Anti-NDUFC2-KCTD14 readthrough antibodies are used for the immunodetection of the protein encoded by the NDUFC2-KCTD14 gene. In humans, the canonical protein has a reported length of 114 amino acid residues and a mass of 13.4 kDa. Its subcellular localization is in the mitochondria. Alternative splicing is reported to yield 3 different isoforms for this protein. A member of the Complex I NDUFC2 subunit protein family, it is reported to be an accessory subunit the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I), that is believed not to be involved in catalysis. Other names for this target antigen include NADH dehydrogenase [ubiquinone] 1 subunit C2, NDUFC2-KCTD14 readthrough transcript protein, and NADH dehydrogenase [ubiquinone] 1 subunit C2, isoform 2.
