WebMay 25, 2007 · Properties of the plasma membrane SOS1 protein from Arabidopsis thaliana, a highly specific Na+/H+ exchanger that catalyses Na+ efflux and that regulates its root/shoot distribution, has revealed surprising interactions with K+ uptake mechanisms by roots, and proteins of the NHX family are endosomal transporters that play critical roles in … WebThe Na+/Ca2+-K+ exchanger (NCKX) extrudes Ca2+ from cells utilizing both the inward Na+ gradient and the outward K+ gradient. NCKX is thought to operate by a consecutive mechanism in which a cation binding pocket accommodates both Ca2+ and K+ and alternates between inward and outward facing conformations. Here we developed a …
