RASAL2 (Ras protein activator like 2), also known as nGAP, is a Ras GTPase-activating protein. RAS proteins cycle between an active guanosine-triphosphate (GTP) bound form and an inactive, guanosine-diphosphate (GDP) bound form. GTPase-activating proteins (GAPs) accelerate the intrinsic rate of GTP hydrolysis of Ras-related proteins, resulting in downregulation of their active form. RASAL2 functions in the Ras/MAPK/ERK signaling pathway. It contains a C2 domain, a PH domain and a Ras-GAP domain. The gene encoding RASAL2 is located on chromosome 1 within the prostate cancer susceptibility locus. This suggests that a mutation or defect in RASAL2 is implicated in carcinogenesis. Two transcript variants exist for RASAL2 due to alternative splicing events. |
