Anti-B14 antibodies enable researchers to detect and measure the B14 antigen in biological samples. This target is a reported synonym of the NDUFA6 gene, which encodes NADH:ubiquinone oxidoreductase subunit A6. This protein is known to function in the response to oxidative stress, among other biological roles. The human version of B14 has a canonical amino acid length of 128 residues and a protein mass of 15.1 kilodaltons. It is reported to be localized in the mitochondria of cells. Other names for this target antigen include CI-B14 and LYRM6.
