Summary: Predicted to enable ATPase binding activity and P-type proton-exporting transporter activity. Involved in synaptic vesicle lumen acidification. Acts upstream of or within proton transmembrane transport. Located in apical plasma membrane; brush border; and endosome. Part of vacuolar proton-transporting V-type ATPase complex. Is expressed in several structures, including alimentary system; genitourinary system; musculoskeletal system; respiratory system; and sensory organ. Used to study renal tubular acidosis. Human ortholog(s) of this gene implicated in renal tubular acidosis. Orthologous to human ATP6V0A4 (ATPase H+ transporting V0 subunit a4). [provided by Alliance of Genome Resources, Dec 2024]

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.
