Predicted to enable proton-transporting ATPase activity, rotational mechanism. Predicted to be involved in proton transmembrane transport. Predicted to be part of vacuolar proton-transporting V-type ATPase, V0 domain. Is an ortholog of C. elegans
unc-32 and members of the C. elegans vha gene class including
vha-7. In C. elegans,
unc-32 is involved in several processes, including cholinergic synaptic transmission; positive regulation of neurotransmitter secretion; and response to stress.
