Background: The effects of allosteric modulators on G protein-coupled receptor trafficking are largely unknown. Results: The allosteric ligand BQCA modulates M1 mAChR arrestin recruitment and receptor trafficking. Conclusion: M1 mAChR trafficking is arrestin- and G protein-dependent and modulated by BQCA. Significance: The impact of allosteric modulators on receptor trafficking needs to be assessed when considering this family of ligands as potential chronic therapies.
