Background: The TGR5 bile acid receptor controls energy balance, inflammation, and digestion, but TGR5 signaling is poorly understood. Results: TGR5 does not interact with ?-arrestins, internalize, or desensitize, but signals from plasma membrane rafts. Conclusion: TGR5 transmits sustained signals close to the cell surface. Significance: Understanding TGR5 signaling will facilitate design of TGR5 agonists for metabolic, inflammatory, and digestive disorders.
