Summary: Enables proton transmembrane transporter activity. Involved in regulation of pH and synaptic vesicle lumen acidification. Acts upstream of or within several processes, including renal sodium excretion; renal sodium ion transport; and renal water homeostasis. Located in several cellular components, including basolateral plasma membrane; lateral plasma membrane; and microvillus. Is expressed in several structures, including limb; lower jaw; metanephros; nervous system; and sensory organ. Used to study autosomal recessive nonsyndromic deafness and enlarged vestibular aqueduct. Human ortholog(s) of this gene implicated in renal tubular acidosis. Orthologous to human ATP6V1B1 (ATPase H+ transporting V1 subunit B1). [provided by Alliance of Genome Resources, Jul 2025]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
