PDZ domain of PDZ domain-containing protein GIPC2, and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of GIPC2, and related domains. GIPC2 belongs to the GIPC family, members of which contain an N-terminal GIPC-homology 1 (GH1) domain, a central PDZ domain, and a C-terminal GH2 domain. GIPC proteins function as adaptor molecules that assemble RTKs, GPCRs, integrins, transmembrane proteins and cytoplasmic signaling regulators as cargoes of MYO6-dependent endocytic transport. Mutations in the Gipc2 gene have been linked to cancer. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This GIPC2 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.

GIPC-homology 2 (GH2) domain found in the GIPC family; The GIPC family includes PDZ domain-containing proteins, GIPC1 (also called GAIP C-terminus-interacting protein, RGS-GAIP-interacting protein, RGS19-interacting protein 1, RGS19IP1, synectin, tax interaction protein 2, or TIP-2), GIPC2, and GIPC3, which may act as scaffold proteins linking heterotrimeric G-proteins to seven-transmembrane-type WNT receptor or to receptor tyrosine kinases. They might play key roles in carcinogenesis and embryogenesis through modulation of growth factor signaling and cell adhesion. GIPCs are proteins with a GIPC homology 1 (GH1) domain, a central PDZ domain and a GH2 domain. This model corresponds to the GH2 domain, which mediates the interaction with myosin VI and is involved in homodimerization in the autoinhibited state.

153-215 1.73e-17

GIPC homology 2 (GH2) domain-like family; The GIPC (GAIP C-terminus-interacting protein) family of proteins mediate endocytosis by tethering cargo proteins to the motor myosin VI. This model represents the C-terminal GIPC homology 2 or GH2 domain (plus the linker to the PDZ domain located N-terminally of GH2), which mediates the interaction with myosin VI and is involved in homodimerization in the autoinhibited state. The family also includes DEAH box protein 8 (DHX8) and similar proteins. DHX8 (a human homolog of yeast Prp22), also called RNA helicase HRH1, is an ATP-dependent RNA helicase involved in pre-mRNA splicing as a component of the spliceosome. It facilitates nuclear export of spliced mRNA by releasing the RNA from the spliceosome. DHX8 contains a GH2-like domain at the N-terminus, which shows high sequence similarity with the GH2 domain found in GIPC proteins.

canonical PDZ domain; Canonical PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain. PDZ domains usually bind to short specific peptide sequences located at the C-terminal end of their partner proteins known as PDZ binding motifs. These domains can also interact with internal peptide motifs and certain lipids, and can take part in a head-to-tail oligomerization with other PDZ domains. The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. The canonical PDZ domain contains 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.

30-83 3.15e-05

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.

25-87 5.17e-03

PDZ domain 4 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 4 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 PDZ4 domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2); arranged as beta-strands A, -B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F.

31-78 7.44e-03

PDZ domain of peripheral plasma membrane protein CASK, Caenorhabditis Lin-2, and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of CASK, Caenorhabditis elegans Lin-2, and related domains. CASK and Lin-2 are membrane-associated guanylate kinase (MAGUK)-like proteins. CASK (also known as Calcium/calmodulin-dependent protein kinase, CAKI, and Camguk) has a role in synaptic transmembrane protein anchoring and ion channel trafficking. CASK may regulate transmembrane proteins that bind calcium, calmodulin, or nucleotides; it regulates the Drosophila ether a go-go (eag) potassium channel, and also regulates autophosphorylation of CaMKII. CASK binding partners include the transcription factor TBR1, and cell-surface proteins, including amyloid precursor protein, neurexins, and syndecans. Lin-2, as a component of the CLin-10-Lin-2-Lin-7 complex, plays a role in controlling the basolateral localization of the EGF receptor Let-23; this complex also associates with the neuron-specific motor protein KIF17 to transport vesicles containing N-methyl-D-aspartate (NMDA) receptor 2B along microtubules. CASK may also function in targeting or scaffolding of the protein parkin which is selectively truncated by a Parkinson's disease-causing mutation; the C-terminus of parkin functions as a class II PDZ-binding motif that binds CASK. 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 MPP6-MPP2-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.
