label_lc: voltage-gated calcium channel activity involved in bundle of his cell action potential
description: "Enables the transmembrane transfer of a calcium ion by a voltage-gated channel across the plasma membrane of a bundle of His cardiac muscle 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."
