obsolete voltage-gated calcium channel activity involved in Purkinje myocyte cell action potential (obsolete GO:0086058)
OBSOLETE. Enables the transmembrane transfer of a calcium ion by a voltage-gated channel across the plasma membrane of an Purkinje myocyte cell that contributes 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.
