K-ATP is a potassium channel that is sensitive to ATP and therefore to cellular energy levels. K-ATP functions to control cellular energy levels. K-ATP is not a classic cannabinoid receptor but its activity is modulated by cannabinoids. Since cannabinoids have a physiological effect on K-ATP it is effectively a cannabinoid receptor.
