Cav2.1 is a calcium channel of the P/Q type that is central to many brain processes, including learning and memory. Cav2.1 is not a classic cannabinoid receptor but its activity is modulated by cannabinoids. Since cannabinoids have a physiological effect on Cav2.1 it is effectively a cannabinoid receptor.
