 160-265 3.31e-69

The phosphoinositide binding Phox Homology domain of Sorting Nexin 27; The PX domain is a phosphoinositide (PI) binding module present in many proteins with diverse functions. Sorting nexins (SNXs) make up the largest group among PX domain containing proteins. They are involved in regulating membrane traffic and protein sorting in the endosomal system. The PX domain of SNXs binds PIs and targets the protein to PI-enriched membranes. SNXs differ from each other in PI-binding specificity and affinity, and the presence of other protein-protein interaction domains, which help determine subcellular localization and specific function in the endocytic pathway. SNX27 contains an N-terminal PDZ domain followed by a PX domain and a Ras-Associated (RA) domain. It binds G protein-gated potassium (Kir3) channels, which play a role in neuronal excitability control, through its PDZ domain. SNX27 downregulates Kir3 channels by promoting their movement in the endosome, reducing surface expression and increasing degradation. SNX27 also associates with 5-hydroxytryptamine type 4 receptor (5-HT4R), cytohesin associated scaffolding protein (CASP), and diacylglycerol kinase zeta, and may play a role in their intracellular trafficking and endocytic recycling. The SNX27 PX domain preferentially binds to phosphatidylinositol-3-phosphate (PI3P) and is important for targeting to the early endosome.

 425-526 7.91e-67

Atypical FERM-like domain C-lobe of Sorting nexin 27; SNX27 is localized to early endosomes and known to regulate the intracellular trafficking of ion channels and receptors. SNX27 contain a N-terminal PDZ domain, a PX domain, and a FERM-like domain. SNX27 regulates trafficking of a PAK interacting exchange factor-G protein-coupled receptor kinase interacting protein complex via its PDZ domain interaction. Sorting nexin 27 interacts with multidrug resistance-associated protein 4 (MRP4). SNX27 binds Ras GTPase through its FERM-like domains. The PX domain of SNXs binds PIs and targets the protein to PI-enriched membranes. These interactions place the PX-FERM-like proteins at a hub of endosomal sorting and signaling processes. These proteins participate in a network of interactions that will impact on both endosomal protein trafficking and compartment specific Ras signaling cascades. The typical FERM domain has a cloverleaf tripart structure composed of: (1) FERM_N (A-lobe or F1); (2) FERM_M (B-lobe, or F2); and (3) FERM_C (C-lobe or F3). The C-lobe/F3 within the FERM domain is part of the PH domain family. FERM domains are found in cytoskeletal-associated proteins such as ezrin, moesin, radixin, 4.1R, and merlin. These proteins provide a link between the membrane and cytoskeleton and are involved in signal transduction pathways. The FERM domain is also found in protein tyrosine phosphatases (PTPs), the tyrosine kinases FAK and JAK, in addition to other proteins involved in signaling. This domain is structurally similar to the PH and PTB domains and consequently is capable of binding to both peptides and phospholipids at different sites.

 42-134 6.50e-64

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. This SNX27-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.

 273-365 2.58e-54

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in sorting nexin protein 27 (SNX27); SNX27 is a member of the family of cytoplasmic sorting nexin adaptor proteins that regulate endosomal trafficking of cell surface proteins. In addition to a PX (Phox homology) domain that regulates its endosomal localization, SNX27 has a unique PDZ (Psd-95/Dlg/ZO1) domain and an atypical FERM (4.1, ezrin, radixin, moesin) domain that both function to bind short peptide sequence motifs in the cytoplasmic domains of the cargo receptors. The FERM domain is made up of three sub-domains, F1, F2, and F3. This family corresponds to the F1 sub-domain, which is also called the N-terminal ubiquitin-like structural domain of the FERM domain (FERM_N).

 81-162 2.33e-06

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.

 160-265 3.31e-69

The phosphoinositide binding Phox Homology domain of Sorting Nexin 27; The PX domain is a phosphoinositide (PI) binding module present in many proteins with diverse functions. Sorting nexins (SNXs) make up the largest group among PX domain containing proteins. They are involved in regulating membrane traffic and protein sorting in the endosomal system. The PX domain of SNXs binds PIs and targets the protein to PI-enriched membranes. SNXs differ from each other in PI-binding specificity and affinity, and the presence of other protein-protein interaction domains, which help determine subcellular localization and specific function in the endocytic pathway. SNX27 contains an N-terminal PDZ domain followed by a PX domain and a Ras-Associated (RA) domain. It binds G protein-gated potassium (Kir3) channels, which play a role in neuronal excitability control, through its PDZ domain. SNX27 downregulates Kir3 channels by promoting their movement in the endosome, reducing surface expression and increasing degradation. SNX27 also associates with 5-hydroxytryptamine type 4 receptor (5-HT4R), cytohesin associated scaffolding protein (CASP), and diacylglycerol kinase zeta, and may play a role in their intracellular trafficking and endocytic recycling. The SNX27 PX domain preferentially binds to phosphatidylinositol-3-phosphate (PI3P) and is important for targeting to the early endosome.

 425-526 7.91e-67

Atypical FERM-like domain C-lobe of Sorting nexin 27; SNX27 is localized to early endosomes and known to regulate the intracellular trafficking of ion channels and receptors. SNX27 contain a N-terminal PDZ domain, a PX domain, and a FERM-like domain. SNX27 regulates trafficking of a PAK interacting exchange factor-G protein-coupled receptor kinase interacting protein complex via its PDZ domain interaction. Sorting nexin 27 interacts with multidrug resistance-associated protein 4 (MRP4). SNX27 binds Ras GTPase through its FERM-like domains. The PX domain of SNXs binds PIs and targets the protein to PI-enriched membranes. These interactions place the PX-FERM-like proteins at a hub of endosomal sorting and signaling processes. These proteins participate in a network of interactions that will impact on both endosomal protein trafficking and compartment specific Ras signaling cascades. The typical FERM domain has a cloverleaf tripart structure composed of: (1) FERM_N (A-lobe or F1); (2) FERM_M (B-lobe, or F2); and (3) FERM_C (C-lobe or F3). The C-lobe/F3 within the FERM domain is part of the PH domain family. FERM domains are found in cytoskeletal-associated proteins such as ezrin, moesin, radixin, 4.1R, and merlin. These proteins provide a link between the membrane and cytoskeleton and are involved in signal transduction pathways. The FERM domain is also found in protein tyrosine phosphatases (PTPs), the tyrosine kinases FAK and JAK, in addition to other proteins involved in signaling. This domain is structurally similar to the PH and PTB domains and consequently is capable of binding to both peptides and phospholipids at different sites.

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. This SNX27-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.

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in sorting nexin protein 27 (SNX27); SNX27 is a member of the family of cytoplasmic sorting nexin adaptor proteins that regulate endosomal trafficking of cell surface proteins. In addition to a PX (Phox homology) domain that regulates its endosomal localization, SNX27 has a unique PDZ (Psd-95/Dlg/ZO1) domain and an atypical FERM (4.1, ezrin, radixin, moesin) domain that both function to bind short peptide sequence motifs in the cytoplasmic domains of the cargo receptors. The FERM domain is made up of three sub-domains, F1, F2, and F3. This family corresponds to the F1 sub-domain, which is also called the N-terminal ubiquitin-like structural domain of the FERM domain (FERM_N).

The typical FERM domain has a cloverleaf tripart structure composed of: (1) FERM_N (A-lobe or F1); (2) FERM_M (B-lobe, or F2); and (3) FERM_C (C-lobe or F3). The C-lobe/F3 within the FERM domain is part of the PH domain family. FERM domains are found in cytoskeletal-associated proteins such as ezrin, moesin, radixin, 4.1R, and merlin. These proteins provide a link between the membrane and cytoskeleton and are involved in signal transduction pathways. The FERM domain is also found in protein tyrosine phosphatases (PTPs), the tyrosine kinases FAK and JAK, in addition to other proteins involved in signaling. This domain is structurally similar to the PH and PTB domains and consequently is capable of binding to both peptides and phospholipids at different sites.

 273-363 2.20e-42

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in PX-FERM family sorting nexin proteins; This family includes three endosome-associated PX (Phox homology) and FERM (Band 4.1, ezrin, radixin, moesin) domain-containing proteins called sorting nexin (SNX) 17, SNX27, and SNX31, which are modular peripheral membrane proteins acting as central scaffolds mediating protein-lipid interactions, cargo binding, and regulatory protein recruitment. They are key regulators of endosomal recycling and bind conserved NPX(Y/F) peptide sorting motifs in transmembrane cargos via an atypical FERM domain. The FERM domain is made up of three sub-domains, F1, F2, and F3. This family corresponds to the F1 sub-domain, which is also called the N-terminal ubiquitin-like structural domain of the FERM domain (FERM_N).

 41-136 1.16e-28

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. This SHANK-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.

 42-134 8.55e-26

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.

 165-263 1.45e-20

The Phox Homology domain, a phosphoinositide binding module; The PX domain is a phosphoinositide (PI) binding module involved in targeting proteins to membranes. Proteins containing PX domains interact with PIs and have been implicated in highly diverse functions such as cell signaling, vesicular trafficking, protein sorting, lipid modification, cell polarity and division, activation of T and B cells, and cell survival. Many members of this superfamily bind phosphatidylinositol-3-phosphate (PI3P) but in some cases, other PIs such as PI4P or PI(3,4)P2, among others, are the preferred substrates. In addition to protein-lipid interaction, the PX domain may also be involved in protein-protein interaction, as in the cases of p40phox, p47phox, and some sorting nexins (SNXs). The PX domain is conserved from yeast to humans and is found in more than 100 proteins. The majority of PX domain-containing proteins are SNXs, which play important roles in endosomal sorting.

 165-262 5.95e-19

The phosphoinositide binding Phox Homology domain of Sorting Nexins 17 and 31; The PX domain is a phosphoinositide (PI) binding module present in many proteins with diverse functions. Members of this subfamily include sorting nexin 17 (SNX17), SNX31, and similar proteins. They contain an N-terminal PX domain followed by a truncated FERM (4.1, ezrin, radixin, and moesin) domain and a unique C-terminal region. SNXs make up the largest group among PX domain containing proteins. They are involved in regulating membrane traffic and protein sorting in the endosomal system. The PX domain of SNXs binds PIs and targets the protein to PI-enriched membranes. SNXs differ from each other in PI-binding specificity and affinity, and the presence of other protein-protein interaction domains, which help determine subcellular localization and specific function in the endocytic pathway. SNX17 is known to regulate the trafficking and processing of a number of proteins. It binds some members of the low-density lipoprotein receptor (LDLR) family such as LDLR, VLDLR, ApoER2, and others, regulating their endocytosis. It also binds P-selectin and may regulate its lysosomal degradation. SNX17 is highly expressed in neurons. It binds amyloid precursor protein (APP) and may be involved in its intracellular trafficking and processing to amyloid beta peptide, which plays a central role in the pathogenesis of Alzheimer's disease. The biological function of SNX31 is unknown.

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.

PDZ domain 2 of tyrosine kinase PTPN13, FERM and PDZ domain-containing protein 2 (FRMPD2), and similar domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 2 of human PTPN13, and related domains. PTPN13, also known as Fas-associated protein-tyrosine phosphatase 1 (FAP-1), protein-tyrosine phosphatase 1E (PTP-E1), and protein-tyrosine phosphatase (PTPL1), negatively regulates FAS-mediated apoptosis and NGFR-mediated pro-apoptotic signaling, and may also regulate phosphoinositide 3-kinase (PI3K) signaling. It contains 5 PDZ domains; interaction partners of its second PDZ domain (PDZ2) include the Fas receptor (TNFRSF6) and thyroid receptor-interacting protein 6 (TRIP6). The second PDZ (PDZ2) domain, but not PDZ1 or PDZ3, of FRMPD2 binds to GluN2A and GluN2B, two subunits of N-methyl-d-aspartic acid (NMDA) receptors. Other binding partners of the FRMPDZ2 PDZ2 domain include NOD2, and catenin family members, delta catenin (CTNND2), armadillo repeat gene deleted in velo-cardio-facial syndrome (ARVCF) and p0071 (also known as plakophilin 4; PKP4). 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.

RGS12 downregulates GPCR signal transduction by increasing the GTPase activity of G-protein alpha subunits, thereby driving G-proteins into their inactive GDP-bound form. The RGS12 PDZ domain can bind selectively to C-terminal (A/S)-T-X-(L/V) motifs as found within both the CXCR2 IL-8 receptor, and the alternative 3' exon form of RGS12. 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 membrane-associated guanylate kinase inverted 1 (MAGI-1), MAGI-2, and MAGI-3, and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 3 of MAGI1, 2, 3 (MAGI is also known as Membrane-associated guanylate kinase, WW and PDZ domain-containing protein) and related domains. 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 PDZ3 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 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). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands.

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.

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.

GRIP1 and GRIP2 each have 7 PDZ domains. The interaction of GRIP1 and GRIP2 with GluA2/3 (AMPAR subunit) regulates AMPAR trafficking and synaptic targeting. GRIP1 has an essential role in regulating AMPAR trafficking during synaptic plasticity and learning and memory. GRIP1 and GRIP2 interact with a variety of other proteins associated with protein trafficking and internalization, for example GRIP1 also interacts with KIF5 (also known as kinesin 1), EphB receptors, scaffold protein liprin-alpha, and the rasGEF GRASP-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).

PDZ domain 1 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 1 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. This Scribble-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.

 42-135 5.35e-12

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.

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.

 173-263 1.71e-11

The phosphoinositide binding Phox Homology domain of yeast MDM1p; The PX domain is a phosphoinositide binding (PI) module present in many proteins with diverse functions such as cell signaling, vesicular trafficking, protein sorting, and lipid modification, among others. Yeast MDM1p is a filament-like protein localized in punctate structures distributed throughout the cytoplasm. It plays an important role in nuclear and mitochondrial transmission to daughter buds. Members of this subfamily show similar domain architectures as some sorting nexins (SNXs). Some members are similar to SNX19 in that they contain an N-terminal PXA domain, a central PX domain, and a C-terminal domain that is conserved in some SNXs. Others are similar to SNX13 and SNX14, which also harbor these three domains as well as a regulator of G protein signaling (RGS) domain in between the PXA and PX domains. SNXs make up the largest group among PX domain containing proteins. They are involved in regulating membrane traffic and protein sorting in the endosomal system. The PX domain of SNXs binds PIs and targets the protein to PI-enriched membranes. SNXs differ from each other in PI-binding specificity and affinity, and the presence of other protein-protein interaction domains, which help determine subcellular localization and specific function in the endocytic pathway.

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.

PDZ domain 1 of protein tyrosine phosphatase non-receptor type 13 (PTPN13),FERM and PDZ domain-containing protein 2 (FRMPD2), and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 1 of PTPN13 [also known as Fas-associated protein-tyrosine phosphatase 1 (FAP-1), protein-tyrosine phosphatase 1E (PTP-E1), and protein-tyrosine phosphatase (PTPL1)], FRMPD2 (also known as PDZ domain-containing protein 4; PDZ domain-containing protein 5C), and related domains. 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). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This PTPN13 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.

GRIP1 and GRIP2 each have 7 PDZ domains. The interaction of GRIP1 and GRIP2 with GluA2/3 (AMPAR subunit) regulates AMPAR trafficking and synaptic targeting. GRIP1 has an essential role in regulating AMPAR trafficking during synaptic plasticity and learning and memory. GRIP1 and GRIP2 interact with a variety of other proteins associated with protein trafficking and internalization, for example GRIP1 also interacts with KIF5 (also known as kinesin 1), EphB receptors, scaffold protein liprin-alpha, and the rasGEF GRASP-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.

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.

 42-134 3.55e-10

PDZ domain of partitioning defective 6 (Par6), Drosophila Rho GTPase-activating protein 100F (RhoGAP100F), and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of Par6 (also known as PAR6 or Par-6), RhoGAP100F, and related domains. Par6 is part of a conserved machinery that directs metazoan cell polarity, a process necessary for the function of diverse cell types. Par6 forms a cell polarity-regulatory complex with atypical protein kinase C (aPKC) and Par3. Par6 can also directly associate with PALS1 (proteins associated with Lin7, also known as Stardust) providing a link between the Par3/aPKC/Par6 complex and the PALS1-PATJ (protein-associated TJ) complex. Binding partners of the Par6-PDZ domain include Par3, PALS1/Stardust; leucine-rich repeat-containing protein netrin-G ligand-2 (NGL-2), human crumbs (CRB3) involve in the morphogenesis of the tight junctions in mammalian epithelial cells, and PAR-6 co-operates with the Par6 semi-CRIB domain to bind CDC42. CDC42 regulates the Par6 PDZ domain through an allosteric CRIB-PDZ transition. Drosophila RhoGAP100F, also known as synapse defective protein 1 homolog (syd-1 homolog), is a GTPase activator for the Rho-type GTPases by converting them to an inactive GDP-bound form. The RhoGAP100F-PDZ domain binds the neurexin C terminus to control synapse formation at the Drosophila neuromuscular junction. 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 Par6-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.

 173-262 3.68e-10

The phosphoinositide binding Phox Homology domain of Sorting Nexins 20 and 21; The PX domain is a phosphoinositide (PI) binding module present in many proteins with diverse functions. Sorting nexins (SNXs) make up the largest group among PX domain containing proteins. They are involved in regulating membrane traffic and protein sorting in the endosomal system. The PX domain of SNXs binds PIs and targets the protein to PI-enriched membranes. SNXs differ from each other in PI-binding specificity and affinity, and the presence of other protein-protein interaction domains, which help determine subcellular localization and specific function in the endocytic pathway. This subfamily consists of SNX20, SNX21, and similar proteins. SNX20 interacts with P-Selectin glycoprotein ligand-1 (PSGL-1), a surface-expressed mucin that acts as a ligand for the selectin family of adhesion proteins. It may function in the sorting and cycling of PSGL-1 into endosomes. SNX21, also called SNX-L, is distinctly and highly-expressed in fetal liver and may be involved in protein sorting and degradation during embryonic liver development.

 273-359 4.53e-10

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in sorting nexin protein 17 (SNX17); SNX17 is a member of the family of cytoplasmic sorting nexin adaptor proteins that regulate endosomal trafficking of cell surface proteins. It localizes to early endosomes, and plays an important role in mediating endocytic internalization, recycling, and/or protection from lysosomal degradation of NPxY-motif containing cell surface proteins including amyloid precursor protein (APP), P-selectin, beta1-integrin, low density lipoprotein receptor (LDLR), LDLR related protein (Lrp1), ApoER2, and FEEL1. SNX17 also affects T cell activation by regulating T cell receptor and integrin recycling. SNX17 contains a PX (Phox homology) domain and a FERM (Band 4.1, ezrin, radixin, moesin) domain. The FERM domain is made up of three sub-domains, F1, F2, and F3. This family corresponds to the F1 sub-domain, which is also called the N-terminal ubiquitin-like structural domain of the FERM domain (FERM_N).

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.

Danio rerio Ptpn13 is a classical non-receptor-like PTP. 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 PTPN13-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.

Drosophila melanogaster Zasp52 (also known as Z band alternatively spliced PDZ-motif protein or Zasp) colocalizes with integrins at myotendinous junctions and with alpha-actinin at Z-disks and is required for muscle attachment as well as Z-disk assembly and maintenance. The Zasp52 actin-binding site includes the extended PDZ domain and the ZM region. The Zasp52-PDZ domain is required for myofibril assembly. 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).

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 PDZ13 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 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 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.

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).

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).

 165-263 1.94e-08

The phosphoinositide binding Phox Homology domain of SNARE proteins from fungi; The PX domain is a phosphoinositide (PI) binding module present in many proteins with diverse functions such as cell signaling, vesicular trafficking, protein sorting, and lipid modification, among others. This subfamily is composed of fungal proteins similar to Saccharomyces cerevisiae Vam7p. They contain an N-terminal PX domain and a C-terminal SNARE domain. The SNARE (Soluble NSF attachment protein receptor) family of proteins are integral membrane proteins that serve as key factors for vesicular trafficking. Vam7p is anchored at the vacuolar membrane through the specific interaction of its PX domain with phosphatidylinositol-3-phosphate (PI3P) present in bilayers. It plays an essential role in vacuole fusion. The PX domain is involved in targeting of proteins to PI-enriched membranes, and may also be involved in protein-protein interaction.

PDZ domain of synaptojanin-2-binding protein (SYNJ2BP), and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of SYNJ2BP, and related domains. 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. This SYNJ2BP-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 5 of membrane-associated guanylate kinase inverted 1 (MAGI-1), MAGI-2, and MAGI-3, and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 5 of MAGI1, 2, 3 (MAGI is also known as Membrane-associated guanylate kinase, WW and PDZ domain-containing protein) and related domains. 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, and belongs to this MAGI1,2,3-like family. 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).

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.

SNXs differ from each other in PI-binding specificity and affinity, and the presence of other protein-protein interaction domains, which help determine subcellular localization and specific function in the endocytic pathway. Some SNXs are localized in early endosome structures such as clathrin-coated pits, while others are located in late structures of the endocytic pathway. SNX20 interacts with P-Selectin glycoprotein ligand-1 (PSGL-1), a surface-expressed mucin that acts as a ligand for the selectin family of adhesion proteins. The PX domain of SNX20 binds PIs and targets the SNX20/PSGL-1 complex to endosomes. SNX20 may function in the sorting and cycling of PSGL-1 into endosomes.

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).

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 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).

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). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands.

 163-265 1.09e-07

The phosphoinositide binding Phox Homology domain of Sorting Nexin 10; The PX domain is a phosphoinositide (PI) binding module present in many proteins with diverse functions. Sorting nexins (SNXs) make up the largest group among PX domain containing proteins. They are involved in regulating membrane traffic and protein sorting in the endosomal system. The PX domain of SNXs binds PIs and targets the protein to PI-enriched membranes. SNXs differ from each other in PI-binding specificity and affinity, and the presence of other protein-protein interaction domains, which help determine subcellular localization and specific function in the endocytic pathway. Some SNXs are localized in early endosome structures such as clathrin-coated pits, while others are located in late structures of the endocytic pathway. SNX10 may be involved in the regulation of endosome homeostasis. Its expression induces the formation of giant vacuoles in mammalian cells.

 42-122 1.31e-07

PDZ domain of membrane palmitoylated protein 5 (MPP5), Drosophila Stardust, and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of MPP5, Drosophila Stardust, and related domains. MPP5 (also known as MAGUK p55 subfamily member 1, protein associated with Lin-7 1 or PALS1) and Drosophila Stardust are membrane-associated guanylate kinase (MAGUK)-like proteins that serve as signaling and scaffolding proteins, linking different proteins critical to the formation and maintenance of tight junctions (TJ) and apical-basal polarity. Apical-basal polarity determinants cluster in complexes; in particular, the Crumbs complex (Crb, MPP5, and PATJ) and the PAR/aPKC-complex (PAR-3, PAR-6, aPKC) determine the apical plasma membrane domain. Within the Crumbs complex, Crb is stabilized in the plasma membrane by MPP5, which in turn recruits PATJ and Lin-7 to the complex. MPP5 also links the Crumbs complex with the PAR/aPKC-complex. The Drosophila homolog of the Crumbs complex is the (CRB)-Stardust (Sdt)-Discs Lost (Dlt) complex. MPP5 also acts as an interaction partner for SARS-CoV envelope protein E, which results in delayed formation of TJs and dysregulation 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. This MPP5-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.

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).

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.

MPP3 (also known as MAGUK p55 subfamily member 3, erythrocyte membrane protein p55, or EMP55), MPP4 (also known as MAGUK p55 subfamily member 4 or Discs large homolog 6), and MPP7 (also known as MAGUK p55 subfamily member 7) are membrane-associated guanylate kinase (MAGUK)-like proteins. MPP3 is part of a cell adhesion protein complex including tumor suppressor CADM1 and actin-binding protein 4.1B. Participation in the Crumbs cell polarity complex has also been demonstrated for MPP7 in epithelial cells, and for MPP3 and MPP4 in the retina. MPP4 is needed for proper localization of plasma membrane calcium ATPases and maintenance of calcium homeostasis at the rod photoreceptor synaptic terminals. Binding partners of the MPP3 PDZ domain include nectin-3, serotonin 5-hydroxytryptamine, 5-HT(2C) receptor, and a cell adhesion protein, TSLC1 (tumor suppressor in lung cancer 1); fragments of MPP4 having the PDZ domain bind CRB (PDZ-SH3-GUK) and GABA transporter GAT1 (PDZ-SH3). 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).

They contain two PDZ domains (PDZ1 and PDZ2) which bind a variety of proteins: Arf GTPases (APBA1 and APBA2 PDZ2) and neurexin (APBA1 and APBA2 PDZ1 and 2) which are involved in vesicle docking and exocytosis; alpha1B subunit of N-type Ca2+ channel (APBA1 PDZ1) that is involved in ion channels; KIF17 (APBA1 PDZ1) that is involved in transport and traffic; and Alzheimer's disease related proteins, APP (APBA3 PDZ2), CCS (APBA1 PDZ2), NF-kappa-B/p65 (APBA2 PDZ2), presenilin-1 (APBA1 and APBA2 PDZ1 and PDZ2). 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 APBA1,3-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 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.

PDZ domain 3 of protein tyrosine phosphatase non-receptor type 13 (PTPN13), FERM and PDZ domain-containing protein 2 (FRMPD2), and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 3 of PTPN13 [also known as Fas-associated protein-tyrosine phosphatase 1 (FAP-1), protein-tyrosine phosphatase 1E (PTP-E1), and protein-tyrosine phosphatase (PTPL1)], FRMPD2 (also known as PDZ domain-containing protein 4; PDZ domain-containing protein 5C), and related domains. 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.

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.

 179-265 9.21e-07

The phosphoinositide binding Phox Homology domain of Sorting Nexin 8 and yeast Mvp1p; The PX domain is a phosphoinositide (PI) binding module present in many proteins with diverse functions. Sorting nexins (SNXs) make up the largest group among PX domain containing proteins. They are involved in regulating membrane traffic and protein sorting in the endosomal system. The PX domain of SNXs binds PIs and targets the protein to PI-enriched membranes. SNXs differ from each other in PI-binding specificity and affinity, and the presence of other protein-protein interaction domains, which help determine subcellular localization and specific function in the endocytic pathway. Some SNXs are localized in early endosome structures such as clathrin-coated pits, while others are located in late structures of the endocytic pathway. SNX8 and the yeast counterpart Mvp1p are involved in sorting and delivery of late-Golgi proteins, such as carboxypeptidase Y, to vacuoles.

The phosphoinositide binding Phox Homology domain of HS1BP3; The PX domain is a phosphoinositide (PI) binding module present in many proteins with diverse functions such as cell signaling, vesicular trafficking, protein sorting, and lipid modification, among others. Hematopoietic lineage cell-specific protein-1 (HS1) binding protein 3 (HS1BP3) associates with HS1 proteins through their SH3 domains, suggesting a role in mediating signaling. It has been reported that HS1BP3 might affect the IL-2 signaling pathway in hematopoietic lineage cells. Mutations in HS1BP3 may also be associated with familial Parkinson disease and essential tremor. HS1BP3 contains a PX domain, a leucine zipper, motifs similar to immunoreceptor tyrosine-based inhibitory motif and proline-rich regions. The PX domain interacts with PIs and plays a role in targeting proteins to PI-enriched membranes.

The phosphoinositide binding Phox Homology domain of Sorting Nexin 19; The PX domain is a phosphoinositide (PI) binding module present in many proteins with diverse functions. Sorting nexins (SNXs) make up the largest group among PX domain containing proteins. They are involved in regulating membrane traffic and protein sorting in the endosomal system. The PX domain of SNXs binds PIs and targets the protein to PI-enriched membranes. SNXs differ from each other in PI-binding specificity and affinity, and the presence of other protein-protein interaction domains, which help determine subcellular localization and specific function in the endocytic pathway. SNX19 contains an N-terminal PXA domain, a central PX domain, and a C-terminal domain that is conserved in some SNXs. These domains are also found in SNX13 and SNX14, which also contain a regulator of G protein signaling (RGS) domain in between the PXA and PX domains. SNX19 interacts with IA-2, a major autoantigen found in type-1 diabetes. It inhibits the conversion of phosphatidylinositol-4,5-bisphosphate [PI(4,5)P2] to PI(3,4,5)P3, which leads in the decrease of protein phosphorylation in the Akt signaling pathway, resulting in apoptosis. SNX19 may also be implicated in coronary heart disease and thyroid oncocytic tumors.

 43-132 1.62e-06

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.

 176-262 2.03e-06

The phosphoinositide binding Phox Homology Domain of Class II Phosphoinositide 3-Kinases; The PX domain is a phosphoinositide (PI) binding module present in many proteins with diverse functions. The Phosphoinositide 3-Kinase (PI3K) family of enzymes catalyzes the phosphorylation of the 3-hydroxyl group of the inositol ring of phosphatidylinositol. PI3Ks play an important role in a variety of fundamental cellular processes, including cell motility, the Ras pathway, vesicle trafficking and secretion, immune cell activation and apoptosis. They are also involved in the regulation of clathrin-mediated membrane trafficking as well as ATP-dependent priming of neurosecretory granule exocytosis. PI3Ks are divided into three main classes (I, II, and III) based on their substrate specificity, regulation, and domain structure. Class II PI3Ks preferentially use PI as a substrate to produce PI3P, but can also phosphorylate PI4P to produce PI(3,4)P2. They function as monomers and do not associate with any regulatory subunits. Class II enzymes contain an N-terminal Ras binding domain, a lipid binding C2 domain, a PI3K homology domain of unknown function, an ATP-binding cataytic domain, a PX domain, and a second C2 domain at the C-terminus. Class II PI3Ks include three vertebrate isoforms (alpha, beta, and gamma), the Drosophila PI3K_68D, and similar proteins.

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).

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.

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).

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.

RIM proteins and Gallus gallus protein piccolo (also called aczonin) are involved in neurotransmitter release at presynaptic active zones, the site of vesicle fusion. A protein complex containing RIM proteins positions synaptic vesicles containing synaptotagmin at the active zone. RIM proteins simultaneously activate docking and priming of synaptic vesicles and recruit Ca2+-channels to active zones, thereby connecting primed synaptic vesicles to Ca2+-channels. RIM binding to vesicular Rab proteins (Rab3 and Rab27 isoforms) mediates vesicle docking; RIM binding to Munc13 activates vesicle priming; RIM binding to the Ca2+-channel, both directly and indirectly via RIM-BP, recruits the Ca2+-channels. The RIM PDZ domain interacts with the C-termini of N- and P/Q-type voltage-gated Ca2+-channels. RIM1, RIM2 and piccolo also participate in regulated exocytosis through binding cAMP-GEFII (cAMP-binding protein-guanidine nucleotide exchange factor II). The piccolo PDZ domain binds cAMP-GEFII. RIM2 also plays a role in dendrite formation by melanocytes. Caenorhabditis elegans RIM (also known as unc-10) may be involved in the regulation of defecation and daumone response. 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).

RseP is involved in the regulation of an extracytoplasmic stress response through the cleavage of membrane-spanning anti-stress-response transcription factor (anti-sigmE) 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 its 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.

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.

 190-264 5.67e-06

The phosphoinositide binding Phox Homology Domain of the Gamma Isoform of Class II Phosphoinositide 3-Kinases; The PX domain is a phosphoinositide (PI) binding module present in many proteins with diverse functions. The Phosphoinositide 3-Kinase (PI3K) family of enzymes catalyzes the phosphorylation of the 3-hydroxyl group of the inositol ring of phosphatidylinositol. PI3Ks play an important role in a variety of fundamental cellular processes, including cell motility, the Ras pathway, vesicle trafficking and secretion, immune cell activation and apoptosis. PI3Ks are divided into three main classes (I, II, and III) based on their substrate specificity, regulation, and domain structure. Class II PI3Ks preferentially use PI as a substrate to produce PI3P, but can also phosphorylate PI4P to produce PI(3,4)P2. They function as monomers and do not associate with any regulatory subunits. Class II enzymes contain an N-terminal Ras binding domain, a lipid binding C2 domain, a PI3K homology domain of unknown function, an ATP-binding cataytic domain, a PX domain, and a second C2 domain at the C-terminus. The class II gamma isoform, PI3K-C2gamma, is expressed in the liver, breast, and prostate. It's biological function remains unknown. The PX domain is involved in targeting of proteins to PI-enriched membranes, and may also be involved in protein-protein interaction.

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).

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.

 173-262 1.15e-05

The phosphoinositide binding Phox Homology domain of Sorting Nexin 13; The PX domain is a phosphoinositide (PI) binding module present in many proteins with diverse functions. Sorting nexins (SNXs) make up the largest group among PX domain containing proteins. They are involved in regulating membrane traffic and protein sorting in the endosomal system. The PX domain of SNXs binds PIs and targets the protein to PI-enriched membranes. SNXs differ from each other in PI-binding specificity and affinity, and the presence of other protein-protein interaction domains, which help determine subcellular localization and specific function in the endocytic pathway. SNX13, also called RGS-PX1, contains an N-terminal PXA domain, a regulator of G protein signaling (RGS) domain, a PX domain, and a C-terminal domain that is conserved in some SNXs. It specifically binds to the stimulatory subunit of the heterotrimeric G protein G(alpha)s, serving as its GTPase activating protein, through the RGS domain. It preferentially binds phosphatidylinositol-3-phosphate (PI3P) through the PX domain and is localized in early endosomes. SNX13 is involved in endosomal sorting of EGFR into multivesicular bodies (MVB) for delivery to the lysosome.

SNX18, like SNX9, contains an N-terminal Src Homology 3 (SH3) domain, a PX domain, and a C-terminal Bin/Amphiphysin/Rvs (BAR) domain, which detects membrane curvature. The PX-BAR structural unit helps determine specific membrane localization. SNX18 is localized to peripheral endosomal structures, and acts in a trafficking pathway that is clathrin-independent but relies on AP-1 and PACS1.

The Rap-GTPase activating protein SIPA1 (also known as GTPase-activating protein Spa-1, p130 SPA1) is a metastasis promoter; a polymorphism in a region of the Sipa1 gene encoding the PDZ domain is associated with metastasis. The SIPA1 PDZ domain binds ribosomal RNA processing 1 homolog B (Rrp1b). SIPA1 also forms a complex with water channel aquaporin-2 (AQP2) and plays a role in trafficking of AQP2, targeted positioning of which strictly regulates body water homeostasis; the SIPA1 PDZ domain binds AQP2. Rrp1b or AQP2 binding inhibits the RapGAP activity of SIPA1. 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 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 3 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 Par-3 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.

PDZ domain 3 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 3 of the long isoform 1 of PDZD7, and related domains. PDZD7 is critical for the organization of the 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 and can also form homodimers through its PDZ2 domain. Various isoforms of PDZD7 produced by alternative splicing have been identified; this subgroup includes the third 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.

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).

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.

 81-126 4.32e-05

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 of Golgi-associated PDZ and coiled-coil motif-containing protein (GOPC), and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of GOPC and related domains. GOPC, also known as PIST (PDZ domain protein interacting specifically with TC10), FIG (fused in glioblastoma), and CAL (CFTR-associated ligand), regulates the trafficking of a wide array of proteins, including small GTPases, receptors, and cell surface molecules such as cadherin 23 and CFTR. It may regulate CFTR chloride currents and acid-sensing ASIC3 currents by modulating cell surface expression of both channels, and may play a role in autophagy. Interaction partners of the GOPC PDZ domains include: FZD5, FZD8, ASIC3, CFTR, MUC3, ARFRP1, Ggamma13, neuroligin, and Stargazin. 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 GOPC-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 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.

 171-262 9.27e-05

The phosphoinositide binding Phox Homology domain of Sorting Nexins 7 and 30; The PX domain is a phosphoinositide (PI) binding module present in many proteins with diverse functions. Sorting nexins (SNXs) make up the largest group among PX domain containing proteins. They are involved in regulating membrane traffic and protein sorting in the endosomal system. The PX domain of SNXs binds PIs and targets the protein to PI-enriched membranes. SNXs differ from each other in PI-binding specificity and affinity, and the presence of other protein-protein interaction domains, which help determine subcellular localization and specific function in the endocytic pathway. Some SNXs are localized in early endosome structures such as clathrin-coated pits, while others are located in late structures of the endocytic pathway. This subfamily consists of SNX7, SNX30, and similar proteins. They harbor a Bin/Amphiphysin/Rvs (BAR) domain, which detects membrane curvature, C-terminal to the PX domain, similar to the sorting nexins SNX1-2, SNX4-6, SNX8, and SNX32. Both domains have been shown to determine the specific membrane-targeting of SNX1. The specific function of the sorting nexins in this subfamily has yet to be elucidated.

 195-265 1.02e-04

The phosphoinositide binding Phox Homology domain of yeast Atg24p, an autophagic degradation protein; The PX domain is a phosphoinositide (PI) binding module present in many proteins with diverse functions. The yeast Atg24p is a sorting nexin (SNX) which is involved in membrane fusion events at the vacuolar surface during pexophagy. This is facilitated via binding of Atg24p to phosphatidylinositol 3-phosphate (PI3P) through its PX domain. SNXs make up the largest group among PX domain containing proteins. They are involved in regulating membrane traffic and protein sorting in the endosomal system. The PX domain of SNXs binds PIs and targets the protein to PI-enriched membranes. SNXs differ from each other in PI-binding specificity and affinity, and the presence of other protein-protein interaction domains, which help determine subcellular localization and specific function in the endocytic pathway.

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.

circularly permuted PDZ domain of Synechocystis sp. PCC 6803 putative serine proteases HhoA, HhoB, and HtrA and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of the cyanobacterial Synechocystis sp. PCC 6803 putative serine proteases HhoA, HhoB and HtrA, and related domains. These three proteases are functionally overlapping, and are involved in a number of key physiological responses, ranging from protection against light and heat stresses to phototaxis. HhoA assembles into trimers, mediated by its protease domain and further into a hexamer by a novel interaction between the PDZ domains of opposing trimers. 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 HhoA-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.

The Par complex comprises atypical protein kinase C (aPKC) and two scaffolding proteins, Par3 (Bazooka (Baz) in Drosophila) and Par6; bazooka (DmPar3) has three central PDZ domains. Both PDZ1 and PDZ3 domains, but not PDZ2, in bazooka (DmPar3) engage in a canonical interaction with the PDZ domain-binding motif in Par6. 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 bazooka-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.

 195-246 5.31e-04

The phosphoinositide binding Phox Homology domain of fungal Grd19; The PX domain is a phosphoinositide (PI) binding module present in many proteins with diverse functions. Sorting nexins (SNXs) make up the largest group among PX domain containing proteins. They are involved in regulating membrane traffic and protein sorting in the endosomal system. The PX domain of SNXs binds PIs and targets the protein to PI-enriched membranes. SNXs differ from each other in PI-binding specificity and affinity, and the presence of other protein-protein interaction domains, which help determine subcellular localization and specific function in the endocytic pathway. Grd19 is involved in the localization of late Golgi membrane proteins in yeast. Grp19 associates with the retromer complex, a membrane coat multimeric complex required for endosomal retrieval of lysosomal hydrolase receptors to the Golgi, and functions as a cargo-specific adaptor for the retromer.

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 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 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.

 196-267 1.11e-03

The phosphoinositide binding Phox Homology domain of Sorting Nexin 9; The PX domain is a phosphoinositide (PI) binding module present in many proteins with diverse functions. Sorting nexins (SNXs) make up the largest group among PX domain containing proteins. They are involved in regulating membrane traffic and protein sorting in the endosomal system. The PX domain of SNXs binds PIs and targets the protein to PI-enriched membranes. SNXs differ from each other in PI-binding specificity and affinity, and the presence of other protein-protein interaction domains, which help determine subcellular localization and specific function in the endocytic pathway. SNX9, also known as SH3PX1, is a cytosolic protein that interacts with proteins associated with clathrin-coated pits such as Cdc-42-associated tyrosine kinase 2 (ACK2). It contains an N-terminal Src Homology 3 (SH3) domain, a PX domain, and a C-terminal Bin/Amphiphysin/Rvs (BAR) domain, which detects membrane curvature. The PX-BAR structural unit helps determine specific membrane localization. Through its SH3 domain, SNX9 binds class I polyproline sequences found in dynamin 1/2 and the WASP/N-WASP actin regulators. SNX9 is localized to plasma membrane endocytic sites and acts primarily in clathrin-mediated endocytosis. Its array of interacting partners suggests that SNX9 functions at the interface between endocytosis and actin cytoskeletal organization.

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.

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. 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. 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 11 of MUPP1 of multi-PDZ-domain protein 1 (MUPP1), domain 9 of 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 11 of MUPP1, PDZ domain 9 of 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 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 MUPP1-like family PDZ11 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.

 262-344 2.19e-03

Ras-associating (RA) domain 1 found in Afadin; Afadin, also termed ALL1-fused gene from chromosome 6 protein (AF-6), or canoe, is involved in many fundamental signaling cascades in cells. In addition, it is involved in oncogenesis and metastasis. Afadin has multiple domains: from the N-terminus to the C-terminus it has two Ras-associated (RA) domains, a forkhead-associated domain, a dilute domain, a PDZ domain, three proline-rich domains, and an F-actin-binding domain. RA domain-containing proteins function by interacting with Ras proteins directly or indirectly and are involved in several different functions ranging from tumor suppression to being oncoproteins. Ras proteins are small GTPases that are involved in cellular signal transduction. The RA domain has a beta-grasp ubiquitin-like (Ubl) fold with low sequence similarity to ubiquitin (Ub). Ub is a protein modifier in eukaryotes that is involved in various cellular processes including transcriptional regulation, cell cycle control, and DNA repair in eukaryotes. Afadin is abundant at cadherin-based adherens junctions in epithelial cells, endothelial cells, and fibroblasts. This family corresponds to the first RA domain of afadin, which mediates its self-association.

The phosphoinositide binding Phox Homology domain of Sorting Nexin 25; The PX domain is a phosphoinositide (PI) binding module present in many proteins with diverse functions. Sorting nexins (SNXs) make up the largest group among PX domain containing proteins. They are involved in regulating membrane traffic and protein sorting in the endosomal system. The PX domain of SNXs binds PIs and targets the protein to PI-enriched membranes. SNXs differ from each other in PI-binding specificity and affinity, and the presence of other protein-protein interaction domains, which help determine subcellular localization and specific function in the endocytic pathway. The function of SNX25 is not yet known. It has been found in exosomes from human malignant pleural effusions. SNX25 shows the same domain architecture as SNX13 and SNX14, containing an N-terminal PXA domain, a regulator of G protein signaling (RGS) domain, a PX domain, and a C-terminal domain that is conserved in some SNXs.

PDZ domain 3 of the full-length isoform of whirlin, PDZ domain 1 of the short isoform of whirlin, and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 3 of the full-length isoform of whirlin, PDZ domain 1 of the short 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 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

The PX domain of SNXs binds PIs and targets the protein to PI-enriched membranes. SNXs differ from each other in PI-binding specificity and affinity, and the presence of other protein-protein interaction domains, which help determine subcellular localization and specific function in the endocytic pathway. SNX4 is involved in recycling traffic from the sorting endosome (post-Golgi endosome) back to the late Golgi. It shows a similar domain architecture as SNX1-2, among others, containing a Bin/Amphiphysin/Rvs (BAR) domain, which detects membrane curvature, C-terminal to the PX domain. SNX4 is implicated in the regulation of plasma membrane receptor trafficking and interacts with receptors for EGF, insulin, platelet-derived growth factor and the long form of the leptin receptor.

Both domains have been shown to determine the specific membrane-targeting of SNX1. SNX1 and SNX2 are components of the retromer complex, a membrane coat multimeric complex required for endosomal retrieval of lysosomal hydrolase receptors to the Golgi. The retromer consists of a cargo-recognition subcomplex and a subcomplex formed by a dimer of sorting nexins (SNX1 and/or SNX2), which ensures effcient cargo sorting by facilitating proper membrane localization of the cargo-recognition subcomplex.

 175-269 3.08e-03

The phosphoinositide binding Phox Homology domain of the p40phox subunit of NADPH oxidase; The PX domain is a phosphoinositide binding module present in many proteins with diverse functions such as cell signaling, vesicular trafficking, protein sorting, and lipid modification, among others. p40phox contains an N-terminal PX domain, a central SH3 domain that binds p47phox, and a C-terminal PB1 domain that interacts with p67phox. It is a cytosolic subunit of the phagocytic NADPH oxidase complex (also called Nox2 or gp91phox) which plays a crucial role in the cellular response to bacterial infection. NADPH oxidase catalyzes the transfer of electrons from NADPH to oxygen during phagocytosis forming superoxide and reactive oxygen species. p40phox positively regulates NADPH oxidase in both phosphatidylinositol-3-phosphate (PI3P)-dependent and PI3P-independent manner. The PX domain is a phospholipid-binding module involved in the membrane targeting of proteins. The p40phox PX domain binds to PI3P, an abundant lipid in phagosomal membranes, playing an important role in the localization of NADPH oxidase. The PX domain of p40phox is also involved in protein-protein interaction.

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.

PDZ domain of connector enhancer of kinase suppressor of ras 1 (CNK1), CNK2, CNK3, and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of CNK1 (also known as connector enhancer of KSR 1 (CNKSR1), CNK homolog protein 1, connector enhancer of KSR-like), CNK2 (also known as CNKSR2, CNK homolog protein 2), and CNK3 (also known as CNKSR3, CNK homolog protein 3, CNKSR family member 3, maguin-like). CNK proteins modulate Ras-mediated signaling, acting downstream of Ras as a scaffold for the Raf/MEK/ERK kinase cascade. They also modulate signaling mediated via Rho family small GTPases, through interactions with various guanine nucleotide exchange factors (GEFs) and GTPase activating proteins (GAPs), and modulate the insulin signaling pathway through interactions with the Arf guanine nucleotide exchange factors. CNK proteins also regulate cell proliferation and migration by acting as scaffolds for the PI3K/Akt and JNK signaling cascades. CNK2 plays a role in the molecular processes that govern morphology of the postsynaptic density (PSD), and influences subcellular localization of the regulatory NCK-interacting kinase TNIK. TNIK binds a region of CNK2 including the PDZ and the DUF domain; this region also binds the kinase MINK1. CNK2 may also influence the membrane localization of MINK1. CNK3 plays a part in transepithelial sodium transport; it coordinates assembly of an epithelial sodium channel (ENaC)-regulatory 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 CNK1-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 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.

 166-248 5.19e-03

The phosphoinositide binding Phox Homology Domain of Cytokine-Independent Survival Kinase; The PX domain is a phosphoinositide (PI) binding module present in many proteins with diverse functions. Cytokine-independent survival kinase (CISK), also called Serum- and Glucocorticoid-induced Kinase 3 (SGK3), plays a role in cell growth and survival. It is expressed in most tissues and is most abundant in the embryo and adult heart and spleen. It was originally discovered in a screen for antiapoptotic genes. It phosphorylates and inhibits the proapoptotic proteins, Bad and FKHRL1. CISK/SGK3 also regulates many transporters, ion channels, and receptors. It plays a critical role in hair follicle morphogenesis and hair cycling. N-terminal to a catalytic kinase domain, CISK contains a PX domain which binds highly phosphorylated PIs, directs membrane localization, and regulates the enzyme's activity.

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.

 277-345 5.60e-03

Ras-associating (RA) domain found in Saccharomyces cerevisiae adenylate cyclase and similar proteins; CYR1, also termed ATP pyrophosphate-lyase, or adenylyl cyclase, is a fungal adenylate cyclase that regulates developmental processes such as hyphal growth, biofilm formation, and phenotypic switching. CYR1 plays essential roles in regulation of cellular metabolism by catalyzing the synthesis of a second messenger, cAMP. It acts as a scaffold protein keeping Ras2 available for its regulatory factors, the Ira proteins. CYR1 has at least four domains, including an N-terminal adenylate cyclase G-alpha binding domain, a Ras-associating (RA) domain, a middle leucine-rich repeat region, and a catalytic domain. The RA domain has the beta-grasp ubiquitin-like fold with low sequence similarity to ubiquitin; ubiquitin is a protein modifier in eukaryotes that is involved in various cellular processes including transcriptional regulation, cell cycle control, and DNA repair. The RA domain of CYR1 post-translationally modifies a small GTPase called Ras, which is involved in cellular signal transduction. CYR1 activity is stimulated directly by regulatory proteins (Ras1 and Gpa2), peptidoglycan fragments and carbon dioxide.

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).

 273-322 7.49e-03

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in unconventional myosin-X and similar proteins; Myosin-X, also termed myosin-10 (Myo10), is an untraditional member of myosin superfamily. It is an actin-based motor protein that plays a critical role in diverse cellular motile events, such as filopodia formation/extension, phagocytosis, cell migration, and mitotic spindle maintenance, as well as a number of disease states including cancer metastasis and pathogen infection. Myosin-X functions as an important regulator of cytoskeleton that modulates cell motilities in many different cellular contexts. It regulates neuronal radial migration through interacting with N-cadherin. Like other unconventional myosins, Myosin-X is composed of a conserved motor head, a neck region and a variable tail. The neck region consists of three IQ motifs (light chain-binding sites), and a predicted stalk of coiled coil. The tail contains three PEST regions, three PH domains, a MyTH4 domain, and a FERM domain. The FERM domain is made up of three sub-domains, F1, F2, and F3. This family corresponds to the F1 sub-domain, which is also called the N-terminal ubiquitin-like structural domain of the FERM domain (FERM_N). Amoebozoan Dictyostelium discoideum myosin VII (DdMyo7) and uncharacterized pleckstrin homology domain-containing family H member 3 (PLEKHH3) are also included in this family. Like metazoan Myo10, DdMyo7 is essential for the extension of filopodia, plasma membrane protrusions filled with parallel bundles of F-actin.

The LIMK family is composed of LIMK1 and LIMK2, which are common downstream effectors of several signalization pathways and function as signaling nodes that control cytoskeleton dynamics through the phosphorylation of cofilin family proteins. They also control microtubule dynamics. The LIMK1 PDZ domain binds tubulin and nischarin. LIMK1 also binds a carboxy-terminal motif of membrane type 1-matrix metalloproteinase (MT1-MMP, also known as MMP14) having features of a PDZ domain-binding site; MT1-MMP is a major protease involved in dissemination of carcinoma cells during cancer progression.
