CC   -!- FUNCTION: Component of the ubiquinol-cytochrome c reductase complex
CC       (complex III or cytochrome b-c1 complex) that is part of the
CC       mitochondrial respiratory chain. The b-c1 complex mediates electron
CC       transfer from ubiquinol to cytochrome c. Contributes to the generation
CC       of a proton gradient across the mitochondrial membrane that is then
CC       used for ATP synthesis. {ECO:0000256|ARBA:ARBA00002566}.
CC   -!- SUBCELLULAR LOCATION: Membrane {ECO:0000256|ARBA:ARBA00004141}; Multi-
CC       pass membrane protein {ECO:0000256|ARBA:ARBA00004141}. Mitochondrion
CC       inner membrane {ECO:0000256|ARBA:ARBA00004448}; Multi-pass membrane
CC       protein {ECO:0000256|ARBA:ARBA00004448}.
