voltage-gated potassium channel activity involved in SA node cell action potential repolarization

Term ID

GO:0086090

Synonyms

• voltage-gated potassium channel activity involved in SAN cell action potential
• voltage-gated potassium channel activity involved in sinoatrial node cell action potential
• voltage-gated potassium channel activity involved in sinus node cell action potential

Definition

Enables the transmembrane transfer of a potassium ion by a voltage-gated channel through the plasma membrane of an SA node 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.
