CC   -!- FUNCTION: Catalytic subunit of the peripheral V1 complex of vacuolar
CC       ATPase (V-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 (components A to H) attached to an integral
CC       membrane V0 proton pore complex (components: a, c, c', c'' and d).
CC   -!- SIMILARITY: Belongs to the V-ATPase G subunit family. {ECO:0000305}.
