210-316 9.57e-67

Actin filament associated protein family Pleckstrin homology (PH) domain, repeat 1; There are 3 members of the AFAP family of adaptor proteins: AFAP1, AFAP1L1, and AFAP1L2/XB130. AFAP1 is a cSrc binding partner and actin cross-linking protein. AFAP1L1 is thought to play a similar role to AFAP1 in terms of being an actin cross-linking protein, but it preferentially binds to cortactin and not cSrc, thereby playing a role in invadosome formation. AFAP1L2 is a cSrc binding protein, but does not bind to actin filaments. AFAP1L2 acts as an intermediary between the RET/PTC kinase and PI-3kinase pathway in the thyroid. The AFAPs share a similar structure of a SH3 binding motif, 3 SH2 binding motifs, 2 PH domains, a coiled-coil region corresponding to the AFAP1 leucine zipper, and an actin binding domain. The amino terminal PH1 domain of AFAP1 has been known to function in intra-molecular regulation of AFAP1. In addition, the PH1 domain is a binding partner for PKCa and phospholipids. This cd is the first PH domain of AFAP. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

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

224-319 9.36e-05

Src kinase-associated phosphoprotein family Pleckstrin homology (PH) domain; Skap adaptor proteins couple receptors to cytoskeletal rearrangements. Src kinase-associated phosphoprotein of 55 kDa (Skap55)/Src kinase-associated phosphoprotein 1 (Skap1), Skap2, and Skap-homology (Skap-hom) have an N-terminal coiled-coil conformation, a central PH domain and a C-terminal SH3 domain. Their PH domains bind 3'-phosphoinositides as well as directly affecting targets such as in Skap55 where it directly affecting integrin regulation by ADAP and NF-kappaB activation or in Skap-hom where the dimerization and PH domains comprise a 3'-phosphoinositide-gated molecular switch that controls ruffle formation. PH domains are only found in eukaryotes. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized.

Actin filament associated protein family Pleckstrin homology (PH) domain, repeat 2; There are 3 members of the AFAP family of adaptor proteins: AFAP1, AFAP1L1, and AFAP1L2/XB130. AFAP1 is a cSrc binding partner and actin cross-linking protein. AFAP1L1 is thought to play a similar role to AFAP1 in terms of being an actin cross-linking protein, but it preferentially binds to cortactin and not cSrc, thereby playing a role in invadosome formation. AFAP1L2 is a cSrc binding protein, but does not bind to actin filaments. AFAP1L2 acts as an intermediary between the RET/PTC kinase and PI-3kinase pathway in the thyroid. The AFAPs share a similar structure of a SH3 binding motif, 3 SH2 binding motifs, 2 PH domains, a coiled-coil region corresponding to the AFAP1 leucine zipper, and an actin binding domain. This cd is the second PH domain of AFAP. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

228-320 7.23e-04

Rho GTPase activating protein 2 Pleckstrin homology (PH) domain; RhoGAP2 (also called RhoGap22 or ArhGap22) are involved in cell polarity, cell morphology and cytoskeletal organization. They activate a GTPase belonging to the RAS superfamily of small GTP-binding proteins. The encoded protein is insulin-responsive, is dependent on the kinase Akt, and requires the Akt-dependent 14-3-3 binding protein which binds sequentially to two serine residues resulting in regulation of cell motility. Members here contain an N-terminal PH domain followed by a RhoGAP domain and either a BAR or TATA Binding Protein (TBP) Associated Factor 4 (TAF4) domain. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

Pleckstrin homology (PH) domain containing, family D (with coiled-coil domains) member 1 PH domain; Human PLEKHD1 (also called UPF0639, pleckstrin homology domain containing, family D (with M protein repeats) member 1) is a single transcript and contains a single PH domain. PLEKHD1 is conserved in human, chimpanzee, , dog, cow, mouse, chicken, zebrafish, and Caenorhabditis elegans. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized.

226-323 6.07e-03

Pleckstrin 2 Pleckstrin homology (PH) domain, repeat 1; Pleckstrin is a protein found in platelets. This name is derived from platelet and leukocyte C kinase substrate and the KSTR string of amino acids. Pleckstrin 2 contains two PH domains and a DEP (dishvelled, egl-10, and pleckstrin) domain. Unlike pleckstrin 1, pleckstrin 2 does not contain obvious sites of PKC phosphorylation. Pleckstrin 2 plays a role in actin rearrangement, large lamellipodia and peripheral ruffle formation, and may help orchestrate cytoskeletal arrangement. The PH domains of pleckstrin 2 are thought to contribute to lamellipodia formation. This cd contains the first PH domain repeat. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity.
