Enables proton-transporting ATPase activity, rotational mechanism. Predicted to be involved in proton transmembrane transport. Predicted to act upstream of or within ion transport. Located in plasma membrane. Is expressed in several structures, including alimentary system; central nervous system; integumental system; respiratory system; and sensory organ. Orthologous to human ATP6V1C1 (ATPase H+ transporting V1 subunit C1). [provided by Alliance of Genome Resources, Apr 2022]
