UniProtKB description: Subunit of the V0 complex of vacuolar(H+)-ATPase (V-ATPase), a multisubunit enzyme composed of a peripheral complex (V1) that hydrolyzes ATP and a membrane integral complex (V0) that translocates protons (PubMed:11278748, PubMed:7514599). V-ATPase is responsible for acidifying and maintaining the pH of intracellular compartments (PubMed:11278748, PubMed:7514599). 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 (PubMed:11278748, PubMed:7514599).
