Novel mRNA-silencing bodies at the synapse: A never-ending story
Communicative & Integrative Biology, 2016 Several cellular responses depend on translational regulation and in most cases, this involves the formation of cytoplasmic granules that contain repressed mRNAs.

Cutoff Suppresses RNA Polymerase II Termination to Ensure Expression of piRNA Precursors [PDF]
, 2016 Small non-coding RNAs called piRNAs serve as guides for an adaptable immune system that represses transposable elements in germ cells of Metazoa. In Drosophila the RDC complex, composed of Rhino, Deadlock and Cutoff (Cuff) bind chromatin of dual-strand ...

Exoribonuclease-Resistant RNAs Exist within both Coding and Noncoding Subgenomic RNAs
mBio, 2018 Many viruses produce protein-coding and noncoding subgenomic RNAs (sgRNAs) that are critical for infection. A recently discovered pathway for viral sgRNA production uses exoribonuclease-resistant RNAs (xrRNAs), discrete folded RNA elements that block the

40S ribosome biogenesis co-factors are essential for gametophyte and embryo development [PDF]
, 2013 Ribosome biogenesis is well described in Saccharomyces cerevisiae. In contrast only very little information is available on this pathway in plants. This study presents the characterization of five putative protein co-factors of ribosome biogenesis in ...

Regulation of RNA decay and cellular function by 3′-5′ exoribonuclease DIS3L2
RNA Biology, 2019 DIS3L2, in which mutations have been linked to Perlman syndrome, is an RNA-binding protein with 3′-5′ exoribonuclease activity. It contains two CSD domains and one S1 domain, all of which are RNA-binding domains, and one RNB domain that is responsible ...

A short splicing isoform of HBS1L links the cytoplasmic exosome and SKI complexes in humans. [PDF]
, 2016 The exosome complex is a major eukaryotic exoribonuclease that requires the SKI complex for its activity in the cytoplasm. In yeast, the Ski7 protein links both complexes, whereas a functional equivalent of the Ski7 has remained unknown in the human ...
