V-type proton ATPase 116 kDa subunit a 1

UniProtKB accession:  P25286

Grouped By:  Matching UniProtKB accession

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:32165585). V-ATPase is responsible for the acidification of various organelles, such as lysosomes, endosomes, the trans-Golgi network, and secretory granules, including synaptic vesicles (PubMed:32165585). In certain cell types, can be exported to the plasma membrane, where it is involved in the acidification of the extracellular environment (PubMed:32165585). Required for assembly and activity of the vacuolar ATPase (By similarity). Through its action on compartment acidification, plays an essential role in neuronal development in terms of integrity and connectivity of neurons (By similarity).
