Inward rectifying k channel
Web10 jun. 2015 · In the present work, the SsAKT1 gene encoding the inward-rectifying K + channel was isolated from S. salsa, and its function in K + transport characterized by yeast complementation assays. Finally, the expression patterns of SsAKT1 in roots exposed to different KCl or NaCl concentrations were analyzed. Web8 aug. 2014 · The K ir channels are selective for K + ions, and consequently the reversal potentials of the inward rectifying current for different extracellular K + concentrations should always follow the Nernstian equilibrium potential for potassium (Figures 1E, 3A ).
