Reversibility of Na+/Mg2+ antiport in rat erythrocytes |pdf=|usr=}}{{7880850}} gab.com Text Reversibility of Na+/Mg2+ antiport in rat erythrocytes JO: Biochim Biophys Acta http://www.kidney.de/pget.php?&tw=1&pmid=7880850 #FOAvip Rat erythrocytes loaded with Mg2+ plus Na+ performed Mg2+ uptake under an intracellular/extracellular Na+ gradient. Mg2+ uptake was coupled to Na+ release at a stoichiometric ratio of 1 Mg2+/2 Na+.Mg2+ uptake was inhibited by amiloride, imipramine and quinidine. Mn2+ was taken up by the same transporter as Mg2+. Similar results had been found for net Mg2+ efflux via Na+/Mg2+ antiport in such rat erythrocytes. Hence, it can be concluded that Na+/Mg2+ antiport in Mg(2+)-loaded rat erythrocytes operates reversibly according to the direction of the Na+ gradient which is a contributing driving force. Net Mg2+ influx was dependent on ATP which increased the affinity of intracellular Mg2+ by activating Na+/Mg2+ antiport. Mg2+ uptake was increased by phorbol ester and inhibited by staurosporine, indicating that ATP may function via protein phosphorylation by protein kinase C.
