Cav3.2 is a calcium channel of the T-type that is involved in many processes in the brain and other tissues. Contrary to other calcium channels Cav3.2 is activated by relatively low/negative voltages. Cav3.2 is not a classic cannabinoid receptor but its activity is modulated by cannabinoids. Since cannabinoids have a physiological effect on Cav3.2 it is effectively a cannabinoid receptor.
