PH domain of plant-specific actin-binding protein; This family is a PH domain found on plant-specific actin-binding proteins or SCABs. SCAB proteins bind, bundle and stabilize actin filaments and regulate stomatal movement. The Ig-PH fusion domain is at the C-terminus. This domain adopts the PH fold, of seven beta-strands, beta7-beta13 and two alpha-helices, alpha1 and alpha2 arranged into a beta-barrel. The canonical phosphoinositide-binding pocket of the classic PH domain is degenerate in this fused one, and the charge on the pocket suggest that the Ig-PH domain contains a non-canonical binding site for inositol phosphates.

Stomatal Closure Related Actin-Binding Protein 1 Pleckstrin homology-like domain; SCAB1 is an actin-binding protein that interacts with actin filaments and regulates stomatal movement. SCAB1 is composed of an actin-binding domain, two coiled-coil (CC) domains, and a fused immunoglobulin (Ig) and PH (Ig-PH) domain. SCAB1 homologs are widely present, often in multiple copies (three in Arabidopsis), in plants including eudicots, monocots, ferns and mosses, but are not found in algae and non-plant species. The C-terminal PH domain binds weakly with inositol phosphates via an atypical basic surface patch. SCAB1 forms a dimeric structure via its coiled-coil domains. 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.
