引用ジャーナル : Sci Adv / 年 : 2025タイトル : Mechanism of D-type cyclin recognition by the AMBRA1 E3 ligase receptor.著者 : Yang Wang / Ming Liu / Shan Wang / Xinyi Mai / Xi Wang / Fei Teng / Tianrui Lyu / Ming-Yuan Su / Goran Stjepanovic / 要旨 : AMBRA1 is a tumor suppressor protein that functions as a substrate receptor in the ubiquitin conjugation system and regulates the stability of D-type cyclins and cell proliferation. Here, we present ... AMBRA1 is a tumor suppressor protein that functions as a substrate receptor in the ubiquitin conjugation system and regulates the stability of D-type cyclins and cell proliferation. Here, we present the cryo-EM structure of cyclin D1-bound AMBRA1-DDB1 complex at 3.55-Å resolution. The structure reveals a substrate interaction surface on the AMBRA1 WD40 domain that specifically binds to the C-terminal region of D-type cyclins. This interaction is dependent on the phosphorylation of Thr residue in the C-terminal phosphodegron site of D-type cyclins. The phosphodegron motif folds into a turn-like conformation, followed by a 3 helix that promotes its assembly with AMBRA1. In addition, we show that AMBRA1 mutants, which are defective in cyclin D1 binding, lead to cyclin D1 accumulation and DNA damage. Understanding the AMBRA1-D-type cyclin structure enhances the knowledge of the molecular mechanisms that govern the cell cycle control and may lead to potential therapeutic approaches for cancers linked to abnormal cyclin D activity. 履歴 登録 2024年7月23日 - ヘッダ(付随情報) 公開 2025年4月23日 - マップ公開 2025年4月23日 - 更新 2025年7月16日 - 現状 2025年7月16日 処理サイト : PDBc / 状態 : 公開
