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 Myometrial Relaxation and Contraction Pathways and Signaling by GPCR. GO annotations related to this gene include GTPase activator activity. An important paralog of this gene is RGS4.
UniProtKB/Swiss-Prot 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.
