引用ジャーナル : Cell Res / 年 : 2018タイトル : Structure of the human activated spliceosome in three conformational states.著者 : Xiaofeng Zhang / Chuangye Yan / Xiechao Zhan / Lijia Li / Jianlin Lei / Yigong Shi / 要旨 : During each cycle of pre-mRNA splicing, the pre-catalytic spliceosome (B complex) is converted into the activated spliceosome (B complex), which has a well-formed active site but cannot proceed to ... During each cycle of pre-mRNA splicing, the pre-catalytic spliceosome (B complex) is converted into the activated spliceosome (B complex), which has a well-formed active site but cannot proceed to the branching reaction. Here, we present the cryo-EM structure of the human B complex in three distinct conformational states. The EM map allows atomic modeling of nearly all protein components of the U2 small nuclear ribonucleoprotein (snRNP), including three of the SF3a complex and seven of the SF3b complex. The structure of the human B complex contains 52 proteins, U2, U5, and U6 small nuclear RNA (snRNA), and a pre-mRNA. Three distinct conformations have been captured, representing the early, mature, and late states of the human B complex. These complexes differ in the orientation of the Switch loop of Prp8, the splicing factors RNF113A and NY-CO-10, and most components of the NineTeen complex (NTC) and the NTC-related complex. Analysis of these three complexes and comparison with the B and C complexes reveal an ordered flux of components in the B-to-B and the B-to-B transitions, which ultimately prime the active site for the branching reaction. 履歴 登録 2018年1月17日 - ヘッダ(付随情報) 公開 2018年9月19日 - マップ公開 2018年9月19日 - 更新 2020年10月14日 - 現状 2020年10月14日 処理サイト : PDBj / 状態 : 公開
