引用ジャーナル : Science / 年 : 2024タイトル : Molecular mechanism of actin filament elongation by formins.著者 : Wout Oosterheert / Micaela Boiero Sanders / Johanna Funk / Daniel Prumbaum / Stefan Raunser / Peter Bieling / 要旨 : Formins control the assembly of actin filaments (F-actin) that drive cell morphogenesis and motility in eukaryotes. However, their molecular interaction with F-actin and their mechanism of action ... Formins control the assembly of actin filaments (F-actin) that drive cell morphogenesis and motility in eukaryotes. However, their molecular interaction with F-actin and their mechanism of action remain unclear. In this work, we present high-resolution cryo-electron microscopy structures of F-actin barbed ends bound by three distinct formins, revealing a common asymmetric formin conformation imposed by the filament. Formation of new intersubunit contacts during actin polymerization sterically displaces formin and triggers its translocation. This "undock-and-lock" mechanism explains how actin-filament growth is coordinated with formin movement. Filament elongation speeds are controlled by the positioning and stability of actin-formin interfaces, which distinguish fast and slow formins. Furthermore, we provide a structure of the actin-formin-profilin ring complex, which resolves how profilin is rapidly released from the barbed end during filament elongation. 履歴 登録 2024年1月29日 - ヘッダ(付随情報) 公開 2024年4月10日 - マップ公開 2024年4月10日 - 更新 2024年4月24日 - 現状 2024年4月24日 処理サイト : PDBe / 状態 : 公開
