Potassium-dependent Changes in the Conformation of the Kv2.1 Potassium Channel Pore
The voltage-gated K(+) channel, Kv2.1, conducts Na(+) in the absence of K(+). External tetraethylammonium (TEA(o)) blocks K(+) currents through Kv2.1 with an IC(50) of 5 mM, but is completely without effect in the absence of K(+). TEA(o) block can be titrated back upon addition of low [K(+)]. This s...
