Fig. 2. — TdHKT1;4-1 and TdHKT1;4-2 function as monovalent cation transporters with a strong preference for Na⁺ in Xenopus oocytes. Bath solutions contained the standard background supplemented with NaCl, KCl, RbCl, CsCl, or LiCl, at 3mM. The voltage-clamp protocol consisted of 12 pulses of 1 s, with a voltage increment of 15 mV between pulses. (A) Currents from control (H₂O-injected) oocytes plotted against applied voltages. (B, C) Currents flowing through TdHKT1;4-1 (B) and TdHKT1;4-2 (C) transporters versus applied voltages. Data are means±standard error (SE) (n=4) and are representative of five experiments performed on different oocyte batches.
