This entry represents a coiled-coil domain found in cytochrome c oxidase assembly factor 3 and homologues. Cytochrome c oxidase assembly factor 3, previously known as coiled coil domain-containing protein 56 (CCDC56), plays a critical role in the biogenesis and activity of cytochrome c oxidase (COX) [1].
