Gene name

RASA2

Description

RAS p21 protein activator 2

Protein class

Mapped to UniProt SWISS-PROT, Potential transmembrane proteins, Potentially secreted proteins

Protein evidence

High

Entrez gene summary

The protein encoded by this gene is member of the GAP1 family of GTPase-activating proteins. The gene product stimulates the GTPase activity of normal RAS p21 but not its oncogenic counterpart. Acting as a suppressor of RAS function, the protein 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. This particular family member has a perinuclear localization and is an inositol 1,3,4,5-tetrakisphosphate-binding protein; a compound suggested to function as a second messenger.

Staining summary

A subset of alveolar cells and hepatocytes showed strong cytoplasmic staining. Glandular cells of gastrointestinal tract, male and female reproductive tracts, gall bladder and most squamous cells were moderately stained. Remaining normal cells were in general weakly stained or negative.
