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. {ECO:0000255|HAMAP-Rule:MF_03111}.
CC   -!- PATHWAY: Cofactor biosynthesis; ubiquinone biosynthesis.
CC       {ECO:0000255|HAMAP-Rule:MF_03111}.
CC   -!- SUBUNIT: Component of a multi-subunit COQ enzyme complex.
CC       {ECO:0000255|HAMAP-Rule:MF_03111}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_03111}; Peripheral membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_03111}; Matrix side {ECO:0000255|HAMAP-Rule:MF_03111}.
CC   -!- MISCELLANEOUS: This protein may be expected to contain an N-terminal
CC       transit peptide but none has been predicted. {ECO:0000255|HAMAP-
CC       Rule:MF_03111}.
CC   -!- SIMILARITY: Belongs to the COQ4 family. {ECO:0000255|HAMAP-
CC       Rule:MF_03111}.
CC   -!- CAUTION: The coq-4 gene is duplicated in C.briggsae to produce coq-4.1
CC       and coq-4.2. coq-4.1 encodes a longer functional protein while coq-4.2
CC       is shorter and may be non-functional or have acquired a different
CC       function to coq-4.1. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=CAP31025.2; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
