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.

Kir4.1 channels were found to colocalize with the H(+)/K(+)-ATPase throughout the parietal cell (PC) acid secretory cycle. This study was undertaken to explore their functional role. Acid secretory rates, electrophysiological parameters, PC ultrastructure, and gene and protein expression were determined

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
