Neuroepithelial cell transforming 1 Pleckstrin homology (PH) domain; Net1 (also called ArhGEF8) is part of the family of Rho guanine nucleotide exchange factors. Members of this family activate Rho proteins by catalyzing the exchange of GDP for GTP. The protein encoded by this gene interacts with RhoA within the cell nucleus and may play a role in repairing DNA damage after ionizing radiation. Net1 binds to caspase activation and recruitment domain (CARD)- and membrane-associated guanylate kinase-like domain-containing (CARMA) proteins and regulates nuclear factor kB activation. Net1 contains a RhoGEF domain N-terminal to a single PH 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 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.

Intersectin Pleckstrin homology (PH) domain; ITSNs, an adaptor protein family, play a role in endo- and exocytosis, actin cytoskeleton rearrangement and signal transduction. There are two human ITSN genes: ITSN1 and ITSN2. They share significant sequence identity and a similar domain structure having both short and long isoforms produced by alternative splicing. The short isoform (ITSN-S) consists of two Eps15 homology domains (EH1 and EH2), a coiled-coil region (CCR) and five Src homology 3 domains (SH3A-E). The EH domains bind to Asn-Pro-Phe motifs and are implicated in endocytosis and vesicle transport. The SH3 domains bind to proline-rich sequences and are commonly found in proteins implicated in cell signalling pathways, cytoskeletal organization and membrane traffic. The long isoform (ITSN-L) contains three additional C-terminal domains, a Dbl homology domain (DH), a Pleckstrin homology domain (PH) and a C2 domain. The tandem DH-PH domains are present in all Dbl family of GEFs. ITSN acts specifically on Cdc42 through its DH domain with no portion of the PH domain making contact with Cdc42. This is in contrast to Dbs which requires the PH domain for full catalytic activity. The ITSN PH domain binds phosphoinositides. C2 domains are usually involved in Ca2+-dependent and Ca2+-independent phospholipid binding. There are more than 30 proteins that interact with ITSNs. ITSN-S is present in mammals, frogs, flies and nematodes, while ITSN-L is present only in vertebrates. 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.

p63RhoGEF pleckstrin homology (PH) domain, repeat 2; The guanine nucleotide exchange factor p63RhoGEF is an effector of the heterotrimeric G protein, Galphaq and linking Galphaq-coupled receptors (GPCRs) to the activation of RhoA. The Dbl(DH) and PH domains of p63RhoGEF interact with the effector-binding site and the C-terminal region of Galphaq and appear to relieve autoinhibition of the catalytic DH domain by the PH domain. Trio, Duet, and p63RhoGEF are shown to constitute a family of Galphaq effectors that appear to activate RhoA both in vitro and in intact cells. Dbs is a guanine nucleotide exchange factor (GEF), which contains spectrin repeats, a rhoGEF (DH) domain and a PH domain. The Dbs PH domain participates in binding to both the Cdc42 and RhoA GTPases. Trio plays an essential role in regulating the actin cytoskeleton during axonal guidance and branching. Trio is a multidomain signaling protein that contains two RhoGEF(DH)-PH domains in tandem. 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-containing family G member 7 pleckstrin homology (PH) domain; PLEKHG7 has a RhoGEF DH/double-homology domain in tandem with a PH domain which is involved in phospholipid binding. PLEKHG7 is proposed to functions as a guanine nucleotide exchange factor (GEF) and is involved in the regulation of Rho protein signal transduction. 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.
