Measuring Endocannabinoid System Interaction with Biomembranes.

Understanding the correct interaction among the different components of the endocannabinoid (eCB) system is fundamental for a proper assessment of the function of eCBs as signaling molecules. The knowledge of how the membrane environment modulates the intracellular trafficking of the eCB system and its interacting proteins holds a huge potential in unraveling new mechanisms of its modulation. This chapter deals with the application of fluorescence resonance energy transfer technique to measure the binding affinity of eCB proteins to model membranes (i.
