DESCRIPTION

Also known as PRAG1_HUMAN, PRAG1, SGK223. Catalytically inactive protein kinase that acts as a scaffold protein. Functions as an effector of the small GTPase RND2, which stimulates RhoA activity and inhibits NGF-induced neurite outgrowth (By similarity). Promotes Src family kinase (SFK) signaling by regulating the subcellular localization of CSK, a negative regulator of these kinases, leading to the regulation of cell morphology and motility by a CSK-dependent mechanism (By similarity). Acts as a critical coactivator of Notch signaling (By similarity). Homodimer (PubMed:29079850). Dimerization leads to the catalytic activation of CSK (By similarity). Interacts (via C-terminus) with RND2 (By similarity). Interacts with CSK (via SH2 domain) in a Tyr-413 phosphorylation-dependent manner; this interaction potentiates kinase activity of CSK (By similarity). Interacts with PEAK1 (PubMed:29079850). Interacts with NOTCH1 intracellular domain (N1ICD) (By similarity). Forms a complex with N1ICD and MAML1, in a MAML1-dependent manner (By similarity).
