Authors: Shicheng Zhang / He Chen / Chengwei Zhang / Ying Yang / Petr Popov / Jing Liu / Brian E Krumm / Can Cao / Kuglae Kim / Yan Xiong / Vsevolod Katritch / Brian K Shoichet / Jian Jin / Jonathan ...Authors: Shicheng Zhang / He Chen / Chengwei Zhang / Ying Yang / Petr Popov / Jing Liu / Brian E Krumm / Can Cao / Kuglae Kim / Yan Xiong / Vsevolod Katritch / Brian K Shoichet / Jian Jin / Jonathan F Fay / Bryan L Roth / Abstract: Serotonin receptors are important targets for established therapeutics and drug development as they are expressed throughout the human body and play key roles in cell signaling. There are 12 ...Serotonin receptors are important targets for established therapeutics and drug development as they are expressed throughout the human body and play key roles in cell signaling. There are 12 serotonergic G protein-coupled receptor members encoded in the human genome, of which the 5-hydroxytryptamine (5-HT) receptor (5-HTR) is the least understood and lacks selective tool compounds. Here, we report four high-resolution (2.73-2.80 Å) structures of human 5-HTRs, including an inactive state structure bound to an antagonist AS2674723 by crystallization and active state structures bound to a partial agonist lisuride and two full agonists, 5-carboxamidotryptamine (5-CT) and methylergometrine, by cryo-EM. Leveraging the new structures, we developed a highly selective and potent antagonist for 5-HTR. Collectively, these findings both enhance our understanding of this enigmatic receptor and provide a roadmap for structure-based drug discovery for 5-HTR. | |||||||||
