Predicted to enable proton-transporting ATPase activity, rotational mechanism. Predicted to be involved in endocytosis. Predicted to act upstream of or within ion transport. Predicted to be part of vacuolar proton-transporting V-type ATPase, V1 domain. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; integumental system; and sensory organ. Orthologous to human ATP6V1H (ATPase H+ transporting V1 subunit H). [provided by Alliance of Genome Resources, Apr 2022]
