Summary: This gene encodes a subunit of vacuolar ATPase, a multimeric enzyme that localizes to intracellular vesicles and to the plasma membrane of specialized cells. The encoded protein is a component of the V(0) domain, which functions in proton translocation across membranes. Function of this gene is important in fetal-specific immune suppression during pregnancy. [provided by RefSeq, May 2013]

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.
