Rabbit Monoclonal Antibody to ATP6V0D1

This gene encodes a component of vacuolar ATPase (V~ATPase), a multisubunit enzyme that mediates acidification of eukaryotic intracellular organelles. V~ATPase dependent organelle 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. Additional isoforms of many of the V1 and V0 subunit proteins are encoded by multiple genes or alternatively spliced transcript variants. This encoded protein is known as the D subunit and is found ubiquitously. [provided by RefSeq, Jul 2008]
