CC   -!- FUNCTION: Proton-conducting pore forming subunit of the membrane
CC       integral V0 complex of vacuolar ATPase. V-ATPase is responsible for
CC       acidifying a variety of intracellular compartments in eukaryotic cells.
CC   -!- SUBUNIT: V-ATPase is a heteromultimeric enzyme composed of a peripheral
CC       catalytic V1 complex (main components: subunits A, B, C, D, E, and F)
CC       attached to an integral membrane V0 proton pore complex (main
CC       component: the proteolipid protein; which is present as a hexamer that
CC       forms the proton-conducting pore).
CC   -!- SUBCELLULAR LOCATION: Vacuole membrane; Multi-pass membrane protein.
CC       Note=Tonoplast.
CC   -!- SIMILARITY: Belongs to the V-ATPase proteolipid subunit family.
CC       {ECO:0000305}.
