引用ジャーナル : Mol Cell / 年 : 2022タイトル : Structure and regulation of the nuclear exosome targeting complex guides RNA substrates to the exosome.著者 : Piotr Gerlach / William Garland / Mahesh Lingaraju / Anna Salerno-Kochan / Fabien Bonneau / Jérôme Basquin / Torben Heick Jensen / Elena Conti / 要旨 : In mammalian cells, spurious transcription results in a vast repertoire of unproductive non-coding RNAs, whose deleterious accumulation is prevented by rapid decay. The nuclear exosome targeting ... In mammalian cells, spurious transcription results in a vast repertoire of unproductive non-coding RNAs, whose deleterious accumulation is prevented by rapid decay. The nuclear exosome targeting (NEXT) complex plays a central role in directing non-functional transcripts to exosome-mediated degradation, but the structural and molecular mechanisms remain enigmatic. Here, we elucidated the architecture of the human NEXT complex, showing that it exists as a dimer of MTR4-ZCCHC8-RBM7 heterotrimers. Dimerization preconfigures the major MTR4-binding region of ZCCHC8 and arranges the two MTR4 helicases opposite to each other, with each protomer able to function on many types of RNAs. In the inactive state of the complex, the 3' end of an RNA substrate is enclosed in the MTR4 helicase channel by a ZCCHC8 C-terminal gatekeeping domain. The architecture of a NEXT-exosome assembly points to the molecular and regulatory mechanisms with which the NEXT complex guides RNA substrates to the exosome. 履歴 登録 2022年3月7日 - ヘッダ(付随情報) 公開 2022年6月22日 - マップ公開 2022年6月22日 - 更新 2023年12月13日 - 現状 2023年12月13日 処理サイト : PDBe / 状態 : 公開
