Anti-ADH7 antibodies are used in the immunodetection of the protein alcohol dehydrogenase 7 (class IV), mu or sigma polypeptide. In humans, the canonical protein has a reported length of 386 amino acid residues and a mass of 41.5 kDa. Its subcellular localization is in the cytoplasm. Up to 2 different isoforms have been reported for this protein. It is found to be highly expressed in the stomach. A member of the Zinc-containing alcohol dehydrogenase protein family, ADH7 is known to catalyze the NAD-dependent oxidation of all-trans-retinol, alcohol, and omega-hydroxy fatty acids and their derivatives. Synonyms for this target antigen include all-trans-retinol dehydrogenase [NAD(+)] ADH7, alcohol dehydrogenase VII, alcohol dehydrogenase class 4 mu/sigma chain, alcohol dehydrogenase class IV mu/sigma chain, and ADH4. ADH7 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species.
