Summary: Predicted to enable proton-transporting ATPase activity, rotational mechanism. Predicted to be involved in vacuolar acidification. Predicted to act upstream of or within ATP metabolic process and proton transmembrane transport. Predicted to be located in apical plasma membrane; melanosome; and synaptic vesicle membrane. Predicted to be part of proton-transporting V-type ATPase, V1 domain. 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, Dec 2024]

What's a GeneRIF?

atp6v1b2 knockdown zebrafish showed developmental defects in multiple organs and systems. However, Atp6v1b2 c.1516C>T knockin mice displayed obvious cognitive defects but normal hearing and cochlear morphology. Impaired hippocampal CA1 region and weaker interaction between the V1E and B2 subunits in Atp6v1b2(Arg506X//Arg506X) mice were observed

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.
