GPCR

Lock and key become flexible

G-protein-coupled receptors (GPCRs) are critically involved in signal transduction. Structural views of several GPCRs have recently been obtained, but the structural principles determining subtype selectivity are still mostly elusive. Now, a combined solid-state NMR and molecular-modeling approach reveals how bradykinin GPCRs distinguish between closely related peptide ligands.
