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.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion intermembrane space. Note=Loosely
CC       associated with the inner membrane.
CC   -!- PTM: Binds 1 heme c group covalently per subunit.
CC   -!- SIMILARITY: Belongs to the cytochrome c family. {ECO:0000305}.
