Anti-NDUFAB1 antibodies are used in the immunodetection of the protein NADH:ubiquinone oxidoreductase subunit AB1. In humans, the canonical protein has a reported length of 156 amino acid residues and a mass of 17.4 kDa. Its subcellular localization is in the mitochondria. It is notably widely expressed in many tissue types. A member of the Acyl carrier protein (ACP) protein family, NDUFAB1 is known to be involved with electron transport. Synonyms for this target antigen include ACP1, FASN2A, SDAP, acyl carrier protein, mitochondrial, CI-SDAP, and ACP. NDUFAB1 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species.
