The P-type calcium channel is a type of voltage-dependent calcium channel. Similar to many other high-voltage-gated calcium channels the α1 subunit determines most of the channel’s properties. The ‘P’ signifies cerebellar Purkinje cells referring to the channels initial site of discovery. P-type calcium channels play a similar role to the N-type calcium channel in neurotransmitter release at the presynaptic terminal and in neuronal integration in many neuronal types.
