UniProt ID: Q6PBR5 |
FUNCTION: Subunit of the V1 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. V-ATPase is responsible for acidifying and maintaining the pH of intracellular compartments and in some cell types, is targeted to the plasma membrane, where it is responsible for acidifying the extracellular environment. {ECO:0000256|RuleBase:RU364019}. SUBUNIT: V-ATPase is a heteromultimeric enzyme made up of two complexes: the ATP-hydrolytic V1 complex and the proton translocation V0 complex. {ECO:0000256|RuleBase:RU364019}. SIMILARITY: Belongs to the V-ATPase G subunit family. {ECO:0000256|ARBA:ARBA00010066, ECO:0000256|RuleBase:RU364019}. |
