CC -!- FUNCTION: Subunit of the V0 complex of vacuolar(H+)-ATPase (V-ATPase),
CC a multisubunit enzyme composed of a peripheral complex (V1) that
CC hydrolyzes ATP and a membrane integral complex (V0) that translocates
CC protons (By similarity). V-ATPase is responsible for acidifying and
CC maintaining the pH of intracellular compartments and in some cell
CC types, is targeted to the plasma membrane, where it is responsible for
CC acidifying the extracellular environment (By similarity).
CC {ECO:0000250|UniProtKB:Q2KIB5}.
CC -!- SUBUNIT: V-ATPase is a heteromultimeric enzyme made up of two
CC complexes: the ATP-hydrolytic V1 complex and the proton translocation
CC V0 complex. The V1 complex consists of three catalytic AB heterodimers
CC that form a heterohexamer, three peripheral stalks each consisting of
CC EG heterodimers, one central rotor including subunits D and F, and the
CC regulatory subunits C and H. The proton translocation complex V0
CC consists of the proton transport subunit a, a ring of proteolipid
CC subunits c9c'', rotary subunit d, subunits e and f, and the accessory
CC subunits ATP6AP1/Ac45 and ATP6AP2/PRR. {ECO:0000250|UniProtKB:Q2KIB5}.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000255}; Multi-pass membrane
CC protein {ECO:0000255}. Cytoplasmic vesicle, clathrin-coated vesicle
CC membrane {ECO:0000250|UniProtKB:Q5EB76}; Multi-pass membrane protein
CC {ECO:0000255}. Cytoplasmic vesicle, secretory vesicle, synaptic vesicle
CC membrane {ECO:0000250|UniProtKB:Q5EB76}; Multi-pass membrane protein
CC {ECO:0000255}.
CC -!- SIMILARITY: Belongs to the V-ATPase e1/e2 subunit family.
CC {ECO:0000305}.
