Anti-ATP6V1G2 antibodies are used in the immunodetection of the protein ATPase H+ transporting V1 subunit G2. In humans, the canonical protein has a reported length of 118 amino acid residues and a mass of 13.6 kDa. Its subcellular localization is in the cytoplasmic vesicles and membrane. Up to 3 different isoforms have been reported for this protein. It is notably expressed in the brain. A member of the V-ATPase G subunit protein family, ATP6V1G2 is a known subunit of the V1 complex of vacuolar(H+)-ATPase (V-ATPase), a multisubunit enzyme composed of a peripheral complex (V1) that hydrolyzes ATP and a membrane integral complex (V0) that translocates protons. Synonyms for this target antigen include ATP6G2, NG38, VMA10, V-type proton ATPase subunit G 2, and ATP6G. ATP6V1G2 gene orthologs have been reported in the mouse, rat, bovine, frog and chimpanzee species. Some ATP6V1G2 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
