the activation of the p34 subunit of MPF (mitosis-promoting factor or maturation promoting factor), a cyclin-dependent kinase that is responsible for the release of primary arrest in meiosis I. The Mos subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

280-534 2.54e-20

Catalytic domain of the dual-specificity Protein Kinase, Mitogen-activated protein Kinase Kinase 7; PKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine (ST) or tyrosine residues on protein substrates. MKK7 is a dual-specificity PK that phosphorylates and activates its downstream target, c-Jun N-terminal kinase (JNK), on specific threonine and tyrosine residues. Although MKK7 is capable of dual phosphorylation, it prefers to phosphorylate the threonine residue of JNK. Thus, optimal activation of JNK requires both MKK4 and MKK7. MKK7 is primarily activated by cytokines. MKK7 is essential for liver formation during embryogenesis. It plays roles in G2/M cell cycle arrest and cell growth. In addition, it is involved in the control of programmed cell death, which is crucial in oncogenesis, cancer chemoresistance, and antagonism to TNFalpha-induced killing, through its inhibition by Gadd45beta and the subsequent suppression of the JNK cascade. The MKK7 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

172-265 2.90e-20

Src homology 2 (SH2) domain found in SH2-containing inositol-5'-phosphatase (SHIP) and SLAM-associated protein (SAP); The SH2-containing inositol-5'-phosphatase, SHIP (also called SHIP1/SHIP1a), is a hematopoietic-restricted phosphatidylinositide phosphatase that translocates to the plasma membrane after extracellular stimulation and hydrolyzes the phosphatidylinositol-3-kinase (PI3K)-generated second messenger PI-3,4,5-P3 (PIP3) to PI-3,4-P2. As a result, SHIP dampens down PIP3 mediated signaling and represses the proliferation, differentiation, survival, activation, and migration of hematopoietic cells. PIP3 recruits lipid-binding pleckstrin homology(PH) domain-containing proteins to the inner wall of the plasma membrane and activates them. PH domain-containing downstream effectors include the survival/proliferation enhancing serine/threonine kinase, Akt (protein kinase B), the tyrosine kinase, Btk, the regulator of protein translation, S6K, and the Rac and cdc42 guanine nucleotide exchange factor, Vav. SHIP is believed to act as a tumor suppressor during leukemogenesis and lymphomagenesis, and may play a role in activating the immune system to combat cancer. SHIP contains an N-terminal SH2 domain, a centrally located phosphatase domain that specifically hydrolyzes the 5'-phosphate from PIP3, PI-4,5-P2 and inositol-1,3,4,5- tetrakisphosphate (IP4), a C2 domain, that is an allosteric activating site when bound by SHIP's enzymatic product, PI-3,4-P2; 2 NPXY motifs that bind proteins with a phosphotyrosine binding (Shc, Dok 1, Dok 2) or an SH2 (p85a, SHIP2) domain; and a proline-rich domain consisting of four PxxP motifs that bind a subset of SH3-containing proteins including Grb2, Src, Lyn, Hck, Abl, PLCg1, and PIAS1. The SH2 domain of SHIP binds to the tyrosine phosphorylated forms of Shc, SHP-2, Doks, Gabs, CD150, platelet-endothelial cell adhesion molecule, Cas, c-Cbl, immunoreceptor tyrosine-based inhibitory motifs (ITIMs), and immunoreceptor tyrosine-based activation motifs (ITAMs). The X-linked lymphoproliferative syndrome (XLP) gene encodes SAP (also called SH2D1A/DSHP) a protein that consists of a 5 residue N-terminus, a single SH2 domain, and a short 25 residue C-terminal tail. XLP is characterized by an extreme sensitivity to Epstein-Barr virus. Both T and natural killer (NK) cell dysfunctions have been seen in XLP patients. SAP binds the cytoplasmic tail of Signaling lymphocytic activation molecule (SLAM), 2B4, Ly-9, and CD84. SAP is believed to function as a signaling inhibitor, by blocking or regulating binding of other signaling proteins. SAP and the SAP-like protein EAT-2 recognize the sequence motif TIpYXX(V/I), which is found in the cytoplasmic domains of a restricted number of T, B, and NK cell surface receptors and are proposed to be natural inhibitors or regulators of the physiological role of a small family of receptors on the surface of these cells. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

287-534 3.00e-20

Catalytic domain of the yeast Serine/Threonine Kinases, Rad53 and Cds1; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Rad53 and Cds1 are the checkpoint kinase 2 (Chk2) homologs found in budding and fission yeast, respectively. They play a central role in the cell's response to DNA lesions to prevent genome rearrangements and maintain genome integrity. They are phosphorylated in response to DNA damage and incomplete replication, and are essential for checkpoint control. They help promote DNA repair by stalling the cell cycle prior to mitosis in the presence of DNA damage. The Rad53/Cds1 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Never In Mitosis gene A (NIMA)-related kinase 2; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. The Nek2 subfamily includes Aspergillus nidulans NIMA kinase, the founding member of the Nek family, which was identified in a screen for cell cycle mutants prevented from entering mitosis. NIMA is essential for mitotic entry and progression through mitosis, and its degradation is essential for mitotic exit. NIMA is involved in nuclear membrane fission. Vertebrate Nek2 is a cell cycle-regulated STK, localized in centrosomes and kinetochores, that regulates centrosome splitting at the G2/M phase. It also interacts with other mitotic kinases such as Polo-like kinase 1 and may play a role in spindle checkpoint. An increase in the expression of the human NEK2 gene is strongly associated with the progression of non-Hodgkin lymphoma. Nek2 is one in a family of 11 different Neks (Nek1-11) that are involved in cell cycle control. It The Nek family is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, p21-activated kinase 2; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. PAK2 plays a role in pro-apoptotic signaling. It is cleaved and activated by caspases leading to morphological changes during apoptosis. PAK2 is also activated in response to a variety of stresses including DNA damage, hyperosmolarity, serum starvation, and contact inhibition, and may play a role in coordinating the stress response. PAK2 also contributes to cancer cell invasion through a mechanism distinct from that of PAK1. It belongs to the group I PAKs, which contain a PBD (p21-binding domain) overlapping with an AID (autoinhibitory domain), a C-terminal catalytic domain, SH3 binding sites and a non-classical SH3 binding site for PIX (PAK-interacting exchange factor). PAKs are Rho family GTPase-regulated kinases that serve as important mediators in the function of Cdc42 (cell division cycle 42) and Rac. The PAK subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-496 4.27e-20

Catalytic domain of the Serine/Threonine Kinase, Protein Kinase C; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. PKCs are classified into three groups (classical, atypical, and novel) depending on their mode of activation and the structural characteristics of their regulatory domain. PKCs undergo three phosphorylations in order to take mature forms. In addition, classical PKCs depend on calcium, DAG (1,2-diacylglycerol), and in most cases, phosphatidylserine (PS) for activation. Novel PKCs are calcium-independent, but require DAG and PS for activity, while atypical PKCs only require PS. PKCs phosphorylate and modify the activities of a wide variety of cellular proteins including receptors, enzymes, cytoskeletal proteins, transcription factors, and other kinases. They play a central role in signal transduction pathways that regulate cell migration and polarity, proliferation, differentiation, and apoptosis. Also included in this subfamily are the PKC-like proteins, called PKNs. The PKC subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine kinase, Calcium/calmodulin-dependent protein kinase Type I gamma; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. CaMKs are multifunctional calcium and calmodulin (CaM) stimulated STKs involved in cell cycle regulation. The CaMK family includes CaMKI, CaMKII, CaMKIV, and CaMK kinase (CaMKK). In vertebrates, there are four CaMKI proteins encoded by different genes (alpha, beta, gamma, and delta), each producing at least one variant. CaMKs contain an N-terminal catalytic domain and a C-terminal regulatory domain that harbors a CaM binding site. CaMKI proteins are monomeric and they play pivotal roles in the nervous system, including long-term potentiation, dendritic arborization, neurite outgrowth, and the formation of spines, synapses, and axons. In addition, they may be involved in osteoclast differentiation and bone resorption. The CaMKI-gamma subfamily is part of a larger superfamily that includes the catalytic domains of other protein kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

295-529 5.12e-20

Catalytic domain of Transforming Growth Factor beta Receptor-like Serine/Threonine Kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. This subfamily is composed of receptors for the TGFbeta family of secreted signaling molecules including TGFbeta, bone morphogenetic proteins (BMPs), activins, growth and differentiation factors (GDFs), and anti-Mullerian hormone, among others. These receptors contain an extracellular domain that binds ligands, a single transmembrane (TM) region, and a cytoplasmic catalytic kinase domain. There are two types of TGFbeta receptors included in this subfamily, I and II, that play different roles in signaling. For signaling to occur, the ligand first binds to the high-affinity type II receptor, which is followed by the recruitment of the low-affinity type I receptor to the complex and its activation through trans-phosphorylation by the type II receptor. The active type I receptor kinase starts intracellular signaling to the nucleus by phosphorylating SMAD proteins. Type I receptors contain an additional domain located between the TM and kinase domains called the the GS domain, which contains the activating phosphorylation site and confers preference for specific SMAD proteins. Different ligands interact with various combinations of types I and II receptors to elicit a specific signaling pathway. Activins primarily signal through combinations of ACVR1b/ALK7 and ACVR2a/b; myostatin and GDF11 through TGFbR1/ALK4 and ACVR2a/b; BMPs through ACVR1/ALK1 and BMPR2; and TGFbeta through TGFbR1 and TGFbR2. The TGFbR-like subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

271-477 5.36e-20

Catalytic domain of the Serine/Threonine Kinase, Fungal Cyclin-Dependent protein Kinase (CDK), Bypass UAS Requirement 1, and similar proteins; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. BUR1, also called SGV1, is a yeast CDK that is functionally equivalent to mammalian CDK9. It associates with the cyclin BUR2. BUR genes were orginally identified in a genetic screen as factors involved in general transcription. The BUR1/BUR2 complex phosphorylates the C-terminal domain of RNA polymerase II. In addition, this complex regulates histone modification by phosporylating Rad6 and mediating the association of the Paf1 complex with chromatin. CDKs belong to a large family of STKs that are regulated by their cognate cyclins. Together, they are involved in the control of cell-cycle progression, transcription, and neuronal function. The BUR1 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine kinases, Receptor Interacting Protein 4 and similar proteins; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. This subfamily is composed of RIP4, ankyrin (ANK) repeat and kinase domain containing 1 (ANKK1), and similar proteins, all of which harbor C-terminal ANK repeats. RIP4, also called Protein Kinase C-associated kinase (PKK), regulates keratinocyte differentiation and cutaneous inflammation. It activates NF-kappaB and is important in the survival of diffuse large B-cell lymphoma cells. The ANKK1 protein, also called PKK2, has not been studied extensively. The ANKK1 gene, located less than 10kb downstream of the D2 dopamine receptor (DRD2) locus, is altered in the Taq1 A1 polymorphism, which is related to a reduced DRD2 binding affinity and consequently, to mental disorders. The RIP4-like subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-488 6.91e-20

Catalytic domain of the Serine/Threonine Kinase, Myosin Light Chain Kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. MLCK phosphorylates myosin regulatory light chain and controls the contraction of all muscle types. In vertebrates, different MLCKs function in smooth (MLCK1), skeletal (MLCK2), and cardiac (MLCK3) muscles. A fourth protein, MLCK4, has also been identified through comprehensive genome analysis although it has not been biochemically characterized. The MLCK1 gene expresses three transcripts in a cell-specific manner: a short MLCK1 which contains three immunoglobulin (Ig)-like and one fibronectin type III (FN3) domains, PEVK and actin-binding regions, and a kinase domain near the C-terminus; a long MLCK1 containing six additional Ig-like domains at the N-terminus compared to the short MLCK1; and the C-terminal Ig module. MLCK2, MLCK3, and MLCK4 share a simpler domain architecture of a single kinase domain near the C-terminus and the absence of Ig-like or FN3 domains. The MLCK subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

293-488 7.16e-20

Catalytic domain of the Serine/Threonine Kinase, PCTAIRE-3 kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. PCTAIRE-3 shows a restricted pattern of expression and is present in brain, kidney, and intestine. It is elevated in Alzheimer's disease (AD) and has been shown to associate with paired helical filaments (PHFs) and stimulate Tau phosphorylation. As AD progresses, phosphorylated Tau aggregates and forms PHFs, which leads to the formation of neurofibrillary tangles. In human glioma cells, PCTAIRE-3 induces cell cycle arrest and cell death. PCTAIRE-3 shares sequence similarity with Cyclin-Dependent Kinases (CDKs), which belong to a large family of STKs that are regulated by their cognate cyclins. Together, CDKs and cyclins are involved in the control of cell-cycle progression, transcription, and neuronal function. The PCTAIRE-3 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Cyclin-Dependent protein Kinase 1 from higher eukaryotes; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. CDK1 is also called Cell division control protein 2 (Cdc2) or p34 protein kinase, and is regulated by cyclins A, B, and E. The CDK1/cyclin A complex controls G2 phase entry and progression. CDK1/cyclin A2 has also been implicated as an important regulator of S phase events. The CDK1/cyclin B complex is critical for G2 to M phase transition. It induces mitosis by activating nuclear enzymes that regulate chromatin condensation, nuclear membrane degradation, mitosis-specific microtubule and cytoskeletal reorganization. CDK1 also associates with cyclin E and plays a role in the entry into S phase. CDK1 transcription is stable throughout the cell cycle but is modulated in some pathological conditions. It may play a role in regulating apoptosis under these conditions. In breast cancer cells, HER2 can mediate apoptosis by inactivating CDK1. Activation of CDK1 may contribute to HIV-1 induced apoptosis as well as neuronal apoptosis in neurodegenerative diseases. CDKs belong to a large family of STKs that are regulated by their cognate cyclins. Together, they are involved in the control of cell-cycle progression, transcription, and neuronal function. The CDK1 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Yeast Sps1/Ste20-related Kinase 4; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. YSK4 is a putative MAPKKK, whose mammalian gene has been isolated. MAPKKKs phosphorylate and activate MAPK kinases, which in turn phosphorylate and activate MAPKs during signaling cascades that are important in mediating cellular responses to extracellular signals. The YSK4 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-534 7.59e-20

Catalytic domain of Mitogen-Activated Protein (MAP)/Extracellular signal-Regulated Kinase (ERK) Kinase Kinase 3-like Serine/Threonine Kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. This subfamily is composed of MEKK3, MEKK2, and related proteins; all contain an N-terminal PB1 domain, which mediates oligomerization, and a C-terminal catalytic domain. MEKK2 and MEKK3 are MAPK kinase kinases (MAPKKKs or MKKK) that activate MEK5 (also called MKK5), which activates ERK5. The ERK5 cascade plays roles in promoting cell proliferation, differentiation, neuronal survival, and neuroprotection. MEKK3 plays an essential role in embryonic angiogenesis and early heart development. MEKK2 and MEKK3 can also activate the MAPKs, c-Jun N-terminal kinase (JNK) and p38, through their respective MAPKKs. The MEKK3-like subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Apoptosis signal-regulating kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Members of this subfamily are mitogen-activated protein kinase (MAPK) kinase kinases (MAPKKKs or MKKKs) and include ASK1, ASK2, and MAPKKK15. ASK1 (also called MAPKKK5) functions in the c-Jun N-terminal kinase (JNK) and p38 MAPK signaling pathways by directly activating their respective MAPKKs, MKK4/MKK7 and MKK3/MKK6. It plays important roles in cytokine and stress responses, as well as in reactive oxygen species-mediated cellular responses. ASK1 is implicated in various diseases mediated by oxidative stress including inschemic heart disease, hypertension, vessel injury, brain ischemia, Fanconi anemia, asthma, and pulmonary edema, among others. ASK2 (also called MAPKKK6) functions only in a heteromeric complex with ASK1, and can activate ASK1 by direct phosphorylation. The function of MAPKKK15 is still unknown. The ASK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

173-277 9.52e-20

N-terminal Src homology 2 (SH2) domain found in Zeta-chain-associated protein kinase 70 (ZAP-70) and Spleen tyrosine kinase (Syk) proteins; ZAP-70 and Syk comprise a family of hematopoietic cell specific protein tyrosine kinases (PTKs) that are required for antigen and antibody receptor function. ZAP-70 is expressed in T and natural killer (NK) cells and Syk is expressed in B cells, mast cells, polymorphonuclear leukocytes, platelets, macrophages, and immature T cells. They are required for the proper development of T and B cells, immune receptors, and activating NK cells. They consist of two N-terminal Src homology 2 (SH2) domains and a C-terminal kinase domain separated from the SH2 domains by a linker or hinge region. Phosphorylation of both tyrosine residues within the Immunoreceptor Tyrosine-based Activation Motifs (ITAM; consensus sequence Yxx[LI]x(7,8)Yxx[LI]) by the Src-family PTKs is required for efficient interaction of ZAP-70 and Syk with the receptor subunits and for receptor function. ZAP-70 forms two phosphotyrosine binding pockets, one of which is shared by both SH2 domains. In Syk the two SH2 domains do not form such a phosphotyrosine-binding site. The SH2 domains here are believed to function independently. In addition, the two SH2 domains of Syk display flexibility in their relative orientation, allowing Syk to accommodate a greater variety of spacing sequences between the ITAM phosphotyrosines and singly phosphorylated non-classical ITAM ligands. This model contains the N-terminus SH2 domains of both Syk and Zap70. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

288-532 1.00e-19

Pseudokinase (repeat 1) domain of the Protein Tyrosine Kinase, Janus kinase 3; Jak3 is expressed only in hematopoietic cells. It binds the shared receptor subunit, common gamma chain and thus, is essential in the signaling of cytokines that use it such as IL-2, IL-4, IL-7, IL-9, IL-15, and IL-21. Jak3 is important in lymphoid development and myeloid cell differentiation. Inactivating mutations in Jak3 have been reported in humans with severe combined immunodeficiency (SCID). Jak3 is a cytoplasmic (or nonreceptor) PTK containing an N-terminal FERM domain, followed by a Src homology 2 (SH2) domain, a pseudokinase domain, and a C-terminal tyr kinase domain. The pseudokinase domain shows similarity to tyr kinases but lacks crucial residues for catalytic activity and ATP binding. It modulates the kinase activity of the C-terminal catalytic domain. Jaks are activated by autophosphorylation upon cytokine-induced receptor aggregation, and subsequently trigger downstream signaling events such as the phosphorylation of signal transducers and activators of transcription (STATs). The Jak3 subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

335-542 1.03e-19

Pseudokinase domain of the membrane Guanylate Cyclase receptor, GC-2D; The pseudokinase domain shows similarity to protein kinases but lacks crucial residues for catalytic activity and/or ATP binding. GC-2D is allso called Retinal Guanylyl Cyclase 1 (RETGC-1) or Rod Outer Segment membrane Guanylate Cyclase (ROS-GC). It is found in the photoreceptors of the retina where it anchors the reciprocal feedback loop between calcium and cGMP, which regulates the dark, light, and recovery phases in phototransduction. It is also found in other sensory neurons and may be a universal transduction component that plays a role in the perception of all senses. Membrane (or particulate) GCs consist of an extracellular ligand-binding domain, a single transmembrane region, and an intracellular tail that contains a PK-like domain, an amphiphatic region and a catalytic GC domain that catalyzes the conversion of GTP into cGMP and pyrophosphate. Membrane GCs act as receptors that transduce an extracellular signal to the intracellular production of cGMP, which has been implicated in many processes including cell proliferation, phototransduction, and muscle contractility, through its downstream effectors such as PKG. The PK-like domain of GCs functions as a negative regulator of the catalytic GC domain and may also act as a docking site for interacting proteins such as GC-activating proteins. The GC-2D subfamily is part of a larger superfamily that includes the catalytic domains of protein serine/threonine kinases, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

292-532 1.08e-19

Pseudokinase domain of Integrin Linked Kinase; The pseudokinase domain shows similarity to protein kinases but lacks crucial residues for catalytic activity. ILK contains N-terminal ankyrin repeats, a Pleckstrin Homology (PH) domain, and a C-terminal pseudokinase domain. It is a component of the IPP (ILK/PINCH/Parvin) complex that couples beta integrins to the actin cytoskeleton, and plays important roles in cell adhesion, spreading, invasion, and migration. ILK was initially thought to be an active kinase despite the lack of key conserved residues because of in vitro studies showing that it can phosphorylate certain protein substrates. However, in vivo experiments in Caenorhabditis elegans, Drosophila melanogaster, and mice (ILK-null and knock-in) proved that ILK is not an active kinase. In addition to actin cytoskeleton regulation, ILK also influences the microtubule network and mitotic spindle orientation. The pseudokinase domain of ILK binds several adaptor proteins including the parvins and paxillin. The ILK subfamily is part of a larger superfamily that includes the catalytic domains of protein serine/threonine kinases, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

293-488 1.19e-19

Catalytic domain of the Serine/Threonine Kinase, PCTAIRE-1 kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. PCTAIRE-1 is expressed ubiquitously and is localized in the cytoplasm. Its kinase activity is cell cycle dependent and peaks at the S and G2 phases. PCTAIRE-1 is highly expressed in the brain and may play a role in regulating neurite outgrowth. It can also associate with Trap (Tudor repeat associator with PCTAIRE-2), a physiological partner of PCTAIRE-2; with p11, a small dimeric protein with similarity to S100; and with 14-3-3 proteins, mediators of phosphorylation-dependent interactions in many different proteins. PCTAIRE-1 shares sequence similarity with Cyclin-Dependent Kinases (CDKs), which belong to a large family of STKs that are regulated by their cognate cyclins. Together, CDKs and cyclins are involved in the control of cell-cycle progression, transcription, and neuronal function. The PCTAIRE-1 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinases, Cyclin-Dependent protein Kinase 2 and 3; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. CDK2 is regulated by cyclin E or cyclin A. Upon activation by cyclin E, it phosphorylates the retinoblastoma (pRb) protein which activates E2F mediated transcription and allows cells to move into S phase. The CDK2/cyclin A complex plays a role in regulating DNA replication. CDK2, together with CDK4, also regulates embryonic cell proliferation. Despite these important roles, mice deleted for the cdk2 gene are viable and normal except for being sterile. This may be due to compensation provided by CDK1 (also called Cdc2), which can also bind cyclin E and drive the G1 to S phase transition. CDK3 is regulated by cyclin C and it phosphorylates pRB specifically during the G0/G1 transition. This phosphorylation is required for cells to exit G0 efficiently and enter the G1 phase. CDKs belong to a large family of STKs that are regulated by their cognate cyclins. Together, they are involved in the control of cell-cycle progression, transcription, and neuronal function. The CDK2/3 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Cell Cycle-Related Kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. CCRK was previously called p42. It is a Cyclin-Dependent Kinase (CDK)-Activating Kinase (CAK) which is essential for the activation of CDK2. It is indispensable for cell growth and has been implicated in the progression of glioblastoma multiforme. In the heart, a splice variant of CCRK with a different C-terminal half is expressed; this variant promotes cardiac cell growth and survival and is significantly down-regulated during the development of heart failure. The CCRK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Src homology 2 domain found in Growth factor receptor-bound protein 2 (Grb2) and similar proteins; The adaptor proteins here include homologs Grb2 in humans, Sex muscle abnormal protein 5 (Sem-5) in Caenorhabditis elegans, and Downstream of receptor kinase (drk) in Drosophila melanogaster. They are composed of one SH2 and two SH3 domains. Grb2/Sem-5/drk regulates the Ras pathway by linking the tyrosine kinases to the Ras guanine nucleotide releasing protein Sos, which converts Ras to the active GTP-bound state. The SH2 domain of Grb2/Sem-5/drk binds class II phosphotyrosyl peptides while its SH3 domain binds to Sos and Sos-derived, proline-rich peptides. Besides it function in Ras signaling, Grb2 is also thought to play a role in apoptosis. Unlike most SH2 structures in which the peptide binds in an extended conformation (such that the +3 peptide residue occupies a hydrophobic pocket in the protein, conferring a modest degree of selectivity), Grb2 forms several hydrogen bonds via main chain atoms with the side chain of +2 Asn. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

173-265 1.93e-19

Src homology 2 (SH2) domain found in Carboxyl-Terminal Src Kinase (Csk); Both the C-terminal Src kinase (CSK) and CSK-homologous kinase (CHK) are members of the CSK-family of protein tyrosine kinases. These proteins suppress activity of Src-family kinases (SFK) by selectively phosphorylating the conserved C-terminal tail regulatory tyrosine by a similar mechanism. CHK is also capable of inhibiting SFKs by a non-catalytic mechanism that involves binding of CHK to SFKs to form stable protein complexes. The unphosphorylated form of SFKs is inhibited by CSK and CHK by a two-step mechanism. The first step involves the formation of a complex of SFKs with CSK/CHK with the SFKs in the complex are inactive. The second step, involves the phosphorylation of the C-terminal tail tyrosine of SFKs, which then dissociates and adopt an inactive conformation. The structural basis of how the phosphorylated SFKs dissociate from CSK/CHK to adopt the inactive conformation is not known. The inactive conformation of SFKs is stabilized by two intramolecular inhibitory interactions: (a) the pYT:SH2 interaction in which the phosphorylated C-terminal tail tyrosine (YT) binds to the SH2 domain, and (b) the linker:SH3 interaction of which the SH2-kinase domain linker binds to the SH3 domain. SFKs are activated by multiple mechanisms including binding of the ligands to the SH2 and SH3 domains to displace the two inhibitory intramolecular interactions, autophosphorylation, and dephosphorylation of YT. By selective phosphorylation and the non-catalytic inhibitory mechanism CSK and CHK are able to inhibit the active forms of SFKs. CSK and CHK are regulated by phosphorylation and inter-domain interactions. They both contain SH3, SH2, and kinase domains separated by the SH3-SH2 connector and SH2 kinase linker, intervening segments separating the three domains. They lack a conserved tyrosine phosphorylation site in the kinase domain and the C-terminal tail regulatory tyrosine phosphorylation site. The CSK SH2 domain is crucial for stabilizing the kinase domain in the active conformation. A disulfide bond here regulates CSK kinase activity. The subcellular localization and activity of CSK are regulated by its SH2 domain. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

281-494 2.06e-19

Catalytic domain of the dual-specificity Protein Kinase, Mitogen-activated protein Kinase Kinase 4; PKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine (ST) or tyrosine residues on protein substrates. MKK4 is a dual-specificity PK that phosphorylates and activates the downstream targets, c-Jun N-terminal kinase (JNK) and p38 MAPK, on specific threonine and tyrosine residues. JNK and p38 are collectively known as stress-activated MAPKs, as they are activated in response to a variety of environmental stresses and pro-inflammatory cytokines. Their activation is associated with the induction of cell death. Mice deficient in MKK4 die during embryogenesis and display anemia, severe liver hemorrhage, and abnormal hepatogenesis. MKK4 may also play roles in the immune system and in cardiac hypertrophy. It plays a major role in cancer as a tumor and metastasis suppressor. Under certain conditions, MKK4 is pro-oncogenic. The MKK4 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Protein Serine/Threonine Kinase, Never In Mitosis gene A (NIMA)-related kinase 3; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Nek3 is primarily localized in the cytoplasm and shows no cell cycle-dependent changes in its activity. It is present in the axons of neurons and affects morphogenesis and polarity through its regulation of microtubule acetylation. Nek3 modulates the signaling of the prolactin receptor through its activation of Vav2 and contributes to prolactin-mediated motility of breast cancer cells. It is one in a family of 11 different Neks (Nek1-11) that are involved in cell cycle control. The Nek family is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

287-504 2.16e-19

Catalytic subunit of the Serine/Threonine Kinase, cAMP-dependent protein kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. The inactive PKA holoenzyme is a heterotetramer composed of two phosphorylated and active catalytic subunits with a dimer of regulatory (R) subunits. Activation is achieved through the binding of the important second messenger cAMP to the R subunits, which leads to the dissociation of PKA into the R dimer and two active subunits. PKA is present ubiquitously in cells and interacts with many different downstream targets. It plays a role in the regulation of diverse processes such as growth, development, memory, metabolism, gene expression, immunity, and lipolysis. The PKA subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine kinase, Calcium/calmodulin-dependent protein kinase Type I; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. CaMKs are multifunctional calcium and calmodulin (CaM) stimulated STKs involved in cell cycle regulation. There are several types of CaMKs including CaMKI, CaMKII, and CaMKIV. In vertebrates, there are four CaMKI proteins encoded by different genes (alpha, beta, gamma, and delta), each producing at least one variant. CaMKs contain an N-terminal catalytic domain and a C-terminal regulatory domain that harbors a CaM binding site. CaMKI proteins are monomeric and they play pivotal roles in the nervous system, including long-term potentiation, dendritic arborization, neurite outgrowth, and the formation of spines, synapses, and axons. In addition, they may be involved in osteoclast differentiation and bone resorption. The CaMKI subfamily is part of a larger superfamily that includes the catalytic domains of other protein kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Ste20-Like Kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. SLK promotes apoptosis through apoptosis signal-regulating kinase 1 (ASK1) and the mitogen-activated protein kinase (MAPK) p38. It acts as a MAPK kinase kinase by phosphorylating ASK1, resulting in the phosphorylation of p38. SLK also plays a role in mediating actin reorganization. It is part of a microtubule-associated complex that is targeted at adhesion sites, and is required in focal adhesion turnover and in regulating cell migration. The SLK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

291-487 2.82e-19

Catalytic domain of Fungal Pat1-like Serine/Threonine kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. This subfamily is composed of Schizosaccharomyces pombe Pat1 (also called Ran1), Saccharomyces cerevisiae VHS1 and KSP1, and similar fungal STKs. Pat1 blocks Mei2, an RNA-binding protein which is indispensable in the initiation of meiosis. Pat1 is inactivated and Mei2 activated, which initiates meiosis, under nutrient-deprived conditions through a signaling cascade involving Ste11. Meiosis induced by Pat1 inactivation may show different characteristics than normal meiosis including aberrant positioning of centromeres. VHS1 was identified in a screen for suppressors of cell cycle arrest at the G1/S transition, while KSP1 may be involved in regulating PRP20, which is required for mRNA export and maintenance of nuclear structure. The Pat1-like subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-540 2.88e-19

Catalytic domain of cyclin G-Associated Kinase-like proteins; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. This subfamily includes cyclin G-Associated Kinase (GAK), Drosophila melanogaster Numb-Associated Kinase (NAK)-like proteins, and similar protein kinases. GAK plays regulatory roles in clathrin-mediated membrane trafficking, the maintenance of centrosome integrity and chromosome congression, neural patterning, survival of neurons, and immune responses. NAK plays a role in asymmetric cell division through its association with Numb. It also regulates the localization of Dlg, a protein essential for septate junction formation. The GAK-like subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-495 3.37e-19

Catalytic domain of the Serine/Threonine Kinase, Classical Protein Kinase C beta; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. The PKC beta isoforms (I and II), generated by alternative splicing of a single gene, are preferentially activated by hyperglycemia-induced DAG (1,2-diacylglycerol) in retinal tissues. This is implicated in diabetic microangiopathy such as ischemia, neovascularization, and abnormal vasodilator function. PKC-beta also plays an important role in VEGF signaling. In addition, glucose regulates proliferation in retinal endothelial cells via PKC-betaI. PKC-beta is also being explored as a therapeutic target in cancer. It contributes to tumor formation and is involved in the tumor host mechanisms of inflammation and angiogenesis. PKCs are classified into three groups (classical, atypical, and novel) depending on their mode of activation and the structural characteristics of their regulatory domain. PKCs undergo three phosphorylations in order to take mature forms. In addition, cPKCs depend on calcium, DAG, and in most cases, phosphatidylserine (PS) for activation. The cPKC-beta subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinases, Chlamydomonas reinhardtii FA2 and similar proteins; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Chlamydomonas reinhardtii FA2 was discovered in a genetic screen for deflagellation-defective mutants. It is essential for basal-body/centriole-associated microtubule severing, and plays a role in cell cycle progression. No cellular function has yet been ascribed to CNK4. The Chlamydomonas reinhardtii FA2-like subfamily belongs to the (NIMA)-related kinase (Nek) family, which includes seven different Chlamydomonas Neks (CNKs 1-6 and Fa2). This subfamily contains FA2 and CNK4. The Nek family is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine kinase, Tousled-Like Kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. TLKs play important functions during the cell cycle and are implicated in chromatin remodeling, DNA replication and repair, and mitosis. They phosphorylate and regulate Anti-silencing function 1 protein (Asf1), a histone H3/H4 chaperone that helps facilitate the assembly of chromatin following DNA replication during S phase. TLKs also phosphorylate the H3 histone tail and are essential in transcription. Vertebrates contain two subfamily members, TLK1 and TLK2. The TLK subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

287-496 4.39e-19

Catalytic domain of PRKX-like Protein Serine/Threonine Kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Members of this group include human PRKX (X chromosome-encoded protein kinase), Drosophila DC2, and similar proteins. PRKX is present in many tissues including fetal and adult brain, kidney, and lung. The PRKX gene is located in the Xp22.3 subregion and has a homolog called PRKY on the Y chromosome. An abnormal interchange between PRKX aand PRKY leads to the sex reversal disorder of XX males and XY females. PRKX is implicated in granulocyte/macrophage lineage differentiation, renal cell epithelial migration, and tubular morphogenesis in the developing kidney. The PRKX-like subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

288-532 4.76e-19

Pseudokinase (repeat 1) domain of the Protein Tyrosine Kinase, Janus kinase 1; Jak1 is widely expressed in many tissues. Many cytokines are dependent on Jak1 for signaling, including those that use the shared receptor subunits, common gamma chain (IL-2, IL-4, IL-7, IL-9, IL-15, IL-21) and gp130 (IL-6, IL-11, oncostatin M, G-CSF, and IFNs, among others). The many varied interactions of Jak1 and its ubiquitous expression suggest many biological roles. Jak1 is important in neurological development, as well as in lymphoid development and function. It also plays a role in the pathophysiology of cardiac hypertrophy and heart failure. A mutation in the ATP-binding site of Jak1 was identified in a human uterine leiomyosarcoma cell line, resulting in defective cytokine induction and antigen presentation, thus allowing the tumor to evade the immune system. Jak1 is a cytoplasmic (or nonreceptor) PTK containing an N-terminal FERM domain, followed by a Src homology 2 (SH2) domain, a pseudokinase domain, and a C-terminal tyr kinase domain. The pseudokinase domain shows similarity to tyr kinases but lacks crucial residues for catalytic activity and ATP binding. It modulates the kinase activity of the C-terminal catalytic domain. The Jak1 subfamily is part of a larger superfamily that includes the catalytic domains of other kinases such as serine/threonine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

286-478 4.85e-19

Catalytic domain of the Serine/Threonine kinase, eukaryotic translation Initiation Factor 2-Alpha Kinase 3 or PKR-like Endoplasmic Reticulum Kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. PERK (or EIF2AK3) is a type-I ER transmembrane protein containing a luminal domain bound with the chaperone BiP under unstressed conditions and a cytoplasmic catalytic kinase domain. In response to the accumulation of misfolded or unfolded proteins in the ER, PERK is activated through the release of BiP, allowing it to dimerize and autophosphorylate. It functions as the central regulator of translational control during the Unfolded Protein Response (UPR) pathway. In addition to the eIF-2 alpha subunit, PERK also phosphorylates Nrf2, a leucine zipper transcription factor which regulates cellular redox status and promotes cell survival during the UPR. EIF2AKs phosphorylate the alpha subunit of eIF-2, resulting in the downregulation of protein synthesis. The PERK subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

288-531 5.04e-19

Catalytic domain of fungal Pek1-like dual-specificity Mitogen-Activated Protein Kinase Kinases; PKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine (ST) or tyrosine residues on protein substrates. Members of this group include the MAPKKs Pek1/Skh1 from Schizosaccharomyces pombe and MKK2 from Saccharomyces cerevisiae, and related proteins. Both fission yeast Pek1 and baker's yeast MKK2 are components of the cell integrity MAPK pathway. In fission yeast, Pek1 phosphorylates and activates Pmk1/Spm1 and is regulated by the MAPKK kinase Mkh1. In baker's yeast, the pathway involves the MAPK Slt2, the MAPKKs MKK1 and MKK2, and the MAPKK kinase Bck1. The cell integrity MAPK cascade is activated by multiple stress conditions, and is essential in cell wall construction, morphogenesis, cytokinesis, and ion homeostasis. MAPK signaling pathways are important mediators of cellular responses to extracellular signals. The MAPKK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

304-544 5.71e-19

Pseudokinase domain, repeat 1, of eukaryotic translation Initiation Factor 2-Alpha Kinase 4 or General Control Non-derepressible-2; The pseudokinase domain shows similarity to protein kinases but lacks crucial residues for catalytic activity. EIF2AKs phosphorylate the alpha subunit of eIF-2, resulting in the overall downregulation of protein synthesis. eIF-2 phosphorylation is induced in response to cellular stresses including virus infection, heat shock, nutrient deficiency, and the accummulation of unfolded proteins, among others. There are four distinct kinases that phosphorylate eIF-2 and control protein synthesis under different stress conditions: GCN2, protein kinase regulated by RNA (PKR), heme-regulated inhibitor kinase (HRI), and PKR-like endoplasmic reticulum kinase (PERK). GCN2 is activated by amino acid or serum starvation and UV irradiation. It induces GCN4, a transcriptional activator of amino acid biosynthetic genes, leading to increased production of amino acids under amino acid-deficient conditions. In serum-starved cells, GCN2 activation induces translation of the stress-responsive transcription factor ATF4, while under UV stress, GCN2 triggers transcriptional rescue via NF-kappaB signaling. GCN2 contains an N-terminal RWD, a degenerate kinase-like (repeat 1), the catalytic kinase (repeat 2), a histidyl-tRNA synthetase (HisRS)-like, and a C-terminal ribosome-binding and dimerization (RB/DD) domains. The degenerate pseudokinase domain of GCN2 may function as a regulatory domain. The GCN2 subfamily is part of a larger superfamily that includes the catalytic domains of serine/threonine kinases, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Myosin Light Chain Kinase 3; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. MLCK3 (or MYLK3) phosphorylates myosin regulatory light chain 2 and controls the contraction of cardiac muscles. It is expressed specifically in both the atrium and ventricle of the heart and its expression is regulated by the cardiac protein Nkx2-5. MLCK3 plays an important role in cardiogenesis by regulating the assembly of cardiac sarcomeres, the repeating contractile unit of striated muscle. MLCK3 contains a single kinase domain near the C-terminus and a unique N-terminal half, and unlike MLCK1/2, it does not appear to be regulated by Ca2+/calmodulin. The MLCK3 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

286-495 1.01e-18

Catalytic domain of the Serine/Threonine Kinase, Classical Protein Kinase C alpha; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. PKC-alpha is expressed in many tissues and is associated with cell proliferation, apoptosis, and cell motility. It plays a role in the signaling of the growth factors PDGF, VEGF, EGF, and FGF. Abnormal levels of PKC-alpha have been detected in many transformed cell lines and several human tumors. In addition, PKC-alpha is required for HER2 dependent breast cancer invasion. PKCs are classified into three groups (classical, atypical, and novel) depending on their mode of activation and the structural characteristics of their regulatory domain. PKCs undergo three phosphorylations in order to take mature forms. In addition, cPKCs depend on calcium, DAG (1,2-diacylglycerol), and in most cases, phosphatidylserine (PS) for activation. The cPKC-alpha subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

169-262 1.12e-18

Src homology 2 (SH2) domain found in the Fyn-related kinase (Frk); Frk is a member of the Src non-receptor type tyrosine kinase family of proteins. The Frk subfamily is composed of Frk/Rak and Iyk/Bsk/Gst. It is expressed primarily epithelial cells. Frk is a nuclear protein and may function during G1 and S phase of the cell cycle and suppress growth. Unlike the other Src members it lacks a glycine at position 2 of SH4 which is important for addition of a myristic acid moiety that is involved in targeting Src PTKs to cellular membranes. FRK and SHB exert similar effects when overexpressed in rat phaeochromocytoma (PC12) and beta-cells, where both induce PC12 cell differentiation and beta-cell proliferation. Under conditions that cause beta-cell degeneration these proteins augment beta-cell apoptosis. The FRK-SHB responses involve FAK and insulin receptor substrates (IRS) -1 and -2. Frk has been demonstrated to interact with retinoblastoma protein. Frk regulates PTEN protein stability by phosphorylating PTEN, which in turn prevents PTEN degradation. Frk also plays a role in regulation of embryonal pancreatic beta cell formation. Frk has a unique N-terminal domain, an SH3 domain, an SH2 domain, a kinase domain and a regulatory tail, as do the other members of the family. Like the other members of the Src family the SH2 domain in addition to binding the target, also plays an autoinhibitory role by binding to its activation loop. The tryosine involved is at the same site as the tyrosine involved in the autophosphorylation of Src. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

169-262 1.23e-18

Src homology 2 (SH2) domain found in the Src oncogene at 42A (Src42); Src42 is a member of the Src non-receptor type tyrosine kinase family of proteins. The integration of receptor tyrosine kinase-induced RAS and Src42 signals by Connector eNhancer of KSR (CNK) as a two-component input is essential for RAF activation in Drosophila. Src42 is present in a wide variety of organisms including: California sea hare, pea aphid, yellow fever mosquito, honey bee, Panamanian leafcutter ant, and sea urchin. Src42 has a unique N-terminal domain, an SH3 domain, an SH2 domain, a kinase domain and a regulatory tail, as do the other members of the family. Like the other members of the Src family the SH2 domain in addition to binding the target, also plays an autoinhibitory role by binding to its C-terminal tail. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

Catalytic domain of the Serine/Threonine kinase, Unc-51-like kinase 2; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. The ATG1/ULK complex is conserved from yeast to humans and it plays a critical role in the initiation of autophagy, the intracellular system that leads to the lysosomal degradation of cellular components and their recycling into basic metabolic units. ULK2 is ubiquitously expressed and is essential in autophagy induction. It displays partially redundant functions with ULK1 and is able to compensate for the loss of ULK1 in non-selective autophagy. It also displays neuron-specific functions and is important in axon development. The ULK2 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

GC-C binds and is activated by the intestinal hormones, guanylin (GN) and uroguanylin (UGN), which are secreted after salty meals to inhibit sodium absorption and induce the secretion of chloride, bicarbonate, and water. GN and UGN are also present in the kidney, where they induce increased salt and water secretion. This prevents the development of hypernatremia and hypervolemia after ingestion of high amounts of salt. Membrane (or particulate) GCs consist of an extracellular ligand-binding domain, a single transmembrane region, and an intracellular tail that contains a PK-like domain, an amphiphatic region and a catalytic GC domain that catalyzes the conversion of GTP into cGMP and pyrophosphate. Membrane GCs act as receptors that transduce an extracellular signal to the intracellular production of cGMP, which has been implicated in many processes including cell proliferation, phototransduction, and muscle contractility, through its downstream effectors such as PKG. The PK-like domain of GCs functions as a negative regulator of the catalytic GC domain and may also act as a docking site for interacting proteins such as GC-activating proteins. The GC-C subfamily is part of a larger superfamily that includes the catalytic domains of protein serine/threonine kinases, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

296-486 2.14e-18

Catalytic domain of Microtubule-associated serine/threonine (MAST) kinase-like proteins; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. This subfamily includes MAST kinases, MAST-like (MASTL) kinases (also called greatwall kinase or Gwl), and fungal kinases with similarity to Saccharomyces cerevisiae Rim15 and Schizosaccharomyces pombe cek1. MAST kinases contain an N-terminal domain of unknown function, a central catalytic domain, and a C-terminal PDZ domain that mediates protein-protein interactions. MASTL kinases carry only a catalytic domain which contains a long insert relative to other kinases. The fungal kinases in this subfamily harbor other domains in addition to a central catalytic domain, which like in MASTL, also contains an insert relative to MAST kinases. Rim15 contains a C-terminal signal receiver (REC) domain while cek1 contains an N-terminal PAS domain. MAST kinases are cytoskeletal associated kinases of unknown function that are also expressed at neuromuscular junctions and postsynaptic densities. MASTL/Gwl is involved in the regulation of mitotic entry, mRNA stabilization, and DNA checkpoint recovery. The fungal proteins Rim15 and cek1 are involved in the regulation of meiosis and mitosis, respectively. The MAST-like kinase subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine kinase, Calcium/calmodulin-dependent protein kinase Type I alpha; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. CaMKs are multifunctional calcium and calmodulin (CaM) stimulated STKs involved in cell cycle regulation. The CaMK family includes CaMKI, CaMKII, CaMKIV, and CaMK kinase (CaMKK). In vertebrates, there are four CaMKI proteins encoded by different genes (alpha, beta, gamma, and delta), each producing at least one variant. CaMKs contain an N-terminal catalytic domain and a C-terminal regulatory domain that harbors a CaM binding site. CaMKI proteins are monomeric and they play pivotal roles in the nervous system, including long-term potentiation, dendritic arborization, neurite outgrowth, and the formation of spines, synapses, and axons. In addition, they may be involved in osteoclast differentiation and bone resorption. The CaMKI-alpha subfamily is part of a larger superfamily that includes the catalytic domains of other protein kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of Kin1, Kin2, and simlar Serine/Threonine Kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. This subfamily is composed of yeast Kin1, Kin2, and similar proteins. Fission yeast Kin1 is a membrane-associated kinase that is involved in regulating cell surface cohesiveness during interphase. It also plays a role during mitosis, linking actomyosin ring assembly with septum synthesis and membrane closure to ensure separation of daughter cells. Budding yeast Kin1 and Kin2 act downstream of the Rab-GTPase Sec4 and are associated with the exocytic apparatus; they play roles in the secretory pathway. The Kin1/2 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, p38alpha Mitogen-Activated Protein Kinase (also called MAPK14); STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. p38alpha/MAPK14 is expressed in most tissues and is the major isoform involved in the immune and inflammatory response. It is the central p38 MAPK involved in myogenesis. It plays a role in regulating cell cycle check-point transition and promoting cell differentiation. p38alpha also regulates cell proliferation and death through crosstalk with the JNK pathway. Its substrates include MAPK activated protein kinase 2 (MK2), MK5, and the transcription factors ATF2 and Mitf. p38 kinases MAPKs, serving as important mediators of cellular responses to extracellular signals. They are activated by the MAPK kinases MKK3 and MKK6, which in turn are activated by upstream MAPK kinase kinases including TAK1, ASK1, and MLK3, in response to cellular stresses or inflammatory cytokines. The p38alpha subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-476 2.69e-18

Catalytic domain of the yeast Serine/Threonine Kinase, Kin4; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Kin4 is a central component of the spindle position checkpoint (SPOC), which monitors spindle position and regulates the mitotic exit network (MEN). Kin4 associates with spindle pole bodies in mother cells to inhibit MEN signaling and delay mitosis until the anaphase nucleus is properly positioned along the mother-bud axis. Kin4 activity is regulated by both the bud neck-associated kinase Elm1 and protein phosphatase 2A. The Kin4 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Cyclin-Dependent protein Kinase 5; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. CDK5 is unusual in that it is regulated by non-cyclin proteins, p35 and p39. It is highly expressed in the nervous system and is critical in normal neural development and function. It plays a role in neuronal migration and differentiation, and is also important in synaptic plasticity and learning. CDK5 also participates in protecting against cell death and promoting angiogenesis. Impaired CDK5 activity is implicated in Alzheimer's disease, amyotrophic lateral sclerosis, Parkinson's disease, Huntington's disease and acute neuronal injury. CDKs belong to a large family of STKs that are regulated by their cognate cyclins. Together, they are involved in the control of cell-cycle progression, transcription, and neuronal function. The CDK5 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Protein Kinase superfamily; The PK superfamily contains the large family of typical PKs that includes serine/threonine kinases (STKs), protein tyrosine kinases (PTKs), and dual-specificity PKs that phosphorylate both serine/threonine and tyrosine residues of target proteins, as well as pseudokinases that lack crucial residues for catalytic activity and/or ATP binding. It also includes phosphoinositide 3-kinases (PI3Ks), aminoglycoside 3'-phosphotransferases (APHs), choline kinase (ChoK), Actin-Fragmin Kinase (AFK), and the atypical RIO and Abc1p-like protein kinases. These proteins catalyze the transfer of the gamma-phosphoryl group from ATP to their target substrates; these include serine/threonine/tyrosine residues in proteins for typical or atypical PKs, the 3-hydroxyl of the inositol ring of D-myo-phosphatidylinositol (PtdIns) or its derivatives for PI3Ks, the 4-hydroxyl of PtdIns for PI4Ks, and other small molecule substrates for APH/ChoK and similar proteins such as aminoglycosides, macrolides, choline, ethanolamine, and homoserine.

Catalytic domain of the Serine/Threonine kinase, With No Lysine (WNK) kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. WNKs comprise a subfamily of STKs with an unusual placement of a catalytic lysine relative to all other protein kinases. They are critical in regulating ion balance and are thus, important components in the control of blood pressure. They are also involved in cell signaling, survival, proliferation, and organ development. WNKs are activated by hyperosmotic or low-chloride hypotonic stress and they function upstream of SPAK and OSR1 kinases, which regulate the activity of cation-chloride cotransporters through direct interaction and phosphorylation. There are four vertebrate WNKs which show varying expression patterns. WNK1 and WNK2 are widely expressed while WNK3 and WNK4 show a more restricted expression pattern. Because mutations in human WNK1 and WNK4 cause PseudoHypoAldosteronism type II (PHAII), characterized by hypertension (due to increased sodium reabsorption) and hyperkalemia (due to impaired renal potassium secretion), there are more studies conducted on these two proteins, compared to WNK2 and WNK3. The WNK subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Myosin Light Chain Kinase 1; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. MLCK1 (or MYLK1) phosphorylates myosin regulatory light chain and controls the contraction of smooth muscles. The MLCK1 gene expresses three transcripts in a cell-specific manner: a short MLCK1 which contains three immunoglobulin (Ig)-like and one fibronectin type III (FN3) domains, PEVK and actin-binding regions, and a kinase domain near the C-terminus followed by a regulatory segment containing an autoinhibitory Ca2+/calmodulin binding site; a long MLCK1 containing six additional Ig-like domains at the N-terminus compared to the short MLCK1; and the C-terminal Ig module which results in the expression of telokin in phasic smooth muscles, leading to Ca2+ desensitization by cyclic nucleotides of smooth muscle force. MLCK1 is also responsible for myosin regulatory light chain phosphorylation in nonmuscle cells and may play a role in regulating myosin II ATPase activity. The MLCK1 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

296-480 5.08e-18

Catalytic domain of the Serine/Threonine Kinase, Activin Type II Receptor; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. ACVR2 belongs to a group of receptors for the TGFbeta family of secreted signaling molecules that includes TGFbeta, bone morphogenetic proteins (BMPs), activins, growth and differentiation factors (GDFs), and anti-Mullerian hormone, among others. These receptors contain an extracellular domain that binds ligands, a single transmembrane region, and a cytoplasmic catalytic kinase domain. Type II receptors, such as ACVR2, are high-affinity receptors which bind ligands, autophosphorylate, as well as trans-phosphorylate and activate low-affinity type I receptors. ACVR2 acts primarily as the receptors for activins, nodal, myostatin, GDF11, and a subset of BMPs. ACVR2 signaling impacts many cellular and physiological processes including reproductive and gonadal functions, myogenesis, bone remodeling and tooth development, kidney organogenesis, apoptosis, fibrosis, inflammation, and neurogenesis. Vertebrates contain two ACVR2 proteins, ACVR2a (or ActRIIA) and ACVR2b (or ActRIIB). The ACVR2 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-486 5.38e-18

Catalytic domain of the Serine/Threonine Kinase, Doublecortin-like kinase 2 (also called Doublecortin-like and CAM kinase-like 2); STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. DCKL2 (or DCAMKL2) belongs to the doublecortin (DCX) family of proteins which are involved in neuronal migration, neurogenesis, and eye receptor development, among others. Family members typically contain tandem doublecortin (DCX) domains at the N-terminus; DCX domains can bind microtubules and serve as protein-interaction platforms. In addition, DCKL2 contains a serine, threonine, and proline rich domain (SP) and a C-terminal kinase domain with similarity to CAMKs. DCKL2 has been shown to interact with tubulin, JIP1/2, JNK, neurabin 2, and actin. It is associated with the terminal segments of axons and dendrites, and may function as a phosphorylation-dependent switch to control microtubule dynamics in neuronal growth cones. The DCKL2 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

287-531 5.47e-18

Catalytic domain of the dual-specificity Protein Kinase, Mitogen-activated protein Kinase Kinase 5; PKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine (ST) or tyrosine residues on protein substrates. MKK5 (also called MEK5) is a dual-specificity PK that phosphorylates its downstream target, extracellular signal-regulated kinase 5 (ERK5), on specific threonine and tyrosine residues. MKK5 is activated by MEKK2 and MEKK3 in response to mitogenic and stress stimuli. The ERK5 cascade promotes cell proliferation, differentiation, neuronal survival, and neuroprotection. This cascade plays an essential role in heart development. Mice deficient in either ERK5 or MKK5 die around embryonic day 10 due to cardiovascular defects including underdevelopment of the myocardium. In addition, MKK5 is associated with metastasis and unfavorable prognosis in prostate cancer. The MKK5 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

The catalytic domain of the Serine/Threonine Kinase, Glycogen Synthase Kinase 3; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. GSK3 is a mutifunctional kinase involved in many cellular processes including cell division, proliferation, differentiation, adhesion, and apoptosis. In plants, GSK3 plays a role in the response to osmotic stress. In Caenorhabditis elegans, it plays a role in regulating normal oocyte-to-embryo transition and response to oxidative stress. In Chlamydomonas reinhardtii, GSK3 regulates flagellar length and assembly. In mammals, there are two isoforms, GSK3alpha and GSK3beta, which show both distinct and redundant functions. The two isoforms differ mainly in their N-termini. They are both involved in axon formation and in Wnt signaling.They play distinct roles in cardiogenesis, with GSKalpha being essential in cardiomyocyte survival, and GSKbeta regulating heart positioning and left-right symmetry. GSK3beta was first identified as a regulator of glycogen synthesis, but has since been determined to play other roles. It regulates the degradation of beta-catenin and IkB. Beta-catenin is the main effector of Wnt, which is involved in normal haematopoiesis and stem cell function. IkB is a central inhibitor of NF-kB, which is critical in maintaining leukemic cell growth. GSK3beta is enriched in the brain and is involved in regulating neuronal signaling pathways. It is implicated in the pathogenesis of many diseases including Type II diabetes, obesity, mood disorders, Alzheimer's disease, osteoporosis, and some types of cancer, among others. The GSK3 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

169-262 6.62e-18

Src homology 2 (SH2) domain in lymphocyte cell kinase (Lck); Lck is a member of the Src non-receptor type tyrosine kinase family of proteins. It is expressed in the brain, T-cells, and NK cells. The unique domain of Lck mediates its interaction with two T-cell surface molecules, CD4 and CD8. It associates with their cytoplasmic tails on CD4 T helper cells and CD8 cytotoxic T cells to assist signaling from the T cell receptor (TCR) complex. When the T cell receptor is engaged by the specific antigen presented by MHC, Lck phosphorylase the intracellular chains of the CD3 and zeta-chains of the TCR complex, allowing ZAP-70 to bind them. Lck then phosphorylates and activates ZAP-70, which in turn phosphorylates Linker of Activated T cells (LAT), a transmembrane protein that serves as a docking site for proteins including: Shc-Grb2-SOS, PI3K, and phospholipase C (PLC). The tyrosine phosphorylation cascade culminates in the intracellular mobilization of a calcium ions and activation of important signaling cascades within the lymphocyte, including the Ras-MEK-ERK pathway, which goes on to activate certain transcription factors such as NFAT, NF-kappaB, and AP-1. These transcription factors regulate the production cytokines such as Interleukin-2 that promote long-term proliferation and differentiation of the activated lymphocytes. The N-terminal tail of Lck is myristoylated and palmitoylated and it tethers the protein to the plasma membrane of the cell. Lck also contains a SH3 domain, a SH2 domain, and a C-terminal tyrosine kinase domain. Lck has 2 phosphorylation sites, the first an autophosphorylation site that is linked to activation of the protein and the second which is phosphorylated by Csk, which inhibits it. Lck is also inhibited by SHP-1 dephosphorylation and by Cbl ubiquitin ligase, which is part of the ubiquitin-mediated pathway. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

292-534 7.80e-18

Catalytic domain of the Serine/Threonine Kinase, Thousand-and-One Amino acids 3; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. TAO3 is also known as JIK (c-Jun N-terminal kinase inhibitory kinase) or KFC (kinase from chicken). It specifically activates JNK, presumably by phosphorylating and activating MKK4/MKK7. In Saccharomyces cerevisiae, TAO3 is a component of the RAM (regulation of Ace2p activity and cellular morphogenesis) signaling pathway. TAO3 is upregulated in retinal ganglion cells after axotomy, and may play a role in apoptosis. TAO proteins possess mitogen-activated protein kinase (MAPK) kinase kinase activity. MAPK signaling cascades are important in mediating cellular responses to extracellular signals. The TAO3 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

295-479 8.23e-18

N-terminal Catalytic domain of Class III myosin-like Serine/Threonine Kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Class III myosins are motor proteins with an N-terminal kinase catalytic domain and a C-terminal actin-binding motor domain. Class III myosins are present in the photoreceptors of invertebrates and vertebrates and in the auditory hair cells of mammals. The kinase domain of myosin III can phosphorylate several cytoskeletal proteins, conventional myosin regulatory light chains, and can autophosphorylate the C-terminal motor domain. Myosin III may play an important role in maintaining the structural integrity of photoreceptor cell microvilli. It may also function as a cargo carrier during light-dependent translocation, in photoreceptor cells, of proteins such as transducin and arrestin. The Drosophila class III myosin, called NinaC (Neither inactivation nor afterpotential protein C), is critical in normal adaptation and termination of photoresponse. Vertebrates contain two isoforms of class III myosin, IIIA and IIIB. This subfamily also includes mammalian NIK-like embryo-specific kinase (NESK), Traf2- and Nck-interacting kinase (TNIK), and mitogen-activated protein kinase (MAPK) kinase kinase kinase 4/6. MAP4Ks are involved in some MAPK signaling pathways by activating a MAPK kinase kinase. MAPK signaling cascades are important in mediating cellular responses to extracellular signals. The class III myosin-like subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-475 8.62e-18

Catalytic domain of the Serine/Threonine kinase, Checkpoint kinase 1; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Chk1 is implicated in many major checkpoints of the cell cycle, providing a link between upstream sensors and the cell cycle engine. It plays an important role in DNA damage response and maintaining genomic stability. Chk1 acts as an effector of the sensor kinase, ATR (ATM and Rad3-related), a member of the PI3K family, which is activated upon DNA replication stress. Chk1 delays mitotic entry in response to replication blocks by inhibiting cyclin dependent kinase (Cdk) activity. In addition, Chk1 contributes to the function of centrosome and spindle-based checkpoints, inhibits firing of origins of DNA replication (Ori), and represses transcription of cell cycle proteins including cyclin B and Cdk1. The Chk1 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine kinase, Calcium/calmodulin-dependent protein kinase Type I beta; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. CaMKs are multifunctional calcium and calmodulin (CaM) stimulated STKs involved in cell cycle regulation. The CaMK family includes CaMKI, CaMKII, CaMKIV, and CaMK kinase (CaMKK). In vertebrates, there are four CaMKI proteins encoded by different genes (alpha, beta, gamma, and delta), each producing at least one variant. CaMKs contain an N-terminal catalytic domain and a C-terminal regulatory domain that harbors a CaM binding site. CaMKI proteins are monomeric and they play pivotal roles in the nervous system, including long-term potentiation, dendritic arborization, neurite outgrowth, and the formation of spines, synapses, and axons. In addition, they may be involved in osteoclast differentiation and bone resorption. The CaMKI-beta subfamily is part of a larger superfamily that includes the catalytic domains of other protein kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

287-534 1.00e-17

Catalytic domain of the Serine/Threonine kinase, Aurora-B kinase and similar proteins; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Aurora kinases are key regulators of mitosis and are essential for the accurate and equal division of genomic material from parent to daughter cells. Vertebrates contain at least 2 Aurora kinases (A and B); mammals contains a third Aurora kinase gene (C). This subfamily includes Aurora-B and Aurora-C. Aurora-B is most active at the transition during metaphase to the end of mitosis. It associates with centromeres, relocates to the midzone of the central spindle, and concentrates at the midbody during cell division. It is critical for accurate chromosomal segregation, cytokinesis, protein localization to the centrosome and kinetochore, correct microtubule-kinetochore attachments, and regulation of the mitotic checkpoint. Aurora-C is mainly expressed in meiotically dividing cells; it was originally discovered in mice as a testis-specific STK called Aie1. Both Aurora-B and -C are chromosomal passenger proteins that can form complexes with INCENP and survivin, and they may have redundant cellular functions. INCENP participates in the activation of Aurora-B in a two-step process: first by binding to form an intermediate state of activation and the phosphorylation of its C-terminal TSS motif to generate the fully active kinase. The Aurora-B subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

166-262 1.09e-17

Src homology 2 (SH2) domain found in Tec-like proteins; The Tec protein tyrosine kinase is the founding member of a family that includes Btk, Itk, Bmx, and Txk. The members have a PH domain, a zinc-binding motif, a SH3 domain, a SH2 domain, and a protein kinase catalytic domain. Btk is involved in B-cell receptor signaling with mutations in Btk responsible for X-linked agammaglobulinemia (XLA) in humans and X-linked immunodeficiency (xid) in mice. Itk is involved in T-cell receptor signaling. Tec is expressed in both T and B cells, and is thought to function in activated and effector T lymphocytes to induce the expression of genes regulated by NFAT transcription factors. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

Although PAK1 has been regarded mainly as a cytosolic protein, recent reports indicate that PAK1 also exists in significant amounts in the nucleus, where it is involved in transcription modulation and in cell cycle regulatory events. PAK1 is also involved in transformation and tumorigenesis. Its overexpression, hyperactivation and increased nuclear accumulation is correlated to breast cancer invasiveness and progression. Nuclear accumulation is also linked to tamoxifen resistance in breast cancer cells. PAK1 belongs to the group I PAKs, which contain a PBD (p21-binding domain) overlapping with an AID (autoinhibitory domain), a C-terminal catalytic domain, SH3 binding sites and a non-classical SH3 binding site for PIX (PAK-interacting exchange factor). PAKs are Rho family GTPase-regulated kinases that serve as important mediators in the function of Cdc42 (cell division cycle 42) and Rac. The PAK subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

293-504 1.35e-17

Catalytic domain of the Serine/Threonine Kinase, PCTAIRE-2 kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. PCTAIRE-2 is specifically expressed in neurons in the central nervous system, mainly in terminally differentiated neurons. It associates with Trap (Tudor repeat associator with PCTAIRE-2) and could play a role in regulating mitochondrial function in neurons. PCTAIRE-2 shares sequence similarity with Cyclin-Dependent Kinases (CDKs), which belong to a large family of STKs that are regulated by their cognate cyclins. Together, CDKs and cyclins are involved in the control of cell-cycle progression, transcription, and neuronal function. The PCTAIRE-2 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-508 1.48e-17

Catalytic domain of the Serine/Threonine Kinases, Novel Protein Kinase C theta, delta, and similar proteins; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. PKC-theta is selectively expressed in T-cells and plays an important and non-redundant role in several aspects of T-cell biology. PKC-delta plays a role in cell cycle regulation and programmed cell death in many cell types. PKCs are classified into three groups (classical, atypical, and novel) depending on their mode of activation and the structural characteristics of their regulatory domain. nPKCs are calcium-independent, but require DAG (1,2-diacylglycerol) and phosphatidylserine (PS) for activity. There are four nPKC isoforms, delta, epsilon, eta, and theta. The nPKC-theta-like subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

169-265 1.54e-17

C-terminal Src homology 2 (SH2) domain found in Spleen tyrosine kinase (Syk) proteins; ZAP-70 and Syk comprise a family of hematopoietic cell specific protein tyrosine kinases (PTKs) that are required for antigen and antibody receptor function. ZAP-70 is expressed in T and natural killer (NK) cells and Syk is expressed in B cells, mast cells, polymorphonuclear leukocytes, platelets, macrophages, and immature T cells. They are required for the proper development of T and B cells, immune receptors, and activating NK cells. They consist of two N-terminal Src homology 2 (SH2) domains and a C-terminal kinase domain separated from the SH2 domains by a linker or hinge region. Phosphorylation of both tyrosine residues within the Immunoreceptor Tyrosine-based Activation Motifs (ITAM; consensus sequence Yxx[LI]x(7,8)Yxx[LI]) by the Src-family PTKs is required for efficient interaction of ZAP-70 and Syk with the receptor subunits and for receptor function. ZAP-70 forms two phosphotyrosine binding pockets, one of which is shared by both SH2 domains. In Syk the two SH2 domains do not form such a phosphotyrosine-binding site. The SH2 domains here are believed to function independently. In addition, the two SH2 domains of Syk display flexibility in their relative orientation, allowing Syk to accommodate a greater variety of spacing sequences between the ITAM phosphotyrosines and singly phosphorylated non-classical ITAM ligands. This model contains the C-terminus SH2 domains of Syk. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

Catalytic domain of the Serine/Threonine Kinase, Leucine-Rich Repeat Kinase 1; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. LRRK1 is one of two vertebrate LRRKs which show complementary expression in the brain. It can form heterodimers with LRRK2, and may influence the age of onset of LRRK2-associated Parkinson's disease. LRRKs are also classified as ROCO proteins because they contain a ROC (Ras of complex proteins)/GTPase domain followed by a COR (C-terminal of ROC) domain of unknown function. In addition, LRRKs contain a catalytic kinase domain and protein-protein interaction motifs including a WD40 domain, LRRs and ankyrin (ANK) repeats. LRRKs possess both GTPase and kinase activities, with the ROC domain acting as a molecular switch for the kinase domain, cycling between a GTP-bound state which drives kinase activity and a GDP-bound state which decreases the activity. The LRRK1 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Protein Serine/Threonine Kinase, p21-activated kinase 3; Serine/threonine kinases (STKs), p21-activated kinase (PAK) 3, catalytic (c) domain. STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. The PAK subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase. PAKs are Rho family GTPase-regulated kinases that serve as important mediators in the function of Cdc42 (cell division cycle 42) and Rac. PAKs from higher eukaryotes are classified into two groups (I and II), according to their biochemical and structural features. PAK3 belongs to group I. Group I PAKs contain a PBD (p21-binding domain) overlapping with an AID (autoinhibitory domain), a C-terminal catalytic domain, SH3 binding sites and a non-classical SH3 binding site for PIX (PAK-interacting exchange factor). PAK3 is highly expressed in the brain. It is implicated in neuronal plasticity, synapse formation, dendritic spine morphogenesis, cell cycle progression, neuronal migration, and apoptosis. Inactivating mutations in the PAK3 gene cause X-linked non-syndromic mental retardation, the severity of which depends on the site of the mutation.

Catalytic domain of the Serine/Threonine Kinase, Protein Kinase N; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. PKN has a C-terminal catalytic domain that is highly homologous to PKCs. Its unique N-terminal regulatory region contains antiparallel coiled-coil (ACC) domains. In mammals, there are three PKN isoforms from different genes (designated PKN-alpha, beta, and gamma), which show different enzymatic properties, tissue distribution, and varied functions. PKN can be activated by the small GTPase Rho, and by fatty acids such as arachidonic and linoleic acids. It is involved in many biological processes including cytokeletal regulation, cell adhesion, vesicle transport, glucose transport, regulation of meiotic maturation and embryonic cell cycles, signaling to the nucleus, and tumorigenesis. The PKN subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

168-262 3.17e-17

Src homology 2 (SH2) domain found in the Vav family; Vav proteins are involved in several processes that require cytoskeletal reorganization, such as the formation of the immunological synapse (IS), phagocytosis, platelet aggregation, spreading, and transformation. Vavs function as guanine nucleotide exchange factors (GEFs) for the Rho/Rac family of GTPases. Vav family members have several conserved motifs/domains including: a leucine-rich region, a leucine-zipper, a calponin homology (CH) domain, an acidic domain, a Dbl-homology (DH) domain, a pleckstrin homology (PH) domain, a cysteine-rich domain, 2 SH3 domains, a proline-rich region, and a SH2 domain. Vavs are the only known Rho GEFs that have both the DH/PH motifs and SH2/SH3 domains in the same protein. The leucine-rich helix-loop-helix (HLH) domain is thought to be involved in protein heterodimerization with other HLH proteins and it may function as a negative regulator by forming inactive heterodimers. The CH domain is usually involved in the association with filamentous actin, but in Vav it controls NFAT stimulation, Ca2+ mobilization, and its transforming activity. Acidic domains are involved in protein-protein interactions and contain regulatory tyrosines. The DH domain is a GDP-GTP exchange factor on Rho/Rac GTPases. The PH domain in involved in interactions with GTP-binding proteins, lipids and/or phosphorylated serine/threonine residues. The SH3 domain is involved in localization of proteins to specific sites within the cell interacting with protein with proline-rich sequences. The SH2 domain mediates a high affinity interaction with tyrosine phosphorylated proteins. There are three Vav mammalian family members: Vav1 which is expressed in the hematopoietic system, Vav2 and Vav3 are more ubiquitously expressed. The members here include insect and amphibian Vavs. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

294-535 4.36e-17

Catalytic domain of the Protein Serine/Threonine Kinase, Never In Mitosis gene A (NIMA)-related kinase 9; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Nek9, also called Nercc1, is primarily a cytoplasmic protein but can also localize in the nucleus. It is involved in modulating chromosome alignment and splitting during mitosis. It interacts with the gamma-tubulin ring complex and the Ran GTPase, and is implicated in microtubule organization. Nek9 associates with FACT (FAcilitates Chromatin Transcription) and modulates interphase progression. It also interacts with Nek6, and Nek7, during mitosis, resulting in their activation. Nek9 is one in a family of 11 different Neks (Nek1-11) that are involved in cell cycle control. The Nek family is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

321-476 5.07e-17

Catalytic domain of the Serine/Threonine Kinase, Phosphorylase kinase Gamma subunit; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Phosphorylase kinase (PhK) catalyzes the phosphorylation of inactive phosphorylase b to form the active phosphorylase a. It coordinates hormonal, metabolic, and neuronal signals to initiate the breakdown of glycogen stores, which enables the maintenance of blood-glucose homeostasis during fasting, and is also used as a source of energy for muscle contraction. PhK is one of the largest and most complex protein kinases, composed of a heterotetramer containing four molecules each of four subunit types: one catalytic (gamma) and three regulatory (alpha, beta, and delta). Each subunit has tissue-specific isoforms or splice variants. Vertebrates contain two isoforms of the gamma subunit (gamma 1 and gamma 2). The gamma subunit, when isolated, is constitutively active and does not require phosphorylation of the A-loop for activity. The regulatory subunits restrain this kinase activity until signals are received to relieve this inhibition. For example, the kinase is activated in response to hormonal stimulation, after autophosphorylation or phosphorylation by cAMP-dependent kinase of the alpha and beta subunits. The high-affinity binding of ADP to the beta subunit also stimulates kinase activity, whereas calcium relieves inhibition by binding to the delta (calmodulin) subunit. The PhKG subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

292-503 5.16e-17

Catalytic domain of PCTAIRE-like Serine/Threonine Kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. PCTAIRE-like proteins show unusual expression patterns with high levels in post-mitotic tissues, suggesting that they may be involved in regulating post-mitotic cellular events. They share sequence similarity with Cyclin-Dependent Kinases (CDKs), which belong to a large family of STKs that are regulated by their cognate cyclins. Together, CDKs and cyclins are involved in the control of cell-cycle progression, transcription, and neuronal function. The association of PCTAIRE-like proteins with cyclins has not been widely studied, although PFTAIRE-1 has been shown to function as a CDK which is regulated by cyclin D3 as well as the membrane-associated cyclin Y. The PCTAIRE-like subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

293-501 5.19e-17

Catalytic domain of Serine/Threonine Kinase 33; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. STK33 is highly expressed in the testis and is present in low levels in most tissues. It may be involved in spermatogenesis and organ ontogenesis. It interacts with and phosphorylates vimentin and may be involved in regulating intermediate filament cytoskeletal dynamics. Its role in promoting the cell viability of KRAS-dependent cancer cells is under debate; some studies have found STK33 to promote cancer cell viability, while other studies have found it to be non-essential. KRAS is the most commonly mutated human oncogene, thus, studies on the role of STK33 in KRAS mutant cancer cells are important. The STK33 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-478 5.59e-17

Catalytic domain of Cyclin-Dependent protein Kinase 4 and 6-like Serine/Threonine Kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. CDK4 and CDK6 partner with D-type cyclins to regulate the early G1 phase of the cell cycle. They are the first kinases activated by mitogenic signals to release cells from the G0 arrested state. CDK4 and CDK6 are both expressed ubiquitously, associate with all three D cyclins (D1, D2 and D3), and phosphorylate the retinoblastoma (pRb) protein. They are also regulated by the INK4 family of inhibitors which associate with either the CDK alone or the CDK/cyclin complex. CDK4 and CDK6 show differences in subcellular localization, sensitivity to some inhibitors, timing in activation, tumor selectivity, and possibly substrate profiles. Although CDK4 and CDK6 seem to show some redundancy, they also have discrete, nonoverlapping functions. CDK6 plays an important role in cell differentiation. CDKs belong to a large family of STKs that are regulated by their cognate cyclins. Together, they are involved in the control of cell-cycle progression, transcription, and neuronal function. The CDK4/6-like subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

158-258 5.61e-17

Src homology 2 domain found in Src-like adaptor proteins; SLAP belongs to the subfamily of adapter proteins that negatively regulate cellular signaling initiated by tyrosine kinases. It has a myristylated N-terminus, SH3 and SH2 domains with high homology to Src family tyrosine kinases, and a unique C-terminal tail, which is important for c-Cbl binding. SLAP negatively regulates platelet-derived growth factor (PDGF)-induced mitogenesis in fibroblasts and regulates F-actin assembly for dorsal ruffles formation. c-Cbl mediated SLAP inhibition towards actin remodeling. Moreover, SLAP enhanced PDGF-induced c-Cbl phosphorylation by SFK. In contrast, SLAP mitogenic inhibition was not mediated by c-Cbl, but it rather involved a competitive mechanism with SFK for PDGF-receptor (PDGFR) association and mitogenic signaling. Accordingly, phosphorylation of the Src mitogenic substrates Stat3 and Shc were reduced by SLAP. Thus, we concluded that SLAP regulates PDGFR signaling by two independent mechanisms: a competitive mechanism for PDGF-induced Src mitogenic signaling and a non-competitive mechanism for dorsal ruffles formation mediated by c-Cbl. SLAP is a hematopoietic adaptor containing Src homology (SH)3 and SH2 motifs and a unique carboxy terminus. Unlike c-Src, SLAP lacks a tyrosine kinase domain. Unlike c-Src, SLAP does not impact resorptive function of mature osteoclasts but induces their early apoptosis. SLAP negatively regulates differentiation of osteoclasts and proliferation of their precursors. Conversely, SLAP decreases osteoclast death by inhibiting activation of caspase 3. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

169-262 5.62e-17

Src homology 2 (SH2) domain found in HCK; HCK is a member of the Src non-receptor type tyrosine kinase family of proteins and is expressed in hemopoietic cells. HCK is proposed to couple the Fc receptor to the activation of the respiratory burst. It may also play a role in neutrophil migration and in the degranulation of neutrophils. It has two different translational starts that have different subcellular localization. HCK has been shown to interact with BCR gene, ELMO1 Cbl gene, RAS p21 protein activator 1, RASA3, Granulocyte colony-stimulating factor receptor, ADAM15 and RAPGEF1. Like the other members of the Src family the SH2 domain in addition to binding the target, also plays an autoinhibitory role by binding to its C-terminal tail. In general SH2 domains are involved in signal transduction. HCK has a unique N-terminal domain, an SH3 domain, an SH2 domain, a kinase domain and a regulatory tail, as do the other members of the family. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

294-488 5.83e-17

Catalytic domain of the Serine/Threonine Kinases, Bone Morphogenetic Protein and Anti-Muellerian Hormone Type II Receptors; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. BMPR2 and AMHR2 belong to a group of receptors for the TGFbeta family of secreted signaling molecules that includes TGFbeta, BMPs, activins, growth and differentiation factors (GDFs), and AMH, among others. These receptors contain an extracellular domain that binds ligands, a single transmembrane region, and a cytoplasmic catalytic kinase domain. Type II receptors are high-affinity receptors which bind ligands, autophosphorylate, as well as trans-phosphorylate and activate low-affinity type I receptors. BMPR2 and AMHR2 act primarily as a receptor for BMPs and AMH, respectively. BMPs induce bone and cartilage formation, as well as regulate tooth, kidney, skin, hair, haematopoietic, and neuronal development. Mutations in BMPR2A is associated with familial pulmonary arterial hypertension. AMH is mainly responsible for the regression of Mullerian ducts during male sex differentiation. It is expressed exclusively by somatic cells of the gonads. Mutations in either AMH or AMHR2 cause persistent Mullerian duct syndrome (PMDS), a rare form of male pseudohermaphroditism characterized by the presence of Mullerian derivatives (ovary and tubes) in otherwise normally masculine males. The BMPR2/AMHR2 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine kinase, Calcium/calmodulin-dependent protein kinase Type II; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. CaMKs are multifunctional calcium and calmodulin (CaM) stimulated STKs involved in cell cycle regulation. There are several types of CaMKs including CaMKI, CaMKII, and CaMKIV. CaMKs contain an N-terminal catalytic domain followed by a regulatory domain that harbors a CaM binding site. In addition, CaMKII contains a C-terminal association domain that facilitates oligomerization. There are four CaMKII proteins (alpha, beta, gamma, delta) encoded by different genes; each gene undergoes alternative splicing to produce more than 30 isoforms. CaMKII-alpha and -beta are enriched in neurons while CaMKII-gamma and -delta are predominant in myocardium. CaMKII is a signaling molecule that translates upstream calcium and reactive oxygen species (ROS) signals into downstream responses that play important roles in synaptic function and cardiovascular physiology. It is a major component of the postsynaptic density and is critical in regulating synaptic plasticity including long-term potentiation. It is critical in regulating ion channels and proteins involved in myocardial excitation-contraction and excitation-transcription coupling. Excessive CaMKII activity promotes processes that contribute to heart failure and arrhythmias. The CaMKII subfamily is part of a larger superfamily that includes the catalytic domains of other protein kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Protein Serine/Threonine Kinase, Never In Mitosis gene A (NIMA)-related kinase 1; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Nek1 is associated with centrosomes throughout the cell cycle. It is involved in the formation of primary cilium and in the maintenance of centrosomes. It cycles through the nucleus and may be capable of relaying signals between the cilium and the nucleus. Nek1 is implicated in the development of polycystic kidney disease, which is characterized by benign polycystic tumors formed by abnormal overgrowth of renal epithelial cells. It appears also to be involved in DNA damage response, and may be important for both correct DNA damage checkpoint activation and DNA repair. Nek1 is one in a family of 11 different Neks (Nek1-11) that are involved in cell cycle control. The Nek family is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

173-250 7.44e-17

Src homology 2 domain found in SH2 domain-containing adapter proteins B, D, E, and F (SHB, SHD, SHE, SHF); SHB, SHD, SHE, and SHF are SH2 domain-containing proteins that play various roles throughout the cell. SHB functions in generating signaling compounds in response to tyrosine kinase activation. SHB contains proline-rich motifs, a phosphotyrosine binding (PTB) domain, tyrosine phosphorylation sites, and a SH2 domain. SHB mediates certain aspects of platelet-derived growth factor (PDGF) receptor-, fibroblast growth factor (FGF) receptor-, neural growth factor (NGF) receptor TRKA-, T cell receptor-, interleukin-2 (IL-2) receptor- and focal adhesion kinase- (FAK) signaling. SRC-like FYN-Related Kinase FRK/RAK (also named BSK/IYK or GTK) and SHB regulate apoptosis, proliferation and differentiation. SHB promotes apoptosis and is also required for proper mitogenicity, spreading and tubular morphogenesis in endothelial cells. SHB also plays a role in preventing early cavitation of embryoid bodies and reduces differentiation to cells expressing albumin, amylase, insulin and glucagon. SHB is a multifunctional protein that has difference responses in different cells under various conditions. SHE is expressed in heart, lung, brain, and skeletal muscle, while expression of SHD is restricted to the brain. SHF is mainly expressed in skeletal muscle, brain, liver, prostate, testis, ovary, small intestine, and colon. SHD may be a physiological substrate of c-Abl and may function as an adapter protein in the central nervous system. It is also thought to be involved in apoptotic regulation. SHD contains five YXXP motifs, a substrate sequence preferred by Abl tyrosine kinases, in addition to a poly-proline rich region and a C-terminal SH2 domain. SHE contains two pTry protein binding domains, protein interaction domain (PID) and a SH2 domain, followed by a glycine-proline rich region, all of which are N-terminal to the phosphotyrosine binding (PTB) domain. SHF contains four putative tyrosine phosphorylation sites and an SH2 domain. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

315-541 7.64e-17

Catalytic domain of the Dual-specificity protein kinase, Lymphokine-activated killer T-cell-originated protein kinase; Dual-specificity PKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine as well as tyrosine residues on protein substrates. TOPK, also called PDZ-binding kinase (PBK), is activated at the early stage of mitosis and plays a critical role in cytokinesis. It partly functions as a mitogen-activated protein kinase (MAPK) kinase and is capable of phosphorylating p38, JNK1, and ERK2. TOPK also plays a role in DNA damage sensing and repair through its phosphorylation of histone H2AX. It contributes to cancer development and progression by downregulating the function of tumor suppressor p53 and reducing cell-cycle regulatory proteins. TOPK is found highly expressed in breast and skin cancer cells. The TOPK subfamily is part of a larger superfamily that includes the catalytic domains of other protein kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

292-529 8.95e-17

Catalytic domain of the Serine/Threonine Kinases, Transforming Growth Factor beta Type I Receptor and Activin Type IB/IC Receptors; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. TGFbR1, also called Activin receptor-Like Kinase 5 (ALK5), functions as a receptor for TGFbeta and phoshorylates SMAD2/3. TGFbeta proteins are cytokines that regulate cell growth, differentiation, and survival, and are critical in the development and progression of many human cancers. Mutations in TGFbR1 (and TGFbR2) can cause aortic aneurysm disorders such as Loeys-Dietz and Marfan syndromes. ACVR1b (also called ALK4) and ACVR1c (also called ALK7) act as receptors for activin A and B, respectively. TGFbR1, ACVR1b, and ACVR1c belong to a group of receptors for the TGFbeta family of secreted signaling molecules that includes TGFbeta, bone morphogenetic proteins, activins, growth and differentiation factors, and anti-Mullerian hormone, among others. These receptors contain an extracellular domain that binds ligands, a single transmembrane (TM) region, and a cytoplasmic catalytic kinase domain. Type I receptors, like TGFbR1, ACVR1b, and ACVR1c, are low-affinity receptors that bind ligands only after they are recruited by the ligand/type II high-affinity receptor complex. Following activation, they start intracellular signaling to the nucleus by phosphorylating SMAD proteins. Type I receptors contain an additional domain located between the TM and kinase domains called the GS domain, which contains the activating phosphorylation site and confers preference for specific SMAD proteins. The TGFbR1 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

287-490 9.20e-17

Catalytic domain of the Serine/Threonine kinase, Per-ARNT-Sim (PAS) domain Kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. PASK (or PASKIN) is a nutrient and energy sensor and thus, plays an important role in maintaining cellular energy homeostasis. It coordinates the utilization of glucose in response to metabolic demand. It contains an N-terminal PAS domain which directly interacts and inhibits a C-terminal catalytic kinase domain. The PAS domain serves as a sensory module for different environmental signals such as light, redox state, and various metabolites. Binding of ligands to the PAS domain causes structural changes which leads to kinase activation and the phosphorylation of substrates to trigger the appropriate cellular response. The PASK subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

293-523 9.37e-17

Catalytic domain of the Serine/Threonine Kinase, PFTAIRE-2 kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. PFTAIRE-2 is also referred to as ALS2CR7 (amyotrophic lateral sclerosis 2 (juvenile) chromosome region candidate 7). It may be associated with amyotrophic lateral sclerosis 2 (ALS2), an autosomal recessive form of juvenile ALS. The function of PFTAIRE-2 is not yet known. It shares sequence similarity with Cyclin-Dependent Kinases (CDKs), which belong to a large family of STKs that are regulated by their cognate cyclins. Together, CDKs and cyclins are involved in the control of cell-cycle progression, transcription, and neuronal function. The PFTAIRE-2 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

293-536 1.00e-16

Catalytic domain of fungal Byr1-like dual-specificity Mitogen-activated protein Kinase Kinases; PKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine (ST) or tyrosine residues on protein substrates. Members of this group include the MAPKKs Byr1 from Schizosaccharomyces pombe, FUZ7 from Ustilago maydis, and related proteins. Byr1 phosphorylates its downstream target, the MAPK Spk1, and is regulated by the MAPKK kinase Byr2. The Spk1 cascade is pheromone-responsive and is essential for sporulation and sexual differentiation in fission yeast. FUZ7 phosphorylates and activates its target, the MAPK Crk1, which is required in mating and virulence in U. maydis. MAPK signaling pathways are important mediators of cellular responses to extracellular signals. The Byr-1 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-486 1.09e-16

Catalytic domain of the Serine/Threonine Kinase, Novel Protein Kinase C eta; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. PKC-eta is predominantly expressed in squamous epithelia, where it plays a crucial role in the signaling of cell-type specific differentiation. It is also expressed in pro-B cells and early-stage thymocytes, and acts as a key regulator in early B-cell development. PKC-eta increases glioblastoma multiforme (GBM) proliferation and resistance to radiation, and is being developed as a therapeutic target for the management of GBM. PKCs are classified into three groups (classical, atypical, and novel) depending on their mode of activation and the structural characteristics of their regulatory domain. nPKCs are calcium-independent, but require DAG (1,2-diacylglycerol) and phosphatidylserine (PS) for activity. The nPKC-eta subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinases, Thousand-and-One Amino acids proteins; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. TAO proteins possess mitogen-activated protein kinase (MAPK) kinase kinase activity. They activate the MAPKs, p38 and c-Jun N-terminal kinase (JNK), by phosphorylating and activating the respective MAP/ERK kinases (MEKs, also known as MKKs or MAPKKs), MEK3/MEK6 and MKK4/MKK7. MAPK signaling cascades are important in mediating cellular responses to extracellular signals. Vertebrates contain three TAO subfamily members, named TAO1, TAO2, and TAO3. The TAO subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

293-498 1.32e-16

Catalytic domain of the Serine/Threonine Kinase, Fungal Cyclin-Dependent protein Kinase Pho85; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Pho85 is a multifunctional CDK in yeast. It is regulated by 10 different cyclins (Pcls) and plays a role in G1 progression, cell polarity, phosphate and glycogen metabolism, gene expression, and in signaling changes in the environment. It is not essential for yeast viability and is the functional homolog of mammalian CDK5, which plays a role in central nervous system development. CDKs belong to a large family of STKs that are regulated by their cognate cyclins. Together, they are involved in the control of cell-cycle progression, transcription, and neuronal function. The Pho85 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

285-486 1.36e-16

Catalytic domain of the Serine/Threonine Kinase, Group II p21-activated kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Group II PAKs, also called non-conventional PAKs, include PAK4, PAK5, and PAK6. Group II PAKs contain PBD (p21-binding domain) and catalytic domains, but lack other motifs found in group I PAKs, such as an AID (autoinhibitory domain) and SH3 binding sites. Since group II PAKs do not contain an obvious AID, they may be regulated differently from group I PAKs. While group I PAKs interact with the SH3 containing proteins Nck, Grb2 and PIX, no such binding has been demonstrated for group II PAKs. Some known substrates of group II PAKs are also substrates of group I PAKs such as Raf, BAD, LIMK and GEFH1. Unique group II substrates include MARK/Par-1 and PDZ-RhoGEF. Group II PAKs play important roles in filopodia formation, neuron extension, cytoskeletal organization, and cell survival. PAKs are Rho family GTPase-regulated kinases that serve as important mediators in the function of Cdc42 (cell division cycle 42) and Rac. The PAK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Classical (or Conventional) Protein Kinase C; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. cPKCs are potent kinases for histones, myelin basic protein, and protamine. They depend on calcium, DAG (1,2-diacylglycerol), and in most cases, phosphatidylserine (PS) for activation. cPKCs contain a calcium-binding C2 region in their regulatory domain. There are four cPKC isoforms, named alpha, betaI, betaII, and gamma. PKC-gamma is mainly expressed in neuronal tissues. It plays a role in protection from ischemia. PKCs are classified into three groups (classical, atypical, and novel) depending on their mode of activation and the structural characteristics of their regulatory domain. The cPKC subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Novel Protein Kinase C delta; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. PKC-delta plays a role in cell cycle regulation and programmed cell death in many cell types. It slows down cell proliferation, inducing cell cycle arrest and enhancing cell differentiation. PKC-delta is also involved in the regulation of transcription as well as immune and inflammatory responses. It plays a central role in the genotoxic stress response that leads to DNA damaged-induced apoptosis. PKCs are classified into three groups (classical, atypical, and novel) depending on their mode of activation and the structural characteristics of their regulatory domain. nPKCs are calcium-independent, but require DAG (1,2-diacylglycerol) and phosphatidylserine (PS) for activity. The nPKC-delta subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

293-486 1.44e-16

C-terminal kinase domain of the Large Serine/Threonine Kinase and Rho Guanine Nucleotide Exchange Factor, Triple functional domain protein; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Triple functional domain protein (Trio), also called PTPRF-interacting protein, is a large multidomain protein containing a series of spectrin-like repeats, two each of RhoGEF and SH3 domains, an immunoglobulin-like (Ig) domain and a C-terminal kinase. Trio plays important roles in neuronal cell migration and axon guidance. It was originally identified as an interacting partner of the of the receptor-like tyrosine phosphatase (RPTP) LAR (leukocyte-antigen-related protein), a family of receptors that function in the signaling to the actin cytoskeleton during development. Trio functions as a GEF for Rac1, RhoG, and RhoA, and is involved in the regulation of lamellipodia formation, mediating Rac1-dependent cell spreading and migration. The Trio subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

172-250 2.54e-16

Src homology 2 (SH2) domain found in the Nck family; Nck proteins are adaptors that modulate actin cytoskeleton dynamics by linking proline-rich effector molecules to tyrosine kinases or phosphorylated signaling intermediates. There are two members known in this family: Nck1 (Nckalpha) and Nck2 (Nckbeta and Growth factor receptor-bound protein 4 (Grb4)). They are characterized by having 3 SH3 domains and a C-terminal SH2 domain. Nck1 and Nck2 have overlapping functions as determined by gene knockouts. Both bind receptor tyrosine kinases and other tyrosine-phosphorylated proteins through their SH2 domains. In addition they also bind distinct targets. Neuronal signaling proteins: EphrinB1, EphrinB2, and Disabled-1 (Dab-1) all bind to Nck-2 exclusively. And in the case of PDGFR, Tyr(P)751 binds to Nck1 while Tyr(P)1009 binds to Nck2. Nck1 and Nck2 have a role in the infection process of enteropathogenic Escherichia coli (EPEC). Their SH3 domains are involved in recruiting and activating the N-WASP/Arp2/3 complex inducing actin polymerization resulting in the production of pedestals, dynamic bacteria-presenting protrusions of the plasma membrane. A similar thing occurs in the vaccinia virus where motile plasma membrane projections are formed beneath the virus. Recently it has been shown that the SH2 domains of both Nck1 and Nck2 bind the G-protein coupled receptor kinase-interacting protein 1 (GIT1) in a phosphorylation-dependent manner. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

Src homology 2 (SH2) domain found in alpha2-chimerin and beta2-chimerin proteins; Chimerins are a family of phorbol ester- and diacylglycerol-responsive GTPase-activating proteins. Alpha1-chimerin (formerly known as n-chimerin) and alpha2-chimerin are alternatively spliced products of a single gene, as are beta1- and beta2-chimerin. alpha1- and beta1-chimerin have a relatively short N-terminal region that does not encode any recognizable domains, whereas alpha2- and beta2-chimerin both include a functional SH2 domain that can bind to phosphotyrosine motifs within receptors. All of the isoforms contain a GAP domain with specificity in vitro for Rac1 and a diacylglycerol (DAG)-binding C1 domain which allows them to translocate to membranes in response to DAG signaling and anchors them in close proximity to activated Rac. Other C1 domain-containing diacylglycerol receptors including: PKC, Munc-13 proteins, phorbol ester binding scaffolding proteins involved in Ca2+-stimulated exocytosis, and RasGRPs, diacylglycerol-activated guanine-nucleotide exchange factors (GEFs) for Ras and Rap1. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

331-486 3.04e-16

Catalytic domain of the Serine/Threonine kinase, Calmodulin Dependent Protein Kinase Kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. CaMKKs are upstream kinases of the CaM kinase cascade that phosphorylate and activate CaMKI and CamKIV. They may also phosphorylate other substrates including PKB and AMP-activated protein kinase (AMPK). Vertebrates contain two CaMKKs, CaMKK1 (or alpha) and CaMKK2 (or beta). CaMKK1 is involved in the regulation of glucose uptake in skeletal muscles. CaMKK2 is involved in regulating energy balance, glucose metabolism, adiposity, hematopoiesis, inflammation, and cancer. The CaMKK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

293-529 3.49e-16

Catalytic domain of the Serine/Threonine Kinase, Bone Morphogenetic Protein Type IA Receptor; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. BMPR1a, also called Activin receptor-Like Kinase 3 (ALK3), functions as a receptor for bone morphogenetic proteins (BMPs), which are involved in the regulation of cell proliferation, survival, differentiation, and apoptosis. BMPs are able to induce bone, cartilage, ligament, and tendon formation, and may play roles in bone diseases and tumors. Germline mutations in BMPR1a are associated with an increased risk to Juvenile Polyposis Syndrome, a hamartomatous disorder that may lead to gastrointestinal cancer. BMPR1a may also play an indirect role in the development of hematopoietic stem cells (HSCs) as osteoblasts are a major component of the HSC niche within the bone marrow. BMPR1a belongs to a group of receptors for the TGFbeta family of secreted signaling molecules that includes TGFbeta, BMPs, activins, growth and differentiation factors, and anti-Mullerian hormone, among others. These receptors contain an extracellular domain that binds ligands, a single transmembrane (TM) region, and a cytoplasmic catalytic kinase domain. Type I receptors, like BMPR1a, are low-affinity receptors that bind ligands only after they are recruited by the ligand/type II high-affinity receptor complex. Following activation, they start intracellular signaling to the nucleus by phosphorylating SMAD proteins. Type I receptors contain an additional domain located between the TM and kinase domains called the GS domain, which contains the activating phosphorylation site and confers preference for specific SMAD proteins. The BMPR1a subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

290-476 3.56e-16

Catalytic domain of the Serine/Threonine Kinase, SNF1-related kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. SNRK is a kinase highly expressed in testis and brain that is found inactive in cells that lack the LKB1 tumour suppressor protein kinase. The regulatory subunits STRAD and MO25 are required for LKB1 to activate SNRK. The SNRK mRNA is increased 3-fold when granule neurons are cultured in low potassium, and may thus play a role in the survival responses in these cells. In some vertebrates, a second SNRK gene (snrkb or snrk-1) has been sequenced and/or identified. Snrk-1 is expressed specifically in embryonic zebrafish vasculature; it plays an essential role in angioblast differentiation, maintenance, and migration. The SNRK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Cyclin-Dependent protein Kinase 12; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. CDK12 is also called Cdc2-related protein kinase 7 (CRK7) or Cdc2-related kinase arginine/serine-rich (CrkRS). It is a unique CDK that contains an RS domain, which is predominantly found in splicing factors. CDK12 is widely expressed in tissues. It interacts with cyclins L1 and L2, and plays roles in regulating transcription and alternative splicing. CDKs belong to a large family of STKs that are regulated by their cognate cyclins. Together, they are involved in the control of cell-cycle progression, transcription, and neuronal function. The CDK12 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Mitogen-activated protein kinase kinase kinase kinase 5; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. MAP4K5, also called germinal center kinase-related enzyme (GCKR), has been shown to activate the MAPK c-Jun N-terminal kinase (JNK). MAP4K5 also facilitates Wnt signaling in B cells, and may therefore be implicated in the control of cell fate, proliferation, and polarity. MAP4Ks are involved in some MAPK signaling pathways by activating a MAPK kinase kinase. Each MAPK cascade is activated either by a small GTP-binding protein or by an adaptor protein, which transmits the signal either directly to a MAP3K to start the triple kinase core cascade or indirectly through a mediator kinase, a MAP4K. Members of this subfamily contain an N-terminal catalytic domain and a C-terminal citron homology (CNH) regulatory domain. The MAP4K5 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

289-486 4.47e-16

C-terminal catalytic domain of the Serine/Threonine Kinase, Ribosomal S6 kinase 1 (also called Ribosomal protein S6 kinase alpha-1 or 90kDa ribosomal protein S6 kinase 1); STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. RSK1 is also called S6K-alpha-1, RPS6KA1, p90RSK1 or MAPK-activated protein kinase 1a (MAPKAPK-1a). It is a component of the insulin transduction pathway, regulating the function of IRS1. It also interacts with PKA and promotes its inactivation. RSK1 is one of four RSK isoforms (RSK1-4) from distinct genes present in vertebrates. RSKs contain an N-terminal kinase domain (NTD) from the AGC family and a C-terminal kinase domain (CTD) from the CAMK family. They are activated by signaling inputs from extracellular regulated kinase (ERK) and phosphoinositide dependent kinase 1 (PDK1). ERK phosphorylates and activates the CTD of RSK, serving as a docking site for PDK1, which phosphorylates and activates the NTD, which in turn phosphorylates all known RSK substrates. RSKs act as downstream effectors of mitogen-activated protein kinase (MAPK) and play key roles in mitogen-activated cell growth, differentiation, and survival. The RSK1 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Mitogen-Activated Protein Kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. MAPKs serve as important mediators of cellular responses to extracellular signals. They control critical cellular functions including differentiation, proliferation, migration, and apoptosis. They are also implicated in the pathogenesis of many diseases including multiple types of cancer, stroke, diabetes, and chronic inflammation. Typical MAPK pathways involve a triple kinase core cascade comprising of the MAPK, which is phosphorylated and activated by a MAPK kinase (MAP2K or MKK), which itself is phosphorylated and activated by a MAPK kinase kinase (MAP3K or MKKK). Each cascade is activated either by a small GTP-binding protein or by an adaptor protein, which transmits the signal either directly to a MAP3K to start the triple kinase core cascade or indirectly through a mediator kinase, a MAP4K. There are three typical MAPK subfamilies: Extracellular signal-Regulated Kinase (ERK), c-Jun N-terminal Kinase (JNK), and p38. Some MAPKs are atypical in that they are not regulated by MAP2Ks. These include MAPK4, MAPK6, NLK, and ERK7. The MAPK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

290-488 6.54e-16

Catalytic domain of the Serine/Threonine Kinase, Death-Associated Protein Kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. DAPKs mediate cell death and act as tumor suppressors. They are necessary to induce cell death and their overexpression leads to death-associated changes including membrane blebbing, cell rounding, and formation of autophagic vesicles. Vertebrates contain three subfamily members with different domain architecture, localization, and function. DAPK1 is the prototypical member of the subfamily and is also simply referred to as DAPK. DAPK2 is also called DAPK-related protein 1 (DRP-1), while DAPK3 has also been named DAP-like kinase (DLK) and zipper-interacting protein kinase (ZIPk). These proteins are ubiquitously expressed in adult tissues, are capable of cross talk with each other, and may act synergistically in regulating cell death. The DAPK subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

288-479 6.98e-16

Catalytic domain of the Serine/Threonine Kinases, Activin Type I Receptor and Activin receptor-Like Kinase 1; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. ACVR1, also called Activin receptor-Like Kinase 2 (ALK2), and ALK1 act as receptors for bone morphogenetic proteins (BMPs) and they activate SMAD1/5/8. ACVR1 is widely expressed while ALK1 is limited mainly to endothelial cells. The specificity of BMP binding to type I receptors is affected by type II receptors. ACVR1 binds BMP6/7/9/10 and can also bind anti-Mullerian hormone (AMH) in the presence of AMHR2. ALK1 binds BMP9/10 as well as TGFbeta in endothelial cells. A missense mutation in the GS domain of ACVR1 causes fibrodysplasia ossificans progressiva, a complex and disabling disease characterized by congenital skeletal malformations and extraskeletal bone formation. ACVR1 belongs to a group of receptors for the TGFbeta family of secreted signaling molecules that includes TGFbeta, BMPs, activins, growth and differentiation factors, and AMH, among others. These receptors contain an extracellular domain that binds ligands, a single transmembrane (TM) region, and a cytoplasmic catalytic kinase domain. Type I receptors, like ACVR1 and ALK1, are low-affinity receptors that bind ligands only after they are recruited by the ligand/type II high-affinity receptor complex. Following activation, they start intracellular signaling to the nucleus by phosphorylating SMAD proteins. Type I receptors contain an additional domain located between the TM and kinase domains called the GS domain, which contains the activating phosphorylation site and confers preference for specific SMAD proteins. The ACVR1 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-510 7.27e-16

Catalytic domain of testis-specific serine/threonine kinase 1, TSSK2, and similar proteins; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. TSSK proteins are almost exclusively expressed postmeiotically in the testis and play important roles in spermatogenesis and/or spermiogenesis. There are five mammalian TSSK proteins which show differences in their localization and timing of expression. TSSK1 and TSSK2 are expressed specifically in meiotic and postmeiotic spermatogenic cells, respectively. TSSK2 is localized in the sperm neck, equatorial segment, and mid-piece of the sperm tail. Both TSSK1 and TSSK2 phosphorylate their common substrate TSKS (testis-specific-kinase-substrate). TSSK1/TSSK2 double knock-out mice are sterile without manifesting other defects, making these kinases viable targets for male contraception. The TSSK1/2-like subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Cyclin-Dependent protein Kinase 10; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. CDK10, also called PISSLRE, is essential for cell growth and proliferation, and acts through the G2/M phase of the cell cycle. CDK10 has also been identified as an important factor in endocrine therapy resistance in breast cancer. CDK10 silencing increases the transcription of c-RAF and the activation of the p42/p44 MAPK pathway, which leads to antiestrogen resistance. Patients who express low levels of CDK10 relapse early on tamoxifen. CDKs belong to a large family of STKs that are regulated by their cognate cyclins. Together, they are involved in the control of cell-cycle progression, transcription, and neuronal function. The CDK10 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

293-486 8.83e-16

Catalytic domain of the Serine/Threonine kinase, Inhibitor of Nuclear Factor-KappaB Kinase (IKK) beta; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. IKKbeta is involved in the classical pathway of regulating Nuclear Factor-KappaB (NF-kB) proteins, a family of transcription factors which are critical in many cellular functions including inflammatory responses, immune development, cell survival, and cell proliferation, among others. The classical pathway regulates the majority of genes activated by NF-kB including those encoding cytokines, chemokines, leukocyte adhesion molecules, and anti-apoptotic factors. It involves NEMO (NF-kB Essential MOdulator)- and IKKbeta-dependent phosphorylation and degradation of the Inhibitor of NF-kB (IkB), which liberates NF-kB dimers (typified by the p50-p65 heterodimer) from an inactive IkB/dimeric NF-kB complex, enabling them to migrate to the nucleus where they regulate gene transcription. The IKKbeta subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Death-Associated Protein Kinase 1; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. DAPKs mediate cell death and act as tumor suppressors. They are necessary to induce cell death and their overexpression leads to death-associated changes including membrane blebbing, cell rounding, and formation of autophagic vesicles. Vertebrates contain three subfamily members with different domain architecture, localization, and function. DAPK1 is the prototypical member of the subfamily and is also simply referred to as DAPK. It is Ca2+/calmodulin (CaM)-regulated and actin-associated protein that contains an N-terminal kinase domain followed by an autoinhibitory CaM binding region and a large C-terminal extension with multiple functional domains including ankyrin (ANK) repeats, a cytoskeletal binding domain, a Death domain, and a serine-rich tail. Loss of DAPK1 expression, usually because of DNA methylation, is implicated in many tumor types. DAPK1 is highly abundant in the brain and has also been associated with neurodegeneration. The DAPK1 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Thousand-and-One Amino acids 1; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. TAO1 is sometimes referred to as prostate-derived sterile 20-like kinase 2 (PSK2). TAO1 activates the p38 MAPK through direct interaction with and activation of MEK3. TAO1 is highly expressed in the brain and may play a role in neuronal apoptosis. TAO1 interacts with the checkpoint proteins BubR1 and Mad2, and plays an important role in regulating mitotic progression, which is required for both chromosome congression and checkpoint-induced anaphase delay. TAO1 may play a role in protecting genomic stability. TAO proteins possess MAPK kinase kinase activity. MAPK signaling cascades are important in mediating cellular responses to extracellular signals. The TAO1 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

169-259 1.27e-15

Src homology 2 (SH2) domain found in tyrosine kinase sarcoma (Src); Src is a member of the Src non-receptor type tyrosine kinase family of proteins. Src is thought to play a role in the regulation of embryonic development and cell growth. Members here include v-Src and c-Src. v-Src lacks the C-terminal inhibitory phosphorylation site and is therefore constitutively active as opposed to normal cellular src (c-Src) which is only activated under certain circumstances where it is required (e.g. growth factor signaling). v-Src is an oncogene whereas c-Src is a proto-oncogene. c-Src consists of three domains, an N-terminal SH3 domain, a central SH2 domain and a tyrosine kinase domain. The SH2 and SH3 domains work together in the auto-inhibition of the kinase domain. The phosphorylation of an inhibitory tyrosine near the c-terminus of the protein produces a binding site for the SH2 domain which then facilitates binding of the SH3 domain to a polyproline site within the linker between the SH2 domain and the kinase domain. Binding of the SH3 domain inactivates the enzyme. This allows for multiple mechanisms for c-Src activation: dephosphorylation of the C-terminal tyrosine by a protein tyrosine phosphatase, binding of the SH2 domain by a competitive phospho-tyrosine residue, or competitive binding of a polyproline binding site to the SH3 domain. Unlike most other Src members Src lacks cysteine residues in the SH4 domain that undergo palmitylation. Serine and threonine phosphorylation sites have also been identified in the unique domains of Src and are believed to modulate protein-protein interactions or regulate catalytic activity. Alternatively spliced forms of Src, which contain 6- or 11-amino acid insertions in the SH3 domain, are expressed in CNS neurons. c-Src has a unique N-terminal domain, an SH3 domain, an SH2 domain, a kinase domain and a regulatory tail, as do the other members of the family. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

293-481 1.63e-15

Catalytic domain of Cyclin-Dependent protein Kinase 8-like Serine/Threonine Kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. This subfamily is composed of CDK8, CDC2L6, and similar proteins. CDK8 functions as a negative or positive regulator of transcription, depending on the scenario. Together with its regulator, cyclin C, it reversibly associates with the multi-subunit core Mediator complex, a cofactor that is involved in regulating RNA polymerase II-dependent transcription. CDC2L6 also associates with Mediator in complexes lacking CDK8. In VP16-dependent transcriptional activation, CDK8 and CDC2L6 exerts opposing effects by positive and negative regulation, respectively, in similar conditions. CDKs belong to a large family of STKs that are regulated by their cognate cyclins. Together, they are involved in the control of cell-cycle progression, transcription, and neuronal function. The CDK8-like subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

271-486 1.64e-15

C-terminal catalytic domain of the Serine/Threonine Kinase, Ribosomal S6 kinase 2 (also called 90kDa ribosomal protein S6 kinase 3 or Ribosomal protein S6 kinase alpha-3); STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. RSK2 is also called p90RSK3, RPS6KA3, S6K-alpha-3, or MAPK-activated protein kinase 1b (MAPKAPK-1b). RSK2 is expressed highly in the regions of the brain with high synaptic activity. It plays a role in the maintenance and consolidation of excitatory synapses. It is a specific modulator of phospholipase D in calcium-regulated exocytosis. Mutations in the RSK2 gene, RPS6KA3, cause Coffin-Lowry syndrome (CLS), a rare syndromic form of X-linked mental retardation characterized by growth and psychomotor retardation and skeletal abnormalities. RSK2 is one of four RSK isoforms (RSK1-4) from distinct genes present in vertebrates. RSKs contain an N-terminal kinase domain (NTD) from the AGC family and a C-terminal kinase domain (CTD) from the CAMK family. They are activated by signaling inputs from extracellular regulated kinase (ERK) and phosphoinositide dependent kinase 1 (PDK1). ERK phosphorylates and activates the CTD of RSK, serving as a docking site for PDK1, which phosphorylates and activates the NTD, which in turn phosphorylates all known RSK substrates. RSKs act as downstream effectors of mitogen-activated protein kinase (MAPK) and play key roles in mitogen-activated cell growth, differentiation, and survival. The RSK2 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

173-262 1.68e-15

C-terminal Src homology 2 (C-SH2) domain found in SH2 domain Phosphatases (SHP) proteins; The SH2 domain phosphatases (SHP-1, SHP-2/Syp, Drosophila corkscrew (csw), and Caenorhabditis elegans Protein Tyrosine Phosphatase (Ptp-2)) are cytoplasmic signaling enzymes. They are both targeted and regulated by interactions of their SH2 domains with phosphotyrosine docking sites. These proteins contain two SH2 domains (N-SH2, C-SH2) followed by a tyrosine phosphatase (PTP) domain, and a C-terminal extension. Shp1 and Shp2 have two tyrosyl phosphorylation sites in their C-tails, which are phosphorylated differentially by receptor and nonreceptor PTKs. Csw retains the proximal tyrosine and Ptp-2 lacks both sites. Shp-binding proteins include receptors, scaffolding adapters, and inhibitory receptors. Some of these bind both Shp1 and Shp2 while others bind only one. Most proteins that bind a Shp SH2 domain contain one or more immuno-receptor tyrosine-based inhibitory motifs (ITIMs): [SIVL]xpYxx[IVL]. Shp1 N-SH2 domain blocks the catalytic domain and keeps the enzyme in the inactive conformation, and is thus believed to regulate the phosphatase activity of SHP-1. Its C-SH2 domain is thought to be involved in searching for phosphotyrosine activators. The SHP2 N-SH2 domain is a conformational switch; it either binds and inhibits the phosphatase, or it binds phosphoproteins and activates the enzyme. The C-SH2 domain contributes binding energy and specificity, but it does not have a direct role in activation. Csw SH2 domain function is essential, but either SH2 domain can fulfill this requirement. The role of the csw SH2 domains during Sevenless receptor tyrosine kinase (SEV) signaling is to bind Daughter of Sevenless rather than activated SEV. Ptp-2 acts in oocytes downstream of sheath/oocyte gap junctions to promote major sperm protein (MSP)-induced MAP Kinase (MPK-1) phosphorylation. Ptp-2 functions in the oocyte cytoplasm, not at the cell surface to inhibit multiple RasGAPs, resulting in sustained Ras activation. It is thought that MSP triggers PTP-2/Ras activation and ROS production to stimulate MPK-1 activity essential for oocyte maturation and that secreted MSP domains and Cu/Zn superoxide dismutases function antagonistically to control ROS and MAPK signaling. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

Catalytic domain of the Serine/Threonine Kinase, Bone Morphogenetic Protein Type I Receptor; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. BMPR1 functions as a receptor for morphogenetic proteins (BMPs), which are involved in the regulation of cell proliferation, survival, differentiation, and apoptosis. BMPs are able to induce bone, cartilage, ligament, and tendon formation, and may play roles in bone diseases and tumors. Vertebrates contain two type I BMP receptors, BMPR1a and BMPR1b. BMPR1 belongs to a group of receptors for the TGFbeta family of secreted signaling molecules that also includes TGFbeta, activins, growth and differentiation factors, and anti-Mullerian hormone, among others. These receptors contain an extracellular domain that binds ligands, a single transmembrane (TM) region, and a cytoplasmic catalytic kinase domain. Type I receptors, like BMPR1, are low-affinity receptors that bind ligands only after they are recruited by the ligand/type II high-affinity receptor complex. Following activation, they start intracellular signaling to the nucleus by phosphorylating SMAD proteins. Type I receptors contain an additional domain located between the TM and kinase domains called the GS domain, which contains the activating phosphorylation site and confers preference for specific SMAD proteins. The BMPR1 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Mitogen-activated protein kinase kinase kinase kinase 3; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. MAP4K3 plays a role in the nutrient-responsive pathway of mTOR (mammalian target of rapamycin) signaling. MAP4K3 is required in the activation of S6 kinase by amino acids and for the phosphorylation of the mTOR-regulated inhibitor of eukaryotic initiation factor 4E. mTOR regulates ribosome biogenesis and protein translation, and is frequently deregulated in cancer. MAP4Ks are involved in MAPK signaling pathways by activating a MAPK kinase kinase. Each MAPK cascade is activated either by a small GTP-binding protein or by an adaptor protein, which transmits the signal either directly to a MAP3K to start the triple kinase core cascade or indirectly through a mediator kinase, a MAP4K. Members of this subfamily contain an N-terminal catalytic domain and a C-terminal citron homology (CNH) regulatory domain. The MAP4K3 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

173-262 2.37e-15

Src homology 2 (SH2) domain found in Fyn; Fyn is a member of the Src non-receptor type tyrosine kinase family of proteins. Fyn is involved in the control of cell growth and is required in the following pathways: T and B cell receptor signaling, integrin-mediated signaling, growth factor and cytokine receptor signaling, platelet activation, ion channel function, cell adhesion, axon guidance, fertilization, entry into mitosis, and differentiation of natural killer cells, oligodendrocytes and keratinocytes. The protein associates with the p85 subunit of phosphatidylinositol 3-kinase and interacts with the Fyn-binding protein. Alternatively spliced transcript variants encoding distinct isoforms exist. Fyn is primarily localized to the cytoplasmic leaflet of the plasma membrane. Tyrosine phosphorylation of target proteins by Fyn serves to either regulate target protein activity, and/or to generate a binding site on the target protein that recruits other signaling molecules. FYN has been shown to interact with a number of proteins including: BCAR1, Cbl, Janus kinase, nephrin, Sky, tyrosine kinase, Wiskott-Aldrich syndrome protein, and Zap-70. Fyn has a unique N-terminal domain, an SH3 domain, an SH2 domain, a kinase domain and a regulatory tail, as do the other members of the family. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

293-531 2.56e-15

Catalytic domain of the Serine/Threonine Kinase, Thousand-and-One Amino acids 2; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Human TAO2 is also known as prostate-derived Ste20-like kinase (PSK) and was identified in a screen for overexpressed RNAs in prostate cancer. TAO2 possesses mitogen-activated protein kinase (MAPK) kinase kinase activity and activates both p38 and c-Jun N-terminal kinase (JNK), by phosphorylating and activating their respective MAP/ERK kinases, MEK3/MEK6 and MKK4/MKK7. It contains a long C-terminal extension with autoinhibitory segments, and is activated by the release of this inhibition and the phosphorylation of its activation loop serine. TAO2 functions as a regulator of actin cytoskeletal and microtubule organization. In addition, it regulates the transforming growth factor-activated kinase 1 (TAK1), which is a MAPKKK that plays an essential role in the signaling pathways of tumor necrosis factor, interleukin 1, and Toll-like receptor. The TAO2 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

N-terminal Catalytic domain of the Serine/Threonine Kinases, Mitogen-Activated Protein Kinase Kinase Kinase Kinase 4 and 6; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Members of this subfamily contain an N-terminal catalytic domain and a C-terminal citron homology (CNH) regulatory domain. MAP4K4 is also called Nck Interacting kinase (NIK). It facilitates the activation of the MAPKs, extracellular signal-regulated kinase (ERK) 1, ERK2, and c-Jun N-terminal kinase (JNK), by phosphorylating and activating MEKK1. MAP4K4 plays a role in tumor necrosis factor (TNF) alpha-induced insulin resistance. MAP4K4 silencing in skeletal muscle cells from type II diabetic patients restores insulin-mediated glucose uptake. MAP4K4, through JNK, also plays a broad role in cell motility, which impacts inflammation, homeostasis, as well as the invasion and spread of cancer. MAP4K4 is found to be highly expressed in most tumor cell lines relative to normal tissue. MAP4K6 (also called MINK for Misshapen/NIKs-related kinase) is activated after Ras induction and mediates activation of p38 MAPK. MAP4K6 plays a role in cell cycle arrest, cytoskeleton organization, cell adhesion, and cell motility. The MAP4K4/6 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-534 2.67e-15

Catalytic domain of an Uncharacterized subfamily of Mitogen-Activated Protein (MAP)/Extracellular signal-Regulated Kinase (ERK) Kinase Kinase 3-like Serine/Threonine Kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. This subfamily is composed of uncharacterized proteins with similarity to MEKK3, MEKK2, and related proteins; they contain an N-terminal PB1 domain, which mediates oligomerization, and a C-terminal catalytic domain. MEKK2 and MEKK3 are MAPK kinase kinases (MAPKKKs or MKKKs), proteins that phosphorylate and activate MAPK kinases (MAPKKs or MKKs), which in turn phosphorylate and activate MAPKs during signaling cascades that are important in mediating cellular responses to extracellular signals. MEKK2 and MEKK3 activate MEK5 (also called MKK5), which activates ERK5. The ERK5 cascade plays roles in promoting cell proliferation, differentiation, neuronal survival, and neuroprotection. MEKK3 plays an essential role in embryonic angiogenesis and early heart development. MEKK2 and MEKK3 can also activate the MAPKs, c-Jun N-terminal kinase (JNK) and p38, through their respective MAPKKs. The MEKK3-like subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Death-Associated Protein Kinase 3; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. DAPKs mediate cell death and act as tumor suppressors. They are necessary to induce cell death and their overexpression leads to death-associated changes including membrane blebbing, cell rounding, and formation of autophagic vesicles. Vertebrates contain three subfamily members with different domain architecture, localization, and function. DAPK3, also called DAP-like kinase (DLK) and zipper-interacting protein kinase (ZIPk), contains an N-terminal kinase domain and a C-terminal region with nuclear localization signals (NLS) and a leucine zipper motif that mediates homodimerization and interaction with other leucine zipper proteins. It interacts with Par-4, a protein that contains a death domain and interacts with actin filaments. DAPK3 is present in both the cytoplasm and nucleus. Its co-expression with Par-4 results in the co-localization of the two proteins to actin filaments. In addition to cell death, DAPK3 is also implicated in mediating cell motility and the contraction of smooth muscles. The DAPK3 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Polo-like kinase 4; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. PLKs play important roles in cell cycle progression and in DNA damage responses. They regulate mitotic entry, mitotic exit, and cytokinesis. In general PLKs contain an N-terminal catalytic kinase domain and a C-terminal regulatory polo box domain (PBD), which is comprised by two bipartite polo-box motifs (or polo boxes) and is involved in protein interactions. There are five mammalian PLKs (PLK1-5) from distinct genes. PLK4, also called SAK or STK18, is structurally different from other PLKs in that it contains only one polo box that can form two adjacent polo boxes and a functional PDB by homodimerization. It is required for late mitotic progression, cell survival, and embryonic development. It localizes to centrosomes and is required for centriole duplication and chromosomal stability. Overexpression of PLK4 may be associated with colon tumors. The PLK4 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Protein Kinase B gamma (also called Akt3); STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. PKB-gamma is predominantly expressed in neuronal tissues. Mice deficient in PKB-gamma show a reduction in brain weight due to the decreases in cell size and cell number. PKB-gamma has also been shown to be upregulated in estrogen-deficient breast cancer cells, androgen-independent prostate cancer cells, and primary ovarian tumors. It acts as a key mediator in the genesis of ovarian cancer. PKB contains an N-terminal pleckstrin homology (PH) domain and a C-terminal catalytic domain. The PKB-gamma subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

173-262 3.17e-15

Src homology 2 (SH2) domain found in Fyn isoform a like proteins; Fyn is a member of the Src non-receptor type tyrosine kinase family of proteins. This cd contains the SH2 domain found in Fyn isoform a type proteins. Fyn is involved in the control of cell growth and is required in the following pathways: T and B cell receptor signaling, integrin-mediated signaling, growth factor and cytokine receptor signaling, platelet activation, ion channel function, cell adhesion, axon guidance, fertilization, entry into mitosis, and differentiation of natural killer cells, oligodendrocytes and keratinocytes. The protein associates with the p85 subunit of phosphatidylinositol 3-kinase and interacts with the Fyn-binding protein. Alternatively spliced transcript variants encoding distinct isoforms exist. Fyn is primarily localized to the cytoplasmic leaflet of the plasma membrane. Tyrosine phosphorylation of target proteins by Fyn serves to either regulate target protein activity, and/or to generate a binding site on the target protein that recruits other signaling molecules. FYN has been shown to interact with a number of proteins including: BCAR1, Cbl, Janus kinase, nephrin, Sky, tyrosine kinase, Wiskott-Aldrich syndrome protein, and Zap-70. Fyn has a unique N-terminal domain, an SH3 domain, an SH2 domain, a kinase domain and a regulatory tail, as do the other members of the family. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

294-480 3.19e-15

Catalytic domain of Fungal Halotolerance protein 4-like Serine/Threonine kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. This subfamily is composed of HAL4, Saccharomyces cerevisiae Ptk2/Stk2, and similar fungal proteins. Proteins in this subfamily are involved in regulating ion transporters. In budding and fission yeast, HAL4 promotes potassium ion uptake, which increases cellular resistance to other cations such as sodium, lithium, and calcium ions. HAL4 stabilizes the major high-affinity K+ transporter Trk1 at the plasma membrane under low K+ conditions, which prevents endocytosis and vacuolar degradation. Budding yeast Ptk2 phosphorylates and regulates the plasma membrane H+ ATPase, Pma1. The HAL4-like subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

293-478 3.56e-15

Catalytic domain of the Serine/Threonine Kinase, Cyclin-Dependent protein Kinase 4; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. CDK4 partners with all three D-type cyclins (D1, D2, and D3) and is also regulated by INK4 inhibitors. It is active towards the retinoblastoma (pRb) protein and plays a role in regulating the early G1 phase of the cell cycle. It is expressed ubiquitously and is localized in the nucleus. CDK4 also shows kinase activity towards Smad3, a signal transducer of TGF-beta signaling which modulates transcription and plays a role in cell proliferation and apoptosis. CDK4 is inhibited by the p21 inhibitor and is specifically mutated in human melanoma. CDKs belong to a large family of STKs that are regulated by their cognate cyclins. Together, they are involved in the control of cell-cycle progression, transcription, and neuronal function. The CDK4 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-542 3.56e-15

Pseudokinase domain of Kinase Suppressor of Ras 2; The pseudokinase domain shows similarity to protein kinases but lacks crucial residues for catalytic activity. KSR2 interacts with the protein phosphatase calcineurin and functions in calcium-mediated ERK signaling. It also functions in energy metabolism by regulating AMP kinase and AMPK-dependent processes such as glucose uptake and fatty acid oxidation. KSR proteins act as scaffold proteins that function downstream of Ras and upstream of Raf in the Extracellular signal-Regulated Kinase (ERK) pathway that regulates many cellular processes including cycle regulation, proliferation, differentiation, survival, and apoptosis. KSR proteins regulate the assembly and activation of the Raf/MEK/ERK module upon Ras activation at the membrane by direct association of its components. They are widely regarded as pseudokinases. The KSR2 subfamily is part of a larger superfamily that includes the catalytic domains of other protein kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

292-480 4.21e-15

Catalytic domain of the Protein Tyrosine Kinases, Fungal Wee1 proteins; PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. This subfamily is composed of fungal Wee1 proteins, also called Swe1 in budding yeast and Mik1 in fission yeast. Yeast Wee1 is required to control cell size. Wee1 is a cell cycle checkpoint kinase that helps keep the cyclin-dependent kinase CDK1 in an inactive state through phosphorylation of an N-terminal tyr (Y15) residue. During the late G2 phase, CDK1 is activated and mitotic entry is promoted by the removal of this inhibitory phosphorylation by the phosphatase Cdc25. Although Wee1 is functionally a tyr kinase, it is more closely related to serine/threonine kinases (STKs). It contains a catalytic kinase domain sandwiched in between N- and C-terminal regulatory domains. It is regulated by phosphorylation and degradation, and its expression levels are also controlled by circadian clock proteins. The fungal Wee1 subfamily is part of a larger superfamily that includes the catalytic domains of STKs, other PTKs, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Kinase Suppressor of Ras 1; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. KSR1 functions as a transducer of TNFalpha-stimulated C-Raf activation of ERK1/2 and NF-kB. Detected activity of KSR1 is cell type specific and context dependent. It is inactive in normal colon epithelial cells and becomes activated at the onset of inflammatory bowel disease (IBD). Similarly, KSR1 activity is undetectable prior to stimulation by EGF or ceramide in COS-7 or YAMC cells, respectively. KSR proteins are widely regarded as pseudokinases, however, this matter is up for debate as catalytic activity has been detected for KSR1 in some systems. The KSR1 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

169-250 5.70e-15

C-terminal Src homology 2 (C-SH2) domain in Phospholipase C gamma; Phospholipase C gamma is a signaling molecule that is recruited to the C-terminal tail of the receptor upon autophosphorylation of a highly conserved tyrosine. PLCgamma is composed of a Pleckstrin homology (PH) domain followed by an elongation factor (EF) domain, 2 catalytic regions of PLC domains that flank 2 tandem SH2 domains (N-SH2, C-SH2), and ending with a SH3 domain and C2 domain. N-SH2 SH2 domain-mediated interactions represent a crucial step in transmembrane signaling by receptor tyrosine kinases. SH2 domains recognize phosphotyrosine (pY) in the context of particular sequence motifs in receptor phosphorylation sites. Both N-SH2 and C-SH2 have a very similar binding affinity to pY. But in growth factor stimulated cells these domains bind to different target proteins. N-SH2 binds to pY containing sites in the C-terminal tails of tyrosine kinases and other receptors. Recently it has been shown that this interaction is mediated by phosphorylation-independent interactions between a secondary binding site found exclusively on the N-SH2 domain and a region of the FGFR1 tyrosine kinase domain. This secondary site on the SH2 cooperates with the canonical pY site to regulate selectivity in mediating a specific cellular process. C-SH2 binds to an intramolecular site on PLCgamma itself which allows it to hydrolyze phosphatidylinositol-4,5-bisphosphate into diacylglycerol and inositol triphosphate. These then activate protein kinase C and release calcium. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

169-264 5.87e-15

C-terminal Src homology 2 (SH2) domain found in Zeta-chain-associated protein kinase 70 (ZAP-70); ZAP-70 and Syk comprise a family of hematopoietic cell specific protein tyrosine kinases (PTKs) that are required for antigen and antibody receptor function. ZAP-70 is expressed in T and natural killer (NK) cells and Syk is expressed in B cells, mast cells, polymorphonuclear leukocytes, platelets, macrophages, and immature T cells. They are required for the proper development of T and B cells, immune receptors, and activating NK cells. They consist of two N-terminal Src homology 2 (SH2) domains and a C-terminal kinase domain separated from the SH2 domains by a linker or hinge region. Phosphorylation of both tyrosine residues within the Immunoreceptor Tyrosine-based Activation Motifs (ITAM; consensus sequence Yxx[LI]x(7,8)Yxx[LI]) by the Src-family PTKs is required for efficient interaction of ZAP-70 and Syk with the receptor subunits and for receptor function. ZAP-70 forms two phosphotyrosine binding pockets, one of which is shared by both SH2 domains. In Syk the two SH2 domains do not form such a phosphotyrosine-binding site. The SH2 domains here are believed to function independently. In addition, the two SH2 domains of Syk display flexibility in their relative orientation, allowing Syk to accommodate a greater variety of spacing sequences between the ITAM phosphotyrosines and singly phosphorylated non-classical ITAM ligands. This model contains the C-terminus SH2 domains of Zap70. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

Catalytic domain of the Serine/Threonine kinase, Calmodulin Dependent Protein Kinase Kinase 2; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. CaMKKs are upstream kinases of the CaM kinase cascade that phosphorylate and activate CaMKI and CamKIV. They may also phosphorylate other substrates including PKB and AMP-activated protein kinase (AMPK). CaMKK2, also called CaMKK beta, is one of the most versatile CaMKs. It is involved in regulating energy balance, glucose metabolism, adiposity, hematopoiesis, inflammation, and cancer. CaMKK2 contains unique N- and C-terminal domains and a central catalytic kinase domain that is followed by a regulatory domain that bears overlapping autoinhibitory and CaM-binding regions. It can be activated by signaling through G-coupled receptors, IP3 receptors, plasma membrane ion channels, and Toll-like receptors. Thus, CaMKK2 acts as a molecular hub that is capable of receiving and decoding signals from diverse pathways. The CaMKK2 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

169-262 6.76e-15

Src homology 2 (SH2) domain found in B lymphoid kinase (Blk); Blk is a member of the Src non-receptor type tyrosine kinase family of proteins. Blk is expressed in the B-cells. Unlike most other Src members Blk lacks cysteine residues in the SH4 domain that undergo palmitylation. Blk is required for the development of IL-17-producing gamma-delta T cells. Furthermore, Blk is expressed in lymphoid precursors and, in this capacity, plays a role in regulating thymus cellularity during ontogeny. Blk has a unique N-terminal domain, an SH3 domain, an SH2 domain, a kinase domain and a regulatory tail, as do the other members of the family. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

282-533 7.24e-15

Catalytic domain of the dual-specificity Protein Kinase, Mitogen-Activated Protein (MAP)/Extracellular signal-Regulated Kinase (ERK) Kinase 1; PKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine (ST) or tyrosine residues on protein substrates. MEK1 is a dual-specificity PK and a MAPK kinase (MAPKK or MKK) that phosphorylates and activates the downstream targets, ERK1 and ERK2, on specific threonine and tyrosine residues. The ERK cascade starts with extracellular signals including growth factors, hormones, and neurotransmitters, which act through receptors and ion channels to initiate intracellular signaling that leads to the activation at the MAPKKK (Raf-1 or MOS) level, which leads to the transmission of signals to MEK1, and finally to ERK1/2. The ERK cascade plays an important role in cell proliferation, differentiation, oncogenic transformation, and cell cycle control, as well as in apoptosis and cell survival under certain conditions. Gain-of-function mutations in genes encoding ERK cascade proteins, including MEK1, cause cardiofaciocutaneous (CFC) syndrome, a condition leading to multiple congenital anomalies and mental retardation in patients. MEK1 also plays a role in cell cycle control. The MEK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

290-486 8.57e-15

C-terminal catalytic domain of the Serine/Threonine Kinase, Ribosomal S6 kinase 4 (also called Ribosomal protein S6 kinase alpha-6 or 90kDa ribosomal protein S6 kinase 6); STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. RSK4 is also called S6K-alpha-6, RPS6KA6, p90RSK6 or pp90RSK4. RSK4 is a substrate of ERK and is a modulator of p53-dependent proliferation arrest in human cells. Deletion of the RSK4 gene, RPS6KA6, frequently occurs in patients of X-linked deafness type 3, mental retardation and choroideremia. Studies of RSK4 in cancer cells and tissues suggest that it may be oncogenic or tumor suppressive depending on many factors. RSK4 is one of four RSK isoforms (RSK1-4) from distinct genes present in vertebrates. RSKs contain an N-terminal kinase domain (NTD) from the AGC family and a C-terminal kinase domain (CTD) from the CAMK family. They are activated by signaling inputs from extracellular regulated kinase (ERK) and phosphoinositide dependent kinase 1 (PDK1). ERK phosphorylates and activates the CTD of RSK, serving as a docking site for PDK1, which phosphorylates and activates the NTD, which in turn phosphorylates all known RSK substrates. RSKs act as downstream effectors of mitogen-activated protein kinase (MAPK) and play key roles in mitogen-activated cell growth, differentiation, and survival. The RSK4 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Cyclin-Dependent protein Kinase Like 5; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Mutations in the gene encoding CDKL5, previously called STK9, are associated with early onset epilepsy and severe mental retardation [X-linked infantile spasm syndrome (ISSX) or West syndrome]. In addition, CDKL5 mutations also sometimes cause a phenotype similar to Rett syndrome (RTT), a progressive neurodevelopmental disorder. These pathogenic mutations are located in the N-terminal portion of the protein within the kinase domain. CDKs belong to a large family of STKs that are regulated by their cognate cyclins. Together, they are involved in the control of cell-cycle progression, transcription, and neuronal function. The CDKL5 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

173-248 1.10e-14

Src homology 2 (SH2) domain found in Src-related kinase lacking C-terminal regulatory tyrosine and N-terminal myristoylation sites (srm); Srm is a nonreceptor protein kinase that has two SH2 domains, a SH3 domain, and a kinase domain with a tyrosine residue for autophosphorylation. However it lacks an N-terminal glycine for myristoylation and a C-terminal tyrosine which suppresses kinase activity when phosphorylated. Srm is most similar to members of the Tec family who other members include: Tec, Btk/Emb, and Itk/Tsk/Emt. However Srm differs in its N-terminal unique domain it being much smaller than in the Tec family and is closer to Src. Srm is thought to be a new family of nonreceptor tyrosine kinases that may be redundant in function. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

Catalytic domain of the Serine/Threonine kinase, Protein Kinase D; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. PKDs are important regulators of many intracellular signaling pathways such as ERK and JNK, and cellular processes including the organization of the trans-Golgi network, membrane trafficking, cell proliferation, migration, and apoptosis. They contain N-terminal cysteine-rich zinc binding C1 (PKC conserved region 1), central PH (Pleckstrin Homology), and C-terminal catalytic kinase domains. Mammals harbor three types of PKDs: PKD1 (or PKCmu), PKD2, and PKD3 (or PKCnu). PKDs are activated in a PKC-dependent manner by many agents including diacylglycerol (DAG), PDGF, neuropeptides, oxidative stress, and tumor-promoting phorbol esters, among others.

279-479 1.50e-14

N-terminal Catalytic domain of the Serine/Threonine Kinase, Class IIIB myosin; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Class IIIB myosin is expressed highly in retina. It is also present in the brain and testis. The human class IIIB myosin gene maps to a region that overlaps the locus for Bardet-Biedl syndrome, which is characterized by dysmorphic extremities, retinal dystrophy, obesity, male hypogenitalism, and renal abnormalities. Class III myosins are motor proteins containing an N-terminal kinase catalytic domain and a C-terminal actin-binding domain. They may play an important role in maintaining the structural integrity of photoreceptor cell microvilli. They may also function as cargo carriers during light-dependent translocation, in photoreceptor cells, of proteins such as transducin and arrestin. The class III myosin subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine kinase, Calcium/calmodulin-dependent protein kinase Type I delta; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. CaMKs are multifunctional calcium and calmodulin (CaM) stimulated STKs involved in cell cycle regulation. The CaMK family includes CaMKI, CaMKII, CaMKIV, and CaMK kinase (CaMKK). In vertebrates, there are four CaMKI proteins encoded by different genes (alpha, beta, gamma, and delta), each producing at least one variant. CaMKs contain an N-terminal catalytic domain and a C-terminal regulatory domain that harbors a CaM binding site. CaMKI proteins are monomeric and they play pivotal roles in the nervous system, including long-term potentiation, dendritic arborization, neurite outgrowth, and the formation of spines, synapses, and axons. In addition, they may be involved in osteoclast differentiation and bone resorption. The CaMKI-delta subfamily is part of a larger superfamily that includes the catalytic domains of other protein kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

173-259 1.72e-14

Src homology 2 (SH2) domain found in Fyn isoform b like proteins; Fyn is a member of the Src non-receptor type tyrosine kinase family of proteins. This cd contains the SH2 domain found in Fyn isoform b type proteins. Fyn is involved in the control of cell growth and is required in the following pathways: T and B cell receptor signaling, integrin-mediated signaling, growth factor and cytokine receptor signaling, platelet activation, ion channel function, cell adhesion, axon guidance, fertilization, entry into mitosis, and differentiation of natural killer cells, oligodendrocytes and keratinocytes. The protein associates with the p85 subunit of phosphatidylinositol 3-kinase and interacts with the Fyn-binding protein. Alternatively spliced transcript variants encoding distinct isoforms exist. Fyn is primarily localized to the cytoplasmic leaflet of the plasma membrane. Tyrosine phosphorylation of target proteins by Fyn serves to either regulate target protein activity, and/or to generate a binding site on the target protein that recruits other signaling molecules. FYN has been shown to interact with a number of proteins including: BCAR1, Cbl, Janus kinase, nephrin, Sky, tyrosine kinase, Wiskott-Aldrich syndrome protein, and Zap-70. Fyn has a unique N-terminal domain, an SH3 domain, an SH2 domain, a kinase domain and a regulatory tail, as do the other members of the family. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

293-480 2.05e-14

Catalytic domain of Cyclin-Dependent protein Kinase 1-like Serine/Threonine Kinases and of Plant B-type Cyclin-Dependent protein Kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. This subfamily is composed of CDK, CDK2, and CDK3. CDK1 is also called Cell division control protein 2 (Cdc2) or p34 protein kinase, and is regulated by cyclins A, B, and E. The CDK1/cyclin A complex controls G2 phase entry and progression while the CDK1/cyclin B complex is critical for G2 to M phase transition. CDK2 is regulated by cyclin E or cyclin A. Upon activation by cyclin E, it phosphorylates the retinoblastoma (pRb) protein which activates E2F mediated transcription and allows cells to move into S phase. The CDK2/cyclin A complex plays a role in regulating DNA replication. Studies in knockout mice revealed that CDK1 can compensate for the loss of the cdk2 gene as it can also bind cyclin E and drive G1 to S phase transition. CDK3 is regulated by cyclin C and it phosphorylates pRB specifically during the G0/G1 transition. This phosphorylation is required for cells to exit G0 efficiently and enter the G1 phase. The plant-specific B-type CDKs are expressed from the late S to the M phase of the cell cycle. They are characterized by the cyclin binding motif PPT[A/T]LRE. They play a role in controlling mitosis and integrating developmental pathways, such as stomata and leaf development. CdkB has been shown to associate with both cyclin B, which controls G2/M transition, and cyclin D, which acts as a mediator in linking extracellular signals to the cell cycle. CDKs belong to a large family of STKs that are regulated by their cognate cyclins. Together, they are involved in the control of cell-cycle progression, transcription, and neuronal function. The CDK1 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

281-499 2.31e-14

Catalytic domain of the Serine/Threonine Kinase, p38delta Mitogen-Activated Protein Kinase (also called MAPK13); STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. p38delta/MAPK13 is found in skeletal muscle, heart, lung, testis, pancreas, and small intestine. It regulates microtubule function by phosphorylating Tau. It activates the c-jun promoter and plays a role in G2 cell cycle arrest. It also controls the degration of c-Myb, which is associated with myeloid leukemia and poor prognosis in colorectal cancer. p38delta is the main isoform involved in regulating the differentiation and apoptosis of keratinocytes. p38 kinases are MAPKs, serving as important mediators of cellular responses to extracellular signals. They are activated by the MAPK kinases MKK3 and MKK6, which in turn are activated by upstream MAPK kinase kinases including TAK1, ASK1, and MLK3, in response to cellular stresses or inflammatory cytokines. The p38delta subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

287-487 2.32e-14

C-terminal catalytic domain of the Serine/Threonine Kinases, Ribosomal S6 kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. RSKs contain an N-terminal kinase domain (NTD) from the AGC family and a C-terminal kinase domain (CTD) from the CAMK family. They are activated by signaling inputs from extracellular regulated kinase (ERK) and phosphoinositide dependent kinase 1 (PDK1). ERK phosphorylates and activates the CTD of RSK, serving as a docking site for PDK1, which phosphorylates and activates the NTD, which in turn phosphorylates all known RSK substrates. RSKs act as downstream effectors of mitogen-activated protein kinase (MAPK) and play key roles in mitogen-activated cell growth, differentiation, and survival. Mammals possess four RSK isoforms (RSK1-4) from distinct genes. RSK proteins are also referred to as MAP kinase-activated protein kinases (MAPKAPKs), 90 kDa ribosomal protein S6 kinases (p90-RSKs), or p90S6Ks. The RSK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

172-263 2.32e-14

C-terminal Src homology 2 (cSH2) domain found in p85; Phosphoinositide 3-kinases (PI3Ks) are essential for cell growth, migration, and survival. p110, the catalytic subunit, is composed of an adaptor-binding domain, a Ras-binding domain, a C2 domain, a helical domain, and a kinase domain. The regulatory unit is called p85 and is composed of an SH3 domain, a RhoGap domain, a N-terminal SH2 (nSH2) domain, a inter SH2 (iSH2) domain, and C-terminal (cSH2) domain. There are 2 inhibitory interactions between p110alpha and p85 of P13K: 1) p85 nSH2 domain with the C2, helical, and kinase domains of p110alpha and 2) p85 iSH2 domain with C2 domain of p110alpha. There are 3 inhibitory interactions between p110beta and p85 of P13K: 1) p85 nSH2 domain with the C2, helical, and kinase domains of p110beta, 2) p85 iSH2 domain with C2 domain of p110alpha, and 3) p85 cSH2 domain with the kinase domain of p110alpha. It is interesting to note that p110beta is oncogenic as a wild type protein while p110alpha lacks this ability. One explanation is the idea that the regulation of p110beta by p85 is unique because of the addition of inhibitory contacts from the cSH2 domain and the loss of contacts in the iSH2 domain. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

173-262 2.47e-14

Src homology 2 (SH2) domain found in Gardner-Rasheed feline sarcoma viral (v-fgr) oncogene homolog, Fgr; Fgr is a member of the Src non-receptor type tyrosine kinase family of proteins. The protein contains N-terminal sites for myristoylation and palmitoylation, a PTK domain, and SH2 and SH3 domains which are involved in mediating protein-protein interactions with phosphotyrosine-containing and proline-rich motifs, respectively. Fgr is expressed in B-cells and myeloid cells, localizes to plasma membrane ruffles, and functions as a negative regulator of cell migration and adhesion triggered by the beta-2 integrin signal transduction pathway. Multiple alternatively spliced variants, encoding the same protein, have been identified Fgr has been shown to interact with Wiskott-Aldrich syndrome protein. Fgr has a unique N-terminal domain, an SH3 domain, an SH2 domain, a kinase domain and a regulatory tail, as do the other members of the family. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

297-539 2.60e-14

Catalytic domain of the Serine/Threonine kinase, Mitogen-Activated Protein Kinase (MAPK) Kinase Kinase 8; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. MAP3K8 is also called Tumor progression locus 2 (Tpl2) or Cancer Osaka thyroid (Cot), and was first identified as a proto-oncogene in T-cell lymphoma induced by MoMuL virus and in breast carcinoma induced by MMTV. Activated MAP3K8 induces various MAPK pathways including Extracellular Regulated Kinase (ERK) 1/2, c-Jun N-terminal kinase (JNK), and p38. It plays a pivotal role in innate immunity, linking Toll-like receptors to the production of TNF and the activation of ERK in macrophages. It is also required in interleukin-1beta production and is critical in host defense against Gram-positive bacteria. MAP3Ks (MKKKs or MAPKKKs) phosphorylate and activate MAPK kinases (MAPKKs or MKKs or MAP2Ks), which in turn phosphorylate and activate MAPKs during signaling cascades that are important in mediating cellular responses to extracellular signals. The MAP3K8 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-486 2.71e-14

C-terminal kinase domain of the Large Serine/Threonine Kinase and Rho Guanine Nucleotide Exchange Factor, Kalirin; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Kalirin, also called Duo or Duet, is a large multidomain protein containing a series of spectrin-like repeats, two each of RhoGEF and SH3 domains, an immunoglobulin-like (Ig) domain and a C-terminal kinase. As a GEF, it activates Rac1, RhoA, and RhoG. It is highly expressed in neurons and is required for spine formation. The kalirin gene produces at least 10 isoforms from alternative promoter use and splicing. Of the major isoforms (Kalirin-7, -9, and -12), only kalirin-12 contains the C-terminal kinase domain. Kalirin-12 is highly expressed during embryonic development and it plays an important role in axon outgrowth. The Kalirin subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine kinase, Inhibitor of Nuclear Factor-KappaB Kinase (IKK); STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. The IKK complex functions as a master regulator of Nuclear Factor-KappaB (NF-kB) proteins, a family of transcription factors which are critical in many cellular functions including inflammatory responses, immune development, cell survival, and cell proliferation, among others. It is composed of two kinases, IKKalpha and IKKbeta, and the regulatory subunit IKKgamma or NEMO (NF-kB Essential MOdulator). IKKs facilitate the release of NF-kB dimers from an inactive state, allowing them to migrate to the nucleus where they regulate gene transcription. There are two IKK pathways that regulate NF-kB signaling, called the classical (involving IKKbeta and NEMO) and non-canonical (involving IKKalpha) pathways. The classical pathway regulates the majority of genes activated by NF-kB. The IKK subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase (PI3K).

Catalytic domain of the Serine/Threonine Kinase, Mitogen-Activated Protein (MAP)/Extracellular signal-Regulated Kinase (ERK) Kinase Kinase 2; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. MEKK2 is a MAPK kinase kinase (MAPKKK or MKKK), that phosphorylates and activates the MAPK kinase MEK5 (or MKK5), which in turn phosphorylates and activates ERK5. The ERK5 cascade plays roles in promoting cell proliferation, differentiation, neuronal survival, and neuroprotection. MEKK2 also activates ERK1/2, c-Jun N-terminal kinase (JNK) and p38 through their respective MAPKKs MEK1/2, JNK-activating kinase 2 (JNKK2), and MKK3/6. MEKK2 plays roles in T cell receptor signaling, immune synapse formation, cytokine gene expression, as well as in EGF and FGF receptor signaling. The MEKK2 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Cyclin-Dependent protein Kinase 6; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. CDK6 is regulated by D-type cyclins and INK4 inhibitors. It is active towards the retinoblastoma (pRb) protein, implicating it to function in regulating the early G1 phase of the cell cycle. It is expressed ubiquitously and is localized in the cytoplasm. It is also present in the ruffling edge of spreading fibroblasts and may play a role in cell spreading. It binds to the p21 inhibitor without any effect on its own activity and it is overexpressed in squamous cell carcinomas and neuroblastomas. CDK6 has also been shown to inhibit cell differentiation in many cell types. CDKs belong to a large family of STKs that are regulated by their cognate cyclins. Together, they are involved in the control of cell-cycle progression, transcription, and neuronal function. The CDK6 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

290-486 3.34e-14

C-terminal catalytic domain of the Serine/Threonine Kinase, Ribosomal S6 kinase 3 (also called Ribosomal protein S6 kinase alpha-2 or 90kDa ribosomal protein S6 kinase 2); STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. RSK3 is also called S6K-alpha-2, RPS6KA2, p90RSK2 or MAPK-activated protein kinase 1c (MAPKAPK-1c). RSK3 binds muscle A-kinase anchoring protein (mAKAP)-b directly and regulates concentric cardiac myocyte growth. The RSK3 gene, RPS6KA2, is a putative tumor suppressor gene in sporadic epithelial ovarian cancer and variations to the gene may be associated with rectal cancer risk. RSK3 is one of four RSK isoforms (RSK1-4) from distinct genes present in vertebrates. RSKs contain an N-terminal kinase domain (NTD) from the AGC family and a C-terminal kinase domain (CTD) from the CAMK family. They are activated by signaling inputs from extracellular regulated kinase (ERK) and phosphoinositide dependent kinase 1 (PDK1). ERK phosphorylates and activates the CTD of RSK, serving as a docking site for PDK1, which phosphorylates and activates the NTD, which in turn phosphorylates all known RSK substrates. RSKs act as downstream effectors of mitogen-activated protein kinase (MAPK) and play key roles in mitogen-activated cell growth, differentiation, and survival. The RSK3 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine kinase, Interleukin-1 Receptor Associated Kinase 1; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. IRAKs are involved in Toll-like receptor (TLR) and interleukin-1 (IL-1) signalling pathways, and are thus critical in regulating innate immune responses and inflammation. IRAKs contain an N-terminal Death domain (DD), a proST region (rich in serines, prolines, and threonines), a central kinase domain, and a C-terminal domain; IRAK-4 lacks the C-terminal domain. Vertebrates contain four IRAKs (IRAK-1, -2, -3 (or -M), and -4) that display distinct functions and patterns of expression and subcellular distribution, and can differentially mediate TLR signaling. IRAK1 plays a role in the activation of IRF3/7, STAT, and NFkB. It mediates IL-6 and IFN-gamma responses following IL-1 and IL-18 stimulation, respectively. It also plays an essential role in IFN-alpha induction downstream of TLR7 and TLR9. The IRAK1 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

293-500 3.61e-14

Catalytic domain of the Serine/Threonine Kinase, PFTAIRE-1 kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. PFTAIRE-1 is widely expressed except in the spleen and thymus. It is highly expressed in the brain, heart, pancreas, testis, and ovary, and is localized in the cytoplasm. It is regulated by cyclin D3 and is inhibited by the p21 cell cycle inhibitor. It has also been shown to interact with the membrane-associated cyclin Y, which recruits the protein to the plasma membrane. PFTAIRE-1 shares sequence similarity with Cyclin-Dependent Kinases (CDKs), which belong to a large family of STKs that are regulated by their cognate cyclins. Together, CDKs and cyclins are involved in the control of cell-cycle progression, transcription, and neuronal function. The PFTAIRE-1 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

168-248 3.82e-14

Src homology 2 (SH2) domain in the Breast Cancer Anti-estrogen Resistance protein 3; BCAR3 is part of a growing family of guanine nucleotide exchange factors is responsible for activation of Ras-family GTPases, including Sos1 and 2, GRF1 and 2, CalDAG-GEF/GRP1-4, C3G, cAMP-GEF/Epac 1 and 2, PDZ-GEFs, MR-GEF, RalGDS family members, RalGPS, RasGEF, Smg GDS, and phospholipase C(epsilon). 12102558 21262352 BCAR3 binds to the carboxy-terminus of BCAR1/p130Cas, a focal adhesion adapter protein. Over expression of BCAR1 (p130Cas) and BCAR3 induces estrogen independent growth in normally estrogen-dependent cell lines. They have been linked to resistance to anti-estrogens in breast cancer, Rac activation, and cell motility, though the BCAR3/p130Cas complex is not required for this activity in BCAR3. Many BCAR3-mediated signaling events in epithelial and mesenchymal cells are independent of p130Cas association. Structurally these proteins contain a single SH2 domain upstream of their RasGEF domain, which is responsible for the ability of BCAR3 to enhance p130Cas over-expression-induced migration. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

288-548 3.89e-14

Catalytic domain of the Serine/Threonine Kinase, Bone Morphogenetic Protein Type IB; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. BMPR1b, also called Activin receptor-Like Kinase 6 (ALK6), functions as a receptor for bone morphogenetic proteins (BMPs), which are involved in the regulation of cell proliferation, survival, differentiation, and apoptosis. BMPs are able to induce bone, cartilage, ligament, and tendon formation, and may play roles in bone diseases and tumors. Mutations in BMPR1b that led to inhibition of chondrogenesis can cause Brachydactyly (BD) type A2, a dominant hand malformation characterized by shortening and lateral deviation of the index fingers. A point mutation in the BMPR1b kinase domain is also associated with the Booroola phenotype, characterized by precocious differentiation of ovarian follicles. BMPR1b belongs to a group of receptors for the TGFbeta family of secreted signaling molecules that includes TGFbeta, BMPs, activins, growth and differentiation factors, and anti-Mullerian hormone, among others. These receptors contain an extracellular domain that binds ligands, a single transmembrane (TM) region, and a cytoplasmic catalytic kinase domain. Type I receptors, like BMPR1b, are low-affinity receptors that bind ligands only after they are recruited by the ligand/type II high-affinity receptor complex. Following activation, they start intracellular signaling to the nucleus by phosphorylating SMAD proteins. Type I receptors contain an additional domain located between the TM and kinase domains called the GS domain, which contains the activating phosphorylation site and confers preference for specific SMAD proteins. The BMPR1b subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Atypical Protein Kinase C iota; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. PKC-iota is directly implicated in carcinogenesis. It is critical to oncogenic signaling mediated by Ras and Bcr-Abl. The PKC-iota gene is the target of tumor-specific gene amplification in many human cancers, and has been identified as a human oncogene. In addition to its role in transformed growth, PKC-iota also promotes invasion, chemoresistance, and tumor cell survival. Expression profiling of PKC-iota is a prognostic marker of poor clinical outcome in several human cancers. PKC-iota also plays a role in establishing cell polarity, and has critical embryonic functions. PKCs are classified into three groups (classical, atypical, and novel) depending on their mode of activation and the structural characteristics of their regulatory domain. aPKCs only require phosphatidylserine (PS) for activation. The aPKC subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Protein Kinase B alpha (also called Akt1); STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. PKB-alpha is predominantly expressed in endothelial cells. It is critical for the regulation of angiogenesis and the maintenance of vascular integrity. It also plays a role in adipocyte differentiation. Mice deficient in PKB-alpha exhibit perinatal morbidity, growth retardation, reduction in body weight accompanied by reduced sizes of multiple organs, and enhanced apoptosis in some cell types. PKB-alpha activity has been reported to be frequently elevated in breast and prostate cancers. In some cancer cells, PKB-alpha may act as a suppressor of metastasis. PKB contains an N-terminal pleckstrin homology (PH) domain and a C-terminal catalytic domain. The PKB-alpha subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

276-486 5.09e-14

C-terminal catalytic domain of the Serine/Threonine Kinase, Mitogen and stress-activated kinase 1; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. MSK1 plays a role in the regulation of translational control and transcriptional activation. It phosphorylates the transcription factors, CREB and NFkB. It also phosphorylates the nucleosomal proteins H3 and HMG-14. Increased phosphorylation of MSK1 is associated with the development of cerebral ischemic/hypoxic preconditioning. MSKs contain an N-terminal kinase domain (NTD) from the AGC family and a C-terminal kinase domain (CTD) from the CAMK family. MSKs are activated by two major signaling cascades, the Ras-MAPK and p38 stress kinase pathways, which trigger phosphorylation in the activation loop (A-loop) of the CTD of MSK. The active CTD phosphorylates the hydrophobic motif (HM) of NTD, which facilitates the phosphorylation of the A-loop and activates the NTD, which in turn phosphorylates downstream targets. The MSK1 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-478 5.13e-14

Catalytic domain of the Serine/Threonine Kinase, Protein Kinase B; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. There are three PKB isoforms from different genes, PKB-alpha (or Akt1), PKB-beta (or Akt2), and PKB-gamma (or Akt3). PKB contains an N-terminal pleckstrin homology (PH) domain and a C-terminal catalytic domain. It is activated downstream of phosphoinositide 3-kinase (PI3K) and plays important roles in diverse cellular functions including cell survival, growth, proliferation, angiogenesis, motility, and migration. PKB also has a central role in a variety of human cancers, having been implicated in tumor initiation, progression, and metastasis. The PKB subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and PI3K.

173-248 5.42e-14

Src homology 2 (SH2) domain found in Nck; Nck proteins are adaptors that modulate actin cytoskeleton dynamics by linking proline-rich effector molecules to tyrosine kinases or phosphorylated signaling intermediates. There are two members known in this family: Nck1 (Nckalpha) and Nck2 (Nckbeta and Growth factor receptor-bound protein 4 (Grb4)). They are characterized by having 3 SH3 domains and a C-terminal SH2 domain. Nck1 and Nck2 have overlapping functions as determined by gene knockouts. Both bind receptor tyrosine kinases and other tyrosine-phosphorylated proteins through their SH2 domains. In addition they also bind distinct targets. Neuronal signaling proteins: EphrinB1, EphrinB2, and Disabled-1 (Dab-1) all bind to Nck-2 exclusively. And in the case of PDGFR, Tyr(P)751 binds to Nck1 while Tyr(P)1009 binds to Nck2. Nck1 and Nck2 have a role in the infection process of enteropathogenic Escherichia coli (EPEC). Their SH3 domains are involved in recruiting and activating the N-WASP/Arp2/3 complex inducing actin polymerization resulting in the production of pedestals, dynamic bacteria-presenting protrusions of the plasma membrane. A similar thing occurs in the vaccinia virus where motile plasma membrane projections are formed beneath the virus. Recently it has been shown that the SH2 domains of both Nck1 and Nck2 bind the G-protein coupled receptor kinase-interacting protein 1 (GIT1) in a phosphorylation-dependent manner. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

166-262 6.49e-14

Src homology 2 (SH2) domain found in Tec protein, Bruton's tyrosine kinase (Btk); A member of the Tec protein tyrosine kinase Btk is expressed in bone marrow, spleen, all hematopoietic cells except T lymphocytes and plasma cells where it plays a crucial role in B cell maturation and mast cell activation. Btk has been shown to interact with GNAQ, PLCG2, protein kinase D1, B-cell linker, SH3BP5, caveolin 1, ARID3A, and GTF2I. Most of the Tec family members have a PH domain (Txk and the short (type 1) splice variant of Drosophila Btk29A are exceptions), a Tec homology (TH) domain, a SH3 domain, a SH2 domain, and a protein kinase catalytic domain. Btk is implicated in the primary immunodeficiency disease X-linked agammaglobulinemia (Bruton's agammaglobulinemia). The TH domain consists of a Zn2+-binding Btk motif and a proline-rich region. The Btk motif is found in Tec kinases, Ras GAP, and IGBP. It is crucial for the function of Tec PH domains and it's lack of presence in Txk is not surprising since it lacks a PH domain. The type 1 splice form of the Drosophila homolog also lacks both the PH domain and the Btk motif. The proline-rich regions are highly conserved for the most part with the exception of Bmx whose residues surrounding the PXXP motif are not conserved (TH-like) and Btk29A which is entirely unique with large numbers of glycine residues (TH-extended). Tec family members all lack a C-terminal tyrosine having an autoinhibitory function in its phosphorylated state. Two tyrosine phosphorylation (pY) sites have been identified in Btk: one located in the activation loop of the catalytic domain which regulates the transition between open (active) and closed (inactive) states and the other in its SH3 domain. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

Catalytic domain of the Serine/Threonine kinase, eukaryotic translation Initiation Factor 2-Alpha Kinase 2 or Protein Kinase regulated by RNA; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. PKR (or EIF2AK2) contains an N-terminal double-stranded RNA (dsRNA) binding domain and a C-terminal catalytic kinase domain. It is activated by dsRNA, which is produced as a replication intermediate in virally infected cells. It plays a key role in mediating innate immune responses to viral infection. PKR is also directly activated by PACT (protein activator of PKR) and heparin, and is inhibited by viral proteins and RNAs. PKR also regulates transcription and signal transduction in diseased cells, playing roles in tumorigenesis and neurodegenerative diseases. EIF2AKs phosphorylate the alpha subunit of eIF-2, resulting in the downregulation of protein synthesis. The PKR subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Src homology 2 (SH2) domain found in Tec protein, Txk; A member of the Tec protein tyrosine kinase Txk is expressed in thymus, spleen, lymph node, T lymphocytes, NK cells, mast cell lines, and myeloid cell line. Txk plays a role in TCR signal transduction, T cell development, and selection which is analogous to the function of Itk. Txk has been shown to interact with IFN-gamma. Unlike most of the Tec family members Txk lacks a PH domain. Instead Txk has a unique region containing a palmitoylated cysteine string which has a similar membrane tethering function as the PH domain. Txk also has a zinc-binding motif, a SH3 domain, a SH2 domain, and a protein kinase catalytic domain. The TH domain consists of a Zn2+-binding Btk motif and a proline-rich region. The Btk motif is found in Tec kinases, Ras GAP, and IGBP and crucial to the function of the PH domain. It is not present in Txk which is not surprising since it lacks a PH domain.

N-terminal Catalytic domain of the Serine/Threonine Kinase, Class IIIA myosin; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Class IIIA myosin is highly expressed in retina and in inner ear hair cells. It is localized to the distal ends of actin-bundled structures. Mutations in human myosin IIIA are responsible for progressive nonsyndromic hearing loss. Human myosin IIIA possesses ATPase and kinase activities, and the ability to move actin filaments in a motility assay. It may function as a cellular transporter capable of moving along actin bundles in sensory cells. Class III myosins are motor proteins containing an N-terminal kinase catalytic domain and a C-terminal actin-binding domain. Class III myosins may play an important role in maintaining the structural integrity of photoreceptor cell microvilli. In photoreceptor cells, they may also function as cargo carriers during light-dependent translocation of proteins such as transducin and arrestin. The class III myosin subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Src homology 2 (SH2) domain found in Nck; Nck proteins are adaptors that modulate actin cytoskeleton dynamics by linking proline-rich effector molecules to tyrosine kinases or phosphorylated signaling intermediates. There are two members known in this family: Nck1 (Nckalpha) and Nck2 (Nckbeta and Growth factor receptor-bound protein 4 (Grb4)). They are characterized by having 3 SH3 domains and a C-terminal SH2 domain. Nck1 and Nck2 have overlapping functions as determined by gene knockouts. Both bind receptor tyrosine kinases and other tyrosine-phosphorylated proteins through their SH2 domains. In addition they also bind distinct targets. Neuronal signaling proteins: EphrinB1, EphrinB2, and Disabled-1 (Dab-1) all bind to Nck-2 exclusively. And in the case of PDGFR, Tyr(P)751 binds to Nck1 while Tyr(P)1009 binds to Nck2. Nck1 and Nck2 have a role in the infection process of enteropathogenic Escherichia coli (EPEC). Their SH3 domains are involved in recruiting and activating the N-WASP/Arp2/3 complex inducing actin polymerization resulting in the production of pedestals, dynamic bacteria-presenting protrusions of the plasma membrane. A similar thing occurs in the vaccinia virus where motile plasma membrane projections are formed beneath the virus. Recently it has been shown that the SH2 domains of both Nck1 and Nck2 bind the G-protein coupled receptor kinase-interacting protein 1 (GIT1) in a phosphorylation-dependent manner. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

294-529 8.45e-14

Catalytic domain of the Serine/Threonine Kinase, 70 kDa ribosomal protein S6 kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. p70S6K (or S6K) contains only one catalytic kinase domain, unlike p90 ribosomal S6 kinases (RSKs). It acts as a downstream effector of the STK mTOR (mammalian Target of Rapamycin) and plays a role in the regulation of the translation machinery during protein synthesis. p70S6K also plays a pivotal role in regulating cell size and glucose homeostasis. Its targets include S6, the translation initiation factor eIF3, and the insulin receptor substrate IRS-1, among others. Mammals contain two isoforms of p70S6K, named S6K1 and S6K2 (or S6K-beta). The p70S6K subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

297-529 8.98e-14

Catalytic domain of fungal Rim15-like Protein Serine/Threonine Kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Members of this group include Saccharomyces cerevisiae Rim15, Schizosaccharomyces pombe cek1, and similar fungal proteins. They contain a central catalytic domain, which contains an insert relative to MAST kinases. In addition, Rim15 contains a C-terminal signal receiver (REC) domain while cek1 contains an N-terminal PAS domain. Rim15 (or Rim15p) functions as a regulator of meiosis. It acts as a downstream effector of PKA and regulates entry into stationary phase (G0). Thus, it plays a crucial role in regulating yeast proliferation, differentiation, and aging. Cek1 may facilitate progression of mitotic anaphase. The Rim15-like subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, p38 Mitogen-Activated Protein Kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. p38 kinases are mitogen-activated protein kinases (MAPKs), serving as important mediators of cellular responses to extracellular signals. They function in the regulation of the cell cycle, cell development, cell differentiation, senescence, tumorigenesis, apoptosis, pain development and pain progression, and immune responses. p38 kinases are activated by the MAPK kinases MKK3 and MKK6, which in turn are activated by upstream MAPK kinase kinases including TAK1, ASK1, and MLK3, in response to cellular stresses or inflammatory cytokines. p38 substrates include other protein kinases and factors that regulate transcription, nuclear export, mRNA stability and translation. p38 kinases are drug targets for the inflammatory diseases psoriasis, rheumatoid arthritis, and chronic pulmonary disease. Vertebrates contain four isoforms of p38, named alpha, beta, gamma, and delta, which show varying substrate specificity and expression patterns. p38alpha and p38beta are ubiquitously expressed, p38gamma is predominantly found in skeletal muscle, and p38delta is found in the heart, lung, testis, pancreas, and small intestine. The p38 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

327-534 1.26e-13

Catalytic domain of the Serine/Threonine Kinase, Polo-like kinase 2; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. PLKs play important roles in cell cycle progression and in DNA damage responses. They regulate mitotic entry, mitotic exit, and cytokinesis. In general PLKs contain an N-terminal catalytic kinase domain and a C-terminal regulatory polo box domain (PBD), which is comprised by two bipartite polo-box motifs (or polo boxes) and is involved in protein interactions. There are five mammalian PLKs (PLK1-5) from distinct genes. PLK2, also called Snk (serum-inducible kinase), functions in G1 progression, S-phase arrest, and centriole duplication. Its gene is responsive to both growth factors and cellular stress, is a transcriptional target of p53, and activates a G2-M checkpoint. The PLK2 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-499 1.29e-13

Catalytic domain of the Serine/Threonine Kinase, p38beta Mitogen-Activated Protein Kinase (also called MAPK11); STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. p38beta/MAPK11 is widely expressed in tissues and shows more similarity with p38alpha than with the other isoforms. Both are sensitive to pyridinylimidazoles and share some common substrates such as MAPK activated protein kinase 2 (MK2) and the transcription factors ATF2, c-Fos and, ELK-1. p38beta is involved in regulating the activation of the cyclooxygenase-2 promoter and the expression of TGFbeta-induced alpha-smooth muscle cell actin. p38 kinases are mitogen-activated protein kinases (MAPKs), serving as important mediators of cellular responses to extracellular signals. They are activated by the MAPK kinases MKK3 and MKK6, which in turn are activated by upstream MAPK kinase kinases including TAK1, ASK1, and MLK3, in response to cellular stresses or inflammatory cytokines. The p38beta subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Death-associated protein kinase-Related Apoptosis-inducing protein Kinase 1; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. DRAKs were named based on their similarity (around 50% identity) to the kinase domain of DAPKs. They contain an N-terminal kinase domain and a C-terminal regulatory domain. Vertebrates contain two subfamily members, DRAK1 (also called STK17A) and DRAK2. Both DRAKs are localized to the nucleus, autophosphorylate themselves, and phosphorylate myosin light chain as a substrate. Rabbit DRAK1 has been shown to induce apoptosis in osteoclasts and overexpressio of human DRAK1 induces apoptosis in cultured fibroblast cells. DRAK1 may be involved in apoptotic signaling. The DRAK1 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

C-terminal Src homology 2 (SH2) domain found in SH2 domains, ANK, and kinase domain (shark) proteins; These non-receptor protein-tyrosine kinases contain two SH2 domains, five ankyrin (ANK)-like repeats, and a potential tyrosine phosphorylation site in its carboxyl-terminal tail which resembles the phosphorylation site in members of the src family. Like, mammalian non-receptor protein-tyrosine kinases, ZAP-70 and syk proteins, they do not have SH3 domains. However, the presence of ANK makes these unique among protein-tyrosine kinases. Both tyrosine kinases and ANK repeats have been shown to transduce developmental signals, and SH2 domains are known to participate intimately in tyrosine kinase signaling. These tyrosine kinases are believed to be involved in epithelial cell polarity. The members of this family include the shark (SH2 domains, ANK, and kinase domain) gene in Drosophila and yellow fever mosquitos, as well as the hydra protein HTK16. Drosophila Shark is proposed to transduce intracellularly the Crumbs, a protein necessary for proper organization of ectodermal epithelia, intercellular signal. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

Catalytic domain of the Serine/Threonine protein kinase, With No Lysine (WNK) 4; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. WNK4 shows a restricted expression pattern and is usually found in epithelial cells. It is expressed in nephrons and in extrarenal tissues including intestine, eye, mammary glands, and prostate. WNK4 regulates a variety of ion transport proteins including apical or basolateral ion transporters, ion channels in the transcellular pathway, and claudins in the paracellular pathway. Mutations in WNK4 cause PseudoHypoAldosteronism type II (PHAII), characterized by hypertension and hyperkalemia. WNK4 inhibits the activity of the thiazide-sensitive Na-Cl cotransporter (NCC), which is responsible for about 15% of NaCl reabsorption in the kidney. It also inhibits the renal outer medullary potassium channel (ROMK) and decreases its surface expression. Hypertension and hyperkalemia in PHAII patients with WNK4 mutations may be partly due to increased NaCl reabsorption through NCC and impaired renal potassium secretion by ROMK, respectively. The WNK4 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, p21-activated kinase 6; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. PAK6 may play a role in stress responses through its activation by the mitogen-activated protein kinase (MAPK) p38 and MAPK kinase 6 (MKK6) pathway. PAK6 is highly expressed in the brain. It is not required for viability, but together with PAK5, it is required for normal levels of locomotion and activity, and for learning and memory. Increased expression of PAK6 is found in primary and metastatic prostate cancer. PAK6 may play a role in the regulation of motility. PAK6 belongs to the group II PAKs, which contain a PBD (p21-binding domain) and a C-terminal catalytic domain, but do not harbor an AID (autoinhibitory domain) or SH3 binding sites. PAKs are Rho family GTPase-regulated kinases that serve as important mediators in the function of Cdc42 (cell division cycle 42) and Rac. The PAK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Transforming Growth Factor beta Type II Receptor; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. TGFbR2 belongs to a group of receptors for the TGFbeta family of secreted signaling molecules that includes TGFbeta, bone morphogenetic proteins, activins, growth and differentiation factors, and anti-Mullerian hormone, among others. These receptors contain an extracellular domain that binds ligands, a single transmembrane region, and a cytoplasmic catalytic kinase domain. Type II receptors, such as TGFbR2, are high-affinity receptors which bind ligands, autophosphorylate, as well as trans-phosphorylate and activate low-affinity type I receptors. TGFbR2 acts as the receptor for TGFbeta, which is crucial in growth control and homeostasis in many different tissues. It plays roles in regulating apoptosis and in maintaining the balance between self renewal and cell loss. It also plays a key role in maintaining vascular integrity and in regulating responses to genotoxic stress. Mutations in TGFbR2 can cause aortic aneurysm disorders such as Loeys-Dietz and Marfan syndromes. The TGFbR2 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Protein Serine/Threonine Kinase, Serum- and Glucocorticoid-induced Kinase 1; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. SGK1 is ubiquitously expressed and is under transcriptional control of numerous stimuli including cell stress (cell shrinkage), serum, hormones (gluco- and mineralocorticoids), gonadotropins, growth factors, interleukin-6, and other cytokines. It plays roles in sodium retention and potassium elimination in the kidney, nutrient transport, salt sensitivity, memory consolidation, and cardiac repolarization. A common SGK1 variant is associated with increased blood pressure and body weight. SGK1 may also contribute to tumor growth, neurodegeneration, fibrosing disease, and ischemia. The SGK1 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Death-associated protein kinase-Related Apoptosis-inducing protein Kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. DRAKs, also called STK17, were named based on their similarity (around 50% identity) to the kinase domain of DAPKs. They contain an N-terminal kinase domain and a C-terminal regulatory domain. Vertebrates contain two subfamily members, DRAK1 and DRAK2. Both DRAKs are localized to the nucleus, autophosphorylate themselves, and phosphorylate myosin light chain as a substrate. They may play a role in apoptotic signaling. The DRAK subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

301-534 2.54e-13

Catalytic domain of the Serine/Threonine Kinase, Polo-like kinase 1; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. PLKs play important roles in cell cycle progression and in DNA damage responses. They regulate mitotic entry, mitotic exit, and cytokinesis. In general PLKs contain an N-terminal catalytic kinase domain and a C-terminal regulatory polo box domain (PBD), which is comprised by two bipartite polo-box motifs (or polo boxes) and is involved in protein interactions. There are five mammalian PLKs (PLK1-5) from distinct genes. PLK1 functions as a positive regulator of mitosis, meiosis, and cytokinesis. Its localization changes during mitotic progression; associating first with centrosomes in prophase, with kinetochores in prometaphase and metaphase, at the central spindle in anaphase, and in the midbody during telophase. It carries multiple functions throughout the cell cycle through interactions with differrent substrates at these specific subcellular locations. PLK1 is overexpressed in many human cancers and is associated with poor prognosis. The PLK1 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

293-534 3.03e-13

Catalytic domain of the Dual-specificity protein kinase, Myt1; Dual-specificity PKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine as well as tyrosine residues on protein substrates. Myt1 is a cytoplasmic cell cycle checkpoint kinase that can keep the cyclin-dependent kinase CDK1 in an inactive state through phosphorylation of N-terminal thr (T14) and tyr (Y15) residues, leading to the delay of meiosis I entry. Meiotic progression is ensured by a two-step inhibition and downregulation of Myt1 by CDK1/XRINGO and p90Rsk during oocyte maturation. In addition, Myt1 targets cyclin B1/B2 and is essential for Golgi and ER assembly during telophase. In Drosophila, Myt1 may be a downstream target of Notch during eye development. The Myt1 subfamily is part of a larger superfamily that includes the catalytic domains of other protein serine/threonine PKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-539 3.36e-13

Catalytic domain of the Serine/Threonine Kinase, Polo-like kinase 3; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. PLKs play important roles in cell cycle progression and in DNA damage responses. They regulate mitotic entry, mitotic exit, and cytokinesis. In general PLKs contain an N-terminal catalytic kinase domain and a C-terminal regulatory polo box domain (PBD), which is comprised by two bipartite polo-box motifs (or polo boxes) and is involved in protein interactions. There are five mammalian PLKs (PLK1-5) from distinct genes. PLK3, also called Prk or Fnk (FGF-inducible kinase), regulates angiogenesis and responses to DNA damage. Activated PLK3 mediates Chk2 phosphorylation by ATM and the resulting checkpoint activation. PLK3 phosphorylates DNA polymerase delta and may be involved in DNA repair. It also inhibits Cdc25c, thereby regulating the onset of mitosis. The PLK3 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine protein kinase, Casein Kinase 1; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. CK1 phosphorylates a variety of substrates including enzymes, transcription and splice factors, cytoskeletal proteins, viral oncogenes, receptors, and membrane-associated proteins. There are mutliple isoforms of CK1 and in mammals, seven isoforms (alpha, beta, gamma1-3, delta, and epsilon) have been characterized. These isoforms differ mainly in the length and structure of their C-terminal non-catalytic region. Some isoforms have several splice variants such as the long (L) and short (S) variants of CK1alpha. CK1 proteins are involved in the regulation of many cellular processes including membrane transport processes, circadian rhythm, cell division, apoptosis, and the development of cancer and neurodegenerative diseases. The CK1 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Death-Associated Protein Kinase 2; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. DAPKs mediate cell death and act as tumor suppressors. They are necessary to induce cell death and their overexpression leads to death-associated changes including membrane blebbing, cell rounding, and formation of autophagic vesicles. Vertebrates contain three subfamily members with different domain architecture, localization, and function. DAPK2, also called DAPK-related protein 1 (DRP-1), is a Ca2+/calmodulin (CaM)-regulated protein containing an N-terminal kinase domain, a CaM autoinhibitory site and a dimerization module. It lacks the cytoskeletal binding regions of DAPK1 and the exogenous protein has been shown to be soluble and cytoplasmic. FLAG-tagged DAPK2, however, accumulated within membrane-enclosed autophagic vesicles. It is unclear where endogenous DAPK2 is localized. DAPK2 participates in TNF-alpha and FAS-receptor induced cell death and enhances neutrophilic maturation in myeloid leukemic cells. It contributes to the induction of anoikis and its down-regulation is implicated in the beta-catenin induced resistance of malignant epithelial cells to anoikis. The DAPK2 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Atypical Protein Kinase C zeta; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. PKC-zeta plays a critical role in activating the glucose transport response. It is activated by glucose, insulin, and exercise through diverse pathways. PKC-zeta also plays a central role in maintaining cell polarity in yeast and mammalian cells. In addition, it affects actin remodeling in muscle cells. PKCs are classified into three groups (classical, atypical, and novel) depending on their mode of activation and the structural characteristics of their regulatory domain. aPKCs only require phosphatidylserine (PS) for activation. The aPKC-zeta subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

293-486 4.48e-13

N-terminal catalytic domain of the Serine/Threonine Kinase, Mitogen and stress-activated kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. MSKs contain an N-terminal kinase domain (NTD) from the AGC family and a C-terminal kinase domain (CTD) from the CAMK family. MSKs are activated by two major signaling cascades, the Ras-MAPK and p38 stress kinase pathways, in response to various stimuli such as growth factors, hormones, neurotransmitters, cellular stress, and pro-inflammatory cytokines. This triggers phosphorylation in the activation loop (A-loop) of the CTD of MSK. The active CTD phosphorylates the hydrophobic motif (HM) in the C-terminal extension of NTD, which facilitates the phosphorylation of the A-loop and activates the NTD, which in turn phosphorylates downstream targets. MSKs are predominantly nuclear proteins. They are widely expressed in many tissues including heart, brain, lung, liver, kidney, and pancreas. There are two isoforms of MSK, called MSK1 and MSK2. The MSK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

172-248 4.66e-13

N-terminal Src homology 2 (SH2) domain found in SH2 domains, ANK, and kinase domain (shark) proteins; These non-receptor protein-tyrosine kinases contain two SH2 domains, five ankyrin (ANK)-like repeats, and a potential tyrosine phosphorylation site in the carboxyl-terminal tail which resembles the phosphorylation site in members of the src family. Like, mammalian non-receptor protein-tyrosine kinases, ZAP-70 and syk proteins, they do not have SH3 domains. However, the presence of ANK makes these unique among protein-tyrosine kinases. Both tyrosine kinases and ANK repeats have been shown to transduce developmental signals, and SH2 domains are known to participate intimately in tyrosine kinase signaling. These tyrosine kinases are believed to be involved in epithelial cell polarity. The members of this family include the shark (SH2 domains, ANK, and kinase domain) gene in Drosophila and yellow fever mosquitos, as well as the hydra protein HTK16. Drosophila Shark is proposed to transduce intracellularly the Crumbs, a protein necessary for proper organization of ectodermal epithelia, intercellular signal. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

Catalytic domain of the Serine/Threonine kinase, PDLIM1 interacting kinase 1 like; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. PDIK1L is also called STK35 or CLIK-1. It is predominantly a nuclear protein which is capable of autophosphorylation. Through its interaction with the PDZ-LIM protein CLP-36, it is localized to actin stress fibers. The PDIK1L subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase (PI3K).

Catalytic domain of the Serine/Threonine Kinase, p21-activated kinase 5; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. PAK5 is mainly expressed in the brain. It is not required for viability, but together with PAK6, it is required for normal levels of locomotion and activity, and for learning and memory. PAK5 cooperates with Inca (induced in neural crest by AP2) in the regulation of cell adhesion and cytoskeletal organization in the embryo and in neural crest cells during craniofacial development. PAK5 may also play a role in controlling the signaling of Raf-1, an effector of Ras, at the mitochondria. PAK5 belongs to the group II PAKs, which contain a PBD (p21-binding domain) and a C-terminal catalytic domain, but do not harbor an AID (autoinhibitory domain) or SH3 binding sites. PAKs are Rho family GTPase-regulated kinases that serve as important mediators in the function of Cdc42 (cell division cycle 42) and Rac. The PAK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine kinase, Inhibitor of Nuclear Factor-KappaB Kinase (IKK) alpha; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. IKKalpha is involved in the non-canonical or alternative pathway of regulating Nuclear Factor-KappaB (NF-kB) proteins, a family of transcription factors which are critical in many cellular functions including inflammatory responses, immune development, cell survival, and cell proliferation, among others. The non-canonical pathway functions in cells lacking NEMO (NF-kB Essential MOdulator) and IKKbeta. It is induced by a subset of TNFR family members including CD40, RANK, and B cell-activating factor receptor. IKKalpha processes the Inhibitor of NF-kB (IkB)-like C-terminus of NF-kB2/p100 to produce p52, allowing the p52/RelB dimer to migrate to the nucleus. This pathway is dependent on NIK (NF-kB Inducing Kinase) which phosphorylates and activates IKKalpha. The IKKalpha subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

173-248 6.49e-13

N-terminal Src homology 2 (N-SH2) domain in Phospholipase C gamma; Phospholipase C gamma is a signaling molecule that is recruited to the C-terminal tail of the receptor upon autophosphorylation of a highly conserved tyrosine. PLCgamma is composed of a Pleckstrin homology (PH) domain followed by an elongation factor (EF) domain, 2 catalytic regions of PLC domains that flank 2 tandem SH2 domains (N-SH2, C-SH2), and ending with a SH3 domain and C2 domain. N-SH2 SH2 domain-mediated interactions represent a crucial step in transmembrane signaling by receptor tyrosine kinases. SH2 domains recognize phosphotyrosine (pY) in the context of particular sequence motifs in receptor phosphorylation sites. Both N-SH2 and C-SH2 have a very similar binding affinity to pY. But in growth factor stimulated cells these domains bind to different target proteins. N-SH2 binds to pY containing sites in the C-terminal tails of tyrosine kinases and other receptors. Recently it has been shown that this interaction is mediated by phosphorylation-independent interactions between a secondary binding site found exclusively on the N-SH2 domain and a region of the FGFR1 tyrosine kinase domain. This secondary site on the SH2 cooperates with the canonical pY site to regulate selectivity in mediating a specific cellular process. C-SH2 binds to an intramolecular site on PLCgamma itself which allows it to hydrolyze phosphatidylinositol-4,5-bisphosphate into diacylglycerol and inositol triphosphate. These then activate protein kinase C and release calcium. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

Catalytic domain of the Serine/Threonine protein kinase, With No Lysine (WNK) 3; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. WNK3 shows a restricted expression pattern; it is found at high levels in the pituary glands and is also expressed in the kidney and brain. It has been shown to regulate many ion transporters including members of the SLC12A family of cation-chloride cotransporters such as NCC and NKCC2, the renal potassium channel ROMK, and the epithelial calcium channels TRPV5 and TRPV6. WNK3 appears to sense low-chloride hypotonic stress and under these conditions, it activates SPAK, which directly interacts and phosphorylates cation-chloride cotransporters. WNK3 has also been shown to promote cell survival, possibly through interaction with procaspase-3 and HSP70. WNKs comprise a subfamily of STKs with an unusual placement of the catalytic lysine relative to all other protein kinases. The WNK3 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

168-262 1.21e-12

Src homology 2 (SH2) domain found in the Vav1 proteins; Proto-oncogene vav is a member of the Dbl family of guanine nucleotide exchange factors (GEF) for the Rho family of GTP binding proteins. All vavs are activated by tyrosine phosphorylation leading to their activation. There are three Vav mammalian family members: Vav1 which is expressed in the hematopoietic system, and Vav2 and Vav3 are more ubiquitously expressed. Vav1 plays a role in T-cell and B-cell development and activation. It has been identified as the specific binding partner of Nef proteins from HIV-1, resulting in morphological changes, cytoskeletal rearrangements, and the JNK/SAPK signaling cascade, leading to increased levels of viral transcription and replication. Vav1 has been shown to interact with Ku70, PLCG1, Lymphocyte cytosolic protein 2, Janus kinase 2, SIAH2, S100B, Abl gene, ARHGDIB, SHB, PIK3R1, PRKCQ, Grb2, MAPK1, Syk, Linker of activated T cells, Cbl gene and EZH2. Vav proteins are involved in several processes that require cytoskeletal reorganization, such as the formation of the immunological synapse (IS), phagocytosis, platelet aggregation, spreading, and transformation. Vavs function as guanine nucleotide exchange factors (GEFs) for the Rho/Rac family of GTPases. Vav family members have several conserved motifs/domains including: a leucine-rich region, a leucine-zipper, a calponin homology (CH) domain, an acidic domain, a Dbl-homology (DH) domain, a pleckstrin homology (PH) domain, a cysteine-rich domain, 2 SH3 domains, a proline-rich region, and a SH2 domain. Vavs are the only known Rho GEFs that have both the DH/PH motifs and SH2/SH3 domains in the same protein. The leucine-rich helix-loop-helix (HLH) domain is thought to be involved in protein heterodimerization with other HLH proteins and it may function as a negative regulator by forming inactive heterodimers. The CH domain is usually involved in the association with filamentous actin, but in Vav it controls NFAT stimulation, Ca2+ mobilization, and its transforming activity. Acidic domains are involved in protein-protein interactions and contain regulatory tyrosines. The DH domain is a GDP-GTP exchange factor on Rho/Rac GTPases. The PH domain in involved in interactions with GTP-binding proteins, lipids and/or phosphorylated serine/threonine residues. The SH3 domain is involved in localization of proteins to specific sites within the cell interacting with protein with proline-rich sequences. The SH2 domain mediates a high affinity interaction with tyrosine phosphorylated proteins. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

294-480 1.28e-12

Pseudokinase domain of Interleukin-1 Receptor Associated Kinase 3; The pseudokinase domain shows similarity to protein kinases but lacks crucial residues for catalytic activity. IRAKs are involved in Toll-like receptor (TLR) and interleukin-1 (IL-1) signalling pathways, and are thus critical in regulating innate immune responses and inflammation. IRAKs contain an N-terminal Death domain (DD), a proST region (rich in serines, prolines, and threonines), a central kinase domain (a pseudokinase in the case of IRAK3), and a C-terminal domain; IRAK-4 lacks the C-terminal domain. Vertebrates contain four IRAKs (IRAK-1, -2, -3 (or -M), and -4) that display distinct functions and patterns of expression and subcellular distribution, and can differentially mediate TLR signaling. IRAK3 (or IRAK-M) is the only IRAK that does not show kinase activity. It is found only in monocytes and macrophages in humans, and functions as a negative regulator of TLR signaling including TLR-2 induced p38 activation. It also negatively regulates the alternative NFkB pathway in a TLR-2 specific manner. IRAK3 is downregulated in the monocytes of obese people, and is associated with high SOD2, a marker of mitochondrial oxidative stress. It is an important inhibitor of inflammation in association with obesity and metabolic syndrome. The IRAK3 subfamily is part of a larger superfamily that includes the catalytic domains of other protein serine/threonine kinases, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

169-262 1.55e-12

Src homology 2 (SH2) domain found in Lyn; Lyn is a member of the Src non-receptor type tyrosine kinase family of proteins and is expressed in the hematopoietic cells, in neural tissues, liver, and adipose tissue. There are two alternatively spliced forms of Lyn. Lyn plays an inhibitory role in myeloid lineage proliferation. Following engagement of the B cell receptors, Lyn undergoes rapid phosphorylation and activation, triggering a cascade of signaling events mediated by Lyn phosphorylation of tyrosine residues within the immunoreceptor tyrosine-based activation motifs (ITAM) of the receptor proteins, and subsequent recruitment and activation of other kinases including Syk, phospholipase C2 (PLC2) and phosphatidyl inositol-3 kinase. These kinases play critical roles in proliferation, Ca2+ mobilization and cell differentiation. Lyn plays an essential role in the transmission of inhibitory signals through phosphorylation of tyrosine residues within the immunoreceptor tyrosine-based inhibitory motifs (ITIM) in regulatory proteins such as CD22, PIR-B and FC RIIb1. Their ITIM phosphorylation subsequently leads to recruitment and activation of phosphatases such as SHIP-1 and SHP-1 which further down modulate signaling pathways, attenuate cell activation and can mediate tolerance. Lyn also plays a role in the insulin signaling pathway. Activated Lyn phosphorylates insulin receptor substrate 1 (IRS1) leading to an increase in translocation of Glut-4 to the cell membrane and increased glucose utilization. It is the primary Src family member involved in signaling downstream of the B cell receptor. Lyn plays an unusual, 2-fold role in B cell receptor signaling; it is essential for initiation of signaling but is also later involved in negative regulation of the signal. Lyn has a unique N-terminal domain, an SH3 domain, an SH2 domain, a kinase domain and a regulatory tail, as do the other members of the family. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

294-534 1.72e-12

Catalytic domain of the Serine/Threonine Kinases, Plant TDY Mitogen-Activated Protein Kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Plant MAPKs are typed based on the conserved phosphorylation motif present in the activation loop, TEY and TDY. This subfamily represents the TDY subtype and is composed of Group D plant MAPKs including Arabidopsis thaliana MPK18 (AtMPK18), Oryza sativa Blast- and Wound-induced MAPK1 (OsBWMK1), OsWJUMK1 (Wound- and JA-Uninducible MAPK1), Zea mays MPK6, and the Medicago sativa TDY1 gene product. OsBWMK1 enhances resistance to pathogenic infections. It mediates stress-activated defense responses by activating a transcription factor that affects the expression of stress-related genes. AtMPK18 is involved in microtubule-related functions. In plants, MAPKs are associated with physiological, developmental, hormonal, and stress responses. Some plants show numerous gene duplications of MAPKs; Arabidopsis thaliana harbors at least 20 MAPKs, named AtMPK1-20 while Oryza sativa contains at least 17 MAPKs. Arabidopsis thaliana contains more TEY-type MAPKs than TDY-type, whereas the reverse is true for Oryza sativa. The TDY MAPK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-499 1.73e-12

Catalytic domain of the Serine/Threonine Kinase, Novel Protein Kinase C epsilon; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. PKC-epsilon has been shown to behave as an oncoprotein. Its overexpression contributes to neoplastic transformation depending on the cell type. It contributes to oncogenesis by inducing disordered cell growth and inhibiting cell death. It also plays a role in tumor invasion and metastasis. PKC-epsilon has also been found to confer cardioprotection against ischemia and reperfusion-mediated damage. Other cellular functions include the regulation of gene expression, cell adhesion, and cell motility. PKCs are classified into three groups (classical, atypical, and novel) depending on their mode of activation and the structural characteristics of their regulatory domain. nPKCs are calcium-independent, but require DAG (1,2-diacylglycerol) and phosphatidylserine (PS) for activity. The nPKC-epsilon subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

The SH2 domains of Grb7, Grb10 and Grb14 preferentially bind to a different RTK. Grb7 binds strongly to the erbB2 receptor, unlike Grb10 and Grb14 which bind weakly to it. Grb14 binds to Fibroblast Growth Factor Receptor (FGFR). Grb10 has been shown to interact with many different proteins, including the insulin and IGF1 receptors, platelet-derived growth factor (PDGF) receptor-beta, Ret, Kit, Raf1 and MEK1, and Nedd4. Grb7 family proteins are phosphorylated on serine/threonine as well as tyrosine residues. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

169-259 2.09e-12

Src homology 2 (SH2) domain found in Yes; Yes is a member of the Src non-receptor type tyrosine kinase family of proteins. Yes is the cellular homolog of the Yamaguchi sarcoma virus oncogene. In humans it is encoded by the YES1 gene which maps to chromosome 18 and is in close proximity to thymidylate synthase. A corresponding Yes pseudogene has been found on chromosome 22. YES1 has been shown to interact with Janus kinase 2, CTNND1,RPL10, and Occludin. Yes1 has a unique N-terminal domain, an SH3 domain, an SH2 domain, a kinase domain and a regulatory tail, as do the other members of the family. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

303-513 2.44e-12

Pseudokinase domain of STE20-related kinase adapter protein; The pseudokinase domain shows similarity to protein kinases but lacks crucial residues for catalytic activity. STRAD forms a complex with the scaffolding protein MO25, and the serine/threonine kinase (STK), LKB1, resulting in the activation of the kinase. In the complex, LKB1 phosphorylates and activates adenosine monophosphate-activated protein kinases (AMPKs), which regulate cell energy metabolism and cell polarity. LKB1 is a tumor suppressor linked to the rare inherited disease, Peutz-Jeghers syndrome, which is characterized by a predisposition to benign polyps and hyperpigmentation of the buccal mucosa. There are two forms of STRAD, alpha and beta, that complex with LKB1 and MO25. The structure of STRAD-alpha is available and shows that this protein binds ATP, has an ordered activation loop, and adopts a closed conformation typical of fully active protein kinases. It does not possess activity due to nonconservative substitutions of essential catalytic residues. ATP binding enhances the affinity of STRAD for MO25. The conformation of STRAD-alpha stabilized through ATP and MO25 may be needed to activate LKB1. The STRAD subfamily is part of a larger superfamily that includes the catalytic domains of STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, p21-activated kinase 4; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. PAK4 regulates cell morphology and cytoskeletal organization. It is essential for embryonic viability and proper neural development. Mice lacking PAK4 die due to defects in the fetal heart. In addition, their spinal cord motor neurons showed failure to differentiate and migrate. PAK4 also plays a role in cell survival and tumorigenesis. It is overexpressed in many primary tumors including colon, esophageal, and mammary tumors. PAK4 has also been implicated in viral and bacterial infection pathways. PAK4 belongs to the group II PAKs, which contain a PBD (p21-binding domain) and a C-terminal catalytic domain, but do not harbor an AID (autoinhibitory domain) or SH3 binding sites. PAKs are Rho family GTPase-regulated kinases that serve as important mediators in the function of Cdc42 (cell division cycle 42) and Rac. The PAK subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

324-508 2.58e-12

Catalytic domain of the Serine/Threonine Kinase, Calcium/calmodulin-dependent serine protein kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. CASK belongs to the MAGUK (membrane-associated guanylate kinase) protein family, which functions as multiple domain adaptor proteins and is characterized by the presence of a core of three domains: PDZ, SH3, and guanylate kinase (GuK). The enzymatically inactive GuK domain in MAGUK proteins mediates protein-protein interactions and associates intramolecularly with the SH3 domain. In addition, CASK contains a catalytic kinase and two L27 domains. It is highly expressed in the nervous system and plays roles in synaptic protein targeting, neural development, and regulation of gene expression. Binding partners include parkin (a Parkinson's disease molecule), neurexin (adhesion molecule), syndecans, calcium channel proteins, CINAP (nucleosome assembly protein), transcription factor Tbr-1, and the cytoplasmic adaptor proteins Mint1, Veli/mLIN-7/MALS, SAP97, caskin, and CIP98. Deletion or mutations in the CASK gene have been implicated in X-linked mental retardation. The CASK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Cyclin-Dependent protein Kinase 9; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. CDK9, together with a cyclin partner (cyclin T1, T2a, T2b, or K), is the main component of distinct positive transcription elongation factors (P-TEFb), which function as Ser2 C-terminal domain kinases of RNA polymerase II. P-TEFb participates in multiple steps of gene expression including transcription elongation, mRNA synthesis, processing, export, and translation. It also plays a role in mediating cytokine induced transcription networks such as IL6-induced STAT3 signaling. In addition, the CDK9/cyclin T2a complex promotes muscle differentiation and enhances the function of some myogenic regulatory factors. CDKs belong to a large family of STKs that are regulated by their cognate cyclins. Together, they are involved in the control of cell-cycle progression, transcription, and neuronal function. The CDK9 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

C-terminal catalytic domain of the Serine/Threonine Kinase, Mitogen and stress-activated kinase 2; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. MSK2 and MSK1 play nonredundant roles in activating histone H3 kinases, which play pivotal roles in compaction of the chromatin fiber. MSK2 is the required H3 kinase in response to stress stimuli and activation of the p38 MAPK pathway. MSK2 also plays a role in the pathogenesis of psoriasis. MSKs contain an N-terminal kinase domain (NTD) from the AGC family and a C-terminal kinase domain (CTD) from the CAMK family, similar to 90 kDa ribosomal protein S6 kinases (RSKs). MSKs are activated by two major signaling cascades, the Ras-MAPK and p38 stress kinase pathways, which trigger phosphorylation in the activation loop (A-loop) of the CTD of MSK. The active CTD phosphorylates the hydrophobic motif (HM) of NTD, which facilitates the phosphorylation of the A-loop and activates the NTD, which in turn phosphorylates downstream targets. The MSK2 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Src homology 2 (SH2) domain found in Tec protein, Bmx; A member of the Tec protein tyrosine kinase Bmx is expressed in the endothelium of large arteries, fetal endocardium, adult endocardium of the left ventricle, bone marrow, lung, testis, granulocytes, myeloid cell lines, and prostate cell lines. Bmx is involved in the regulation of Rho and serum response factor (SRF). Bmx has been shown to interact with PAK1, PTK2, PTPN21, and RUFY1. Most of the Tec family members have a PH domain (Txk and the short (type 1) splice variant of Drosophila Btk29A are exceptions), a Tec homology (TH) domain, a SH3 domain, a SH2 domain, and a protein kinase catalytic domain. The TH domain consists of a Zn2+-binding Btk motif and a proline-rich region. The Btk motif is found in Tec kinases, Ras GAP, and IGBP. It is crucial for the function of Tec PH domains. It is not present in Txk and the type 1 splice form of the Drosophila homolog. The proline-rich regions are highly conserved for the most part with the exception of Bmx whose residues surrounding the PXXP motif are not conserved (TH-like) and Btk29A which is entirely unique with large numbers of glycine residues (TH-extended). Tec family members all lack a C-terminal tyrosine having an autoinhibitory function in its phosphorylated state. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

Catalytic domain of the Serine/Threonine kinase, Tousled-Like Kinase 2; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. TLKs play important functions during the cell cycle and are implicated in chromatin remodeling, DNA replication and repair, and mitosis. They phosphorylate and regulate Anti-silencing function 1 protein (Asf1), a histone H3/H4 chaperone that helps facilitate the assembly of chromatin following DNA replication during S phase. TLKs also phosphorylate the H3 histone tail and are essential in transcription. Vertebrates contain two subfamily members, TLK1 and TLK2. The TLK2 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase (PI3K).

294-513 3.87e-12

Catalytic domain of the Serine/Threonine Kinases, Fungal Mitogen-Activated Protein Kinases Sty1 and Hog1; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. This subfamily is composed of the MAPKs Sty1 from Schizosaccharomyces pombe, Hog1 from Saccharomyces cerevisiae, and similar proteins. Sty1 and Hog1 are stress-activated MAPKs that partipate in transcriptional regulation in response to stress. Sty1 is activated in response to oxidative stress, osmotic stress, and UV radiation. It is regulated by the MAP2K Wis1, which is activated by the MAP3Ks Wis4 and Win1, which receive signals of the stress condition from membrane-spanning histidine kinases Mak1-3. Activated Sty1 stabilizes the Atf1 transcription factor and induces transcription of Atf1-dependent genes of the core environmetal stress response. Hog1 is the key element in the high osmolarity glycerol (HOG) pathway and is activated upon hyperosmotic stress. Activated Hog1 accumulates in the nucleus and regulates stress-induced transcription. The HOG pathway is mediated by two transmembrane osmosensors, Sln1 and Sho1. MAPKs are important mediators of cellular responses to extracellular signals. The Sty1/Hog1 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

297-432 4.13e-12

Catalytic domain of the Serine/Threonine Kinase, Cell Division Cycle 2-like 1; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. CDC2L1, also called PITSLRE, exists in different isoforms which are named using the alias CDK11(p). The CDC2L1 gene produces two protein products, CDK11(p110) and CDK11(p58). CDC2L1 is also represented by the caspase-processed CDK11(p46). CDK11(p110), the major isoform, associates with cyclin L and is expressed throughout the cell cycle. It is involved in RNA processing and the regulation of transcription. CDK11(p58) associates with cyclin D3 and is expressed during the G2/M phase of the cell cycle. It plays roles in spindle morphogenesis, centrosome maturation, sister chromatid cohesion, and the completion of mitosis. CDK11(p46) is formed from the larger isoforms by caspases during TNFalpha- and Fas-induced apoptosis. It functions as a downstream effector kinase in apoptotic signaling pathways and interacts with eukaryotic initiation factor 3f (eIF3f), p21-activated kinase (PAK1), and Ran-binding protein (RanBPM). CDKs belong to a large family of STKs that are regulated by their cognate cyclins. Together, they are involved in the control of cell-cycle progression, transcription, and neuronal function. The CDC2L1 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

289-486 4.53e-12

Catalytic domain of the Serine/Threonine kinase, Calcium/calmodulin-dependent protein kinase Type IV; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. CaMKs are multifunctional calcium and calmodulin (CaM) stimulated STKs involved in cell cycle regulation. There are several types of CaMKs including CaMKI, CaMKII, and CaMKIV. CaMKs contain an N-terminal catalytic domain and a C-terminal regulatory domain that harbors a CaM binding site. CaMKIV is found predominantly in neurons and immune cells. It is activated by the binding of calcium/CaM and phosphorylation by CaMKK (alpha or beta). The CaMKK-CaMKIV cascade participates in regulating several transcription factors like CREB, MEF2, and retinoid orphan receptors. It also is implicated in T-cell development and signaling, cytokine secretion, and signaling through Toll-like receptors, and is thus, pivotal in immune response and inflammation. The CaMKIV subfamily is part of a larger superfamily that includes the catalytic domains of other protein kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

282-494 4.77e-12

Catalytic domain of the dual-specificity Protein Kinase, Mitogen-Activated Protein (MAP)/Extracellular signal-Regulated Kinase (ERK) Kinase 2; PKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine (ST) or tyrosine residues on protein substrates. MEK2 is a dual-specificity PK and a MAPK kinase (MAPKK or MKK) that phosphorylates and activates the downstream targets, ERK1 and ERK2, on specific threonine and tyrosine residues. The ERK cascade starts with extracellular signals including growth factors, hormones, and neurotransmitters, which act through receptors and ion channels to initiate intracellular signaling that leads to the activation at the MAPKKK (Raf-1 or MOS) level, which leads to the transmission of signals to MEK2, and finally to ERK1/2. The ERK cascade plays an important role in cell proliferation, differentiation, oncogenic transformation, and cell cycle control, as well as in apoptosis and cell survival under certain conditions. Gain-of-function mutations in genes encoding ERK cascade proteins, including MEK2, cause cardiofaciocutaneous (CFC) syndrome, a condition leading to multiple congenital anomalies and mental retardation in patients. The MEK subfamily is part of a larger superfamily that includes the catalytic domains of other protein serine/threonine kinases, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-513 4.82e-12

Catalytic domain of the Serine/Threonine Kinase, p38gamma Mitogen-Activated Protein Kinase (also called MAPK12); STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. p38gamma/MAPK12 is predominantly expressed in skeletal muscle. Unlike p38alpha and p38beta, p38gamma is insensitive to pyridinylimidazoles. It displays an antagonizing function compared to p38alpha. p38gamma inhibits, while p38alpha stimulates, c-Jun phosphorylation and AP-1 mediated transcription. p38gamma also plays a role in the signaling between Ras and the estrogen receptor and has been implicated to increase cell invasion and breast cancer progression. In Xenopus, p38gamma is critical in the meiotic maturation of oocytes. p38 kinases are MAPKs, serving as important mediators of cellular responses to extracellular signals. They are activated by the MAPK kinases MKK3 and MKK6, which in turn are activated by upstream MAPK kinase kinases including TAK1, ASK1, and MLK3, in response to cellular stresses or inflammatory cytokines. The p38gamma subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

The MEK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

289-534 5.58e-12

Catalytic domain of the Serine/Threonine kinase, Proviral Integration Moloney virus (PIM) kinase 2; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. The PIM gene locus was discovered as a result of the cloning of retroviral intergration sites in murine Moloney leukemia virus, leading to the identification of PIM kinases. They are constitutively active STKs with a broad range of cellular targets and are overexpressed in many haematopoietic malignancies and solid cancers. Vertebrates contain three distinct PIM kinase genes (PIM1-3); each gene may result in mutliple protein isoforms. There are three PIM2 isoforms resulting from alternative translation initiation sites. PIM2 is highly expressed in leukemia and lymphomas and has been shown to promote the survival and proliferation of tumor cells. The PIM2 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

168-247 6.13e-12

Src homology 2 (SH2) domain found in SH2B adapter proteins (SH2B1, SH2B2, SH2B3); SH2B3 (Lnk), like other members of the SH2B adapter protein family, contains a pleckstrin homology domain, at least one dimerization domain, and a C-terminal SH2 domain which binds to phosphorylated tyrosines in a variety of tyrosine kinases. SH2B3 negatively regulates lymphopoiesis and early hematopoiesis. The lnk-deficiency results in enhanced production of B cells, and expansion as well as enhanced function of hematopoietic stem cells (HSCs), demonstrating negative regulatory functions of Sh2b3/Lnk in cytokine signaling. Sh2b3/Lnk also functions in responses controlled by cell adhesion and in crosstalk between integrin- and cytokine-mediated signaling. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

173-248 6.33e-12

C-terminal Src homology 2 (SH2) domain found in Ras GTPase-activating protein 1 (GAP); RasGAP is part of the GAP1 family of GTPase-activating proteins. The protein is located in the cytoplasm and stimulates the GTPase activity of normal RAS p21, but not its oncogenic counterpart. Acting as a suppressor of RAS function, the protein enhances the weak intrinsic GTPase activity of RAS proteins resulting in RAS inactivation, thereby allowing control of cellular proliferation and differentiation. Mutations leading to changes in the binding sites of either protein are associated with basal cell carcinomas. Alternative splicing results in two isoforms. The shorter isoform which lacks the N-terminal hydrophobic region, has the same activity, and is expressed in placental tissues. In general longer isoform contains 2 SH2 domains, a SH3 domain, a pleckstrin homology (PH) domain, and a calcium-dependent phospholipid-binding C2 domain. The C-terminus contains the catalytic domain of RasGap which catalyzes the activation of Ras by hydrolyzing GTP-bound active Ras into an inactive GDP-bound form of Ras. This model contains the C-terminal SH2 domain. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

Catalytic domain of Yeast Protein Kinase 1-like Serine/Threonine Kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. This subfamily is composed of fungal proteins with similarity to the AGC STKs, Saccharomyces cerevisiae YPK1 and Schizosaccharomyces pombe Gad8p. YPK1 is required for cell growth and acts as a downstream kinase in the sphingolipid-mediated signaling pathway of yeast. It also plays a role in efficient endocytosis and in the maintenance of cell wall integrity. Gad8p is a downstream target of Tor1p, the fission yeast homolog of mTOR. It plays a role in cell growth and sexual development. The YPK1-like subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Mitogen-Activated Protein (MAP)/Extracellular signal-Regulated Kinase (ERK) Kinase Kinase 3; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. MEKK3 is a MAPK kinase kinase (MAPKKK or MKKK), that phosphorylates and activates the MAPK kinase MEK5 (or MKK5), which in turn phosphorylates and activates ERK5. The ERK5 cascade plays roles in promoting cell proliferation, differentiation, neuronal survival, and neuroprotection. MEKK3 plays an essential role in embryonic angiogenesis and early heart development. In addition, MEKK3 is involved in interleukin-1 receptor and Toll-like receptor 4 signaling. It is also a specific regulator of the proinflammatory cytokines IL-6 and GM-CSF in some immune cells. MEKK3 also regulates calcineurin, which plays a critical role in T cell activation, apoptosis, skeletal myocyte differentiation, and cardiac hypertrophy. The MEKK3 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-488 7.86e-12

Catalytic domain of Phototropin-like Serine/Threonine Kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Phototropins are blue-light receptors that control responses such as phototropism, stromatal opening, and chloroplast movement in order to optimize the photosynthetic efficiency of plants. They are light-activated STKs that contain an N-terminal photosensory domain and a C-terminal catalytic domain. The N-terminal domain contains two LOV (Light, Oxygen or Voltage) domains that binds FMN. Photoexcitation of the LOV domains results in autophosphorylation at multiple sites and activation of the catalytic domain. In addition to plant phototropins, included in this subfamily are predominantly uncharacterized fungal STKs whose catalytic domains resemble the phototropin kinase domain. One protein from Neurospora crassa is called nrc-2, which plays a role in growth and development by controlling entry into the conidiation program. The phototropin-like subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

168-247 9.92e-12

Src homology 2 (SH2) domain found in suppressor of cytokine signaling (SOCS) proteins; SH2 domain found in SOCS proteins. SOCS was first recognized as a group of cytokine-inducible SH2 (CIS) domain proteins comprising eight family members in human (CIS and SOCS1-SOCS7). In addition to the SH2 domain, SOCS proteins have a variable N-terminal domain and a conserved SOCS box in the C-terminal domain. SOCS proteins bind to a substrate via their SH2 domain. The prototypical members, CIS and SOCS1-SOCS3, have been shown to regulate growth hormone signaling in vitro and in a classic negative feedback response compete for binding at phosphotyrosine sites in JAK kinase and receptor pathways to displace effector proteins and target bound receptors for proteasomal degradation. Loss of SOCS activity results in excessive cytokine signaling associated with a variety of hematopoietic, autoimmune, and inflammatory diseases and certain cancers. Members (SOCS4-SOCS7) were identified by their conserved SOCS box, an adapter motif of 3 helices that associates substrate binding domains, such as the SOCS SH2 domain, ankryin, and WD40 with ubiquitin ligase components. These show limited cytokine induction. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

172-247 1.51e-11

Src homology 2 (SH2) domain found in suppressor of cytokine signaling (SOCS) family; SH2 domain found in SOCS proteins. SOCS was first recognized as a group of cytokine-inducible SH2 (CIS) domain proteins comprising eight family members in human (CIS and SOCS1-SOCS7). In addition to the SH2 domain, SOCS proteins have a variable N-terminal domain and a conserved SOCS box in the C-terminal domain. SOCS proteins bind to a substrate via their SH2 domain. The prototypical members, CIS and SOCS1-SOCS3, have been shown to regulate growth hormone signaling in vitro and in a classic negative feedback response compete for binding at phosphotyrosine sites in JAK kinase and receptor pathways to displace effector proteins and target bound receptors for proteasomal degradation.

173-262 1.51e-11

Src homology 2 (SH2) domain found in the Vav3 proteins; Proto-oncogene vav is a member of the Dbl family of guanine nucleotide exchange factors (GEF) for the Rho family of GTP binding proteins. All vavs are activated by tyrosine phosphorylation leading to their activation. There are three Vav mammalian family members: Vav1 which is expressed in the hematopoietic system, and Vav2 and Vav3 are more ubiquitously expressed. Vav3 preferentially activates RhoA, RhoG and, to a lesser extent, Rac1. Alternatively spliced transcript variants encoding different isoforms have been described for this gene. VAV3 has been shown to interact with Grb2. Vav proteins are involved in several processes that require cytoskeletal reorganization, such as the formation of the immunological synapse (IS), phagocytosis, platelet aggregation, spreading, and transformation. Vavs function as guanine nucleotide exchange factors (GEFs) for the Rho/Rac family of GTPases. Vav family members have several conserved motifs/domains including: a leucine-rich region, a leucine-zipper, a calponin homology (CH) domain, an acidic domain, a Dbl-homology (DH) domain, a pleckstrin homology (PH) domain, a cysteine-rich domain, 2 SH3 domains, a proline-rich region, and a SH2 domain. Vavs are the only known Rho GEFs that have both the DH/PH motifs and SH2/SH3 domains in the same protein. The leucine-rich helix-loop-helix (HLH) domain is thought to be involved in protein heterodimerization with other HLH proteins and it may function as a negative regulator by forming inactive heterodimers. The CH domain is usually involved in the association with filamentous actin, but in Vav it controls NFAT stimulation, Ca2+ mobilization, and its transforming activity. Acidic domains are involved in protein-protein interactions and contain regulatory tyrosines. The DH domain is a GDP-GTP exchange factor on Rho/Rac GTPases. The PH domain in involved in interactions with GTP-binding proteins, lipids and/or phosphorylated serine/threonine residues. The SH3 domain is involved in localization of proteins to specific sites within the cell interacting with protein with proline-rich sequences. The SH2 domain mediates a high affinity interaction with tyrosine phosphorylated proteins. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

341-476 1.55e-11

C-terminal catalytic domain of the Serine/Threonine Kinase, Mitogen and stress-activated kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. MSKs contain an N-terminal kinase domain (NTD) from the AGC family and a C-terminal kinase domain (CTD) from the CAMK family. MSKs are activated by two major signaling cascades, the Ras-MAPK and p38 stress kinase pathways, in response to various stimuli such as growth factors, hormones, neurotransmitters, cellular stress, and pro-inflammatory cytokines. This triggers phosphorylation in the activation loop (A-loop) of the CTD of MSK. The active CTD phosphorylates the hydrophobic motif (HM) in the C-terminal extension of NTD, which facilitates the phosphorylation of the A-loop and activates the NTD, which in turn phosphorylates downstream targets. MSKs are predominantly nuclear proteins. They are widely expressed in many tissues including heart, brain, lung, liver, kidney, and pancreas. There are two isoforms of MSK, called MSK1 and MSK2. The MSK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

287-478 1.58e-11

Catalytic domain of Extracellular signal-Regulated Kinase 1 and 2-like Serine/Threonine Kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. This subfamily is composed of the mitogen-activated protein kinases (MAPKs) ERK1, ERK2, baker's yeast Fus3, and similar proteins. MAPK pathways are important mediators of cellular responses to extracellular signals. ERK1/2 activation is preferentially by mitogenic factors, differentiation stimuli, and cytokines, through a kinase cascade involving the MAPK kinases MEK1/2 and a MAPK kinase kinase from the Raf family. ERK1/2 have numerous substrates, many of which are nuclear and participate in transcriptional regulation of many cellular processes. They regulate cell growth, cell proliferation, and cell cycle progression from G1 to S phase. Although the distinct roles of ERK1 and ERK2 have not been fully determined, it is known that ERK2 can maintain most functions in the absence of ERK1, and that the deletion of ERK2 is embryonically lethal. The MAPK, Fus3, regulates yeast mating processes including mating-specific gene expression, G1 arrest, mating projection, and cell fusion. This ERK1/2-like subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-499 1.88e-11

Catalytic domain of the Serine/Threonine Kinases, Mitogen-Activated Protein Kinases 4 (also called ERK4) and 6 (also called ERK3); STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. MAPK4 (also called ERK4 or p63MAPK) and MAPK6 (also called ERK3 or p97MAPK) are atypical MAPKs that are not regulated by MAPK kinases. MAPK6 is expressed ubiquitously with highest amounts in brain and skeletal muscle. It may be involved in the control of cell differentiation by negatively regulating cell cycle progression in certain conditions. It may also play a role in glucose-induced insulin secretion. MAPK6 and MAPK4 cooperate to regulate the activity of MAPK-activated protein kinase 5 (MK5), leading to its relocation to the cytoplasm and exclusion from the nucleus. The MAPK6/MK5 and MAPK4/MK5 pathways may play critical roles in embryonic and post-natal development. MAPKs are important mediators of cellular responses to extracellular signals. The MAPK4/6 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

308-474 1.95e-11

Catalytic kinase domain, second repeat, of the Giant Serine/Threonine Kinase Obscurin; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Obscurin, approximately 800 kDa in size, is one of three giant proteins expressed in vetebrate striated muscle, together with titin and nebulin. It is a multidomain protein composed of tandem adhesion and signaling domains, including 49 immunoglobulin (Ig) and 2 fibronectin type III (FN3) domains at the N-terminus followed by a more complex region containing more Ig domains, a conserved SH3 domain near a RhoGEF and PH domains, non-modular regions, as well as IQ and phosphorylation motifs. The obscurin gene also encode two kinase domains, which are not expressed as part of the 800 kDa protein, but as a smaller, alternatively spliced product present mainly in the heart muscle, also called obscurin-MLCK. Obscurin is localized at the peripheries of Z-disks and M-lines, where it is able to communicate with the surrounding myoplasm. It interacts with diverse proteins including sAnk1, myosin, titin, and MyBP-C. It may act as a scaffold for the assembly of elements of the contractile apparatus. The obscurin subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

112-164 2.20e-11

Src homology 3 domains of the p47phox subunit of NADPH oxidase and similar domains; This family is composed of the tandem SH3 domains of p47phox subunit of NADPH oxidase and Nox Organizing protein 1 (NoxO1), the four SH3 domains of Tks4 (Tyr kinase substrate with four SH3 domains), the five SH3 domains of Tks5, the SH3 domain of obscurin, Myosin-I, and similar domains. Most members of this group also contain Phox homology (PX) domains, except for obscurin and Myosin-I. p47phox and NoxO1 are regulators of the phagocytic NADPH oxidase complex (also called Nox2 or gp91phox) and nonphagocytic NADPH oxidase Nox1, respectively. They play roles in the activation of their respective NADPH oxidase, which catalyzes the transfer of electrons from NADPH to molecular oxygen to form superoxide. Tks proteins are Src substrates and scaffolding proteins that play important roles in the formation of podosomes and invadopodia, the dynamic actin-rich structures that are related to cell migration and cancer cell invasion. Obscurin is a giant muscle protein that plays important roles in the organization and assembly of the myofibril and the sarcoplasmic reticulum. Type I myosins (Myosin-I) are actin-dependent motors in endocytic actin structures and actin patches. They play roles in membrane traffic in endocytic and secretory pathways, cell motility, and mechanosensing. Myosin-I contains an N-terminal actin-activated ATPase, a phospholipid-binding TH1 (tail homology 1) domain, and a C-terminal extension which includes an F-actin-binding TH2 domain, an SH3 domain, and an acidic peptide that participates in activating the Arp2/3complex. The SH3 domain of myosin-I is required for myosin-I-induced actin polymerization. SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.

Pseudokinase domain of Scy1-like proteins; The pseudokinase domain shows similarity to protein kinases but lacks crucial residues for catalytic activity. This subfamily is composed of the catalytically inactive kinases with similarity to yeast Scy1. It includes four mammalian proteins called SCY1-like protein 1 (SCYL1), SCYL2, SCYL3, as well as Testis-EXpressed protein 14 (TEX14). SCYL1 binds to and co-localizes with the membrane trafficking coatomer I (COPI) complex, and regulates COPI-mediated vesicle trafficking. Null mutations in the SCYL1 gene are responsible for the pathology in mdf (muscle-deficient) mice which display progressive motor neuropathy. SCYL2, also called coated vesicle-associated kinase of 104 kDa (CVAK104), is involved in the trafficking of clathrin-coated vesicles. It also binds the HIV-1 accessory protein Vpu and acts as a regulatory factor that promotes the dephosphorylation of Vpu, facilitating the restriction of HIV-1 release. SCYL3, also called ezrin-binding protein PACE-1, may be involved in regulating cell adhesion and migration. TEX14 is required for spermatogenesis and male fertility. It localizes to kinetochores (KT) during mitosis and is a target of the mitotic kinase PLK1. It regulates the maturation of the outer KT and the KT-microtubule attachment. The SCY1-like subfamily is part of a larger superfamily that includes the catalytic domains of other protein serine/threonine kinases, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

253-495 2.35e-11

Catalytic domain of the Serine/Threonine Kinase, Rho-associated coiled-coil containing protein kinase 1; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. ROCK1 is preferentially expressed in the liver, lung, spleen, testes, and kidney. It mediates signaling from Rho to the actin cytoskeleton. It is implicated in the development of cardiac fibrosis, cardiomyocyte apoptosis, and hyperglycemia. Mice deficient with ROCK1 display eyelids open at birth (EOB) and omphalocele phenotypes due to the disorganization of actin filaments in the eyelids and the umbilical ring. ROCK contains an N-terminal extension, a catalytic kinase domain, and a C-terminal extension, which contains a coiled-coil region encompassing a Rho-binding domain (RBD) and a pleckstrin homology (PH) domain. ROCK is auto-inhibited by the RBD and PH domain interacting with the catalytic domain, and is activated via interaction with Rho GTPases. The ROCK1 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

291-547 2.41e-11

Catalytic domain of the Serine/Threonine Kinase, Mitogen-Activated Protein Kinase 15 and similar MAPKs; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. Human MAPK15 is also called Extracellular signal Regulated Kinase 8 (ERK8) while the rat protein is called ERK7. ERK7 and ERK8 display both similar and different biochemical properties. They autophosphorylate and activate themselves and do not require upstream activating kinases. ERK7 is constitutively active and is not affected by extracellular stimuli whereas ERK8 shows low basal activity and is activated by DNA-damaging agents. ERK7 and ERK8 also have different substrate profiles. Genome analysis shows that they are orthologs with similar gene structures. ERK7 and ERK 8 may be involved in the signaling of some nuclear receptor transcription factors. ERK7 regulates hormone-dependent degradation of estrogen receptor alpha while ERK8 down-regulates the transcriptional co-activation androgen and glucocorticoid receptors. MAPKs are important mediators of cellular responses to extracellular signals. The MAPK15 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of Serine/Threonine Kinase 16; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. STK16 is associated with many names including Myristylated and Palmitylated Serine/threonine Kinase 1 (MPSK1), Kinase related to cerevisiae and thaliana (Krct), and Protein Kinase expressed in day 12 fetal liver (PKL12). It is widely expressed in mammals with highest levels found in liver, testis, and kidney. It is localized in the Golgi but is translocated to the nucleus upon disorganization of the Golgi. STK16 is constitutively active and is capable of phosphorylating itself and other substrates. It may be involved in regulating stromal-epithelial interactions during mammary gland ductal morphogenesis. It may also function as a transcriptional co-activator of type-C natriuretic peptide and VEGF. The STK16 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

293-534 2.90e-11

Catalytic domain of the Wee1-like Protein Kinases; PKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine or tyrosine residues on protein substrates. This subfamily is composed of the dual-specificity kinase Myt1, the protein tyrosine kinase Wee1, and similar proteins. These proteins are cell cycle checkpoint kinases that are involved in the regulation of cyclin-dependent kinase CDK1, the master engine for mitosis. CDK1 is kept inactivated through phosphorylation of N-terminal thr (T14 by Myt1) and tyr (Y15 by Myt1 and Wee1) residues. Mitosis progression is ensured through activation of CDK1 by dephoshorylation and inactivation of Myt1/Wee1. The Wee1-like subfamily is part of a larger superfamily that includes the catalytic domains of other protein serine/threonine PKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

294-486 2.97e-11

N-terminal catalytic domain of the Serine/Threonine Kinase, Mitogen and stress-activated kinase 1; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. MSK1 plays a role in the regulation of translational control and transcriptional activation. It phosphorylates the transcription factors, CREB and NFkB. It also phosphorylates the nucleosomal proteins H3 and HMG-14. Increased phosphorylation of MSK1 is associated with the development of cerebral ischemic/hypoxic preconditioning. MSKs contain an N-terminal kinase domain (NTD) from the AGC family and a C-terminal kinase domain (CTD) from the CAMK family. MSKs are activated by two major signaling cascades, the Ras-MAPK and p38 stress kinase pathways, which trigger phosphorylation in the activation loop (A-loop) of the CTD of MSK. The active CTD phosphorylates the hydrophobic motif (HM) of NTD, which facilitates the phosphorylation of the A-loop and activates the NTD, which in turn phosphorylates downstream targets. The MSK1 subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

168-247 3.64e-11

Src homology 2 domain found in dual adaptor for phosphotyrosine and 3-phosphoinositides ( DAPP1)/B lymphocyte adaptor molecule of 32 kDa (Bam32)-like proteins; DAPP1/Bam32 contains a putative myristoylation site at its N-terminus, followed by a SH2 domain, and a pleckstrin homology (PH) domain at its C-terminus. DAPP1 could potentially be recruited to the cell membrane by any of these domains. Its putative myristoylation site could facilitate the interaction of DAPP1 with the lipid bilayer. Its SH2 domain may also interact with phosphotyrosine residues on membrane-associated proteins such as activated tyrosine kinase receptors. And finally its PH domain exhibits a high-affinity interaction with the PtdIns(3,4,5)P(3) PtdIns(3,4)P(2) second messengers produced at the cell membrane following the activation of PI 3-kinases. DAPP1 is thought to interact with both tyrosine phosphorylated proteins and 3-phosphoinositides and therefore may play a role in regulating the location and/or activity of such proteins(s) in response to agonists that elevate PtdIns(3,4,5)P(3) and PtdIns(3,4)P(2). This protein is likely to play an important role in triggering signal transduction pathways that lie downstream from receptor tyrosine kinases and PI 3-kinase. It is likely that DAPP1 functions as an adaptor to recruit other proteins to the plasma membrane in response to extracellular signals. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

294-501 3.86e-11

Catalytic domain of Suppressor of loss of cAMP-dependent protein kinase-like Serine/Threonine Kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. This subfamily is composed of Schizosaccharomyces pombe Sck1 and similar fungal proteins. Sck1 plays a role in trehalase activation triggered by glucose and a nitrogen source. Trehalase catalyzes the cleavage of the disaccharide trehalose to glucose. Trehalose, as a carbohydrate reserve and stress metabolite, plays an important role in the response of yeast to environmental changes. The Sck1-like subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

173-250 4.15e-11

Src homology 2 domain found in SH2 domain-containing adapter proteins D (SHD); The expression of SHD is restricted to the brain. SHD may be a physiological substrate of c-Abl and may function as an adapter protein in the central nervous system. It is also thought to be involved in apoptotic regulation. SHD contains five YXXP motifs, a substrate sequence preferred by Abl tyrosine kinases, in addition to a poly-proline rich region and a C-terminal SH2 domain. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

167-222 5.47e-11

Src homology 2 (SH2) domain found in suppressor of cytokine signaling (SOCS) proteins; SH2 domain found in SOCS proteins. SOCS was first recognized as a group of cytokine-inducible SH2 (CIS) domain proteins comprising eight family members in human (CIS and SOCS1-SOCS7). In addition to the SH2 domain, SOCS proteins have a variable N-terminal domain and a conserved SOCS box in the C-terminal domain. SOCS proteins bind to a substrate via their SH2 domain. The prototypical members, CIS and SOCS1-SOCS3, have been shown to regulate growth hormone signaling in vitro and in a classic negative feedback response compete for binding at phosphotyrosine sites in JAK kinase and receptor pathways to displace effector proteins and target bound receptors for proteasomal degradation. Loss of SOCS activity results in excessive cytokine signaling associated with a variety of hematopoietic, autoimmune, and inflammatory diseases and certain cancers. Members (SOCS4-SOCS7) were identified by their conserved SOCS box, an adapter motif of 3 helices that associates substrate binding domains, such as the SOCS SH2 domain, ankryin, and WD40 with ubiquitin ligase components. These show limited cytokine induction. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

297-534 6.02e-11

Catalytic domain of the Serine/Threonine protein kinase, cyclin G-Associated Kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. GAK, also called auxilin-2, contains an N-terminal kinase domain that phosphorylates the mu subunits of adaptor protein (AP) 1 and AP2. In addition, it contains an auxilin-1-like domain structure consisting of PTEN-like, clathrin-binding, and J domains. Like auxilin-1, GAK facilitates Hsc70-mediated dissociation of clathrin from clathrin-coated vesicles. GAK is expressed ubiquitously and is enriched in the Golgi, unlike auxilin-1 which is nerve-specific. GAK also plays regulatory roles outside of clathrin-mediated membrane traffic including the maintenance of centrosome integrity and chromosome congression, neural patterning, survival of neurons, and immune responses through interaction with the interleukin 12 receptor. It also interacts with the androgen receptor, acting as a transcriptional coactivator, and its expression is significantly increased with the progression of prostate cancer. The GAK subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine kinase, Inositol-requiring protein 1; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. IRE1, also called Endoplasmic reticulum (ER)-to-nucleus signaling protein (or ERN), is an ER-localized type I transmembrane protein with kinase and endoribonuclease domains in the cytoplasmic side. It acts as an ER stress sensor and is the oldest and most conserved component of the unfolded protein response (UPR) in eukaryotes. The UPR is activated when protein misfolding is detected in the ER in order to decrease the synthesis of new proteins and increase the capacity of the ER to cope with the stress. During ER stress, IRE1 dimerizes and forms oligomers, allowing the kinase domain to undergo trans-autophosphorylation. This leads to a conformational change that stimulates its endoribonuclease activity and results in the cleavage of its mRNA substrate, HAC1 in yeast and XBP1 in metazoans, promoting a splicing event that enables translation into a transcription factor which activates the UPR. Mammals contain two IRE1 proteins, IRE1alpha (or ERN1) and IRE1beta (or ERN2). The Ire1 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of the Serine/Threonine Kinase, Citron Rho-interacting kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. CRIK (also called citron kinase) is an effector of the small GTPase Rho. It plays an important function during cytokinesis and affects its contractile process. CRIK-deficient mice show severe ataxia and epilepsy as a result of abnormal cytokinesis and massive apoptosis in neuronal precursors. A Down syndrome critical region protein TTC3 interacts with CRIK and inhibits CRIK-dependent neuronal differentiation and neurite extension. CRIK contains a catalytic domain, a central coiled-coil domain, and a C-terminal region containing a Rho-binding domain (RBD), a zinc finger, and a pleckstrin homology (PH) domain, in addition to other motifs. The CRIK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

111-164 8.48e-11

Src homology 3 domain of Fyn and Yrk Protein Tyrosine Kinases; Fyn and Yrk (Yes-related kinase) are members of the Src subfamily of proteins, which are cytoplasmic (or non-receptor) PTKs. Fyn, together with Lck, plays a critical role in T-cell signal transduction by phosphorylating ITAM (immunoreceptor tyr activation motif) sequences on T-cell receptors, ultimately leading to the proliferation and differentiation of T-cells. In addition, Fyn is involved in the myelination of neurons, and is implicated in Alzheimer's and Parkinson's diseases. Yrk has been detected only in chickens. It is primarily found in neuronal and epithelial cells and in macrophages. It may play a role in inflammation and in response to injury. Src kinases contain an N-terminal SH4 domain with a myristoylation site, followed by SH3 and SH2 domains, a tyr kinase domain, and a regulatory C-terminal region containing a conserved tyr. They are activated by autophosphorylation at the tyr kinase domain, but are negatively regulated by phosphorylation at the C-terminal tyr by Csk (C-terminal Src Kinase). The SH3 domain of Src kinases contributes to substrate recruitment by binding adaptor proteins/substrates, and regulation of kinase activity through an intramolecular interaction. SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.

291-495 8.83e-11

The catalytic domain of the Serine/Threonine Kinase, Death-associated protein kinase-Related Apoptosis-inducing protein Kinase 2; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. DRAKs were named based on their similarity (around 50% identity) to the kinase domain of DAPKs. They contain an N-terminal kinase domain and a C-terminal regulatory domain. Vertebrates contain two subfamily members, DRAK1 and DRAK2 (also called STK17B). Both DRAKs are localized to the nucleus, autophosphorylate themselves, and phosphorylate myosin light chain as a substrate. DRAK2 has been implicated in inducing or enhancing apoptosis in beta cells, fibroblasts, and lymphoid cells, where it is highly expressed. It is involved in regulating many immune processes including the germinal center (GC) reaction, responses to thymus-dependent antigens, activated T cell survival, memory T cell responses. It may be involved in the development of autoimmunity. The DRAK2 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

292-539 1.18e-10

Catalytic domain of the Serine/Threonine kinase, Proviral Integration Moloney virus (PIM) kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. The PIM gene locus was discovered as a result of the cloning of retroviral intergration sites in murine Moloney leukemia virus, leading to the identification of PIM kinases. They are constitutively active STKs with a broad range of cellular targets and are overexpressed in many haematopoietic malignancies and solid cancers. Vertebrates contain three distinct PIM kinase genes (PIM1-3); each gene may result in mutliple protein isoforms. There are two PIM1 and three PIM2 isoforms as a result of alternative translation initiation sites, while there is only one PIM3 protein. Compound knockout mice deficient of all three PIM kinases that survive the perinatal period show a profound reduction in body size, indicating that PIMs are important for body growth. The PIM subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

169-262 1.21e-10

Src homology 2 (SH2) domain found in SLAM-associated protein (SAP) 1a; The X-linked lymphoproliferative syndrome (XLP) gene encodes SAP (also called SH2D1A/DSHP) a protein that consists of a 5 residue N-terminus, a single SH2 domain, and a short 25 residue C-terminal tail. XLP is characterized by an extreme sensitivity to Epstein-Barr virus. Both T and natural killer (NK) cell dysfunctions have been seen in XLP patients. SAP binds the cytoplasmic tail of Signaling lymphocytic activation molecule (SLAM), 2B4, Ly-9, and CD84. SAP is believed to function as a signaling inhibitor, by blocking or regulating binding of other signaling proteins. SAP and the SAP-like protein EAT-2 recognize the sequence motif TIpYXX[VI], which is found in the cytoplasmic domains of a restricted number of T, B, and NK cell surface receptors and are proposed to be natural inhibitors or regulators of the physiological role of a small family of receptors on the surface of these cells. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

112-161 1.27e-10

Src Homology 3 domain superfamily; Src Homology 3 (SH3) domains are protein interaction domains that bind proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. Thus, they are referred to as proline-recognition domains (PRDs). SH3 domains are less selective and show more diverse specificity compared to other PRDs. They have been shown to bind peptide sequences that lack the PxxP motif; examples include the PxxDY motif of Eps8 and the RKxxYxxY sequence in SKAP55. SH3 domain containing proteins play versatile and diverse roles in the cell, including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies, among others. Many members of this superfamily are adaptor proteins that associate with a number of protein partners, facilitating complex formation and signal transduction.

166-265 1.57e-10

Src homology 2 domain found in cancer-related signaling adaptor protein CRK; SH2 domain in the CRK proteins. CRKI (SH2-SH3) and CRKII (SH2-SH3-SH3) are splicing isoforms of the oncoprotein CRK. CRKs regulate transcription and cytoskeletal reorganization for cell growth and motility by linking tyrosine kinases to small G proteins. The SH2 domain of CRK associates with tyrosine-phosphorylated receptors or components of focal adhesions, such as p130Cas and paxillin. CRK transmits signals to small G proteins through effectors that bind its SH3 domain, such as C3G, the guanine-nucleotide exchange factor (GEF) for Rap1 and R-Ras, and DOCK180, the GEF for Rac6. The binding of p130Cas to the CRK-C3G complex activates Rap1, leading to regulation of cell adhesion, and activates R-Ras, leading to JNK-mediated activation of cell proliferation, whereas the binding of CRK DOCK180 induces Rac1-mediated activation of cellular migration. The activity of the different splicing isoforms varies greatly with CRKI displaying substantial transforming activity, CRKII less so, and phosphorylated CRKII with no biological activity whatsoever. CRKII has a linker region with a phosphorylated Tyr and an additional C-terminal SH3 domain. The phosphorylated Tyr creates a binding site for its SH2 domain which disrupts the association between CRK and its SH2 target proteins. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

166-262 1.72e-10

Src homology 2 (SH2) domain found in Tec protein, IL2-inducible T-cell kinase (Itk); A member of the Tec protein tyrosine kinase Itk is expressed thymus, spleen, lymph node, T lymphocytes, NK and mast cells. It plays a role in T-cell proliferation and differentiation, analogous to Tec family kinases Txk. Itk has been shown to interact with Fyn, Wiskott-Aldrich syndrome protein, KHDRBS1, PLCG1, Lymphocyte cytosolic protein 2, Linker of activated T cells, Karyopherin alpha 2, Grb2, and Peptidylprolyl isomerase A. Most of the Tec family members have a PH domain (Txk and the short (type 1) splice variant of Drosophila Btk29A are exceptions), a Tec homology (TH) domain, a SH3 domain, a SH2 domain, and a protein kinase catalytic domain. The TH domain consists of a Zn2+-binding Btk motif and a proline-rich region. The Btk motif is found in Tec kinases, Ras GAP, and IGBP. It is crucial for the function of Tec PH domains and it's lack of presence in Txk is not surprising since it lacks a PH domain. The type 1 splice form of the Drosophila homolog also lacks both the PH domain and the Btk motif. The proline-rich regions are highly conserved for the most part with the exception of Bmx whose residues surrounding the PXXP motif are not conserved (TH-like) and Btk29A which is entirely unique with large numbers of glycine residues (TH-extended). Tec family members all lack a C-terminal tyrosine having an autoinhibitory function in its phosphorylated state. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.
