V-type proton ATPase catalytic subunit A

UniProtKB accession:  P17255

Grouped By:  Matching UniProtKB accession

UniProtKB description:  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:2139027, PubMed:18055462). V-ATPase is responsible for acidifying and maintaining the pH of intracellular compartments (PubMed:2139027, PubMed:18055462).
