contains two PH domains. ARAP proteins contain five PH domains. Serine/threonine-specific protein kinases such as the Akt/Rac family, protein kinase D1, and the trypanosomal NrkA family. Non-receptor tyrosine kinases belonging to the Btk/Itk/Tec subfamily. Insulin receptor substrate 1 (IRS-1). Regulators of small G-proteins: 64 RhoGEFs of the Dbl-like family., and several GTPase activating proteins like ABR, BCR or ARAP proteins. Cytoskeletal proteins such as dynamin (see ), Caenorhabditis elegans kinesin-like protein unc-104 (see ), spectrin beta-chain, syntrophin (2 PH domains), and S. cerevisiae nuclear migration protein NUM1. Oxysterol-binding proteins OSBP, S. cerevisiae OSH1 and YHR073w. Ceramide kinase, a lipid kinase that phosphorylates ceramides to ceramide-1-phosphate. G protein receptor kinases (GRK) of GRK2 subfamily (beta-adrenergic receptor kinases): GRK2 and GRK3.
