voltage-gated potassium channel activity involved in cardiac muscle cell action potential repolarization
Go to external page http://purl.obolibrary.org/obo/GO_0086008
Enables the transmembrane transfer of a potassium ion by a voltage-gated channel through the plasma membrane of a cardiac muscle 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. [ GOC:BHF GOC:mtg_cardiac_conduct_nov11 ]
