V-ATPase A1 Antibody (E-8) is a high quality monoclonal V-ATPase A1 antibody (also designated ATP6V0A1 antibody, VPP1 antibody, ATPase H+ Transporting V0 Subunit A1 antibody, ATP6N1A antibody, ATP6N1 antibody, Stv1 antibody, VPP1 antibody, Vph1 antibody, A1 antibody, ATPase H+ Transporting Lysosomal Non-Catalytic Accessory Protein 1 (110/116kD) antibody, V-ATPase 116 KDa Subunit A1 antibody, or V-ATPase 116 KDa antibody) suitable for the detection of the V-ATPase A1 protein of mouse, rat and human origin. V-ATPase A1 Antibody (E-8) is available as both the non-conjugated anti-V-ATPase A1 antibody form, as well as multiple conjugated forms of anti-V-ATPase A1 antibody, including agarose, HRP, PE, FITC and multiple Alexa Fluor® conjugates. The subunit of the vacuolar proton pump is a V-ATPase that has two different isoforms. The type I isoform contains an 18-base pair insert and is expressed in brain, whereas the truncated type II isoform is more widely expressed, including lung, kidney and spleen. The subunit of the vacuolar proton pump is located in clathrin-coated vesicles and is also found in osteoclasts. It consists of two fundamental domains, a hydrophilic amino-terminus, which has greater than 30% charged residues, and a hydrophobic carboxy terminus, which contains at least six transmembrane regions. The proton pump functions in coupling ATP hydrolysis by the cytoplasmic subunits to proton translocation by the intramembranous components of the pump. The inactivation of the osteoclast-specific vacuolar proton ATPase subunit is responsible for the lack of the enzyme in the apical membranes of osteoclast cells in osteosclerotic mutant mice, thus preventing the resorption function of these cells and leading to the osteopetrotic phenotype. The subunit, which co-localizes with the late endosomal marker Rab7 on vacuolar membranes, is essential for vacuole formation by selective swelling of late endosomes.
