Alkali cation selectivity of the wheat root high-affinity potassium transporter HKT1

High-Affinity Potassium Uptake Transporter from Higher Plants

Alkali Cation Selectivity and Fixation by Clay Minerals

-Two variables must be considered when calculating exchange free energies (AG~ for 2:1 clays: (1) anionic field strength, as expressed by equivalent anionic radius (ra), and (2) interlayer water content, as expressed by interlayer molality. For smectites that are in a state of high hydration, interlayer molality is determined by the cations undergoing exchange. Thus AG~ for an exchanging cation...

The human organic cation transporter OCT1 mediates high affinity uptake of the anticancer drug daunorubicin

Anthracyclines such as daunorubicin are anticancer agents that are transported into cells, and exert cytotoxicity by blocking DNA metabolism. Although there is evidence for active uptake of anthracyclines into cells, the specific transporter involved in this process has not been identified. Using the high-grade serous ovarian cancer cell line TOV2223G, we show that OCT1 mediated the high affini...

The rice monovalent cation transporter OsHKT2;4: revisited ionic selectivity.

The family of plant membrane transporters named HKT (for high-affinity K(+) transporters) can be subdivided into subfamilies 1 and 2, which, respectively, comprise Na(+)-selective transporters and transporters able to function as Na(+)-K(+) symporters, at least when expressed in yeast (Saccharomyces cerevisiae) or Xenopus oocytes. Surprisingly, a subfamily 2 member from rice (Oryza sativa), OsH...

Running Head: the Rice Oshkt2;4 Monovalent Cation Transporter the Rice Monovalent Cation Transporter Oshkt2;4: Revisited Ionic Selectivity

The family of plant membrane transporters named HKT (for High-affinity K + Transporters) can be subdivided into sub-families 1 and 2, which respectively comprise Na +-selective transporters and transporters able to function as Na +-K + symporters, at least when expressed in yeast or Xenopus oocytes. Surprisingly, a subfamily 2 member from rice (Oryza sativa),
