- Targeting Intracellular Allosteric Sites in GPCRs
Biased allosteric mechanisms Allosteric sites can differentially modulate G-protein and β-arrestin coupling G-protein-biased allosteric antagonists are under investigation for several GPCRs, including CCR2, CCR7 Allosteric agonists binding to intracellular sites can also promote G-protein signaling.
