Anti-C-x(9)-C motif containing 1 antibodies enable researchers to detect and measure the C-x(9)-C motif containing 1 antigen in biological samples. This target is a reported synonym of the CMC1 gene, which encodes C-X9-C motif containing 1. This protein is a known component of the MITRAC (mitochondrial translation regulation assembly intermediate of cytochrome c oxidase complex) complex, that regulates cytochrome c oxidase assembly. The human version of C-x(9)-C motif containing 1 has a canonical amino acid length of 106 residues and a protein mass of 12.5 kilodaltons. It is reported to be localized in the mitochondria of cells and widely expressed in many tissue types. Other names for this target antigen include COX assembly mitochondrial protein homolog and C-x(9)-C motif containing 1.
