Protein Classification

COX20 family protein( domain architecture ID 38241)

COX20 family protein is a DUF3767 domain-containing protein; similar to Mus musculus mitochondrial cytochrome c oxidase assembly protein COX20, which is essential for the assembly of the mitochondrial respiratory chain complex IV (CIV), also known as cytochrome c oxidase

Cytochrome c oxidase assembly protein COX20; Complex IV (CIV) is a copper-heme oxidase that couples electron transfer from cytochrome c to oxygen with proton extrusion across the inner membrane to contribute to the proton gradient required for ATP generation. This entry includes fungal mitochondrial complex IV assembly factor Cox20 and its homologs (also known as FAM36A in metazoa. Human CIV is formed by three catalytic core subunits (COX1/2/3). COX20 has been found to form a complex with SCO1, SCO2, and newly synthesized COX2. It may act as a chaperone in the early steps of COX2 maturation.
