UniProt Protein Function: | RASAL1: a GTPase activating protein for Ras. Negatively regulates Ras (H-Ras) signaling activity. Two alternatively-spliced isoforms have been described. PITX1 inhibits tumorigenicity of the Ras pathway by inducing the transcription of RASAL1, which in turn inactivates Ras. Two alternatively-spliced isoforms have been described. |
UniProt Protein Details: | Protein type:GAPs, Ras; GAPs Chromosomal Location of Human Ortholog: 12q23-q24 Cellular Component: cytosol; plasma membrane Molecular Function:phospholipid binding Biological Process: MAPKKK cascade; negative regulation of Ras protein signal transduction; signal transduction |
NCBI Summary: | The protein encoded by this gene is member of the GAP1 family of GTPase-activating proteins. These proteins stimulate 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 contains domains which are characteristic of the GAP1 subfamily of RasGAP proteins but, in contrast to the other GAP1 family members, this protein is strongly and selectively expressed in endocrine tissues. Alternatively spliced transcript variants that encode different isoforms have been described [provided by RefSeq, Jul 2010] |
