CC -!- FUNCTION: Non-catalytic subunit of the V1 complex of vacuolar(H+)-
CC ATPase (V-ATPase), a multisubunit enzyme composed of a peripheral
CC complex (V1) that hydrolyzes ATP and a membrane integral complex (V0)
CC that translocates protons (By similarity). V-ATPase is responsible for
CC acidifying and maintaining the pH of intracellular compartments (By
CC similarity). {ECO:0000250|UniProtKB:P16140}.
CC -!- SUBUNIT: V-ATPase is a heteromultimeric enzyme composed of a peripheral
CC catalytic V1 complex (components A to H) attached to an integral
CC membrane V0 proton pore complex (components: a, c, c', c'', d, e, f and
CC VOA1) (By similarity). Interacts with rav1 (PubMed:18441123).
CC {ECO:0000250|UniProtKB:P16140, ECO:0000269|PubMed:18441123}.
CC -!- SUBCELLULAR LOCATION: Vacuole membrane {ECO:0000250|UniProtKB:P16140};
CC Peripheral membrane protein {ECO:0000305}; Cytoplasmic side
CC {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the ATPase alpha/beta chains family.
CC {ECO:0000305}.
