General annotation (Comments)

Function

Electron carrier protein. The oxidized form of the cytochrome c heme group can accept an electron from the heme group of the cytochrome c1 subunit of cytochrome reductase. Cytochrome c then transfers this electron to the cytochrome oxidase complex, the final protein carrier in the mitochondrial electron-transport chain.

Subcellular location

Mitochondrion intermembrane space. Note: Loosely associated with the inner membrane.

Post-translational modification

Binds 1 heme group per subunit.

Sequence similarities

Belongs to the cytochrome c family.
