Previous GeneCards Identifiers for RASA4 Gene
This gene encodes a member of the GAP1 family of GTPase-activating proteins that suppresses the Ras/mitogen-activated protein kinase pathway in response to Ca(2+). Stimuli that increase intracellular Ca(2+) levels result in the translocation of this protein to the plasma membrane, where it activates Ras GTPase activity. Consequently, Ras is converted from the active GTP-bound state to the inactive GDP-bound state and no longer activates downstream pathways that regulate gene expression, cell growth, and differentiation. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]
GeneCards Summary for RASA4 Gene
RASA4 (RAS P21 Protein Activator 4) is a Protein Coding gene. Among its related pathways are Immune System and Signaling by GPCR. GO annotations related to this gene include GTPase activator activity. An important paralog of this gene is RASA2.
UniProtKB/Swiss-Prot for RASA4 Gene
Ca(2+)-dependent Ras GTPase-activating protein, that switches off the Ras-MAPK pathway following a stimulus that elevates intracellular calcium. Functions as an adaptor for Cdc42 and Rac1 during FcR-mediated phagocytosis.
