VMA2
Function
Non-catalytic 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 (PubMed:2141385). V-ATPase is responsible for acidifying and maintaining the pH of intracellular compartments (PubMed:2141385).
Sequence Similarities
Belongs to the ATPase alpha/beta chains family.
Cellular localization
- Vacuole membrane
- Peripheral membrane protein
- Cytoplasmic side
