Anti-ATP12A antibodies are used in the immunodetection of the protein ATPase H+/K+ transporting non-gastric alpha2 subunit. In humans, the canonical protein has a reported length of 1039 amino acid residues and a mass of 115.5 kDa. Its subcellular localization is in the cell membrane. Up to 2 different isoforms have been reported for this protein. It is reported to be expressed in airway epithelial cells. It is a member of the Cation transport ATPase (P-type) (TC 3.A.3) protein family. Synonyms for this target antigen include H-K-ATPase, HK, potassium-transporting ATPase alpha chain 2, ATPase, H+/K+ transporting, nongastric, alpha polypeptide, and ATP1AL1. ATP12A gene orthologs have been reported in the mouse, rat, bovine, chimpanzee and chicken species. A number of ATP12A antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
