The export of mRNA from nucleus to cytoplasm requires the conserved and essential transcription and export (TREX) complex (THO-UAP56/DDX39B-ALYREF). TREX selectively binds mRNA maturation marks and licenses mRNA for nuclear export by loading the export factor NXF1-NXT1. How TREX integrates these marks and achieves high selectivity for mature mRNA is poorly understood. Here, we report the cryo-electron microscopy structure of the human THO-UAP56/DDX39B complex at 3.3 Å resolution. The seven-subunit THO-UAP56/DDX39B complex multimerizes into a 28-subunit tetrameric assembly, suggesting that selective recognition of mature mRNA is facilitated by the simultaneous sensing of multiple, spatially distant mRNA regions and maturation marks. Two UAP56/DDX39B RNA helicases are juxtaposed at each end of the tetramer, which would allow one bivalent ALYREF protein to bridge adjacent helicases and regulate the TREX-mRNA interaction. Our structural and biochemical results suggest a conserved model for TREX complex function that depends on multivalent interactions between proteins and mRNA. 履歴 登録 2020年10月17日 - ヘッダ(付随情報) 公開 2020年12月16日 - マップ公開 2020年12月16日 - 更新 2024年5月1日 - 現状 2024年5月1日 処理サイト : PDBe / 状態 : 公開
