CC   -!- FUNCTION: Non-catalytic subunit of the peripheral V1 complex of
CC       vacuolar ATPase. V-ATPase is responsible for acidifying a variety of
CC       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).
CC   -!- SIMILARITY: Belongs to the ATPase alpha/beta chains family.
CC       {ECO:0000305}.
