引用ジャーナル : Nat Struct Mol Biol / 年 : 2022タイトル : Structural basis of an endocytic checkpoint that primes the AP2 clathrin adaptor for cargo internalization.著者 : Edward A Partlow / Kevin S Cannon / Gunther Hollopeter / Richard W Baker / 要旨 : Clathrin-mediated endocytosis (CME) is the main route of internalization from the plasma membrane. It is known that the heterotetrameric AP2 clathrin adaptor must open to simultaneously engage ... Clathrin-mediated endocytosis (CME) is the main route of internalization from the plasma membrane. It is known that the heterotetrameric AP2 clathrin adaptor must open to simultaneously engage membrane and endocytic cargo, yet it is unclear how transmembrane cargos are captured to catalyze CME. Using cryogenic-electron microscopy, we discover a new way in which mouse AP2 can reorganize to expose membrane- and cargo-binding pockets, which is not observed in clathrin-coated structures. Instead, it is stimulated by endocytic pioneer proteins called muniscins, which do not enter vesicles. Muniscin-engaged AP2 is primed to rearrange into the vesicle-competent conformation on binding the tyrosine cargo internalization motif (YxxΦ). We propose adaptor priming as a checkpoint to ensure cargo internalization. 履歴 登録 2021年8月19日 - ヘッダ(付随情報) 公開 2022年3月30日 - マップ公開 2022年3月30日 - 更新 2024年6月5日 - 現状 2024年6月5日 処理サイト : RCSB / 状態 : 公開
