General description
The H+/K+-ATPase is a gastric proton pump that is a member of the P-type cation-transporting adenosine 5′-triphosphatase (ATPase) family. H+/K+-ATPase consists of a large transmembrane, catalytic α subunit, that contains sites for ATP binding and phosphorylation. This ATPase also has a smaller glycoprotein (β) subunit which may play a role in maintaining the structural and functional integrity of the complex. Mouse monoclonal anti-H+/K+ ATPase (β subunit) binds to H+/K+-ATPase β subunit in cow, dog, pig, rabbit, mouse, ferret and rat tissues. By immunoblotting, the antibody detects various forms of the β subunit, including a 60-80kDa glycosylated protein, a 52kDa β subunit precursor and the 34kDa core peptide.
The antibody reacts with various forms of the H+/K+ ATPase β subunit. It binds an epitope within amino acids 1-13 or 15-28 located on the cytoplasmic side of the β subunit. The antibody has been shown to inhibit the enzymatic activity of the H+/K+-ATPase and to alter the affinity of the cytoplasmic K+ binding site. It may be used to localize and detect H+/K+ ATPase β subunit.

Pancreatic duct cells are equipped with acid/base transporters important for exocrine secretion. Pancreatic ductal adenocarcinoma (PDAC) cells may utilize such transporters to acidify extracellular tumor microenvironment, creating a niche favoring cell proliferation, fibrosis and resistance to chemotherapy-all contributing to the
