Biological Properties

General Function

Energy production and conversion

Specific Function

Subunit of the integral membrane V0 complex of vacuolar ATPase essential for assembly and catalytic activity. Is present only in Golgi- and endosome-residing V-ATPase complexes. Enzymes containing this subunit have a 4-fold lower ratio of proton transport to ATP hydrolysis than complexes containing the vacuolar isoform and do not dissociate V1 and V0 in response to glucose depletion. V-ATPase is responsible for acidifying a variety of intracellular compartments in eukaryotic cells
