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}.
