Anti-choline dehydrogenase antibodies are used for the immunodetection of the protein encoded by the CHDH gene. In humans, the canonical protein has a reported length of 594 amino acid residues and a mass of 65.4 kDa. Its subcellular localization is in the mitochondria. It is a member of the GMC oxidoreductase protein family. Other names for this target antigen include CDH, CHD, and choline dehydrogenase, mitochondrial. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
