This entry represents a pleckstrin homology (PH) domain found in MRCK (myotonic dystrophy kinase-related Cdc42-binding kinase) proteins that forms part of a tripartite C1-PH-CNH regulatory module. The PH domain is distinguished by a loop insertion between strands beta6 and beta7 that packs against the CNH domain. The domain contains conserved basic residues in the beta1-beta2 loop that may be involved in membrane binding. This PH domain shows weak binding to phosphoinositides with a preference for di-phosphorylated PIPs. The domain architecture of MRCK proteins includes an N-terminal kinase domain, a coiled-coil region, and C-terminal C1, PH and CNH domains arranged in a tripartite module that helps localize the protein to membranes.
