Term Name:	voltage-gated potassium channel activity involved in SA node cell action potential depolarization
Synonyms:	voltage-gated potassium channel activity involved in SAN cell action potential depolarization, voltage-gated potassium channel activity involved in sinoatrial node cell action potential depolarization, voltage-gated potassium channel activity involved in sinus node cell action potential depolarization
Definition:	Enables the transmembrane transfer of a potassium ion by a voltage-gated channel through the plasma membrane of an SA node cardiac muscle cell contributing to the depolarization 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.
