Anti-MTND2 antibodies enable researchers to detect and measure the MTND2 antigen in biological samples. This target is a reported synonym of the MT-ND2 gene, which encodes mitochondrially encoded NADH dehydrogenase 2. This protein is known to function in electron transport, among other biological roles. The human version of MTND2 has a canonical amino acid length of 347 residues and a protein mass of 39 kilodaltons. It is reported to be localized in the mitochondria of cells. MTND2 is a member of the Complex I subunit 2 protein family.
