function:Catalytic subunit of the peripheral V1 complex of vacuolar ATPase (V-ATPase). V-ATPase is responsible for acidifying a variety of intracellular compartments in eukaryotic cells.,similarity:Belongs to the V-ATPase G subunit family.,subcellular location:Highly enriched in late-stage melanosomes.,subunit:V-ATPase is an heteromultimeric enzyme composed of a peripheral catalytic V1 complex (components A to H) attached to an integral membrane V0 proton pore complex (components: a, c, c', c'' and d).,tissue specificity:Brain.,
Melanosome . Cytoplasmic vesicle, clathrin-coated vesicle membrane ; Peripheral membrane protein . Highly enriched in late-stage melanosomes. .
