Anti-RGS8 antibodies are used in the immunodetection of the protein regulator of G protein signaling 8. In humans, the canonical protein has a reported length of 180 amino acid residues and a mass of 20.9 kDa. Its subcellular localization is in the nucleus and cell membrane. Up to 2 different isoforms have been reported for this protein. It is notably expressed in the caudate and cerebellum. RGS8 is reported to regulate G protein-coupled receptor signaling cascades, including signaling via muscarinic acetylcholine receptor CHRM2 and dopamine receptor DRD2 (By similarity). Synonyms for this target antigen include regulator of G-protein signalling 8. RGS8 gene orthologs have been reported in the mouse, rat, bovine, chimpanzee and chicken species. Some RGS8 antibodies may have been used in research and have associated citations. These antibodies are most commonly used in Western Blot experiments, among other applications.
