Listed are ELISA Kits for the detection of cytochrome c oxidase assembly factor 4, an alias name of cytochrome c oxidase assembly factor 4 homolog. The human protein, encoded by the gene COA4, is 87 amino acid residues long and has a mass of 10,134 daltons. However, there are up to 2 reported isoforms. It is a member of the COA4 family. This protein is reported to have a mitochondrial cellular localization. This target may also be known as: cytochrome c oxidase assembly factor 4 homolog mitochondrial, E2-induced gene 2 protein, coiled-coil-helix-coiled-coil-helix domain containing 8, coiled-coil-helix-coiled-coil-helix domain-containing protein 8, CMC3, and E2IG2.
