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. The actual alignment was detected with superfamily member cd14682: Pssm-ID: 473070 Cd Length: 118 Bit Score: 136.47 E-value: 8.24e-43

PH-like domain of Exocyst complex component 1-like; Exocyst complex component 1-like proteins are short, higher eukaryotic proteins that show homology to the PH-domain of higher eukaryotic EXOC1 and yeast SEC3 which are part of the exocyst complex involved in the docking of post-Golgi transport vesicles to sites of membrane remodeling during cellular processes such as polarization, migration, and division. Their function is unknown. 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.

Exocyst complex component SEC3 N-terminal PIP2 binding PH; This is the N-terminal domain of fungal and eukaryotic Sec3 proteins. Sec3 is a component of the exocyst complex that is involved in the docking of exocytic vesicles with fusion sites on the plasma membrane.This N-terminal domain contains a cryptic pleckstrin homology (PH) fold, and all six positively charged lysine and arginine residues in the PH domain predicted to bind the PIP2 head group are conserved. The exocyst complex is essential for many exocytic events, by tethering vesicles at the plasma membrane for fusion. In fission yeast, polarised exocytosis for growth relies on the combined action of the exocyst at cell poles and myosin-driven transport along actin cables.
