Predicted to enable ATP hydrolysis activity and proton-transporting ATPase activity, rotational mechanism. Predicted to be involved in proton transmembrane transport. Predicted to be integral component of synaptic vesicle membrane. Predicted to be part of vacuolar proton-transporting V-type ATPase complex. Orthologous to human ATP6V1G2 (ATPase H+ transporting V1 subunit G2). [provided by Alliance of Genome Resources, Apr 2022]
