Anti-RGS22 antibodies are used in the immunodetection of the protein regulator of G protein signaling 22. In humans, the canonical protein has a reported length of 1264 amino acid residues and a mass of 147.2 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 3 different isoforms have been reported for this protein. It is reported to have testis-specific expression. RGS22 is known to inhibit signal transduction by increasing the GTPase activity of G protein alpha subunits thereby driving them into their inactive GDP-bound form. Synonyms for this target antigen include CT145 and PRTD-NY2. RGS22 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some RGS22 antibodies may have been used in research and have associated citations. ELISA, Western Blot, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are common applications for these antibodies.
