引用ジャーナル : Sci Adv / 年 : 2020タイトル : Cryo-EM structure of the Hedgehog release protein Dispatched.著者 : Fabien Cannac / Chao Qi / Julia Falschlunger / George Hausmann / Konrad Basler / Volodymyr M Korkhov / 要旨 : The Hedgehog (Hh) signaling pathway controls embryonic development and adult tissue homeostasis in multicellular organisms. In , the pathway is primed by secretion of a dually lipid-modified ... The Hedgehog (Hh) signaling pathway controls embryonic development and adult tissue homeostasis in multicellular organisms. In , the pathway is primed by secretion of a dually lipid-modified morphogen, Hh, a process dependent on a membrane-integral protein Dispatched. Although Dispatched is a critical component of the pathway, the structural basis of its activity has, so far, not been described. Here, we describe a cryo-electron microscopy structure of the Dispatched at 3.2-Å resolution. The ectodomains of Dispatched adopt an open conformation suggestive of a receptor-chaperone role. A three-dimensional reconstruction of Dispatched bound to Hh confirms the ability of Dispatched to bind Hh but using a unique mode distinct from those previously observed in structures of Hh complexes. The structure may represent the state of the complex that precedes shedding of Hh from the surface of the morphogen-releasing cell. 履歴 登録 2019年11月7日 - ヘッダ(付随情報) 公開 2020年6月3日 - マップ公開 2020年6月3日 - 更新 2024年10月23日 - 現状 2024年10月23日 処理サイト : PDBe / 状態 : 公開
