NvShak1-6 express a functionally diverse set of Shaker currents in <i>Xenopus</i> oocytes.

<p>Families of outward K⁺ currents recorded from excised inside-out patches taken from oocytes expressing NvShak1-6 are shown in a–f. Currents were recorded in response to 100 ms depolarizations ranging from −60 to +60 mV in 10 mV increments from a holding potential of −100 mV. Scale bars are given for time and current amplitude and arrows mark the current elicited at 0 mV. Note this is the first step with significant current for NvShak2 and NvShak3. K⁺ concentration for these recordings was 2 mM in the pipette (extracellular) and 140 mM in the bath (intracellular).
