Kv1.5 is a potassium channel that is involved in restoring the resting membrane potential after depolarisation. Kv1.5 is not a classic cannabinoid receptor but its activity is modulated by cannabinoids. Since cannabinoids have a physiological effect on Kv1.5 it is effectively a cannabinoid receptor.
