• Citation: Journal: Science / Year: 2018; Title: Structure of a human catalytic step I spliceosome.; Authors: Xiechao Zhan / Chuangye Yan / Xiaofeng Zhang / Jianlin Lei / Yigong Shi / ; Abstract: Splicing by the spliceosome involves branching and exon ligation. 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.
