Previous GeneCards Identifiers for RGS3 Gene
This gene encodes a member of the regulator of G-protein signaling (RGS) family. This protein is a GTPase-activating protein that inhibits G-protein-mediated signal transduction. Alternative splicing and the use of alternative promoters results in multiple transcript variants encoding different isoforms. Long isoforms are largely cytosolic and plasma membrane-associated with a function in Wnt signaling and in the epithelial mesenchymal transition, while shorter N-terminally-truncated isoforms can be nuclear.

GeneCards Summary for RGS3 Gene
RGS3 (Regulator Of G Protein Signaling 3) is a Protein Coding gene. Among its related pathways are G-AlphaQ Signaling and Signaling by GPCR. Gene Ontology (GO) annotations related to this gene include GTPase activator activity. An important paralog of this gene is RGS12.
UniProtKB/Swiss-Prot Summary for RGS3 Gene
Down-regulates signaling from heterotrimeric G-proteins by increasing the GTPase activity of the alpha subunits, thereby driving them into their inactive GDP-bound form. Down-regulates G-protein-mediated release of inositol phosphates and activation of MAP kinases.
