ATP6V1G1 is a subunit of vacuolar ATPase (V-ATPase), a multisubunit enzyme. V-ATPase is an enzyme transporter that functions to acidify intracellular compartments in eukaryotic cells. This acidification process is necessary for such intracellular processes as protein sorting, zymogen activation, receptor-mediated endocytosis, and synaptic vesicle proton gradient generation. V-ATPase is ubiquitously expressed and is present in endomembrane organelles such as vacuoles, lysosomes, endosomes, the Golgi apparatus, chromaffin granules and coated vesicles, as well as in the plasma membrane. V-ATPase is composed of a cytosolic V1 domain and a transmembrane V0 domain. The V1 domain consists of three A, three B, and two G subunits, as well as a C, D, E, F, and H subunit. The V1 domain contains the ATP catalytic site.
