349-570 9.88e-158

Regulator of G protein signaling (RGS) domain found in the leukemia-associated Rho guanine nucleotide exchange factor (RhoGEF) protein (LARG); The RGS domain is an essential part of the leukemia-associated RhoGEF protein (LARG), a member of the RhoGEF (Rho guanine nucleotide exchange factor) subfamily of the RGS protein family. The RhoGEFs are peripheral membrane proteins that regulate essential cellular processes, including cell shape, cell migration, cell cycle progression of cells, and gene transcription by linking signals from heterotrimeric G-alpha12/13 protein-coupled receptors to Rho GTPase activation, leading to various cellular responses, such as actin reorganization and gene expression. The RhoGEF subfamily includes p115RhoGEF, LARG, PDZ-RhoGEF, and its rat specific splice variant GTRAP48. The RGS domain of RhoGEFs has very little sequence similarity with the canonical RGS domain of the RGS proteins and is often refered to as RH (RGS Homology) domain. In addition to being a G-alpha13 effector, the LARG protein also functions as a GTPase-activating protein (GAP) for G-alpha13. RGS proteins play critical regulatory role as GTPase activating proteins (GAPs) of the heterotrimeric G-protein G-alpha-subunits. RGS proteins play critical regulatory role as GTPase activating proteins (GAPs) of the heterotrimeric G-protein G-alpha-subunits. RGS proteins regulate many aspects of embryonic development such as glial differentiation, embryonic axis formation, skeletal and muscle development, cell migration during early embryogenesis, as well as apoptosis, cell proliferation, and modulation of cardiac development.

Leukemia-associated Rho guanine nucleotide exchange factor Pleckstrin homology (PH) domain; ...
995-1132 4.45e-82

Leukemia-associated Rho guanine nucleotide exchange factor Pleckstrin homology (PH) domain; LARG (also called RhoGEF12) belongs to regulator of G-protein signaling (RGS) domain-containing RhoGEFs that are RhoA-selective and directly activated by the Galpha12/13 family of heterotrimeric G proteins. RhoGEFs activate Rho GTPases regulating cytoskeletal structure, gene transcription, and cell migration. LARG contains a N-terminal extension, followed by Dbl homology (DH)-PH domains which bind and catalyze the exchange of GDP for GTP on RhoA in addition to a RGS domain. The active site of RhoA adopts two distinct GDP-excluding conformations among the four unique complexes in the asymmetric unit. The LARG PH domain also contains a potential protein-docking site. LARG forms a homotetramer via its DH domains. 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.

70-145 5.31e-47

PDZ domain of ARHGEF11, ARHGEF12, and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of ARHGEF11, ARHGEF12, and related domains. This subfamily includes the GEFs (guanine exchange factors) ARHGEF11 (Rho guanine nucleotide exchange factor 11, known as PDZ-RhoGEF) and ARHGEF12 (Rho guanine nucleotide exchange factor 12, also known as leukemia-associated RhoGEF). GEFs activate Rho GTPases by promoting GTP binding. ARHGEF11/12 are regulators of G protein signaling (RGS) domain-containing GEFs; the RGS domain mediates their binding to and activation of Galpha (and Gq also in the case of ARHGEF12), in response to G-protein coupled receptor activation. ARHGEF11 and 12 are involved in serum-signaling, and regulate Yes-Associated Protein (YAP1)-dependent transcription. The ARHGEF12 PDZ domain binds plexin-B1 and the receptor tyrosine kinase insulin-like growth factor receptor (IGF-R1) beta-subunit. ARHGEF12 also interacts with glutamate receptor delta-1(GluD1), a postsynaptic organizer of inhibitory synapses in cortical pyramidal neurons. The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This ARHGEF11-12-like family domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2), arranged in the order: beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F.

368-558 1.38e-105

Regulator of G protein signalling-like domain; Members of this family adopt a structure consisting of twelve helices that fold into a compact domain that contains the overall structural scaffold observed in other RGS proteins and three additional helical elements that pack closely to it. Helices 1-9 comprise the RGS (pfam00615) fold, in which helices 4-7 form a classic antiparallel bundle adjacent to the other helices. Like other RGS structures, helices 7 and 8 span the length of the folded domain and form essentially one continuous helix with a kink in the middle. Helices 10-12 form an apparently stable C-terminal extension of the structural domain, and although other RGS proteins lack this structure, these elements are intimately associated with the rest of the structural framework by hydrophobic interactions. Members of the family bind to active G-alpha proteins, promoting GTP hydrolysis by the alpha subunit of heterotrimeric G proteins, thereby inactivating the G protein and rapidly switching off G protein-coupled receptor signalling pathways.

Leukemia-associated Rho guanine nucleotide exchange factor Pleckstrin homology (PH) domain; LARG (also called RhoGEF12) belongs to regulator of G-protein signaling (RGS) domain-containing RhoGEFs that are RhoA-selective and directly activated by the Galpha12/13 family of heterotrimeric G proteins. RhoGEFs activate Rho GTPases regulating cytoskeletal structure, gene transcription, and cell migration. LARG contains a N-terminal extension, followed by Dbl homology (DH)-PH domains which bind and catalyze the exchange of GDP for GTP on RhoA in addition to a RGS domain. The active site of RhoA adopts two distinct GDP-excluding conformations among the four unique complexes in the asymmetric unit. The LARG PH domain also contains a potential protein-docking site. LARG forms a homotetramer via its DH domains. 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.

PDZ domain of ARHGEF11, ARHGEF12, and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of ARHGEF11, ARHGEF12, and related domains. This subfamily includes the GEFs (guanine exchange factors) ARHGEF11 (Rho guanine nucleotide exchange factor 11, known as PDZ-RhoGEF) and ARHGEF12 (Rho guanine nucleotide exchange factor 12, also known as leukemia-associated RhoGEF). GEFs activate Rho GTPases by promoting GTP binding. ARHGEF11/12 are regulators of G protein signaling (RGS) domain-containing GEFs; the RGS domain mediates their binding to and activation of Galpha (and Gq also in the case of ARHGEF12), in response to G-protein coupled receptor activation. ARHGEF11 and 12 are involved in serum-signaling, and regulate Yes-Associated Protein (YAP1)-dependent transcription. The ARHGEF12 PDZ domain binds plexin-B1 and the receptor tyrosine kinase insulin-like growth factor receptor (IGF-R1) beta-subunit. ARHGEF12 also interacts with glutamate receptor delta-1(GluD1), a postsynaptic organizer of inhibitory synapses in cortical pyramidal neurons. The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This ARHGEF11-12-like family domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2), arranged in the order: beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F.

periplasmic serine protease, Do/DeqQ family; This family consists of a set proteins various designated DegP, heat shock protein HtrA, and protease DO. The ortholog in Pseudomonas aeruginosa is designated MucD and is found in an operon that controls mucoid phenotype. This family also includes the DegQ (HhoA) paralog in E. coli which can rescue a DegP mutant, but not the smaller DegS paralog, which cannot. Members of this family are located in the periplasm and have separable functions as both protease and chaperone. Members have a trypsin domain and two copies of a PDZ domain. This protein protects bacteria from thermal and other stresses and may be important for the survival of bacterial pathogens.// The chaperone function is dominant at low temperatures, whereas the proteolytic activity is turned on at elevated temperatures.

349-570 9.88e-158

Regulator of G protein signaling (RGS) domain found in the leukemia-associated Rho guanine nucleotide exchange factor (RhoGEF) protein (LARG); The RGS domain is an essential part of the leukemia-associated RhoGEF protein (LARG), a member of the RhoGEF (Rho guanine nucleotide exchange factor) subfamily of the RGS protein family. The RhoGEFs are peripheral membrane proteins that regulate essential cellular processes, including cell shape, cell migration, cell cycle progression of cells, and gene transcription by linking signals from heterotrimeric G-alpha12/13 protein-coupled receptors to Rho GTPase activation, leading to various cellular responses, such as actin reorganization and gene expression. The RhoGEF subfamily includes p115RhoGEF, LARG, PDZ-RhoGEF, and its rat specific splice variant GTRAP48. The RGS domain of RhoGEFs has very little sequence similarity with the canonical RGS domain of the RGS proteins and is often refered to as RH (RGS Homology) domain. In addition to being a G-alpha13 effector, the LARG protein also functions as a GTPase-activating protein (GAP) for G-alpha13. RGS proteins play critical regulatory role as GTPase activating proteins (GAPs) of the heterotrimeric G-protein G-alpha-subunits. RGS proteins play critical regulatory role as GTPase activating proteins (GAPs) of the heterotrimeric G-protein G-alpha-subunits. RGS proteins regulate many aspects of embryonic development such as glial differentiation, embryonic axis formation, skeletal and muscle development, cell migration during early embryogenesis, as well as apoptosis, cell proliferation, and modulation of cardiac development.

368-558 1.38e-105

Regulator of G protein signalling-like domain; Members of this family adopt a structure consisting of twelve helices that fold into a compact domain that contains the overall structural scaffold observed in other RGS proteins and three additional helical elements that pack closely to it. Helices 1-9 comprise the RGS (pfam00615) fold, in which helices 4-7 form a classic antiparallel bundle adjacent to the other helices. Like other RGS structures, helices 7 and 8 span the length of the folded domain and form essentially one continuous helix with a kink in the middle. Helices 10-12 form an apparently stable C-terminal extension of the structural domain, and although other RGS proteins lack this structure, these elements are intimately associated with the rest of the structural framework by hydrophobic interactions. Members of the family bind to active G-alpha proteins, promoting GTP hydrolysis by the alpha subunit of heterotrimeric G proteins, thereby inactivating the G protein and rapidly switching off G protein-coupled receptor signalling pathways.

995-1132 4.45e-82

Leukemia-associated Rho guanine nucleotide exchange factor Pleckstrin homology (PH) domain; LARG (also called RhoGEF12) belongs to regulator of G-protein signaling (RGS) domain-containing RhoGEFs that are RhoA-selective and directly activated by the Galpha12/13 family of heterotrimeric G proteins. RhoGEFs activate Rho GTPases regulating cytoskeletal structure, gene transcription, and cell migration. LARG contains a N-terminal extension, followed by Dbl homology (DH)-PH domains which bind and catalyze the exchange of GDP for GTP on RhoA in addition to a RGS domain. The active site of RhoA adopts two distinct GDP-excluding conformations among the four unique complexes in the asymmetric unit. The LARG PH domain also contains a potential protein-docking site. LARG forms a homotetramer via its DH domains. 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.

Regulator of G protein signaling (RGS) domain found in the Rho guanine nucleotide exchange factor (RhoGEF) protein; The RGS domain found in the Rho guanine nucleotide exchange factor (RhoGEF) protein subfamily of the RGS domain containing protein family, which is a diverse group of multifunctional proteins that regulate cellular signaling events downstream of G-protein coupled receptors (GPCRs). RhoGEFs link signals from heterotrimeric G-alpha12/13 protein-coupled receptors to Rho GTPase activation, leading to various cellular responses, such as actin reorganization and gene expression. The RGS domain of the RhoGEFs has very little sequence similarity with the canonical RGS domain of the RGS proteins and therefore is often refered to as the RH (RGS Homology) domain. The RGS-GEFs subfamily includes the leukemia-associated RhoGEF (LARG), p115RhoGEF, and PDZ-RhoGEF. RGS proteins play critical regulatory role as GTPase activating proteins (GAPs) of the heterotrimeric G-protein G-alpha-subunits. RGS proteins play critical regulatory role as GTPase activating proteins (GAPs) of the heterotrimeric G-protein G-alpha-subunits. RGS proteins regulate many aspects of embryonic development such as glial differentiation, embryonic axis formation, skeletal and muscle development, cell migration during early embryogenesis, as well as apoptosis, cell proliferation, and modulation of cardiac development.

Regulator of G protein signaling (RGS) domain found in the Rho guanine nucleotide exchange factor (GEF), p115 RhoGEF; The RGS (Regulator of G-protein Signaling) domain is an essential part of the p115RhoGEF protein, a member of the RhoGEF (Rho guanine nucleotide exchange factor) subfamily of the RGS protein family. The RhoGEFs are peripheral membrane proteins that regulate essential cellular processes, including cell shape, cell migration, cell cycle progression of cells, and gene transcription by linking signals from heterotrimeric G-alpha12/13 protein-coupled receptors to Rho GTPase activation, leading to various cellular responses, such as actin reorganization and gene expression. The RhoGEF subfamily includes p115RhoGEF, LARG, PDZ-RhoGEF and its rat specific splice variant GTRAP48. The RGS domain of RhoGEFs has very little sequence similarity with the canonical RGS domain of the RGS proteins and is often refered to as RH (RGS Homology) domain. In addition to being a G-alpha13/12 effector, the p115RhoGEF protein also functions as a GTPase-activating protein (GAP) for G-alpha13. RGS proteins play critical regulatory role as GTPase activating proteins (GAPs) of the heterotrimeric G-protein G-alpha-subunits.

This subfamily includes the GEFs (guanine exchange factors) ARHGEF11 (Rho guanine nucleotide exchange factor 11, known as PDZ-RhoGEF) and ARHGEF12 (Rho guanine nucleotide exchange factor 12, also known as leukemia-associated RhoGEF). GEFs activate Rho GTPases by promoting GTP binding. ARHGEF11/12 are regulators of G protein signaling (RGS) domain-containing GEFs; the RGS domain mediates their binding to and activation of Galpha (and Gq also in the case of ARHGEF12), in response to G-protein coupled receptor activation. ARHGEF11 and 12 are involved in serum-signaling, and regulate Yes-Associated Protein (YAP1)-dependent transcription. The ARHGEF12 PDZ domain binds plexin-B1 and the receptor tyrosine kinase insulin-like growth factor receptor (IGF-R1) beta-subunit. ARHGEF12 also interacts with glutamate receptor delta-1(GluD1), a postsynaptic organizer of inhibitory synapses in cortical pyramidal neurons. The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This ARHGEF11-12-like family domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2), arranged in the order: beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F.

1020-1131 2.08e-40

Rho guanine nucleotide exchange factor Pleckstrin homology domain; RhoGEFs belongs to regulator of G-protein signaling (RGS) domain-containing RhoGEFs that are RhoA-selective and directly activated by the Galpha12/13 family of heterotrimeric G proteins. The members here all contain Dbl homology (DH)-PH domains. In addition some members contain N-terminal C1 (Protein kinase C conserved region 1) domains, PDZ (also called DHR/Dlg homologous regions) domains, ANK (ankyrin) domains, and RGS (Regulator of G-protein signalling) domains or C-terminal ATP-synthase B subunit. The DH-PH domains bind and catalyze the exchange of GDP for GTP on RhoA. RhoGEF2/Rho guanine nucleotide exchange factor 2, p114RhoGEF/p114 Rho guanine nucleotide exchange factor, p115RhoGEF, p190RhoGEF, PRG/PDZ Rho guanine nucleotide exchange factor, RhoGEF 11, RhoGEF 12, RhoGEF 18, AKAP13/A-kinase anchoring protein 13, and LARG/Leukemia-associated Rho guanine nucleotide exchange factor are included in this CD. 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.

350-491 2.21e-29

Regulator of G protein signaling (RGS) domain found in the PDZ-Rho guanine nucleotide exchange factor (RhoGEF) protein; The RGS domain is an essential part of the PDZ-RhoGEF (PDZ:Postsynaptic density 95, Disk large, Zona occludens-1; RhoGEF: Rho guanine nucleotide exchange factor; alias PRG) protein, a member of RhoGEFs subfamily of the RGS protein family. The RhoGEFs are peripheral membrane proteins that regulate essential cellular processes, including cell shape, cell migration, and cell cycle progression, as well as gene transcription by linking signals from heterotrimeric G-alpha12/13 protein-coupled receptors to Rho GTPase activation, leading to various cellular responses, such as actin reorganization and gene expression. RhoGEFs subfamily includes leukemia-associated RhoGEF protein (LARG), p115RhoGEF, PDZ-RhoGEF and its rat specific splice variant GTRAP48. The RGS domain of RhoGEFs has very little sequence similarity with the canonical RGS domain of the RGS proteins and is often refered to as RH (RGS Homology) domain. In contrast to p115RhoGEF and LARG, PDZ-RhoGEF cannot serve as a GTPase-activating protein (GAP), due to the mutation of sites in the RGS domain region that are crucial for GAP activity. RGS proteins play critical regulatory role as GTPase activating proteins (GAPs) of the heterotrimeric G-protein G-alpha-subunits. RGS proteins play critical regulatory role as GTPase activating proteins (GAPs) of the heterotrimeric G-protein G-alpha-subunits. RGS proteins regulate many aspects of embryonic development such as glial differentiation, embryonic axis formation, skeletal and muscle development, cell migration during early embryogenesis, as well as apoptosis, cell proliferation, and modulation of cardiac development.

71-144 1.60e-18

PDZ domains of the Na+/H+ exchange regulatory cofactor (NHERF) family (NHERF1-4), and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of the Na+/H+ exchange regulatory cofactor (NHERF) family of multi-PDZ-domain-containing scaffolding proteins (NHERF1-4), and related domains. The NHERF family includes NHERF1 (also known as EBP50), NHERF2 (also known as E3KARP; TKA-1; SIP-1), NHERF3 (also known as CAP70; CLAMP; Napi-Cap-1; PDZD1) and NHERF4 (also known as IKEPP; PDZK2; Napi-Cap-2). NHERF1 and NHERF2 have tandem PDZ domains (PDZ1-2); NHERF3 and NHERF4 have four PDZ domains (PDZ1-4). NHERFs are involved in the regulation of multiple receptors or transporters, such as type II sodium-phosphate cotransporter (Npt2a), purinergic P2Y1 receptor P2Y1R, the beta2-adrenergic receptor (beta2-AR), parathyroid hormone receptor type 1 (PTHR), the lysophosphatidic acid receptors (LPARs), sodium-hydrogen exchanger 3 (NHE3), and cystic fibrosis transmembrane conductance regulator (CFTR). NHERF-PDZ1 domain interaction partners include Npt2a, purinergic P2Y1 receptor, beta2-AR, CFTR, PTHR, NH3, G-protein-coupled receptor kinase 6 (GRK6A), platelet-derived growth factor receptor (PDGFR), B1 subunit of the H+ATPase, cholesterol, receptor for activated C-kinase RACK1, aquaporin 9, among others. The NHERF PDZ2 domain interacts with fewer proteins: NHERF1 PDZ2 binds Npt2a, PTHR, beta-catenin, aquaporin 9, and RACK1; NHERF2 PDZ2 binds LPA2, P2Y1R, and NHE3, cGMP-dependent protein kinase type II (cGKII). NHERF4 PDZ1 and PDZ4 bind the epithelial Ca(2+) channels TRPV5 and TRPV6. NHERF2/NHERF3 heterodimerization is mediated by PDZ domains of NHERF2 and the C-terminal PDZ domain recognition motif of NHERF3. NHERF4 regulates several transporters mediating influx of xenobiotics and nutrients in the small intestine. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This NHERF-like family domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2), arranged in the order: beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F.

PDZ domain 2 of delphilin (L-delphilin isoform), and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 2 of delphilin (also known as glutamate receptor, ionotropic, delta 2-interacting protein 1, L-delphilin). Delphilin, a postsynaptic protein which it is selectively expressed at cerebellar Purkinje cells, links the glutamate receptor delta 2 subunit (GluRdelta2) with the actin cytoskeleton and various signaling molecules. Two alternatively spliced isoforms of delphilin have been characterized: L-delphilin has two PDZ domains, PDZ1 and PDZ2, and S-delphilin has a single PDZ domain (PDZ2). These two isoforms are differently palmitoylated and may be involved in controlling GluRdelta2 signaling in Purkinje cells. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs).

PDZ domain of SH3 and multiple ankyrin repeat domains protein 1 (SHANK1), SHANK2, SHANK3, and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of SHANK1, SHANK2, SHANK3, and related domains. SHANK family proteins, SHANK1 (also known as somatostatin receptor-interacting protein, SSTR-interacting protein, SSTRIP), SHANK2 (also known as cortactin-binding protein 1, proline-rich synapse-associated protein 1), and SHANK3 (proline-rich synapse-associated protein 2) are synaptic scaffolding proteins which are highly enriched in the post-synaptic densities of excitatory synapses. They have been implicated in synaptic transmission, synapse formation, synaptic plasticity, and cytoskeletal remodeling, and are regulators of Cav1 calcium current and CREB target expression. Many protein ligands have been identified for the Shank PDZ domain, such as GKAP (also known as SAPAP), betaPIX (a guanine nucleotide exchange factor used by Rho GTPase family members Rac1 and Cdc42), alpha-latrotoxin, neuroligin, group I metabotropic glutamate receptors (mGluRs), and L-type calcium channels. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands.

PDZ domain of sorting nexin-27 (SNX27), and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of SNX27, and related domains. SNX27 is involved in retrograde transport from endosome to plasma membrane. The PDZ domain of SNX27 links cargo identification to retromer-mediated transport. SNX27 binds to the retromer complex (vacuolar protein sorting 26(VPS26)-VPS29-VPS35), via its PDZ domain binding to VPS26. The SNX27 PDZ domain also binds to cargo including the G-protein-coupled receptors (GPCRs): beta2-adrenergic receptor (beta2AR), beta1AR, parathyroid hormone receptor (PTHR), alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors (AMPARs), NMDA receptors, 5-hydroxytryptamine 4a receptors, frizzled receptors, and somatostatin receptor subtype 5 (SSTR5). Additional binding partners of the SNX27 PDZ domain include G protein-gated inwardly rectifying potassium (Kir3) channels, angiotensin-converting enzyme 2 (ACE2), and PTEN (phosphatase and tensin homolog deleted on chromosome 10); PTEN binding to SNX27 prevents SNX27's association with the retromer complex. SNX27 has been reported to be a host factor needed for efficient entry of an engineered SARS-CoV-2 variant, the spike protein of which contains a deletion at the S1/S2 subunit cleavage site; the PDZ domain of SNX27 binds angiotensin-converting enzyme 2 (ACE2), and may be involved in recycling ACE2 to the plasma membrane, thereby promoting viral entry. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands.

1017-1146 1.23e-12

Rho guanine nucleotide exchange factor 18 Pleckstrin homology (PH) domain; ARHGEF18, also called p114RhoGEF, is a key regulator of RhoA-Rock2 signaling that is crucial for maintenance of polarity in the vertebrate retinal epithelium, and consequently is essential for cellular differentiation, morphology and eventually organ function. ARHGEF18 contains Dbl-homology (DH) and pleckstrin-homology (PH) domains which bind and catalyze the exchange of GDP for GTP on RhoA. 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.

RGS3 down-regulates GPCR signal transduction by increasing the GTPase activity of G-protein alpha subunits, thereby driving G-proteins into their inactive GDP-bound form. It downregulates G-protein-mediated release of inositol phosphates and activation of MAP kinases. In Eph/ephrin signaling, RGS3 binds via its PDZ domain to the cytoplasmic C terminus of Eph receptor tyrosine kinase EphB. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands.

circularly permuted PDZ domain of C-terminal processing peptidase (CPP), a serine protease, and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of CPP (also known as tail-specific protease, PRC protein, Protease Re, and Photosystem II D1 protein processing peptidase), and related domains. CPP belongs to the peptidase S41A family. It cleaves a C-terminal 11 residue peptide from the precursor form of penicillin-binding protein 3, and may have a role in protecting bacterium from thermal and osmotic stresses. In the plant chloroplast, the enzyme removes the C-terminal extension of the D1 polypeptide of photosystem II. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains and as well as those with circular permutations and domain swapping of beta-strands. The canonical PDZ domain contains six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2); arranged as A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F. This CPP-like PDZ domain is a circularly permuted PDZ domain which places beta-strand A on the C-terminus. Another permutation exists in the PDZ superfamily which places both beta-strands A and B on the C-terminus.

They belong to the LAP family, which describes proteins that contain either one or four PDZ domains and 16 LRRs (leucine-rich repeats) and function in controlling cell shape, size and subcellular protein localization. In Drosophila, the Scribble complex, comprising Scribble, discs large, and lethal giant larvae, plays a role in apico-basal cell polarity, in other forms of polarity, including regulation of the actin cytoskeleton, cell signaling and vesicular trafficking, and in tumor development. Mammalian Scribble is important in many aspects of cancer development. Scribble and its homologs can be downregulated or overexpressed in cancer; they have a role in cancer beyond their function in loss of cell polarity. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs).

PDZ domain of syntrophins, and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of syntrophins (including alpha-1-syntrophin, beta-1-syntrophin, beta-2-syntrophin, gamma-1-syntrophin, and gamma-2-syntrophin), and related domains. Syntrophins play a role in recruiting various signaling molecules into signaling complexes and help provide appropriate spatiotemporal regulation of signaling pathways. They function in cytoskeletal organization and maintenance; as components of the dystrophin-glycoprotein complex (DGC), they help maintain structural integrity of skeletal muscle fibers. They link voltage-gated sodium channels to the actin cytoskeleton and the extracellular matrix, and control the localization and activity of the actin reorganizing proteins such as PI3K, PI(3,4)P2 and TAPP1. Through association with various cytoskeletal proteins within the cells, they are involved in processes such as regulation of focal adhesions, myogenesis, calcium homeostasis, and cell migration. They also have roles in synapse formation and in the organization of utrophin, acetylcholine receptor, and acetylcholinesterase at the neuromuscular synapse. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands.

PDZ domain of tamalin, cytohesin-1-interacting protein (CYTIP), and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of tamalin, cytohesin-1-interacting protein, and related domains. Tamalin (trafficking regulator and scaffold protein tamalin, also known as general receptor for phosphoinositides 1-associated scaffold protein, GRASP) functions to link receptors, including group 1 metabotropic glutamate receptors (mGluRs), to neuronal proteins. The tamalin PDZ domain binds the C-terminal domains of group I mGluRs; it also binds potassium/sodium hyperpolarization-activated cyclic nucleotide-gated channel 2 (HCN2), neurotrophin-3 (NT3) TrkCT1-truncated receptor, SAP90/PSD-95-associated protein, and tamalin itself. CYTIP (cytohesin-1-interacting protein, also known as Pleckstrin homology Sec7 and coiled-coil domain-binding protein) sequesters cytohesin-1 in the cytoplasm, limiting its interaction with beta2 integrins; cytohesin-1 binds the CYTIP coiled coil domain. The CYTIP PDZ domain can bind the C-terminal peptide of protocadherin alpha-1 (PCDHA1), indicating a possible interaction between the two. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands.

These MAST proteins contain a DUF1908 domain, a serine/threonine kinase domain, a AGC-kinase C-terminal domain, and a PDZ domain; MAST family member MASTL is a shorter protein lacking the PDZ domain. The PDZ domain gives the MAST family the capacity to scaffold its own kinase activity. These kinases are implicated in the inhibition of neurite outgrowth and regeneration in cultured cells. Their binding partners include microtubules, beta2-syntrophin, TNF receptor-associated factor 6 (TRAF6), cAMP-regulated phosphoprotein (ARPP-16), and PTEN. This family also includes Caenorhabditis elegans KIN-4 MAST kinase, a key longevity factor acting through binding PTEN phosphatase, and Drosophila Drop out which regulates dynein-dependent transport during embryonic development. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs).

1020-1127 8.52e-09

Rho guanine nucleotide exchange factor Pleckstrin homology domain; p190RhoGEF (also called RIP2 or ARHGEF28) belongs to regulator of G-protein signaling (RGS) domain-containing RhoGEFs that are RhoA-selective and directly activated by the Galpha12/13 family of heterotrimeric G proteins. In addition to the Dbl homology (DH)-PH domain, p190RhoGEF contains an N-terminal C1 (Protein kinase C conserved region 1) domain. The DH-PH domains bind and catalyze the exchange of GDP for GTP on RhoA. 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.

SYNJ2BP (also known as mitochondrial outer membrane protein 25, OMP25) regulates endocytosis of activin type 2 receptor kinases through the Ral/RALBP1-dependent pathway and may be involved in suppression of activin-induced signal transduction. Binding partners of the SYNJ2BP PDZ domain include activin type II receptors (ActR-II), and SYNJ2. SYNJ2BP interacts with the PDZ binding motif of the Notch Delta-like ligand 1 (DLL1) and DLL4, promoting Delta-Notch signaling, and inhibiting sprouting angiogenesis. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands.

PDZ domain 2 of partitioning defective 3 (Par3), and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 2 of Par3 (or PAR3 or Par-3, also known as Atypical PKC isotype-specific-interacting protein, ASIP, Drosophila Bazooka) and related domains. Par3 is a scaffold protein involved in organizing cell polarity across animals. Par3 binds numerous molecules both for its recruitment to one pole of the cell and for downstream contributions to polarized cell function. It regulates cell polarity by targeting the Par complex proteins Par6 and atypical protein kinase C (aPKC) to specific cortical sites. Physical interactions between Par3 and the Par complex include Par3 PDZ domain 1 binding to the Par6 PDZ domain, Par3 PDZ domain 1 and PDZ domain 3 binding the Par6's PDZ-binding motif, and an interaction with an undefined region of aPKC that requires both Par3 PDZ2 and PDZ3. The PDZ domains of Par3 have also been implicated as potential phosphoinositide signaling integrators, since its second PDZ domain binds to phosphoinositides, and the third PDZ interacts with phosphoinositide phosphatase PTEN. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands.

75-137 1.42e-08

PDZ domain of DEP domain-containing mTOR-interacting protein (DEPTOR), and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of DEPTOR, and related domains. DEPTOR (also known as DEP domain-containing protein 6, DEP6) is a regulatory protein of mTOR signaling; it is a negative regulator of both the mTORC1 and mTORC2 signaling pathways. DEPTOR's PDZ domain binds to mTOR's FAT domain to suppress mTOR's kinase activity. The DEPTOR PDZ domain also binds lysine-specific demethylase 4A (KDM4A), leucine-rich repeat containing 4 (LRRC4), p38gamma, and major intrinsically disordered Notch2-binding receptor 1 (MINAR1, also known as Ubtor). DEPTOR also interacts with salt-inducible kinase 3 (SIK3). PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This DEPTOR-like family domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2), arranged in the order: beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F.

MAGI proteins have been implicated in the control of cell migration and invasion through altering the activity of phosphatase and tensin homolog (PTEN) and modulating Akt signaling. Four MAGI proteins have been identified (MAGI1-3 and MAGIX). MAGI1-3 have 6 PDZ domains and bind to the C-terminus of PTEN via their PDZ2 domain. MAGIX has a single PDZ domain that is related to MAGI1-3 PDZ domain 5. Other binding partners for MAGI1 include JAM4, C-terminal tail of high risk HPV-18 E6, megalin, TRAF6, Kir4.1 (basolateral K+ channel subunit), and cadherin 23; for MAGI2, include DASM1, dendrin, axin, beta- and delta-catenin, neuroligin, hyperpolarization-activated cation channels, beta1-adrenergic receptors, NMDA receptor, and TARPs; and for MAGI3 includes LPA2. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This MAGI family PDZ4 domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2); arranged as beta-strands A, -B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F.

PDZ domain 2 of Drosophila Scribble, human Scribble homolog, and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 2 of Drosophila Scribble (also known as LAP4), human Scribble homolog (also known as hScrib, LAP4, CriB1, ScrB1 and Vartul), and related domains. They belong to the LAP family, which describes proteins that contain either one or four PDZ domains and 16 LRRs (leucine-rich repeats) and function in controlling cell shape, size and subcellular protein localization. In Drosophila, the Scribble complex, comprising Scribble, discs large, and lethal giant larvae, plays a role in apico-basal cell polarity, in other forms of polarity, including regulation of the actin cytoskeleton, cell signaling and vesicular trafficking, and in tumor development. Mammalian Scribble is important in many aspects of cancer development. Scribble and its homologs can be downregulated or overexpressed in cancer; they have a role in cancer beyond their function in loss of cell polarity. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands.

PDZ domain 1 of harmonin isoforms a, b, and c, and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 1 of harmonin isoforms a, b, and c, and related domains. Harmonin (also known as Usher Type 1C, PDZ-73 and AIE-75) is a key organizer of the Usher (USH) protein interactome. USH syndrome is the leading cause of hereditary sensory deaf-blindness in humans; three clinically distinct types of USH have been identified, type 1 to 3. The gene encoding harmonin (USH1C) is the causative gene for the USH type 1C phenotype. There are at least 10 alternatively spliced isoforms of harmonin, which are divided into three subclasses (a, b, and c). All isoforms contain the first two PDZ domains and the first coiled-coil domain. The a and b isoforms all have a third PDZ domain. The different PDZ domains are responsible for interactions with all known Usher syndrome type 1 proteins, and most Usher syndrome type 2 proteins. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This harmonin family PDZ1 domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2), arranged in the order: beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F.

MUPP1 and PATJ serve as scaffolding proteins linking different proteins and protein complexes involved in the organization of tight junctions and epithelial polarity. MUPP1 contains an L27 (Lin-2 and Lin-7 binding) domain and 13 PDZ domains. PATJ (also known as INAD-like) contains an L27 domain and ten PDZ domains. MUPP1 and PATJ share several binding partners, including junctional adhesion molecules (JAM), zonula occludens (ZO)-3, Pals1 (protein associated with Lin-7), Par (partitioning defective)-6 proteins, and nectins (adherence junction adhesion molecules). PATJ lacks 3 PDZ domains seen in MUPP1: PDZ6, 9, and 13; consequently, MUPP1 PDZ7 and 8 align with PATJ PDZ6 and 7; and MUPP1 PDZ domains 10-12 align with PATJ PDZ domains 8-10. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands.

PDZ domain 3 of human discs large homolog 1 (Dlg1), Dlg2, and Dlg4, Drosophila disc large (Dlg), and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 3 of Drosophila Dlg1, human Dlg1, 2, and 4 and related domains. Dlg1 (also known as synapse-associated protein Dlg197; SAP-97), Dlg2 (also known as channel-associated protein of synapse-110; postsynaptic density protein 93, PSD-93), Dlg4 (also known as postsynaptic density protein 95, PSD-95; synapse-associated protein 90, SAP-90) each have 3 PDZ domains and belong to the membrane-associated guanylate kinase family. Dlg1 regulates antigen receptor signaling and cell polarity in lymphocytes, B-cell proliferation and antibody production, and TGFalpha bioavailability; its PDZ3 domain binds pro-TGFalpha, and its PDZ2 domain binds the TACE metalloprotease responsible for cleaving pro-TGFalpha to a soluble form. Dlg2 is involved in N-methyl-D-aspartate (NMDA) receptor signaling, regulating surface expression of NMDA receptors in dorsal horn neurons of the spinal cord; it interacts with NMDA receptor subunits and with Shaker-type K+ channel subunits to cluster into a channel complex. The Dlg4 PDZ1 domain binds NMDA receptors, and its PDZ2 domain binds neuronal nitric oxide synthase (nNOS), forming a complex in neurons. The Drosophila Scribble complex (Scribble, Dlg, and lethal giant larvae) plays a role in apico-basal cell polarity, and in other forms of polarity, including regulation of the actin cytoskeleton, cell signaling and vesicular trafficking, and in tumor development; postsynaptic targeting of Drosophila DLG requires interactions mediated by the first two PDZ domains. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands.

92-145 1.86e-07

permuted PDZ domain of Deg/high-temperature requirement factor A (HtrA) family of housekeeping serine proteases and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of Deg/HtrA-type serine proteases that participate in folding and degradation of aberrant proteins, and in processing and maturation of native proteins. Typically, these proteases have an N-terminal serine protease domain and at least one C-terminal PDZ domain that recognizes substrates, and in some cases activates the protease function. An exception is yeast Nma11p which has two protease domains and four PDZ domains; its N-terminal half is comprised of a protease domain, followed by two PDZ domains, and its C-terminal half has a similar domain arrangement. HtrA-type proteases include the human HtrA1-4 and MBTPS2, tricorn protease, DegS, DegP and C-terminal processing peptidase, cyanobacterial serine proteases Hhoa, HhoB, and HtrA, and yeast Nma11p. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-termini of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains and as well as those with circular permutations and domain swapping of beta-strands. The canonical PDZ domain contains six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2); arranged as A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F. This Deg/HtrA family PDZ domain is a circularly permuted PDZ domain which places beta-strand A at the C-terminus. Another permutation exists in the PDZ superfamily which places both beta-strands A and B on the C-terminus.

PDZ domain 2 of harmonin isoforms a, b, and c, and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 2 of harmonin isoforms a, b, and c, and related domains. Harmonin (also known as Usher Type 1C, PDZ-73 and AIE-75) is a key organizer of the Usher (USH) protein interactome. USH syndrome is the leading cause of hereditary sensory deaf-blindness in humans; three clinically distinct types of USH have been identified, type 1 to 3. The gene encoding harmonin (USH1C) is the causative gene for the USH type 1C phenotype. There are at least 10 alternatively spliced isoforms of harmonin, which are divided into three subclasses (a, b, and c). All isoforms contain the first two PDZ domains and the first coiled-coil domain. The a and b isoforms all have a third PDZ domain. The different PDZ domains are responsible for interactions with all known Usher syndrome type 1 proteins, and most Usher syndrome type 2 proteins. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This harmonin family PDZ2 domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2), arranged in the order: beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F.

PDZ domain 3 of multi-PDZ-domain protein 1 (MUPP1) and PATJ (protein-associated tight junction) and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 3 of MUPP1 and PATJ, and related domains. MUPP1 and PATJ serve as scaffolding proteins linking different proteins and protein complexes involved in the organization of tight junctions and epithelial polarity. MUPP1 contains an L27 (Lin-2 and Lin-7 binding) domain and 13 PDZ domains. PATJ (also known as INAD-like) contains an L27 domain and ten PDZ domains. MUPP1 and PATJ share several binding partners, including junctional adhesion molecules (JAM), zonula occludens (ZO)-3, Pals1 (protein associated with Lin-7), Par (partitioning defective)-6 proteins, and nectins (adherence junction adhesion molecules). PATJ lacks 3 PDZ domains seen in MUPP1: PDZ6, 9, and 13; consequently, MUPP1 PDZ7 and 8 align with PATJ PDZ6 and 7; and MUPP1 PDZ domains 10-12 align with PATJ PDZ domains 8-10.

PDZ domain of protein Lin-7 and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of Lin-7 (also known as LIN-7 or LIN7), and related domains. Lin-7 targets and organize protein complexes to epithelial and synaptic plasma membranes. There are three mammalian Lin-7 homologs: Lin-7A (protein lin-7 homolog A, also known as mammalian lin-seven protein 1 (MALS-1), vertebrate lin-7 homolog 1 (Veli-1), tax interaction protein 33); Lin-7B (also known as MALS-2, Veli-2); and Lin-7C (also known as MALS-3, Veli-3). Lin-7 is involved in localization of the Let-23 growth factor receptor to the basolateral membrane of epithelial cells, in tight junction localization of insulin receptor substrate p53 (IRSp53), in retaining gamma-aminobutyric (GABA) transporter (BGT-1) at the basolateral surface of epithelial cells, and in regulating recruitment of neurotransmitter receptors to the postsynaptic density (PSD). The Lin7 PDZ domain binds Let-23, BGT and beta-catenin, and NMDA (N-methyl-D-aspartate) receptor NR2B. Lin-7 also binds to the PDZ binding motif located in the C-terminal tail of Rhotekin, an effector protein for small GTPase Rho. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands.

82-144 9.89e-07

circularly permuted first PDZ domain (PDZ1) of Escherichia coli periplasmic serine endoprotease DegP and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 1 of Escherichia coli DegP (also known as heat shock protein DegP and Protease Do) and related domains. DegP belongs to the HtrA family of housekeeping proteases. It acts as a protease, degrading transiently denatured and unfolded or misfolded proteins which accumulate in the periplasm following heat shock or other stress conditions, and as a molecular chaperone at low temperatures. DegP has two PDZ domains in addition to the protease domain; its PDZ1 domain is responsible for identifying the distinct substrate sequences that affect degradation (degron) of the substrate sequence, and its PDZ2 domain is responsible for combining with other DegP monomers to form a stable oligomer structure. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains and as well as those with circular permutations and domain swapping of beta-strands. The canonical PDZ domain contains six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2); arranged as A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F. This DegP family PDZ domain 1 is a circularly permuted PDZ domain which places beta-strand A on the C-terminus. Another permutation exists in the PDZ superfamily which places both beta-strands A and B on the C-terminus.

PDZ domain 7 of PDZ domain containing 2 (PDZD2), PDZ domain 4 of human pro-interleukin-16 (isoform 1, 1332 AA), and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 7 of PDZD2, also known as KIAA0300, PIN-1, PAPIN, activated in prostate cancer (AIPC) and PDZ domain-containing protein 3 (PDZK3). PDZD2 has seven PDZ domains. PDZD2 is expressed at exceptionally high levels in the pancreas and certain cancer tissues, such as prostate cancer. It promotes the proliferation of insulinoma cells and is upregulated during prostate tumorigenesis. In osteosarcoma (OS), the microRNA miR-363 acts as a tumor suppressor by inhibiting PDZD2. This family include the PDZ domain of the secreted mature form of human interleukin-16 (IL-16); this is the fourth PDZ domain (PDZ4) of human pro-interleukin-16 (isoform 1, also known as nPro-Il-16). Precursor IL-16 is cleaved to produce pro-IL-16 and C-terminal mature IL-16. Pro-IL-16 functions as a regulator of T cell growth; mature IL-16 is a CD4 ligand that induces chemotaxis and CD25 expression in CD4+ T cells. IL-16 bioactivity has been closely associated with the progression of several different cancers PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs).

PDZ domain of densin, erbin, and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of densin, erbin, and related domains. Densin (also known as leucine-rich repeat-containing protein 7, LRRC7, densin-180, protein LAP1) and erbin (also known as densin-180-like protein, Erbb2-interacting protein, protein LAP2) belong to the LAP (leucine-rich repeat and PDZ domain) family of scaffolding proteins that play roles in the maintenance of cell shape and apical-basal polarity. Densin and erbin are components of the excitatory postsynaptic compartment and are regulators of dendritic morphology and postsynaptic structure. The densin PDZ domain binds CaV1.3 alpha1 subunit, delta-catenin, and MAGUIN-1. Binding partners of the erbin PDZ domain include ErbB receptor tyrosine kinase ErbB2, HTLV-1 Tax1, Cav1.3 Ca2+channels, and constituents of the cadherin:catenin cell adhesion complex, in particular delta-catenin, p0071 and ARVCF. The erbin PDZ domain binds Smad3, a transductor of the TGFbeta pathway, possibly by a novel interface of binding. Erbin and two other LAP proteins (scribble and lano) redundantly regulate epithelial polarity and apical adhesion complex. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This densin and erbin-like family domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2), arranged as beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F.

PDZ domain 4 of Drosophila Scribble, human Scribble homolog, and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 4 of Drosophila Scribble (also known as LAP4), human Scribble homolog (also known as hScrib, LAP4, CriB1, ScrB1 and Vartul), and related domains. They belong to the LAP family, which describes proteins that contain either one or four PDZ domains and 16 LRRs (leucine-rich repeats) and function in controlling cell shape, size and subcellular protein localization. In Drosophila, the Scribble complex, comprising Scribble, discs large, and lethal giant larvae, plays a role in apico-basal cell polarity, in other forms of polarity, including regulation of the actin cytoskeleton, cell signaling and vesicular trafficking, and in tumor development. Mammalian Scribble is important in many aspects of cancer development. Scribble and its homologs can be downregulated or overexpressed in cancer; they have a role in cancer beyond their function in loss of cell polarity. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands.

PDZ domain 1 of Zonula Occludens-1 (ZO-1), homologs ZO-2 and ZO-3, and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 1 of ZO-1, -2, -3 and related domains. Zonula occludens proteins (ZO-1, ZO-2, ZO-3) are multi-PDZ domain proteins involved in the maintenance and biogenesis of multi-protein networks at the cytoplasmic surface of intercellular contacts in epithelial and endothelial cells. They have three N-terminal PDZ domains, PDZ1-3, followed by a Src homology-3 (SH3) domain and a guanylate kinase (GuK)-like domain. Among protein-protein interactions for all ZO proteins is the binding of the first PDZ domain (PDZ1) to the C-termini of claudins, and the homo- and hetero-dimerization of ZO-proteins via their second PDZ domain (PDZ2), which takes place by symmetrical domain swapping of the first two beta-strands of PDZ2. At the cell level, ZO-1 and ZO-2 are involved in polarity maintenance, gene transcription, cell proliferation, and tumor cell metastasis. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This ZO family PDZ1 domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2), arranged in the order: beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F.

MUPP1 and PATJ serve as scaffolding proteins linking different proteins and protein complexes involved in the organization of tight junctions and epithelial polarity. MUPP1 contains an L27 (Lin-2 and Lin-7 binding) domain and 13 PDZ domains. PATJ (also known as INAD-like) contains an L27 domain and ten PDZ domains. MUPP1 and PATJ share several binding partners, including junctional adhesion molecules (JAM), zonula occludens (ZO)-3, Pals1 (protein associated with Lin-7), Par (partitioning defective)-6 proteins, and nectins (adherence junction adhesion molecules). PATJ lacks 3 PDZ domains seen in MUPP1: PDZ6, 9, and 13; consequently, MUPP1 PDZ7 and 8 align with PATJ PDZ6 and 7; and MUPP1 PDZ domains 10-12 align with PATJ PDZ domains 8-10. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs).

PDZ domain 2 of human discs large homolog 1 (Dlg1), Dlg2, and Dlg4, Drosophila disc large (Dlg), and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 1 of Drosophila Dlg1, human Dlg1,2, and 4 and related domains. Dlg1 (also known as synapse-associated protein Dlg197 or SAP-97), Dlg2 (also known as channel-associated protein of synapse-110, postsynaptic density protein 93, or PSD-93), Dlg4 (also known as postsynaptic density protein 95, PSD-95, synapse-associated protein 90, or SAP-90) each have 3 PDZ domains and belong to the membrane-associated guanylate kinase family. Dlg1 regulates antigen receptor signaling and cell polarity in lymphocytes, B-cell proliferation and antibody production, and TGFalpha bioavailability; its PDZ3 domain binds pro-TGFalpha, and its PDZ2 domain binds the TACE metalloprotease responsible for cleaving pro-TGFalpha to a soluble form. Dlg2 is involved in N-methyl-D-aspartate (NMDA) receptor signaling. It regulates surface expression of NMDA receptors in dorsal horn neurons of the spinal cord, and it also interacts with NMDA receptor subunits and with Shaker-type K+ channel subunits to cluster into a channel complex. Dlg4 PDZ1 domain binds NMDA receptors, and its PDZ2 domain binds neuronal nitric oxide synthase (nNOS), forming a complex in neurons. The Drosophila Scribble complex (Scribble, Dlg, and lethal giant larvae) plays a role in apico-basal cell polarity, and in other forms of polarity, including regulation of the actin cytoskeleton, cell signaling and vesicular trafficking, and in tumor development. Postsynaptic targeting of Drosophila DLG requires interactions mediated by the first two PDZ domains. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This Dlg-like family PDZ2 domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2), arranged in the order: beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F.

1017-1127 4.97e-06

Rho guanine nucleotide exchange factor 2 Pleckstrin homology (PH) domain; ARHGEF2, also called GEF-H1, acts as guanine nucleotide exchange factor (GEF) for RhoA GTPases. It is thought to play a role in actin cytoskeleton reorganization in different tissues since its activation induces formation of actin stress fibers. ARHGEF2 contains a C1 domain followed by Dbl-homology (DH) and pleckstrin-homology (PH) domains which bind and catalyze the exchange of GDP for GTP on RhoA. 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.

PTPN13 regulates negative apoptotic signaling and mediates phosphoinositide 3-kinase (PI3K) signaling. PTPN13 has five PDZ domains. Proteins known to interact with PTPN13 PDZ domains include: PLEKHA1 and PLEKHA2 via PTPN13-PDZ domain 1, Fas receptor and thyroid receptor-interacting protein 6 via PTPN13-PDZ domain 2, nerve growth factor receptor and protein kinase N2 via PTPN13-PDZ domain 3, PDZ and LIM domain 4 (PDLIM4) via PTPN13-PDZ domains 2 and 4, and brain calpain-2 via PTPN13-PDZ domains 3, 4 and 5. Calpain-2-mediated PTPN13 fragments may be involved in abnormal tau aggregation and increased risk for Alzheimer's disease. FRMPD2 is localized in the basolateral membranes of polarized epithelial cells and is associated with tight junction formation and immune response; it contains 3 PDZ domains. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs).

PDZ domain of neuronal nitric oxide synthase (nNOS), and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 1 of nNOS, and related domains. nNOS produces a key signaling molecule, nitric oxide (NO), which has diverse functions throughout the body and acts as a neurotransmitter and intracellular signaling molecule in the central and peripheral nervous system. nNOS is concentrated at synaptic junctions in the brain and motor endplates in skeletal muscle. The PDZ domain of neuronal nitric oxide synthase (nNOS) interacts with the PDZ domain of alpha1-syntrophin (in muscle cells) and with the second PDZ domain of Disks large homolog 4 (Dlg4, also known as PSD-95), and nitric oxide synthase 1 adaptor protein NOS1AP in neurons. Dlg4 binds NMDA receptors, and nNOS, forming a complex in neurons. NOS1AP competes with Dgl4 for the nNOS PDZ domain and prevents the coupling of nNos activation with NMDA receptor-mediated calcium influx. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs).

PDZ domain of GIPC family proteins; GIPC1/GIPC (GAIP/RGS19-interacting protein), GIPC2, and GIPC3 (also known as C19orf64) constitute the GIPC family. These proteins contain an N-terminal GIPC-homology 1 (GH1) domain, a central PDZ domain, and a C-terminal GH2 domain. GIPC proteins function as adaptor molecules that assemble RTKs, GPCRs, integrins, transmembrane proteins and cytoplasmic signaling regulators as cargoes of MYO6-dependent endocytic transport. Mutations in the Gipc1 and Gipc2 genes have been linked to cancer, while mutations in the Gipc3 gene cause nonsyndromic hearing loss. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs).

PDZ domain of tax1-binding protein 3 (TAX1BP3), and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of TAX1BP3, and related domains. TAX1BP3 (also known as glutaminase-interacting protein 3, tax interaction protein 1, TIP-1, tax-interacting protein 1) may regulate a number of protein-protein interactions by competing for PDZ domain binding sites. TAX1BP3 binds beta-catenin and may act as an inhibitor of the Wnt signaling pathway. It competes with LIN7A (also known as Lin-7A or LIN-7A) for inward rectifier potassium channel 4 (KCNJ4) binding, and thereby promotes KCNJ4 internalization. It may play a role in the Rho signaling pathway, and in the activation of CDC42 by the viral protein HPV16 E6. Binding partners of the TAX1BP3 PDZ domain include beta-catenin, KCNJ4, glutaminase liver isoform (GLS2), rho guanine nucleotide exchange factor 16 (ARHGEF16), rhotekin, and CDK5 regulatory subunit-associated protein 3 (also known as LAPZ).

PDZ domain 3 of Zonula Occludens-1 (ZO-1), homologs ZO-2 and ZO-3, and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 3 of ZO-1, -2, -3 and related domains. Zonula occludens proteins (ZO-1, ZO-2, ZO-3) are multi-PDZ domain proteins involved in the maintenance and biogenesis of multi-protein networks at the cytoplasmic surface of intercellular contacts in epithelial and endothelial cells. They have three N-terminal PDZ domains, PDZ1-3, followed by a Src homology-3 (SH3) domain and a guanylate kinase (GuK)-like domain. Among protein-protein interactions for all ZO proteins is the binding of the first PDZ domain (PDZ1) to the C-termini of claudins , and the homo- and hetero-dimerization of ZO-proteins via their second PDZ domain (PDZ2), which takes place by symmetrical domain swapping of the first two beta-strands of PDZ2. At the cell level, ZO-1 and ZO-2 are involved in polarity maintenance, gene transcription, cell proliferation, and tumor cell metastasis. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This ZO family PDZ3 domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2), arranged in the order: beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F.

PDZ domain 2 of the full-length isoform of whirlin and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 2 of the full-length isoform of whirlin and related domains. Whirlin is an essential protein for developmental pathways in photoreceptor cells of the retina and hair cells of the inner ear. The full-length whirlin isoform has two harmonin N-like domains, three PDZ domains, a proline-rich region, and a PDZ-binding motif. Whirlin isoforms may form different complexes at the periciliary membrane complex (PMC) in photoreceptors, and the stereociliary tip and base in inner ear hair cells. It interacts with ADGRV1 and usherin at the PMC; with SANS and RpgrORF15 at the connecting cilium in photoreceptors; with EPS8, MYO15A, p55, and CASK proteins at the stereociliary tip of inner ear hair cells; and with ADGRV1, usherin, and PDZD7 at the stereociliary base in inner ear hair cells. Mutations in the gene encoding whirlin (WHRN; also known as USH2D and DFNB31), have been found to cause either USH2 subtype (USH2D) or autosomal recessive non-syndromic deafness type 31 (DFNB31). Whirlin is the key protein in the USH2 complex (whirlin, usherin and GPR98) which recruits other USH2 causative proteins at the periciliary membrane in photoreceptors and the ankle link of the stereocilia in hair cells. Whirlin's interaction with espin, another stereociliary protein, may be important for the architecture of the USH2 complex. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This whirlin family PDZ2 domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2), arranged in the order: beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F.

PDZ domain 1 of delphilin (L-delphilin isoform), and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 1 of delphilin (also known as glutamate receptor, ionotropic, delta 2-interacting protein 1, L-delphilin). Delphilin, a postsynaptic protein which is selectively expressed at cerebellar Purkinje cells, links the glutamate receptor delta 2 subunit (GluRdelta2) with the actin cytoskeleton and various signaling molecules. Two alternatively spliced isoforms of delphilin have been characterized: L-delphilin has two PDZ domains, PDZ1 and PDZ2, and S-delphilin has a single PDZ domain (PDZ2). These two isoforms are differently palmitoylated and may be involved in controlling GluRdelta2 signaling in Purkinje cells. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This delphilin-like family PDZ1 domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2), arranged in the order: beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F.

379-487 1.53e-05

Regulator of G protein signaling (RGS) domain superfamily; The RGS domain is an essential part of the Regulator of G-protein Signaling (RGS) protein family, a diverse group of multifunctional proteins that regulate cellular signaling events downstream of G-protein coupled receptors (GPCRs). RGS proteins play critical regulatory roles as GTPase activating proteins (GAPs) of the heterotrimeric G-protein G-alpha-subunits. While inactive, G-alpha-subunits bind GDP, which is released and replaced by GTP upon agonist activation. GTP binding leads to dissociation of the alpha-subunit and the beta-gamma-dimer, allowing them to interact with effectors molecules and propagate signaling cascades associated with cellular growth, survival, migration, and invasion. Deactivation of the G-protein signaling controlled by the RGS domain accelerates GTPase activity of the alpha subunit by hydrolysis of GTP to GDP, which results in the reassociation of the alpha-subunit with the beta-gamma-dimer and thereby inhibition of downstream activity. As a major G-protein regulator, RGS domain containing proteins are involved in many crucial cellular processes such as regulation of intracellular trafficking, glial differentiation, embryonic axis formation, skeletal and muscle development, and cell migration during early embryogenesis. RGS proteins are also involved in apoptosis and cell proliferation, as well as modulation of cardiac development. Several RGS proteins can fine-tune immune responses, while others play important roles in neuronal signals modulation. Some RGS proteins are principal elements needed for proper vision.

PDZ domain 1 of inactivation-no-after-potential D (INAD), and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 1 of INAD, and related domains. INAD assembles key enzymes of the Drosophila compound eye photo-transduction pathway into a supramolecular complex, supporting efficient and fast light signaling. It contains 5 PDZ domains arranged in tandem (PDZ1-PDZ5) which independently bind various proteins. INAD PDZ2 binds eye-specific protein kinase C, INAD PDZ3 binds transient receptor potential (TRP) channel, and INAD PDZ4,5 tandem binds NORPA (phospholipase Cbeta, PLCbeta). Mutations of the inaD gene that lead to disruption of each of these interactions impair fly photo signal transduction. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This INAD-like family PDZ1 domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2), arranged in the order: beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F.

circularly permuted PDZ domain 2 (PDZ-C) of Escherichia coli Regulator of sigma-E protease (RseP) and related domains; Permuted PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of ResP (also known as Site-2 protease RseP, and YaeL) and related domains. RseP is involved in the regulation of an extracytoplasmic stress response through the cleavage of membrane-spanning anti-stress-response transcription factor (anti-sigmaE) protein RseA; it cleaves the peptide bond between the critical alanine and cysteine in the transmembrane region of RseA, releasing the cytoplasmic domain of RseA with it associated sigmaE. RseP contains two tandem-arranged periplasmic PDZ domains (PDZ-N/PDZ1 and PDZ-C/PDZ2) which act to negatively regulate protease action on intact RseA; they serve as a size-exclusion filter which prevents the access of an intact RseA into the active site of RseP. PDZ domains usually bind in sequence-specific manner to short peptide sequences located at the C-terminal of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains and as well as those with circular permutations and domain swapping of beta-strands. The canonical PDZ domain contains six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2); arranged as beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F. This RseP family PDZ domain is a circularly permuted PDZ domain which places both beta-strands A and B at the C-terminus. Another permutation exists in the PDZ superfamily which places beta-strand A at the C-terminus.

PDZ domain of microtubule-associated serine-threonine (MAST) protein kinase 3 (MAST3); PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of MAST3, and related domains. MAST3 belongs to the MAST family kinases, which include MAST1-4. These MAST proteins contain a DUF1908 domain, a serine/threonine kinase domain, a AGC-kinase C-terminal domain, and a PDZ domain. MAST3 plays a critical role in regulating the immune response of inflammatory bowel disease (IBD), and is involved in the process of cytoskeleton organization, intracellular signal transduction and peptidyl-serine phosphorylation. MAST3 also promotes the proliferation and inflammation of fibroblast-like synoviocytes in rheumatoid arthritis. Binding partners of MAST3 include cAMP-regulated phosphoprotein (ARPP-16) and the tumor suppressor PTEN. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs).

PDZ domain 2 of the canonical isoform 1 of PDZ domain containing 7 (PDZD7), and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 2 of the long isoform 1 of PDZD7, and related domains. PDZD7 is critical for the organization of Usher syndrome type 2 (USH2) complex. Usher syndrome is the leading cause of hereditary sensory deaf-blindness in humans; USH2 is the most common sub-type. Formation of the USH2 complex is based upon heterodimerization between PDZD7 and whirlin (another PDZ domain-containing protein) and a subsequent dynamic interplay between USH2 proteins via their multiple PDZ domains. The PDZD7 PDZ2 domain binds GPR98 (also known as VLGR1) and usherin (USH2A). PDZD7 and whirlin form heterodimers through their multiple PDZ domains; whirlin and PDZD7 interact with usherin and GPR98 to form an interdependent ankle link complex. PDZD7 also interacts with myosin VIIa. PDZD7 also forms homodimers through its PDZ2 domain. Various isoforms of PDZD7 produced by alternative splicing have been identified; this subgroup includes the second PDZ domain of the canonical isoform of PDZD7- isoform 1. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This PDZD7-like family PDZ2 domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2), arranged in the order: beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F.

PDZ domain 3 of Discs Large 5 (Dlg5) and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 3 of Drosophila and mammalian Dlg5, and related domains. Dlg5 is a scaffold protein with multiple conserved functions that are independent of each other in regulating growth, cell polarity, and cell adhesion. It has a coiled-coil domain, 4 PDZ domains and a MAGUK domain (an SH3 domain next to a non-catalytically active guanylate kinase domain). Deregulation of Dlg5 has been implicated in the malignancy of several cancer types. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This Dlg5-like family PDZ3 domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2), arranged in the order: beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F.

73-143 7.32e-05

PDZ domain of microtubule-associated serine-threonine (MAST) protein kinase 1; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of MAST family kinase MAST1, and related domains. MAST1 belongs to the MAST family kinases, which include MAST1-4. These MAST proteins contain a DUF1908 domain, a serine/threonine kinase domain, a AGC-kinase C-terminal domain, and a PDZ domain; MAST family member MASTL is a shorter protein lacking the PDZ domain. MAST1 functions as a scaffold protein to link the dystrophin/utrophin network with microfilaments via syntrophin, and it has been identified as a main driver of cisplatin resistance in human cancers. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands.

71-135 9.22e-05

PDZ domain 1 of syntenin-1, syntenin-2, and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 1 of syntenin-1, syntenin-2, and related domains. Syntenins are implicated in various cellular processes such as trafficking, signaling, and cancer metastasis. They bind to signaling and adhesion molecules, such as syndecans, neurexins, ephrin B, and phospholipid PIP2. Through its tandem PDZ domains (PDZ1 and PDZ2), syntenin links syndecans to other cell surface receptors and kinases, such as E-cadherin and ephrin-B, establishing signaling crosstalk. During syndecan binding, syntenin PDZ2 serves as a high-affinity domain, and PDZ1, also necessary for binding, acts as a complementary, low-affinity domain; this is also the case for syntenin binding to proto-oncogene c-Src. The syntenin PDZ domain-PIP2 interaction controls Arf6-mediated syndecan recycling through endosomal compartments; both PDZ1 and PDZ2 interact with PIP2. Different binding partners and downstream regulators of syntenin1 PDZ domains, such as to proto-oncogene c-Src, mitogen-activated protein kinase (MAPK), and focal adhesion kinase (FAK), have been identified that promote the progression and invasion of a variety of cancers, such as melanoma, glioblastoma multiforme and breast cancer. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This syntenin-like family domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2), arranged as beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta- strand F.

1020-1127 1.52e-04

rho guanine nucleotide exchange factor; RhoGEFs belongs to regulator of G-protein signaling (RGS) domain-containing RhoGEFs that are RhoA-selective and directly activated by the Galpha12/13 family of heterotrimeric G proteins. The members here all contain Dbl homology (DH)-PH domains. In addition some members contain N-terminal C1 (Protein kinase C conserved region 1) domains, PDZ (also called DHR/Dlg homologous regions) domains, ANK (ankyrin) domains, and RGS (Regulator of G-protein signalling) domains or C-terminal ATP-synthase B subunit. The DH-PH domains bind and catalyze the exchange of GDP for GTP on RhoA. RhoGEF2/Rho guanine nucleotide exchange factor 2, p114RhoGEF/p114 Rho guanine nucleotide exchange factor, p115RhoGEF, p190RhoGEF, PRG/PDZ Rho guanine nucleotide exchange factor, RhoGEF 11, RhoGEF 12, RhoGEF 18, AKAP13/A-kinase anchoring protein 13, and LARG/Leukemia-associated Rho guanine nucleotide exchange factor are included in this CD. 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.

PDZ domain 1 of the full-length isoform of whirlin and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 1 of the full-length isoform of whirlin and related domains. Whirlin is an essential protein for developmental pathways in photoreceptor cells of the retina and hair cells of the inner ear. The full-length whirlin isoform has two harmonin N-like domains, three PDZ domains, a proline-rich region, and a PDZ-binding motif. Whirlin isoforms may form different complexes at the periciliary membrane complex (PMC) in photoreceptors, and the stereociliary tip and base in inner ear hair cells. It interacts with ADGRV1 and usherin at the PMC; with SANS and RpgrORF15 at the connecting cilium in photoreceptors; with EPS8, MYO15A, p55, and CASK proteins at the stereociliary tip of inner ear hair cells; and with ADGRV1, usherin, and PDZD7 at the stereociliary base in inner ear hair cells. Mutations in the gene encoding whirlin (WHRN; also known as USH2D and DFNB31), have been found to cause either USH2 subtype (USH2D) or autosomal recessive non-syndromic deafness type 31 (DFNB31). Whirlin is the key protein in the USH2 complex (whirlin, usherin and GPR98) which recruits other USH2 causative proteins at the periciliary membrane in photoreceptors and the ankle link of the stereocilia in hair cells. Whirlin's interaction with espin, another stereociliary protein, may be important for the architecture of the USH2 complex. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This whirlin family PDZ1 domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2), arranged in the order: beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F.

circularly permuted PDZ domain of high-temperature requirement factor A (HtrA) family serine proteases and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of HtrA family serine proteases including human HtrA1, HtrA2 (mitochondrial), HtrA3, and HtrA4, and related domains. These proteases are key enzymes associated with pregnancy. Their diverse biological functions include cell growth proliferation, migration and apoptosis. They are also implicated in disorders including Alzheimer's, Parkinson's, arthritis and cancer. HtrA1 (also known as high-temperature requirement A serine peptidase 1, L56, and serine protease 11) substrates include extracellular matrix proteins, proteoglycans, and insulin-like growth factor (IGF)-binding proteins. HtrA1 also inhibits signaling by members of the transforming growth factor beta (TGF-beta) family. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping of beta-strands. The canonical PDZ domain contains six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2); arranged as A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F. This HtrA-like PDZ domain is a circularly permuted PDZ domain which places beta-strand A on the C-terminus. Another permutation exists in the PDZ superfamily which places both beta-strands A and B on the C-terminus.

A-kinase anchoring protein 13 Pleckstrin homology (PH) domain; The Rho-specific GEF activity of AKAP13 (also called Brx-1, AKAP-Lbc, and proto-Lbc) mediates signaling downstream of G-protein coupled receptors and Toll-like receptor 2. It plays a role in cell growth, cell development and actin fiber formation. Protein kinase A (PKA) binds and phosphorylates AKAP13, regulating its Rho-GEF activity. Alternative splicing of this gene in humans has at least 3 transcript variants encoding different isoforms (i.e. proto-/onco-Lymphoid blast crisis, Lbc and breast cancer nuclear receptor-binding auxiliary protein, Brx) containing a dbl oncogene homology (DH) domain and PH domain which are required for full transforming activity. The DH domain is associated with guanine nucleotide exchange activation while the PH domain has multiple functions including determine protein sub-cellular localisation via phosphoinositide interactions, while others bind protein partners. Other ligands include protein kinase C which is bound by the PH domain of AKAP13, serving to activate protein kinase D and mobilize a cardiac hypertrophy signaling pathway. 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.

PDZ domain of Ras-associating and dilute domain-containing protein (Radil) and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 1 of Radil (also known as protein KIAA1849) and related domains. Radil is required for cell adhesion and migration of neural crest precursors during development. Radil is a component of a Rasip1-Radil-ARHGAP29 complex at endothelial cell-cell junctions. Rap1, via its effectors Radil and Rasip1 and their binding partner ArhGAP29, controls the endothelial barrier by decreasing Rho-mediated radial tension on cell-cell junctions. ArhGAP29 binds the Radil PDZ domain. The Radil PDZ domain also binds kinesin family protein 14 (KIF14); KIF14 negatively regulates Rap1-mediated inside-out integrin activation by tethering Radil on microtubules. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands.

MUPP1 and PATJ serve as scaffolding proteins linking different proteins and protein complexes involved in the organization of tight junctions and epithelial polarity. MUPP1 contains an L27 (Lin-2 and Lin-7 binding) domain and 13 PDZ domains. PATJ (also known as INAD-like) contains an L27 domain and ten PDZ domains. MUPP1 and PATJ share several binding partners, including junctional adhesion molecules (JAM), zonula occludens (ZO)-3, Pals1 (protein associated with Lin-7), Par (partitioning defective)-6 proteins, and nectins (adherence junction adhesion molecules). PATJ lacks 3 PDZ domains seen in MUPP1: PDZ6, 9, and 13; consequently, MUPP1 PDZ7 and 8 align with PATJ PDZ6 and 7; and MUPP1 PDZ domains 10-12 align with PATJ PDZ domains 8-10. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs).

73-119 2.67e-04

PDZ domain 1 of the canonical isoform 1 of PDZ domain containing 7 (PDZD7), and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 1 of the long isoform 1 of PDZD7, and related domains. PDZD7 is critical for the organization of Usher syndrome type 2 (USH2) complex. Usher syndrome is the leading cause of hereditary sensory deaf-blindness in humans; USH2 is the most common sub-type. Formation of the USH2 complex is based upon heterodimerization between PDZD7 and whirlin (another PDZ domain-containing protein) and a subsequent dynamic interplay between USH2 proteins via their multiple PDZ domains. The PDZD7 PDZ2 domain binds GPR98 (also known as VLGR1) and usherin (USH2A). PDZD7 and whirlin form heterodimers through their multiple PDZ domains; whirlin and PDZD7 interact with usherin and GPR98 to form an interdependent ankle link complex. PDZD7 also interacts with myosin VIIa. PDZD7 also forms homodimers through its PDZ2 domain. Various isoforms of PDZD7 produced by alternative splicing have been identified; this subgroup includes the first PDZ domain of the canonical isoform of PDZD7- isoform 1. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This PDZD7-like family PDZ1 domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2), arranged in the order: beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F.

periplasmic serine protease, Do/DeqQ family; This family consists of a set proteins various designated DegP, heat shock protein HtrA, and protease DO. The ortholog in Pseudomonas aeruginosa is designated MucD and is found in an operon that controls mucoid phenotype. This family also includes the DegQ (HhoA) paralog in E. coli which can rescue a DegP mutant, but not the smaller DegS paralog, which cannot. Members of this family are located in the periplasm and have separable functions as both protease and chaperone. Members have a trypsin domain and two copies of a PDZ domain. This protein protects bacteria from thermal and other stresses and may be important for the survival of bacterial pathogens.// The chaperone function is dominant at low temperatures, whereas the proteolytic activity is turned on at elevated temperatures.

MAST4 belongs to the MAST family kinases, which include MAST1-4. These MAST proteins contain a DUF1908 domain, a serine/threonine kinase domain, a AGC-kinase C-terminal domain, and a PDZ domain. MAST4 is a component of the AICD-MAST4-FOXO1-RTKN2 neuroprotective pathway; MAST4 phosphorylation of forkhead box protein O1 (FOXO1) regulates rhotekin 2 (RTKN2) expression. As this pathway is repressed in Alzheimer's Disease (AD), MAST4 may play a role in preventing AD pathogenesis.

PDZ domain 9 of multi-PDZ-domain protein 1 (MUPP1) and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 9 of MUPP1. MUPP1 and PATJ serve as scaffolding proteins linking different proteins and protein complexes involved in the organization of tight junctions and epithelial polarity. MUPP1 contains an L27 (Lin-2 and Lin-7 binding) domain and 13 PDZ domains. PATJ (also known as INAD-like) contains an L27 domain and ten PDZ domains. PATJ lacks 3 PDZ domains seen in MUPP1: PDZ6, PDZ9, and PDZ13. This MuPP1-like PDZ9 domain is therefore absent from PATJ. MUPP1 and PATJ share several binding partners, including junctional adhesion molecules (JAM), zonula occludens (ZO)-3, Pals1 (protein associated with Lin-7), Par (partitioning defective)-6 proteins, and nectins (adherence junction adhesion molecules). PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs).

PDZD11 (also known as ATPase-interacting PDZ protein, plasma membrane calcium ATPase-interacting single-PDZ protein, PMCA-interacting single-PDZ protein, PISP) is involved in the dynamic assembly of apical junctions (AJs). It is recruited by PLEKHA7 to AJs to promote the efficient junctional recruitment and stabilization of nectins, and the efficient early phases of assembly of AJs in epithelial cells. The PDZD11 PDZ domain binds nectin-1 and nectin-3. PDZD11 also binds to a PDZ binding motif located in the C-terminal tail of the human sodium-dependent multivitamin transporter, to the cytoplasmic tail of the Menkes copper ATPase ATP7A, and to the cytoplasmic tail of all plasma membrane Ca2+-ATPase b-splice variants. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs).

PDZ domain 6 of PDZ domain containing 2 (PDZD2), PDZ domain 3 of human pro-interleukin-16 (isoform 1, 1332 AA), and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 6 of PDZD2, also known as KIAA0300, PIN-1, activated in prostate cancer (AIPC) and PDZ domain-containing protein 3 (PDZK3). PDZD2 has seven PDZ domains. PDZD2 is expressed at exceptionally high levels in the pancreas and certain cancer tissues, such as prostate cancer. It promotes the proliferation of insulinoma cells and is upregulated during prostate tumorigenesis. In osteosarcoma (OS), the microRNA miR-363 acts as a tumor suppressor by inhibiting PDZD2. This family also includes the third PDZ domain (PDZ3) of human pro-interleukin-16 (isoform 1, also known as nPro-IL-16). Precursor IL-16 is cleaved to produce pro-IL-16 and C-terminal mature IL-16. Pro-IL-16 functions as a regulator of T cell growth; mature IL-16 is a CD4 ligand that induces chemotaxis and CD25 expression in CD4+ T cells. IL-16 bioactivity has been closely associated with the progression of several different cancers. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands.

circularly permuted PDZ domain of Bacillus subtilis HtrA-type serine proteases HtrA, HtrB, and YyxA and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of Bacillus subtilis HtrA/YkdA, HtrB/YvtA and YyxA/YycK, and related domains. HtrA-type serine proteases participate in folding and degradation of aberrant proteins, and in processing and maturation of native proteins. HtrA, HtrB, and YyxA have a single transmembrane domain at the N-terminus and a PDZ domain at the C-terminus. Expression of htrA and htrB genes is induced both by heat shock and by secretion stress (by a common) mechanism; yyxA is neither heat shock nor secretion stress inducible. HtrA and HtrB may have overlapping cellular functions; YyxA may have a cellular function distinct from the other two proteases or have the same function but under different conditions. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains and as well as those with circular permutations and domain swapping of beta-strands. The canonical PDZ domain contains six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2); arranged as A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F. This BsHtrA-like PDZ domain is a circularly permuted PDZ domain which places beta-strand A on the C-terminus. Another permutation exists in the PDZ superfamily which places both beta-strands A and B on the C-terminus.

PTPN13 regulates negative apoptotic signaling and mediates phosphoinositide 3-kinase (PI3K) signaling. PTPN13 has five PDZ domains. Proteins known to interact with PTPN13 PDZ domains include: PLEKHA1 and PLEKHA2 via PTPN13-PDZ domain 1, Fas receptor and thyroid receptor-interacting protein 6 via PTPN13-PDZ domain 2, nerve growth factor receptor and protein kinase N2 via PTPN13-PDZ domain 3, PDZ and LIM domain 4 (PDLIM4) via PTPN13-PDZ domains 2 and 4, and brain calpain-2 via PTPN13-PDZ domains 3, 4 and 5. Calpain-2-mediated PTPN13 fragments may be involved in abnormal tau aggregation and increased risk for Alzheimer's disease. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). FRMPD2 is localized in the basolateral membranes of polarized epithelial cells and is associated with tight junction formation and immune response; it contains 3 PDZ domains). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands.

AFDN belongs to the adhesion system, probably together with the E-cadherin-catenin system, that plays a role in the organization of homotypic, interneuronal, and heterotypic cell-cell adherens junctions. The AFDN PDZ domain interaction partners include poliovirus receptor-related protein PRR2/nectin, the junctional adhesion molecule (JAM), the breakpoint-cluster-region protein (BCR), connexin36 (Cx36), and a subset of Eph-related receptor tyrosine kinases; it can also bind low molecular weight ligands, in competition with a natural peptide ligand. Other AFDN-binding proteins have been identified. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This AFDN family domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2), arranged in the order: beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F.

RapGEF2 and RapGEF6 constitute a subfamily of guanine nucleotide exchange factors (GEFs) for RAP small GTPases that is characterized by the possession of the PDZ and Ras/Rap-associating domains. They activate Rap small GTPases, by catalyzing the release of GDP from the inactive GDP-bound forms, thereby accelerating GTP loading to yield the active GTP-bound forms. The PDZ domain of RapGEF6 (also known as PDZ-GEF2) binds junctional adhesion molecule A (JAM-A). PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands.

PDZ-LIM family proteins (also known as Zasp PDZ domain proteins) are involved in the rearrangement of the actin cytoskeleton; they mediate association with the cytoskeleton through alpha-actinin as well as with other proteins involved in signal transduction pathways. Members of this family include PDLIM1 (also known as C-terminal LIM domain protein 1, elfin, LIM domain protein CLP-36), PDLIM2 (also known as PDZ-LIM protein mystique), PDLIM3 (also known as actinin-associated LIM protein, alpha-actinin-2-associated LIM protein, ALP), PDLIM4 (also known as LIM protein RIL, Reversion-induced LIM protein), PDLIM5 (also known as enigma homolog, ENH, enigma-like PDZ and LIM domains protein), PDLIM6 (also known as LIM domain-binding protein 3, ZASP, Cypher, Oracle), and PDLIM7 (also known as PDZ and LIM domain protein 7, LIM mineralization protein, LMP; protein enigma). PDLIM1 has been shown to negatively regulate NF-kappaB-mediated signaling in the cytoplasm. PDLIM7 negatively regulates p53 through binding murine double minute 2 (MDM2). The PDZ domains of PDZ-LIM family proteins PDLIM1, 2, 3, 5, 6, 7 have been shown to bind actin. Other PDZ-LIM family PDZ domain binding partners include thyroid receptor interacting protein-6 (PDLIM4-PDZ), the LIM domain of PDLIM4 (PDLIM4-PDZ), tropomyosin (PDLIM7-PDZ), myotilin and calsarcin 1 (PDLIM6-PDZ), and proteins from the myotilin and FATZ (calsarcin/myozenin) families (PDLIM1, 3, 4, 6 PDZ domains).

83-145 1.12e-03

circularly permuted second PDZ domain (PDZ2) of Escherichia coli periplasmic serine endoprotease DegP and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 2 of Escherichia coli DegP (also known as heat shock protein DegP and Protease Do), and related domains. DegP belongs to the HtrA family of housekeeping proteases. It acts as a protease, degrading transiently denatured and unfolded or misfolded proteins which accumulate in the periplasm following heat shock or other stress conditions, and as a molecular chaperone at low temperatures. DegP has two PDZ domains in addition to the protease domain; its PDZ1 domain is responsible for the identifying the distinct substrate sequences that affect degradation (degron) of the substrate sequence, and its PDZ2 domain is responsible for the combining with other DegP monomers to form a stable oligomer structure. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains and as well as those with circular permutations and domain swapping of beta-strands. The canonical PDZ domain contains six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2); arranged as A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F. This DegP family PDZ domain 2 is a circularly permuted PDZ domain which places beta-strand A on the C-terminus. Another permutation exists in the PDZ superfamily which places both beta-strands A and B on the C-terminus.

92-144 1.12e-03

periplasmic serine protease, Do/DeqQ family; This family consists of a set proteins various designated DegP, heat shock protein HtrA, and protease DO. The ortholog in Pseudomonas aeruginosa is designated MucD and is found in an operon that controls mucoid phenotype. This family also includes the DegQ (HhoA) paralog in E. coli which can rescue a DegP mutant, but not the smaller DegS paralog, which cannot. Members of this family are located in the periplasm and have separable functions as both protease and chaperone. Members have a trypsin domain and two copies of a PDZ domain. This protein protects bacteria from thermal and other stresses and may be important for the survival of bacterial pathogens.// The chaperone function is dominant at low temperatures, whereas the proteolytic activity is turned on at elevated temperatures.

PDZ domain of MYO18A protein, and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of MYO18 protein and related domains. MYO18 (also known as myosin XVIIIA, KIAA0216, MysPDZ), a member of the myosin superfamily, is involved in regulating cell protrusion and migration, and Golgi trafficking and morphology, and is required for myoblast adhesion and muscle integrity. The MYO18A/MRCK/LRAP35a complex regulates actomyosin retrograde flow in cell protrusion and migration; the PtdIns(4)P/GOLPH3/MYO18A/F-actin complex is a hub for signals that regulate Golgi trafficking function. The MYO18A PDZ domain binds p190Rho-guanine nucleotide exchange factor (p190RhoGEF), Golgin45, and leucine repeat adaptor protein 1 (Lurap1, also known as Lrap35a). PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs).

PDZ domain 3 of PDZ domain containing 2 (PDZD2), PDZ domain 1 of human pro-interleukin-16 (isoform 1, 1332 AA), and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 3 of PDZD2, also known as KIAA0300, PIN-1, activated in prostate cancer (AIPC) and PDZ domain-containing protein 3 (PDZK3). PDZD2 has seven PDZ domains. PDZD2 is expressed at exceptionally high levels in the pancreas and certain cancer tissues, such as prostate cancer. It promotes the proliferation of insulinoma cells and is upregulated during prostate tumorigenesis. In osteosarcoma (OS), the microRNA miR-363 acts as a tumor suppressor by inhibiting PDZD2. This family also includes the first PDZ domain (PDZ1) of human pro-interleukin-16 (isoform 1, also known as nPro-Il-16; 1332 amino-acid protein). Precursor IL-16 is cleaved to produce pro-IL-16 and mature IL-16 (derived from the C-terminal 121 AA). Pro-IL-16 functions as a regulator of T cell growth; mature IL-16 is a CD4 ligand that induces chemotaxis and CD25 expression in CD4+ T cells. IL-16 bioactivity has been closely associated with the progression of several different cancers. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This PDZD2-like family PDZ3 domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2), arranged in the order: beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F.

MUPP1 and PATJ serve as scaffolding proteins linking different proteins and protein complexes involved in the organization of tight junctions and epithelial polarity. MUPP1 contains an L27 (Lin-2 and Lin-7 binding) domain and 13 PDZ domains. PATJ (also known as INAD-like) contains an L27 domain and ten PDZ domains. PATJ lacks 3 PDZ domains seen in MUPP1: PDZ6, PDZ9, and PDZ13. This MuPP1-like PDZ6 domain is therefore absent from PATJ. MUPP1 and PATJ share several binding partners, including junctional adhesion molecules (JAM), zonula occludens (ZO)-3, Pals1 (protein associated with Lin-7), Par (partitioning defective)-6 proteins, and nectins (adherence junction adhesion molecules).

PDZ domain of neurabin-1 and neurabin-2, and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of neurabin-1 (also known as protein phosphatase 1 regulatory subunit 9A) and neurabin-2 (also known as spinophilin, and protein phosphatase 1 regulatory subunit 9B), and related domains. Neurabin-1 and neurabin-2 are neuronal scaffolding proteins that play important roles in the regulation of synaptic transmission through their ability to interact with and target protein phosphatase 1 (PP1) to dendritic spines where PP1 dephosphorylates and inactivates glutamate receptors. Neurabin-2 interacts with multiple other synaptic proteins, including synaptic signaling and scaffolding proteins (e.g., GluN1 and SAPAP3) and cytoskeletal proteins (e.g., neurofilament medium polypeptide, NF-M). Neurabin-1 and neurabin-2 also binds F-actin. Other binding partners of neurabin-1 include adenosine A1 receptor (A1R), SAD-1 kinase and 70 kDa ribosomal protein S6 kinase (p70-S6K). This PDZ domain is immediately C-terminal to the PP1 binding domain. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This neurabin-like PDZ domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2), arranged in the order: beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F.

71-136 2.06e-03

PDZ domain 1 of PDZ domain-containing RING finger protein 4 (PDZRN4), PDZRN3-B, and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 1 of PDZRN4, PDZRN3-B, and related domains. PDZRN4 (also known as ligand of numb protein X 4, and SEMACAP3-like protein) contains an N-terminal RING domain and two tandem repeat PDZ domains. It is involved in the progression of cancer, including human liver cancer and breast cancer, and may contribute to the tumorigenesis of rectal adenocarcinoma. Danio rerio PDZRN3-B may participate in neurogenesis: the first PDZ domain of Danio rerio Pdzrn3 interacts with Kidins220 (Kinase D-interacting substrate 220 kD, also named Ankyrin Repeat-Rich Membrane Spanning), a crucial mediator of signal transduction in neural tissues. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands.

73-147 6.06e-03

PDZ domain 1 of human discs large homolog 1 (Dlg1), Dlg2, and Dlg4, Drosophila disc large (Dlg), and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 1 of Drosophila Dlg1, human Dlg1,2, and 4 and related domains. Dlg1 (also known as synapse-associated protein Dlg197 or SAP-97), Dlg2 (also known as channel-associated protein of synapse-110, postsynaptic density protein 93, or PSD-93), Dlg4 (also known as postsynaptic density protein 95, PSD-95, synapse-associated protein 90, or SAP-90) each have 3 PDZ domains and belong to the membrane-associated guanylate kinase family. Dlg1 regulates antigen receptor signaling and cell polarity in lymphocytes, B-cell proliferation and antibody production, and TGFalpha bioavailability; its PDZ3 domain binds pro-TGFalpha, and its PDZ2 domain binds the TACE metalloprotease responsible for cleaving pro-TGFalpha to a soluble form. Dlg2 is involved in N-methyl-D-aspartate (NMDA) receptor signaling. It regulates surface expression of NMDA receptors in dorsal horn neurons of the spinal cord, and it also interacts with NMDA receptor subunits and with Shaker-type K+ channel subunits to cluster into a channel complex. Dlg4 PDZ1 domain binds NMDA receptors, and its PDZ2 domain binds neuronal nitric oxide synthase (nNOS), forming a complex in neurons. The Drosophila Scribble complex (Scribble, Dlg, and lethal giant larvae) plays a role in apico-basal cell polarity, and in other forms of polarity, including regulation of the actin cytoskeleton, cell signaling and vesicular trafficking, and in tumor development. Postsynaptic targeting of Drosophila DLG requires interactions mediated by the first two PDZ domains. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This Dlg-like family PDZ1 domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2), arranged in the order: beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F.

91-172 7.27e-03

circularly permuted PDZ domain 1 (PDZ-N) of Escherichia coli Regulator of sigma-E protease (RseP) and related domains; Permuted PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of ResP (also known as Site-2 protease RseP, and YaeL) and related domains. RseP is involved in the regulation of an extracytoplasmic stress response through the cleavage of membrane-spanning anti-stress-response transcription factor (anti-sigmaE) protein RseA; it cleaves the peptide bond between the critical alanine and cysteine in the transmembrane region of RseA, releasing the cytoplasmic domain of RseA with it associated sigmaE. RseP contains two tandem-arranged periplasmic PDZ domains (PDZ-N/PDZ1 and PDZ-C/PDZ2) which act to negatively regulate protease action on intact RseA; they serve as a size-exclusion filter which prevents the access of an intact RseA into the active site of RseP. PDZ domains usually bind in sequence-specific manner to short peptide sequences located at the C-terminal of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains and as well as those with circular permutations and domain swapping of beta-strands. The canonical PDZ domain contains six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2); arranged as beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F. This RseP family PDZ domain is a circularly permuted PDZ domain which places both beta-strands A and B at the C-terminus. Another permutation exists in the PDZ superfamily which places beta-strand A at the C-terminus.

75-136 9.28e-03

PDZ domain of tyrosine-protein phosphatase non-receptor type 3 (PTPN3), tyrosine-protein phosphatase non-receptor type 4 (PTNP4), and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of PTPN3, PTPN4 and related domains. PTPN3 (also known as protein-tyrosine phosphatase H1, PTP-H1) has a tumor-suppressive or a tumor-promoting role in many cancers. It serves as a specific phosphatase for the MAP kinase p38gamma; the two interact via their PDZ domains and cooperate to promote Ras-induced oncogenesis. Interaction partners of the PTPN3 PDZ domain include p38gamma and human papillomavirus E6 oncoprotein. PTPN4 (also known as protein-tyrosine phosphatase MEG1) plays a role in immunity, learning, synaptic plasticity or cell homeostasis. p38gamma is also an interaction partner of the PTPN4 PDZ domain: PTPN4 regulates neuronal cell homeostasis by protecting neurons against apoptosis; binding of the C terminus of p38gamma to the PDZ domain of PTPN4, antagonizes the catalytic autoinhibition of PTPN4, leading to cell apoptosis. Other interaction partners of the PTPN4 PDZ domain include glutamate receptor subunit GluN2A, and RABV strain G protein, among others. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This PTPN3-like family domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2), arranged in the order: beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F.
