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. V-ATPase is responsible for acidifying and
CC maintaining the pH of intracellular compartments.
CC {ECO:0000256|RuleBase:RU366021}.
CC -!- SUBUNIT: V-ATPase is a heteromultimeric enzyme composed of a peripheral
CC catalytic V1 complex attached to an integral membrane V0 proton pore
CC complex. {ECO:0000256|RuleBase:RU366021}.
CC -!- SIMILARITY: Belongs to the ATPase alpha/beta chains family.
CC {ECO:0000256|ARBA:ARBA00008936, ECO:0000256|RuleBase:RU366021}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:PXF41674.1}.
