ATPase, H+ transporting, lysosomal V0 subunit a4, also known as ATP6V0A4, is a human gene.cite web | title = Entrez Gene: ATP6V0A4 ATPase, H+ transporting, lysosomal V0 subunit a4| url =| accessdate = ]

section_title =
summary_text = This gene encodes a component of vacuolar ATPase (V-ATPase), a multisubunit enzyme that mediates acidification of intracellular compartments of eukaryotic cells. V-ATPase dependent acidification is necessary for such intracellular processes as protein sorting, zymogen activation, receptor-mediated endocytosis, and synaptic vesicle proton gradient generation. V-ATPase is composed of a cytosolic V1 domain and a transmembrane V0 domain. The V1 domain consists of three A and three B subunits, two G subunits plus the C, D, E, F, and H subunits. The V1 domain contains the ATP catalytic site. The V0 domain consists of five different subunits: a, c, c', c", and d. This gene is one of four genes in man and mouse that encode different isoforms of the a subunit. Alternatively spliced transcript variants encoding the same protein have been described. Mutations in this gene are associated with renal tubular acidosis associated with preserved hearing.cite web | title = Entrez Gene: ATP6V0A4 ATPase, H+ transporting, lysosomal V0 subunit a4| url =| accessdate = ]
