voltage-gated potassium channel activity involved in bundle of His cell action potential repolarization
voltage-gated potassium channel activity involved in bundle of his cell action potential repolarization
Enables the transmembrane transfer of a potassium ion by a voltage-gated channel through the plasma membrane of a bundle of His cell contributing to the repolarization phase of an action potential. A voltage-gated channel is a channel whose open state is dependent on the voltage across the membrane in which it is embedded.
