Molecular function

voltage-dependent potassium channel activity involved in ventricular cardiac muscle cell action potential, voltage-gated potassium ion channel activity involved in ventricular cardiac muscle cell action potential, voltage-sensitive potassium channel involved in ventricular cardiac muscle cell action potential

Enables the transmembrane transfer of a potassium ion by a voltage-gated channel through the plasma membrane of a ventricular cardiomyocyte 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.
