GENE INFORMATION
Gene name	ATP6AP1 (HGNC Symbol)
Synonyms	16A, Ac45, ATP6IP1, ATP6S1, CF2, ORF, VATPS1, XAP-3, XAP3
Description	ATPase, H+ transporting, lysosomal accessory protein 1 (HGNC Symbol)
Entrez gene summary	This gene encodes a component of a multisubunit enzyme that mediates acidification of eukaryotic intracellular organelles. Vacuolar ATPase (V-ATPase) is comprised of a cytosolic V1 (site of the ATP catalytic site) and a transmembrane V0 domain. V-ATPase dependent organelle acidification is necessary for such intracellular processes as protein sorting, zymogen activation, and receptor-mediated endocytosis. The encoded protein of this gene may assist in the V-ATPase-mediated acidification of neuroendocrine secretory granules. This protein may also play a role in early development.
