Anti-MTCP1NB antibodies enable researchers to detect and measure the MTCP1NB antigen in biological samples. This target is a reported synonym of the CMC4 gene, which encodes C-X9-C motif containing 4. The human version of MTCP1NB has a canonical amino acid length of 68 residues and a protein mass of 7.7 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the mitochondria of cells and widely expressed in many tissue types. MTCP1NB is a member of the CMC4 protein family.
