Atp6v1b2 Gene Summary [Mouse]
Predicted to enable proton-transporting ATPase activity, rotational mechanism. Involved in synaptic vesicle lumen acidification. Located in several cellular components, including apical plasma membrane; microvillus; and ruffle. Is expressed in several structures, including alimentary system; genitourinary system; integumental system; nervous system; and sensory organ. Used to study autosomal dominant congenital deafness with onychodystrophy and epilepsy. 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, Jul 2025]
