The branching reaction leads to the formation of the catalytic step I spliceosome (C complex). Here we report the cryo-electron microscopy structure of the human C complex at an average resolution of 4.1 angstroms. Compared with the C complex, the human complex contains 11 additional proteins. The step I splicing factors CCDC49 and CCDC94 (Cwc25 and Yju2 in , respectively) closely interact with the DEAH-family adenosine triphosphatase/helicase Prp16 and bridge the gap between Prp16 and the active-site RNA elements. These features, together with structural comparison of the human C and C* complexes, provide mechanistic insights into ribonucleoprotein remodeling and allow the proposition of a working mechanism for the C-to-C* transition. 履歴 登録 2017年12月14日 - ヘッダ(付随情報) 公開 2018年8月8日 - マップ公開 2018年8月8日 - 更新 2024年10月23日 - 現状 2024年10月23日 処理サイト : PDBj / 状態 : 公開
