CC   -!- FUNCTION: Subunit of the peripheral V1 complex of vacuolar ATPase
CC       essential for assembly or catalytic function. V-ATPase is responsible
CC       for acidifying a variety of intracellular compartments in eukaryotic
CC       cells (By similarity). {ECO:0000250}.
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 E subunit family. {ECO:0000305}.
