The reconstituted FL-KvLm channel is voltage gated and rectifies strongly. Currents under voltage clamp of reconstituted FL-KvLm channels in asolectin liposomes evoked by a voltage ramp (A) or at constant negative (B) and positive (C) potentials of 80, 100, and 120 mV. Currents were recorded in symmetrical 200 mM KCl and 5 mM HEPES, pH 7.2.
