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}.
