The regulation and functions of the nuclear RNA exosome complex [PDF]

open access: yesNature Reviews Molecular Cell Biology, 2016
The RNA exosome complex is the most versatile RNA-degradation machine in eukaryotes. The exosome has a central role in several aspects of RNA biogenesis, including RNA maturation and surveillance. Moreover, it is emerging as an important player in regulating the expression levels of specific mRNAs in response to environmental cues and during cell ...

APE1 interacts with the nuclear exosome complex protein MTR4 and is involved in cisplatin‐ and 5‐fluorouracil‐induced RNA damage response

The FEBS Journal, 2022
The nuclear RNA surveillance mechanism is essential for cancer cell survival and is ensured by the RNA nuclear exosome including some co‐factors, such as the RNA helicase MTR4. Recent studies suggest an involvement of DNA repair proteins such as apurinic/

NMR studies of the archaeal exosome complex

, 2016
This study is about structural studies of the exosome from Sulfolobus solfataricus. It includes dynamics analysis (by using Nuclear Magnetic Resonance) of the complex in absence and in presence of RNA. Additional biochemical experiments (degradation assays, fluorescence anisotropy) allowed further description of the interaction exosome-RNA.

RNA degradation paths in a 12-subunit nuclear exosome complex

Nature, 2015
The eukaryotic exosome is a conserved RNA-degrading complex that functions in RNA surveillance, turnover and processing. How the same machinery can either completely degrade or precisely trim RNA substrates has long remained unexplained. Here we report the crystal structures of a yeast nuclear exosome containing the 9-subunit core, the 3'-5' RNases ...
