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   -!- FUNCTION: Plays a role in apoptosis. Suppression of the anti-apoptotic
CC       members or activation of the pro-apoptotic members of the Bcl-2 family
CC       leads to altered mitochondrial membrane permeability resulting in
CC       release of cytochrome c into the cytosol. Binding of cytochrome c to
CC       Apaf-1 triggers the activation of caspase-9, which then accelerates
CC       apoptosis by activating other caspases (By similarity). {ECO:0000250}.
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   -!- PTM: Phosphorylation at Tyr-49 and Tyr-98 both reduce by half the
CC       turnover in the reaction with cytochrome c oxidase, down-regulating
CC       mitochondrial respiration. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the cytochrome c family. {ECO:0000305}.
