Effect of pH on other transporters. Current traces were recorded from oocytes injected with cRNA for GABA (GAT1) (A), Na⁺/glucose (SGLT) (B), dopamine (DAT) (C), or glycine (GLYT1) (D) transporters, or from an uninjected oocyte from the same batch (E). Holding potential, −40 mV. Base solution, NMDG Ringer’s solution, pH 7.5 (left panelsin A–D, and E), or Na⁺Ringer’s solution, pH 7.5 (right panels inA–D). Concentrations of organic substrates wereGABA, 100 μm; glucose (Gluc), 1 mm; dopamine (Dop), 10 μm; glycine (Glyc), 100 μm.
