Predicted to enable proton-transporting ATPase activity, rotational mechanism. Predicted to be involved in vacuolar acidification and vacuolar transport. Predicted to be located in early endosome. Predicted to be part of plasma membrane proton-transporting V-type ATPase complex and vacuolar proton-transporting V-type ATPase complex. Expressed in head and tail. Is an ortholog of human ATP6V0D1 (ATPase H+ transporting V0 subunit
d1).
