Anti-ATP6V0A1 antibodies are used in the immunodetection of the protein ATPase H+ transporting V0 subunit a1. In humans, the canonical protein has a reported length of 837 amino acid residues and a mass of 96.4 kDa. Its subcellular localization is in the cytoplasmic vesicles. Up to 3 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the V-ATPase 116 kDa subunit protein family, ATP6V0A1 is a known subunit of the V0 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 transports protons across cellular membranes. Synonyms for this target antigen include ATP6N1A, DEE104, NEDEBA, Stv1, VPP1, Vph1, a1, and ATP6N1. ATP6V0A1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 50 citations in the literature describe the use of ATP6V0A1 antibodies in research. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
