Anti-cox-5A antibodies enable researchers to detect and measure the cox-5A antigen in biological samples. This target is a reported synonym of the COX5A gene, which encodes cytochrome c oxidase subunit 5A. This protein is known to function in electron transport, among other biological roles. The human version of cox-5A has a canonical amino acid length of 150 residues and a protein mass of 16.8 kilodaltons. It is reported to be localized in the mitochondria of cells and widely expressed in many tissue types. cox-5A is a member of the Cytochrome c oxidase subunit 5A protein family.
