| Description | Purity: > 90% by SDS - PAGE Format: Liquid. In Phosphate buffered saline (pH7.4) containing, 50% glycerol, 1mM DTT . ATP6V1F is 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. Recombinant human ATP6V1F, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques. |
