CC   -!- FUNCTION: Exerts its effect at some terminal stage of cytochrome c
CC       oxidase synthesis, probably by being involved in the insertion of the
CC       copper B into subunit I. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane {ECO:0000250};
CC       Single-pass membrane protein {ECO:0000250}; Intermembrane side
CC       {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the COX11/CtaG family. {ECO:0000305}.
