View in BioMuta


COX7A1, cytochrome c oxidase subunit VIIa polypeptide 1 (muscle), is one of the polypeptide chains of cytochrome c oxidase, the terminal component of the mitochondrial respiratory chain. This polypeptide is present only in muscle tissues. Other polypeptides of subunit VIIa are present in both muscle and nonmuscle tissues, and are encoded by different genes.
