CC   -!- FUNCTION: This is one of the chains of the nonenzymatic component
CC       (CF(0) subunit) of the mitochondrial ATPase complex. {ECO:0000250}.
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 (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion membrane {ECO:0000250}; Single-pass
CC       membrane protein {ECO:0000250}.
CC   -!- RNA EDITING: Modified_positions=50, 96;
CC   -!- SIMILARITY: Belongs to the ATPase protein MI25 family. {ECO:0000305}.
