CC -!- FUNCTION: Copper metallochaperone essential for the synthesis and
CC maturation of cytochrome c oxidase subunit II (MT-CO2/COX2). Involved
CC in transporting copper to the Cu(A) site on MT-CO2/COX2. Also acts as a
CC thiol-disulfide oxidoreductase to regulate the redox state of the
CC cysteines in SCO1 during maturation of MT-CO2/COX2.
CC {ECO:0000250|UniProtKB:O43819}.
CC -!- SUBUNIT: Homodimer. Interacts with COA6. Found in a complex with
CC TMEM177, COX20, COA6, MT-CO2/COX2, COX18 and SCO1. Interacts with
CC TMEM177 in a COX20-dependent manner. Interacts with COX20 in a MT-
CC CO2/COX2- and COX18-dependent manner. Interacts with COX16.
CC {ECO:0000250|UniProtKB:O43819}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane
CC {ECO:0000250|UniProtKB:O43819}; Single-pass membrane protein
CC {ECO:0000255}.
CC -!- SIMILARITY: Belongs to the SCO1/2 family. {ECO:0000305}.
