Title: Crystal structure of the human NK 1 tachykinin receptor

Abstract

The NK 1 tachykinin G-protein–coupled receptor (GPCR) binds substance P, the first neuropeptide to be discovered in mammals. Through activation of NK 1R, substance P modulates a wide variety of physiological and disease processes including nociception, inflammation, and depression. Human NK 1R (hNK 1R) modulators have shown promise in clinical trials for migraine, depression, and emesis. However, the only currently approved drugs targeting hNK 1R are inhibitors for chemotherapy-induced nausea and vomiting (CINV). To better understand the molecular basis of ligand recognition and selectivity, we solved the crystal structure of hNK 1R bound to the inhibitor L760735, a close analog of the drug aprepitant. Our crystal structure reveals the basis for antagonist interaction in the deep and narrow orthosteric pocket of the receptor. We used our structure as a template for computational docking and molecular-dynamics simulations to dissect the energetic importance of binding pocket interactions and model the binding of aprepitant. Furthermore, the structure of hNK 1R is a valuable tool in the further development of tachykinin receptor modulators for multiple clinical applications.
