voltage-gated sodium channel activity involved in SA node cell action potential (GO:0086063)
Annotations: Rat: (1) Mouse: (1) Human: (1) Chinchilla: (1) Bonobo: (1) Dog: (1) Squirrel: (1)
Parent Terms Term With Siblings Child Terms
voltage-gated sodium channel activity involved in AV node cell action potential  
voltage-gated sodium channel activity involved in bundle of His cell action potential  
voltage-gated sodium channel activity involved in Purkinje myocyte action potential  
voltage-gated sodium channel activity involved in SA node cell action potential  
Enables the transmembrane transfer of a sodium 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.
