Schematic showing the subunit composition of the N-type calcium channel. A: The channel complex consists of pore-forming α1-subunit that also contains the voltage sensor and is the target of pharmacological agents, a β-subunit that modulates the biophysical and second-messenger-dependent properties of the α1-subunit, and an α2δ-subunit. B: Amino acid identity comparisons of the ten calcium channel α1-subunit genes found in the mammalian genome.
