N-type calcium channel

The N-type calcium channel is a type of voltage-dependent calcium channel. As with other sub-types of voltage-gated calcium channel, the a₁ subunit forms the pore through which calcium enters the cell and determines most of the channel's properties. The a₁ subunit is also known as the calcium channel, voltage-dependent, N type, alpha 1B subunit (CACNA1B) or Ca_v2.2 which in humans is encoded by the CACNA1B gene.
