PAMs permit enhancement without replicating the liabilities of orthosteric agonists. Endogenous ligands remain part of the signaling equation, preserving physiological patterning. Efficacy is not a molecule-only attribute—it's a joint property of ligand and system. High-coupled systems inflate apparent efficacy; low-coupled systems expose its limits. Dr. One carries broad off-target risk; the other behaves more like a high-affinity ligand with slow dissociation

GPCR signaling wasn’t linear. It wasn’t clean. shaped his partnership with JB, the chemist who would eventually help his lab visualize receptors in living They think in functional groups, fluorophores, linkers, and binding pockets. Instead of forcing antibodies to do what they weren’t built for, JB’s group engineered fluorescent ligands The signaling didn’t line up. The knockout behaved differently than expected.
