Na(+) Block and Permeation in a K(+) Channel of Known Structure
The effects of intracellular Na(+) were studied on K(+) and Rb(+) currents through single KcsA channels. At low voltage, Na(+) produces voltage-dependent block, which becomes relieved at high voltage by a “punchthrough” mechanism representing Na(+) escaping from its blocking site through the selecti...
