Abstract excerpt
The H,K-ATPase responsible for gastric acidification is a heterodimeric (alpha and beta subunit) P-type ATPase, an integral protein of parietal cell apical membranes, which promotes the electroneutral exchange of K+ for protons, is stimulated by K+ and is inhibited by 2-methyl-8-(phenylmethoxy)imidazo[1, 2-alpha]pyridine-3-acetonitrile (SCH 28080). Hydropathy analysis of the catalytic alpha subunit has been...
