Predicted to enable proton-transporting ATPase activity, rotational mechanism. Predicted to be involved in cilium assembly and protein localization to cilium. Predicted to act upstream of or within cell projection organization and ion transport. Predicted to be located in membrane. Predicted to be part of proton-transporting V-type ATPase complex. Predicted to colocalize with centrosome and cilium. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; integumental system; and sensory organ. Orthologous to human ATP6V1D (ATPase H+ transporting V1 subunit D). [provided by Alliance of Genome Resources, Apr 2022]
