The Voltage Sensor in Voltage-Dependent Ion Channels [PDF]

Physiological Reviews, 2000
In voltage-dependent Na, K, or Ca channels, the probability of opening is modified by the membrane potential. This is achieved through a voltage sensor that detects the voltage and transfers its energy to the pore to control its gate. We present here the theoretical basis of the energy coupling between the electric field and the voltage, which allows ...
