 122-313 5.53e-139

Synaptic Ras-GTPase activating protein Pleckstrin homology (PH) domain; SynGAP is a member of the RasSynGAP family along with DOC-2/DAB2-interacting protein (DAB2IP) and neuronal growth-associated protein (nGAP/RASAL2). SynGAP, a neuronal Ras-GAP, has been shown display both Ras-GAP activity and Ras-related protein (Rap)-GAP activity. Saccharomyces cerevisiae Bud2 and GAP1 members CAPRI (Ca2+-promoted Ras inactivator) and RASAL (Ras-GTPase-activating-like protein) also possess this dual activity. Human DOC-2/DAB2-interacting protein (DAB2IP) is encoded by a tumor suppressor gene and a newly recognized member of the Ras-GTPase-activating family. Members here include mammals, amphibians, and bony fish. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

 252-414 1.63e-68

C2 domain present in Ras GTPase activating protein (GAP) family; SynGAP, GAP1, RasGAP, and neurofibromin are all members of the Ras-specific GAP (GTPase-activating protein) family. SynGAP regulates the MAP kinase signaling pathway and is critical for cognition and synapse function. Mutations in this gene causes mental retardation in humans. SynGAP contains a PH-like domain, a C2 domain, and a Ras-GAP domain. C2 domains fold into an 8-standed beta-sandwich that can adopt 2 structural arrangements: Type I and Type II, distinguished by a circular permutation involving their N- and C-terminal beta strands. Many C2 domains are Ca2+-dependent membrane-targeting modules that bind a wide variety of substances including bind phospholipids, inositol polyphosphates, and intracellular proteins. Most C2 domain proteins are either signal transduction enzymes that contain a single C2 domain, such as protein kinase C, or membrane trafficking proteins which contain at least two C2 domains, such as synaptotagmin 1. However, there are a few exceptions to this including RIM isoforms and some splice variants of piccolo/aczonin and intersectin which only have a single C2 domain. C2 domains with a calcium binding region have negatively charged residues, primarily aspartates, that serve as ligands for calcium ions.

 122-313 5.53e-139

Synaptic Ras-GTPase activating protein Pleckstrin homology (PH) domain; SynGAP is a member of the RasSynGAP family along with DOC-2/DAB2-interacting protein (DAB2IP) and neuronal growth-associated protein (nGAP/RASAL2). SynGAP, a neuronal Ras-GAP, has been shown display both Ras-GAP activity and Ras-related protein (Rap)-GAP activity. Saccharomyces cerevisiae Bud2 and GAP1 members CAPRI (Ca2+-promoted Ras inactivator) and RASAL (Ras-GTPase-activating-like protein) also possess this dual activity. Human DOC-2/DAB2-interacting protein (DAB2IP) is encoded by a tumor suppressor gene and a newly recognized member of the Ras-GTPase-activating family. Members here include mammals, amphibians, and bony fish. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

 252-414 1.63e-68

C2 domain present in Ras GTPase activating protein (GAP) family; SynGAP, GAP1, RasGAP, and neurofibromin are all members of the Ras-specific GAP (GTPase-activating protein) family. SynGAP regulates the MAP kinase signaling pathway and is critical for cognition and synapse function. Mutations in this gene causes mental retardation in humans. SynGAP contains a PH-like domain, a C2 domain, and a Ras-GAP domain. C2 domains fold into an 8-standed beta-sandwich that can adopt 2 structural arrangements: Type I and Type II, distinguished by a circular permutation involving their N- and C-terminal beta strands. Many C2 domains are Ca2+-dependent membrane-targeting modules that bind a wide variety of substances including bind phospholipids, inositol polyphosphates, and intracellular proteins. Most C2 domain proteins are either signal transduction enzymes that contain a single C2 domain, such as protein kinase C, or membrane trafficking proteins which contain at least two C2 domains, such as synaptotagmin 1. However, there are a few exceptions to this including RIM isoforms and some splice variants of piccolo/aczonin and intersectin which only have a single C2 domain. C2 domains with a calcium binding region have negatively charged residues, primarily aspartates, that serve as ligands for calcium ions.

Pleckstrin homology domain; Domain commonly found in eukaryotic signalling proteins. The domain family possesses multiple functions including the abilities to bind inositol phosphates, and various proteins. PH domains have been found to possess inserted domains (such as in PLC gamma, syntrophins) and to be inserted within other domains. Mutations in Brutons tyrosine kinase (Btk) within its PH domain cause X-linked agammaglobulinaemia (XLA) in patients. Point mutations cluster into the positively charged end of the molecule around the predicted binding site for phosphatidylinositol lipids.

chromosome segregation protein SMC, primarily archaeal type; SMC (structural maintenance of chromosomes) proteins bind DNA and act in organizing and segregating chromosomes for partition. SMC proteins are found in bacteria, archaea, and eukaryotes. It is found in a single copy and is homodimeric in prokaryotes, but six paralogs (excluded from this family) are found in eukarotes, where SMC proteins are heterodimeric. This family represents the SMC protein of archaea and a few bacteria (Aquifex, Synechocystis, etc); the SMC of other bacteria is described by TIGR02168. The N- and C-terminal domains of this protein are well conserved, but the central hinge region is skewed in composition and highly divergent.

 1193-1244 5.13e-03

UDM1 (ubiquitin-dependent DSB recruitment module 1) domain found in RING finger protein 168; RING finger protein 168 (RNF168) is an E3 ubiquitin-protein ligase that promotes noncanonical K27 ubiquitination to signal DNA damage. Together with RNF8, RNF168 functions as a DNA damage response (DDR) factor that promotes a series of ubiquitylation events on substrates such as H2A and H2AX. With H2AK13/15 ubiquitylation, it facilitates recruitment of repair factors p53-binding protein 1 (53BP1) or the RAP80-BRCA1 complex to sites of double-strand breaks (DSBs), and inhibits homologous recombination (HR) in cells deficient in the tumor suppressor BRCA1. RNF168 also promotes H2A neddylation, which antagonizes ubiquitylation of H2A and regulates DNA damage repair. In addition, RNF168 forms a functional complex with RAD6A or RAD6B during the DNA damage response. This model corresponds to the UDM1 (ubiquitin-dependent double-strand break [DSB] recruitment module 1) domain of RNF168, which comprises LRM1 (LR motif 1), UMI (ubiquitin-interacting motif [UIM]- and MIU-related UBD) and MIU1 (motif interacting with ubiquitin 1). Mutations of Ub-interacting residues in UDM1 have little effect on the accumulation of RNF168 to DSB sites, suggesting that it may not be the main site of binding ubiquitylated and polyubiquitylated targets.

 122-313 5.53e-139

Synaptic Ras-GTPase activating protein Pleckstrin homology (PH) domain; SynGAP is a member of the RasSynGAP family along with DOC-2/DAB2-interacting protein (DAB2IP) and neuronal growth-associated protein (nGAP/RASAL2). SynGAP, a neuronal Ras-GAP, has been shown display both Ras-GAP activity and Ras-related protein (Rap)-GAP activity. Saccharomyces cerevisiae Bud2 and GAP1 members CAPRI (Ca2+-promoted Ras inactivator) and RASAL (Ras-GTPase-activating-like protein) also possess this dual activity. Human DOC-2/DAB2-interacting protein (DAB2IP) is encoded by a tumor suppressor gene and a newly recognized member of the Ras-GTPase-activating family. Members here include mammals, amphibians, and bony fish. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

DOC-2/Disabled homolog 2-interacting protein Pleckstrin homology (PH) domain; DAB2IP (also called AIP1/ASK1-interacting protein-1 and DIP1/2) is a member of the RasSynGAP family along with Synaptic Ras-GTPase activating protein (SynGAP) and neuronal growth-associated protein (nGAP/RASAL2). DAB2IP is a critical component of many signal transduction pathways mediated by Ras and tumor necrosis factors including apoptosis pathways, and it is involved in the formation of many types of tumors. DAB2IP participates in regulation of gene expression and pluripotency of cells. Human DAB2IP is expressed in the adrenal gland, pancreas, endocardium, stomach, kidney, testis, small intestine, liver, trachea, skin, ovary, endometrium, lung, esophagus and bladder. No expression was observed in the cerebrum, parotid gland, thymus, thyroid gland and spleen. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

Ras GTPase Activating Domain; RasGAP functions as an enhancer of the hydrolysis of GTP that is bound to Ras-GTPases. Proteins having a RasGAP domain include p120GAP, IQGAP, Rab5-activating protein 6, and Neurofibromin, among others. Although the Rho (Ras homolog) GTPases are most closely related to members of the Ras family, RhoGAP and RasGAP exhibit no similarity at their amino acid sequence level. RasGTPases function as molecular switches in a large number of signaling pathways. They are in the on state when bound to GTP, and in the off state when bound to GDP. The RasGAP domain speeds up the hydrolysis of GTP in Ras-like proteins acting as a negative regulator.

 252-414 1.63e-68

C2 domain present in Ras GTPase activating protein (GAP) family; SynGAP, GAP1, RasGAP, and neurofibromin are all members of the Ras-specific GAP (GTPase-activating protein) family. SynGAP regulates the MAP kinase signaling pathway and is critical for cognition and synapse function. Mutations in this gene causes mental retardation in humans. SynGAP contains a PH-like domain, a C2 domain, and a Ras-GAP domain. C2 domains fold into an 8-standed beta-sandwich that can adopt 2 structural arrangements: Type I and Type II, distinguished by a circular permutation involving their N- and C-terminal beta strands. Many C2 domains are Ca2+-dependent membrane-targeting modules that bind a wide variety of substances including bind phospholipids, inositol polyphosphates, and intracellular proteins. Most C2 domain proteins are either signal transduction enzymes that contain a single C2 domain, such as protein kinase C, or membrane trafficking proteins which contain at least two C2 domains, such as synaptotagmin 1. However, there are a few exceptions to this including RIM isoforms and some splice variants of piccolo/aczonin and intersectin which only have a single C2 domain. C2 domains with a calcium binding region have negatively charged residues, primarily aspartates, that serve as ligands for calcium ions.

 130-260 8.02e-54

Synaptic Ras-GTPase activating protein family Pleckstrin homology (PH) domain; The RasSynGAP family is composed of members: DAB2IP, nGAP, and SynGAP. Neuronal growth-associated proteins (nGAPs) are growth cone markers found in multiple types of neurons. There are many nGAPs including Cap1 (Adenylate cyclase-associated protein 1), Capzb (Capping protein (actin filament) muscle Z-line, beta), Clptm1 (Cleft lip and palate associated transmembrane protein 1), Cotl1 (Coactosin-like 1), Crmp1 (Collapsin response mediator protein 1), Cyfip1 (Cytoplasmic FMR1 interacting protein 1), Fabp7 (Fatty acid binding protein 7, brain), Farp2 (FERM, RhoGEF and pleckstrin domain protein 2), Gap43 (Growth associated protein 43), Gnao1 (Guanine nucleotide binding protein (G protein), alpha activating activity polypeptide O), Gnai2 (Guanine nucleotide binding protein (G protein), alpha inhibiting 2), Pacs1 (Phosphofurin acidic cluster sorting protein 1), Rtn1 (Reticulon 1), Sept2 (Septin 2), Snap25 (Synaptosomal-associated protein 25), Strap (Serine/threonine kinase receptor associated protein), Stx7 (Syntaxin 7), and Tmod2 (Tropomodulin 2). SynGAP, a neuronal Ras-GAP, has been shown display both Ras-GAP activity and Ras-related protein (Rap)-GAP activity. Saccharomyces cerevisiae Bud2 and GAP1 members CAPRI (Ca2+-promoted Ras inactivator) and RASAL (Ras-GTPase-activating-like protein) also possess this dual activity. Human DOC-2/DAB2-interacting protein (DAB2IP) is encoded by a tumor suppressor gene and a newly recognized member of the Ras-GTPase-activating family. DAB2IP is a critical component of many signal transduction pathways mediated by Ras and tumor necrosis factors including apoptosis pathways, and it is involved in the formation of many types of tumors. DAB2IP participates in regulation of gene expression and pluripotency of cells. It has been reported that DAB2IP was expressed in different tumor tissues. Little information is available concerning the expression levels of DAB2IP in normal tissues and cells, however, and no studies of its expression patterns during the development of human embryos have been reported. DAB2IP was expressed primarily in cell cytoplasm throughout the fetal development. The expression levels varied among tissues and different gestational ages. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

Ras-GTPase Activating Domain of CLA2/BUD2; CLA2/BUD2 functions as a GTPase-activating protein (GAP) for BUD1/RSR1 and is necessary for proper bud-site selection in yeast. BUD2 has sequence similarity to the catalytic domain of RasGAPs, and stimulates the hydrolysis of BUD1-GTP to BUD1-GDP. Elimination of Bud2p activity by mutation causes a random budding pattern with no growth defect. Overproduction of Bud2p also alters the budding pattern.

Ras-GTPase Activating Domain of GAP1 and similar proteins; The GAP1 family of Ras GTPase-activating proteins includes GAP1(m) (or RASA2), GAP1_IP4BP (or RASA3), Ca2+ -promoted Ras inactivator (CAPRI, or RASAL4), and Ras GTPase activating-like proteins (RASAL) or RASAL1. The members are characterized by a conserved domain structure comprising N-terminal tandem C2 domains, a highly conserved central RasGAP domain, and a C-terminal pleckstrin homology domain that is associated with a Bruton's tyrosine kinase motif. While this domain structure is conserved, a small change in the function of each individual domain and the interaction between domains has a marked effect on the regulation of each protein.

Ras-GTPase Activating Domain of proteins similar to neurofibromin; Neurofibromin-like proteins include the Saccharomyces cerevisiae RasGAP proteins Ira1 and Ira2, the closest homolog of neurofibromin, which is responsible for the human autosomal dominant disease neurofibromatosis type I (NF1). The RasGAP Ira1/2 proteins are negative regulators of the Ras-cAMP signaling pathway and conserved from yeast to human. In yeast Ras proteins are activated by GEFs, and inhibited by two GAPs, Ira1 and Ira2. Ras proteins activate the cAMP/protein kinase A (PKA) pathway, which controls metabolism, stress resistance, growth, and meiosis. Recent studies showed that the kelch proteins Gpb1 and Gpb2 inhibit Ras activity via association with Ira1 and Ira2. Gpb1/2 bind to a conserved C-terminal domain of Ira1/2, and loss of Gpb1/2 results in a destabilization of Ira1 and Ira2, leading to elevated levels of Ras2-GTP and uninhibited cAMP-PKA signaling. Since the Gpb1/2 binding domain on Ira1/2 is conserved in the human neurofibromin protein, the studies suggest that an analogous signaling mechanism may contribute to the neoplastic development of NF1.

 444-669 1.69e-36

Ras-GTPase Activating Domain of RASA3; RASA3 (or GAP1_IP4BP) is a member of the GAP1 family and has been shown to specifically bind 1,3,4,5-tetrakisphosphate (IP4). Thus, RASA3 may function as an IP4 receptor. The members of GAP1 family are characterized by a conserved domain structure comprising N-terminal tandem C2 domains, a highly conserved central RasGAP domain, and a C-terminal pleckstrin-homology domain that is associated with a Bruton's tyrosine kinase motif. Purified RASA3 stimulates GAP activity on Ras with about a five-fold lower potency than p120RasGAP, but shows no GAP-stimulating activity at all against Rac or Rab3A.

 411-718 6.07e-34

Ras-GTPase Activating Domain of p120; p120GAP is a negative regulator of Ras that stimulates hydrolysis of bound GTP to GDP. Once the Ras regulator p120GAP, a member of the GAP protein family, is recruited to the membrane, it is transiently immobilized to interact with Ras-GTP. The down-regulation of Ras by p120GAP is a critical step in the regulation of many cellular processes, which is disrupted in approximately 30% of human cancers. p120GAP contains SH2, SH3, PH, calcium- and lipid-binding domains, suggesting its involvement in a complex network of cellular interactions in vivo.

 433-671 7.79e-30

Ras-GTPase Activating Domain of RASAL1 and similar proteins; Ras GTPase activating-like protein (RASAL) or RASAL1 is a member of the GAP1 family, and a Ca2+ sensor responding in-phase to repetitive Ca2+ signals by associating with the plasma membrane and deactivating Ras. It contains a conserved domain structure comprising N-terminal tandem C2 domains, a highly conserved central RasGAP domain, and a C-terminal pleckstrin-homology domain that is associated with a Bruton's tyrosine kinase motif. RASAL, like Ca2+ -promoted Ras inactivator (CAPRI, or RASAL4), is a cytosolic protein that undergoes a rapid translocation to the plasma membrane in response to receptor-mediated elevation in the concentration of intracellular free Ca2+, a translocation that activates its ability to function as a RasGAP. However, unlike RASAL4, RASAL undergoes an oscillatory translocation to the plasma membrane that occurs in synchrony with repetitive Ca2+ spikes.

Ras-GTPase Activating Domain of RASA2; RASA2 (or GAP1(m)) is a member of the GAP1 family of Ras GTPase-activating proteins that includes GAP1_IP4BP (or RASA3), CAPRI, and RASAL. In vitro, RASA2 has been shown to bind inositol 1,3,4,5-tetrakisphosphate (IP4), the water soluble inositol head group of the lipid second messenger phosphatidylinositol 3,4,5-trisphosphate (PIP3). In vivo studies also demonstrated that RASA2 binds PIP3, and it is recruited to the plasma membrane following agonist stimulation of PI 3-kinase. Furthermore, the membrane translocation is a consequence of the ability of its pleckstrin homology (PH) domain to bind PIP3.

 157-275 5.50e-26

RAS protein activator like-3 Pleckstrin homology (PH) domain; RASAL3 is thought to be a Ras GTPase-activating protein. It is involved in positive regulation of Ras GTPase activity and of small GTPase mediated signal transduction as well as negative regulation of Ras protein signal transduction. It contains a PH domain, a C2 domain, and a Ras-GAP domain. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

 446-698 3.06e-23

Ras-GTPase Activating Domain of neurofibromin; Neurofibromin is the product of the neurofibromatosis type 1 gene (NF1) and shares a region of similarity with catalytic domain of the mammalian p120RasGAP protein and an extended similarity with the Saccharomyces cerevisiae RasGAP proteins Ira1 and Ira2. Neurofibromin has been shown to function as a GAP (GTPase-activating protein) which inhibits low molecular weight G proteins such as Ras by stimulating their intrinsic GTPase activity. NF1 is a common genetic disorder characterized by various symptoms ranging from predisposition for the development of tumors to learning disability or mental retardation. Loss of neurofibromin activity can be correlated to the increase in Ras-GTP concentration in neurofibromas of NF1 of patients, supporting the notion that unregulated Ras signaling may contribute to their development.

 485-718 3.89e-22

Ras-GTPase Activating Domain of GAPA; GAPA is an IQGAP-related protein and is predicted to bind to small GTPases, which are yet to be identified. IQGAP proteins are integral components of cytoskeletal regulation. Results from truncated GAPAs indicated that almost the entire region of GAPA homologous to IQGAP is required for cytokinesis in Dictyostelium. More members of the IQGAP family are emerging, and evidence suggests that there are both similarities and differences in their function.

 431-642 1.31e-21

Ras-GTPase Activating Domain of RASA4; Ras GTPase activating-like 4 protein (RASAL4), also known as Ca2+ -promoted Ras inactivator (CAPRI), is a member of the GAP1 family. Members of the GAP1 family are characterized by a conserved domain structure comprising N-terminal tandem C2 domains, a highly conserved central RasGAP domain, and a C-terminal pleckstrin-homology domain that is associated with a Bruton's tyrosine kinase motif. RASAL4, like RASAL, is a cytosolic protein that undergoes a rapid translocation to the plasma membrane in response to a receptor-mediated elevation in the concentration of intracellular free Ca2+ ([Ca2+]i). However, unlike RASAL, RASAL4 does not sense oscillations in [Ca2+]i.

 472-721 4.76e-07

Ras-GTPase Activating Domain of IQ motif containing GTPase activating proteins; This family represents IQ motif containing GTPase activating protein (IQGAP) which associated with the Ras GTP-binding protein. A primary function of IQGAP proteins is to modulate cytoskeletal architecture. There are three known IQGAP family members: IQGAP1, IQGAP2 and IQGAP3. Human IQGAP1 and IQGAP2 share 62% identity. IQGAPs are multi-domain molecules having a calponin-homology (CH) domain which binds F-actin, IQGAP-specific repeats, a single WW domain, four IQ motifs that mediate interactions with calmodulin, and a RasGAP related domain that binds active Rho family GTPases. IQGAP is an essential regulator of cytoskeletal function. IQGAP1 negatively regulates Ras family GTPases by stimulating their intrinsic GTPase activity, the protein actually lacks GAP activity. Both IQGAP1 and IQGAP2 specifically bind to Cdc42 and Rac1, but not to RhoA. Despite of their similarities to part of the sequence of RasGAP, neither IQGAP1 nor IQGAP2 interacts with Ras. IQGAP3, only present in mammals, regulates the organization of the cytoskeleton under the regulation of Rac1 and Cdc42 in neuronal cells. The depletion of IQGAP3 is shown to impair neurite or axon outgrowth in neuronal cells with disorganized cytoskeleton.

C2 domain; The C2 domain was first identified in PKC. C2 domains fold into an 8-standed beta-sandwich that can adopt 2 structural arrangements: Type I and Type II, distinguished by a circular permutation involving their N- and C-terminal beta strands. Many C2 domains are Ca2+-dependent membrane-targeting modules that bind a wide variety of substances including bind phospholipids, inositol polyphosphates, and intracellular proteins. Most C2 domain proteins are either signal transduction enzymes that contain a single C2 domain, such as protein kinase C, or membrane trafficking proteins which contain at least two C2 domains, such as synaptotagmin 1. However, there are a few exceptions to this including RIM isoforms and some splice variants of piccolo/aczonin and intersectin which only have a single C2 domain. C2 domains with a calcium binding region have negatively charged residues, primarily aspartates, that serve as ligands for calcium ions.

Pleckstrin homology domain; Domain commonly found in eukaryotic signalling proteins. The domain family possesses multiple functions including the abilities to bind inositol phosphates, and various proteins. PH domains have been found to possess inserted domains (such as in PLC gamma, syntrophins) and to be inserted within other domains. Mutations in Brutons tyrosine kinase (Btk) within its PH domain cause X-linked agammaglobulinaemia (XLA) in patients. Point mutations cluster into the positively charged end of the molecule around the predicted binding site for phosphatidylinositol lipids.

 473-729 3.74e-04

Ras-GTPase Activating Domain of IQ motif containing GTPase activating protein 2; IQGAP2 is a member of the IQGAP family that contains a calponin-homology (CH) domain which binds F-actin, IQGAP-specific repeat, a single WW domain, four IQ motifs which mediate interactions with calmodulin, and a Ras-GTPase-activating protein (GAP)-related domain that binds Rho family GTPases. IQGAP2 and IQGAP3 play important roles in the regulation of the cytoskeleton for axon outgrowth in hippocampal neurons and are thought to stay in a common regulatory pathway. The results of RNA interference studies indicated that IQGAP3 partially compensates functions of IQGAP2, but has lesser ability than IQGAP2 to promote axon outgrowth in hippocampal neuron. Moreover, IQGAP2 is required for the cadherin-mediated cell-to-cell adhesion in Xenopus laevis embryos.

SMC proteins are found in bacteria, archaea, and eukaryotes. It is found in a single copy and is homodimeric in prokaryotes, but six paralogs (excluded from this family) are found in eukarotes, where SMC proteins are heterodimeric. This family represents the SMC protein of archaea and a few bacteria (Aquifex, Synechocystis, etc); the SMC of other bacteria is described by TIGR02168. The N- and C-terminal domains of this protein are well conserved, but the central hinge region is skewed in composition and highly divergent.

 582-731 7.15e-04

Ras-GTPase Activating Domain of IQ motif containing GTPase activating protein 1; IQGAP1 is a homodimeric protein that is widely expressed among vertebrate cell types from early embryogenesis. Mammalian IQGAP1 protein is the best characterized member of the IQGAP family, and contains several protein-interacting domains. Human IQGAP1 is most similar to mouse Iqgap1 (94% identity) and has 62% identity to human IQGAP2. IQGAP1 binds and cross-links actin filaments in vitro and has been implicated in Ca2+/calmodulin signaling, E-cadherin-dependent cell adhesion, cell motility, and invasion. Yeast IQGAP homologs have a role in the recruitment of actin filaments, are components of the spindle pole body, and are required for actomyosin ring assembly and cytokinesis. Furthermore, IQGAP1 over-expression has also been detected in gastric and colorectal carcinomas and gastric cancer cell lines.

 1193-1244 5.13e-03

UDM1 (ubiquitin-dependent DSB recruitment module 1) domain found in RING finger protein 168; RING finger protein 168 (RNF168) is an E3 ubiquitin-protein ligase that promotes noncanonical K27 ubiquitination to signal DNA damage. Together with RNF8, RNF168 functions as a DNA damage response (DDR) factor that promotes a series of ubiquitylation events on substrates such as H2A and H2AX. With H2AK13/15 ubiquitylation, it facilitates recruitment of repair factors p53-binding protein 1 (53BP1) or the RAP80-BRCA1 complex to sites of double-strand breaks (DSBs), and inhibits homologous recombination (HR) in cells deficient in the tumor suppressor BRCA1. RNF168 also promotes H2A neddylation, which antagonizes ubiquitylation of H2A and regulates DNA damage repair. In addition, RNF168 forms a functional complex with RAD6A or RAD6B during the DNA damage response. This model corresponds to the UDM1 (ubiquitin-dependent double-strand break [DSB] recruitment module 1) domain of RNF168, which comprises LRM1 (LR motif 1), UMI (ubiquitin-interacting motif [UIM]- and MIU-related UBD) and MIU1 (motif interacting with ubiquitin 1). Mutations of Ub-interacting residues in UDM1 have little effect on the accumulation of RNF168 to DSB sites, suggesting that it may not be the main site of binding ubiquitylated and polyubiquitylated targets.
