引用ジャーナル : Proc Natl Acad Sci U S A / 年 : 2017タイトル : Cryo-EM structure of the DNA-PK holoenzyme.著者 : Humayun Sharif / Yang Li / Yuanchen Dong / Liyi Dong / Wei Li Wang / Youdong Mao / Hao Wu / 要旨 : DNA-dependent protein kinase (DNA-PK) is a large protein complex central to the nonhomologous end joining (NHEJ) DNA-repair pathway. It comprises the DNA-PK catalytic subunit (DNA-PKcs) and the ... DNA-dependent protein kinase (DNA-PK) is a large protein complex central to the nonhomologous end joining (NHEJ) DNA-repair pathway. It comprises the DNA-PK catalytic subunit (DNA-PKcs) and the heterodimer of DNA-binding proteins Ku70 and Ku80. Here, we report the cryo-electron microscopy (cryo-EM) structures of human DNA-PKcs at 4.4-Å resolution and the DNA-PK holoenzyme at 5.8-Å resolution. The DNA-PKcs structure contains three distinct segments: the N-terminal region with an arm and a bridge, the circular cradle, and the head that includes the kinase domain. Two perpendicular apertures exist in the structure, which are sufficiently large for the passage of dsDNA. The DNA-PK holoenzyme cryo-EM map reveals density for the C-terminal globular domain of Ku80 that interacts with the arm of DNA-PKcs. The Ku80-binding site is adjacent to the previously identified density for the DNA-binding region of the Ku70/Ku80 complex, suggesting concerted DNA interaction by DNA-PKcs and the Ku complex. 履歴 登録 2017年6月4日 - ヘッダ(付随情報) 公開 2017年7月19日 - マップ公開 2017年7月19日 - 更新 2020年11月25日 - 現状 2020年11月25日 処理サイト : RCSB / 状態 : 公開
