CC -!- FUNCTION: Electron carrier protein. The oxidized form of the cytochrome
CC c heme group can accept an electron from the heme group of the
CC cytochrome c1 subunit of cytochrome reductase. Cytochrome c then
CC transfers this electron to the cytochrome oxidase complex, the final
CC protein carrier in the mitochondrial electron-transport chain (By
CC similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion intermembrane space {ECO:0000250}.
CC Note=Loosely associated with the inner membrane. {ECO:0000250}.
CC -!- PTM: Binds 1 heme c group covalently per subunit. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the cytochrome c family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=CAJ83237.1; Type=Erroneous initiation; Evidence={ECO:0000305};
