CC   -!- FUNCTION: Required for assembly of cytochrome c oxidase (complex IV).
CC       With COX14, regulates negatively COX1 translation and is involved in
CC       MSS51 association with newly synthesized COX1 (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBUNIT: Component of 250-400 kDa complexes called cytochrome oxidase
CC       assembly intermediates or COA complexes composed at least COA3, COX14,
CC       COX5A, SHY1 and SSC1. Interacts with COX1 and MSS51. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane {ECO:0000250};
CC       Single-pass membrane protein.
CC   -!- SIMILARITY: Belongs to the COA3 family. {ECO:0000305}.
