Predicted to enable proton-transporting ATPase activity, rotational mechanism. Predicted to be involved in proton transmembrane transport. Predicted to be part of proton-transporting V-type ATPase, V0 domain. Is an ortholog of C. elegans
vha-1. In C. elegans,
vha-1 is involved in several processes, including lysosomal lumen acidification; ovulation; and regulation of syncytium formation by plasma membrane fusion.
