Anti-coenzyme Q5 methyltransferase antibodies enable researchers to detect and measure the coenzyme Q5 methyltransferase antigen in biological samples. This target is a reported synonym of the COQ5 gene, which encodes coenzyme Q5, methyltransferase. The human version of coenzyme Q5 methyltransferase has a canonical amino acid length of 327 residues and a protein mass of 37.1 kilodaltons. It is reported to be localized in the mitochondria of cells and widely expressed in many tissue types. coenzyme Q5 methyltransferase is a member of the MenG/UbiE protein family.
