Exchange Factor for ARF6 Pleckstrin homology (PH) domain; EFA6 (also called PSD/pleckstrin and Sec7 domain containing) is an guanine nucleotide exchange factor for ADP ribosylation factor 6 (ARF6), which is involved in membrane recycling. EFA6 has four structurally related polypeptides: EFA6A, EFA6B, EFA6C and EFA6D. It consists of a N-terminal proline rich region (PR), a SEC7 domain, a PH domain, a PR, a coiled-coil region, and a C-terminal PR. The EFA6 PH domain regulates its association with the plasma membrane. EFA6 activates Arf6 through its Sec7 catalytic domain and modulates this activity through its C-terminal domain, which rearranges the actin cytoskeleton in fibroblastic cell lines. 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. : Pssm-ID: 270107 Cd Length: 126 Bit Score: 215.66 E-value: 2.25e-65

ARHGAP21 and related proteins pleckstrin homology (PH) domain; ARHGAP family genes encode Rho/Rac/Cdc42-like GTPase activating proteins with a RhoGAP domain. These proteins functions as a GTPase-activating protein (GAP) for RHOA and CDC42. ARHGAP21 controls the Arp2/3 complex and F-actin dynamics at the Golgi complex by regulating the activity of the small GTPase Cdc42. It is recruited to the Golgi by to GTPase, ARF1, through its PH domain and its helical motif. It is also required for CTNNA1 recruitment to adherens junctions. ARHGAP21 and it related proteins all contains a PH domain and a RhoGAP domain. Some of the members have additional N-terminal domains including PDZ, SH3, and SPEC. The ARHGAP21 PH domain interacts with the GTPbound forms of both ARF1 and ARF6 ARF-binding domain/ArfBD. The members here include: ARHGAP15, ARHGAP21, and ARHGAP23.

T-lymphoma invasion and metastasis 1 and 2 Pleckstrin Homology (PH) domain, N-terminal domain; Tiam1 activates Rac GTPases to induce membrane ruffling and cell motility while Tiam2 (also called STEF (SIF (still life) and Tiam1 like-exchange factor) contributes to neurite growth. Tiam1/2 are Dbl-family of GEFs that possess a Dbl(DH) domain with a PH domain in tandem. DH-PH domain catalyzes the GDP/GTP exchange reaction in the GTPase cycle and facillitating the switch between inactive GDP-bound and active GTP-bound states. Tiam1/2 possess two PH domains, which are often referred to as PHn and PHc domains. The DH-PH tandem domain is made up of the PHc domain while the PHn is part of a novel N-terminal PHCCEx domain which is made up of the PHn domain, a coiled coil region(CC), and an extra region (Ex). PHCCEx mediates binding to plasma membranes and signalling proteins in the activation of Rac GTPases. The PH domain resembles the beta-spectrin PH domain, suggesting non-canonical phosphatidylinositol binding. CC and Ex form a positively charged surface for protein binding. There are 2 motifs in Tiam1/2-interacting proteins that bind to the PHCCEx domain: Motif-I in CD44, ephrinBs, and the NMDA receptor and Motif-II in Par3 and JIP2.Neither of these fall in the PHn 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.

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.

Connector enhancer of KSR (Kinase suppressor of ras) (CNK) pleckstrin homology (PH) domain; CNK family members function as protein scaffolds, regulating the activity and the subcellular localization of RAS activated RAF. There is a single CNK protein present in Drosophila and Caenorhabditis elegans in contrast to mammals which have 3 CNK proteins (CNK1, CNK2, and CNK3). All of the CNK members contain a sterile a motif (SAM), a conserved region in CNK (CRIC) domain, and a PSD-95/DLG-1/ZO-1 (PDZ) domain, and, with the exception of CNK3, a PH domain. A CNK2 splice variant CNK2A also has a PDZ domain-binding motif at its C terminus and Drosophila CNK (D-CNK) also has a domain known as the Raf-interacting region (RIR) that mediates binding of the Drosophila Raf kinase. This cd contains CNKs from mammals, chickens, amphibians, fish, and crustacea. 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.
