Predicted to enable ATP binding activity and hydrolase activity. Predicted to be involved in ATP metabolic process and proton transmembrane transport. Predicted to act upstream of or within ion transport. Located in several cellular components, including apical plasma membrane; microvillus; and ruffle. Is expressed in several structures, including genitourinary system; integumental system; limb; nervous system; and sensory organ. Used to study autosomal dominant congenital deafness with onychodystrophy. Human ortholog(s) of this gene implicated in autosomal dominant congenital deafness with onychodystrophy. Orthologous to human ATP6V1B2 (ATPase H+ transporting V1 subunit B2). [provided by Alliance of Genome Resources, Apr 2022]
