Predicted to enable proton-transporting ATPase activity, rotational mechanism. Involved in embryo development; embryonic body morphogenesis; and regulation of syncytium formation by plasma membrane fusion. Located in apical junction complex and apical plasma membrane. Expressed in excretory cell; hypodermal cell; and intestine. Is an ortholog of human ATP6V0E2 (ATPase H+ transporting V0 subunit
e2).
