Protein Name:
V-type proton ATPase subunit B
|
UniprotKB/SwissProt ID: P31409 (P31409)
Gene Name:
Vha55
Organism: Drosophila melanogaster (Fruit fly)
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 (By similarity). 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 (By similarity). Essential for the proper assembly and activity of V-ATPase (By similarity)
