The cytoplasmic N terminus of the Na,K-ATPase is a highly charged and flexible structure that comprises three predicted helical regions including H1 spanning residues 27 to 33 and H2 spanning residues 42 to 50. Previous deletion mutagenesis experimen

The deletion of 32 residues from the N terminus of the alpha1 catalytic subunit of the rat Na,K-ATPase (mutant alpha1M32) shifts the E(1)/E(2) conformational equilibrium toward E(1), and the combination of this deletion with mutation E233K in the M2-

Previous studies showed that the α1, α2, and α3 isoforms of the catalytic subunit of the Na,K-ATPase differ in their apparent affinities for the ligands ATP, Na+, and K+. For the rat isoforms transfected into HeLa cells,K′ATP for ATP binding at

The mechanism by which glucose stimulates insulin secretion from the pancreatic islets of Langerhans is incompletely understood. It has been suggested that malonyl-CoA plays a regulatory role by inhibiting fatty acid oxidation and promoting accumulat

A number of missense mutations in the ATP1A2 gene, which encodes the Na,K-ATPase alpha2 subunit, have been identified in familial hemiplegic migraine with aura. Loss of function and haploinsufficiency have been the suggested mechanisms in mutants for

We showed earlier that the kinetic behavior of the alpha2 isoform of the Na,K-ATPase differs from the ubiquitous alpha1 isoform primarily by a shift in the steady-state E(1)/E(2) equilibrium of alpha2 in favor of E(1) form(s). The aim of the present

To better understand the action of glucose on fatty acid metabolism in the beta-cell and the link between chronically elevated glucose or fatty acids and beta-cell decompensation in adipogenic diabetes, we investigated whether glucose regulates perox
