CC   -!- FUNCTION: Component of the coenzyme Q biosynthetic pathway. May play a
CC       role in organizing a multi-subunit COQ enzyme complex required for
CC       coenzyme Q biosynthesis. Required for steady-state levels of other COQ
CC       polypeptides (By similarity). {ECO:0000250}.
CC   -!- PATHWAY: Cofactor biosynthesis; ubiquinone biosynthesis.
CC   -!- SUBUNIT: Component of a multi-subunit COQ enzyme complex, composed of
CC       at least COQ3, COQ4, COQ5, COQ6, COQ7 and COQ9. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane {ECO:0000250};
CC       Peripheral membrane protein {ECO:0000250}; Matrix side {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the COQ4 family. {ECO:0000305}.
