- GPCRs are not simple on-off switches: deep dive into GPCR-ligand interactions
An alternative and promising approach is allosteric modulation. Over the past decade, there has been a notable growth in the discovery of allosteric modulators for GPCRs which possess the capability to modulate and fine-tune the affinity and/or efficacy of orthosteric ligands Allosteric modulators that do not exhibit agonistic properties remain inactive in the absence of endogenous In this context, allosteric modulators exhibiting constrained positive or negative cooperativity are
