RASA1 (human)

Overview
RASA1 a GTPase activator for normal RAS p21 but not its oncogenic counterpart, converting it to the putatively inactive GDP-bound state. Acting as a suppressor of RAS function, it enhances the weak intrinsic GTPase activity of RAS proteins resulting in the inactive GDP-bound form of RAS, thereby allowing control of cellular proliferation and differentiation. Mutations leading to changes in the binding sites of either protein are associated with basal cell carcinomas. Two alternatively spliced isoforms have been described. Note: This description may include information from UniProtKB.
