Tl(+)-induced μs Gating of Current Indicates Instability of the MaxiK Selectivity Filter as Caused by Ion/Pore Interaction

Patch clamp experiments on single MaxiK channels expressed in HEK293 cells were performed at high temporal resolution (50-kHz filter) in asymmetrical solutions containing 0, 25, 50, or 150 mM Tl(+) on the luminal or cytosolic side with [K(+)] + [Tl(+)] = 150 mM and 150 mM K(+) on the other side.
