Structures of active-state orexin receptor 2 rationalize peptide and small-molecule agonist recognition and receptor activation

Agonists of the orexin receptor 2 (OX2R) show promise in the treatment of narcolepsy. Cryo-EM structures of active-state OX2R bound to an endogenous peptide agonist and a small-molecule agonist suggest a molecular mechanism that rationalizes both receptor activation and inhibition.
