CC   -!- FUNCTION: Essential for the assembly of ubiquinol-cytochrome c
CC       reductase. It has a direct effect on the correct occurrence of the
CC       Rieske protein, core 4, core 5 and apocytochrome b (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane {ECO:0000250};
CC       Single-pass membrane protein {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the CBP4 family. {ECO:0000305}.
