voltage-gated sodium channel activity
voltage-gated sodium channel activity involved in cardiac muscle cell action potential
GO:0086006
2011-11-10T08:34:49Z
Enables the transmembrane transfer of a sodium ion by a voltage-gated channel through the plasma membrane of a 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.
