CC   -!- FUNCTION: This protein is one of the chains of the nonenzymatic
CC       membrane component (F0) of mitochondrial ATPase.
CC   -!- SUBUNIT: F-type ATPases have 2 components, CF(1) - the catalytic core
CC       - and CF(0) - the membrane proton channel. CF(1) has five subunits:
CC       alpha(3), beta(3), gamma(1), delta(1), epsilon(1). CF(0) has three main
CC       subunits: a, b and c.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion membrane {ECO:0000305}; Multi-pass
CC       membrane protein {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the ATPase C chain family. {ECO:0000305}.
