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.

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.

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 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 insects, spiders, mollusks, and nematodes. 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.

Rho GTPase activating protein 25 and related proteins Pleckstrin homology (PH) domain; RhoGAP25 (also called ArhGap25) like other RhoGaps are involved in cell polarity, cell morphology and cytoskeletal organization. They act as GTPase activators for the Rac-type GTPases by converting them to an inactive GDP-bound state and control actin remodeling by inactivating Rac downstream of Rho leading to suppress leading edge protrusion and promotes cell retraction to achieve cellular polarity and are able to suppress RAC1 and CDC42 activity in vitro. Overexpression of these proteins induces cell rounding with partial or complete disruption of actin stress fibers and formation of membrane ruffles, lamellipodia, and filopodia. This hierarchy contains RhoGAP22, RhoGAP24, and RhoGAP25. 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.

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.

TBC1 domain family member 2A pleckstrin homology (PH) domain; TBC1D2A (also called PARIS-1/Prostate antigen recognized and identified by SEREX 1 and ARMUS) contains a PH domain and a TBC-type GTPase catalytic domain. TBC1D2A integrates signaling between Arf6, Rac1, and Rab7 during junction disassembly. Activated Rac1 recruits TBC1D2A to locally inactivate Rab7 via its C-terminal TBC/RabGAP domain and facilitate E-cadherin degradation in lysosomes. The TBC1D2A PH domain mediates localization at cell-cell contacts and coprecipitates with cadherin complexes. 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.
