Pleckstrin homology-like domain; The PH-like family includes the PH domain, both the Shc-like and IRS-like PTB domains, the ran-binding domain, the EVH1 domain, a domain in neurobeachin and the third domain of FERM. All of these domains have a PH fold, but lack significant sequence similarity. They are generally involved in targeting to protein to the appropriate cellular location or interacting with a binding partner. This domain family possesses multiple functions including the ability to bind inositol phosphates and to other proteins.

Pleckstrin homology domain containing family N member 1Pleckstrin homology-like domain; Not much is known about PLEKHN1. It is found in a wide range of animals including humans, green anole, frog, and zebrafish. It contains 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.

Cloned out of library/PAK-interactive exchange factor pleckstrin homology (PH) domain; There are two forms of Pix proteins: alpha Pix (also called Rho guanine nucleotide exchange factor (GEF) 6/90Cool-2) and beta Pix (GEF7/p85Cool-1). betaPix contains an N-terminal SH3 domain, a RhoGEF/DH domain, a PH domain, a GIT1 binding domain (GBD), and a C-terminal coiled-coil (CC) domain. alphaPix differs in that it contains a calponin homology (CH) domain, which interacts with beta-parvin, N-terminal to the SH3 domain. alphaPix is an exchange factor for Rac1 and Cdc42 and mediates Pak activation on cell adhesion to fibronectin. Mutations in alphaPix can cause X-linked mental retardation. alphaPix also interacts with Huntington's disease protein (htt), and enhances the aggregation of mutant htt (muthtt) by facilitating SDS-soluble muthtt-muthtt interactions. The DH-PH domain of a Pix was required for its binding to htt. In the majority of Rho GEF proteins, the DH-PH domain is responsible for the exchange activity. 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.
