Anti-RGS2 antibodies are used in the immunodetection of the protein regulator of G protein signaling 2. In humans, the canonical protein has a reported length of 211 amino acid residues and a mass of 24.4 kDa. Its subcellular localization is in the cell membrane, nucleus, mitochondria, and cytoplasm. It is reported to be expressed in acute myelogenous leukemia (AML) and in acute lymphoblastic leukemia (ALL). RGS2 is reported to regulate G protein-coupled receptor signaling cascades. Synonyms for this target antigen include G0 to G1 switch regulatory 8, 24kD, G0/G1 switch regulatory protein 8, cell growth-inhibiting gene 31 protein, cell growth-inhibiting protein 31, regulator of G-protein signaling 2, 24kDa, and G0S8. RGS2 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of RGS2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
