Role of the novel endoribonuclease SLFN14 and its disease-causing mutations in ribosomal degradation [ARTICLE]

01-Jul-2018 | Sarah J. Fletcher; Vera P. Pisareva; Abdullah O. Khan; Andrew Tcherepanov; Neil V. Morgan; Andrey V. Pisarev, RNA, 2018

Platelets are anucleate and mostly ribosome-free cells within the bloodstream, derived from megakaryocytes within bone marrow and crucial for cessation of bleeding at sites of injury. Inherited thrombocytopenias are a group of disorders characterized by a low platelet count and are frequently ...


7SL RNA in vertebrate red blood cells [REPORT]

01-Jul-2018 | Gaëlle J.S. Talhouarne; Joseph G. Gall, RNA, 2018

We report that 7SL, the RNA component of the signal recognition particle (SRP), is an abundant noncoding RNA (ncRNA) in mature red blood cells (RBCs) of human, mouse, and the frog Xenopus. 7SL RNA in RBCs is not associated with the canonical proteins of the SRP. Instead, it coimmunoprecipitates ...


Assembly of the small ribosomal subunit in yeast: mechanism and regulation [REVIEW]

01-Jul-2018 | Malik Chaker-Margot, RNA, 2018

The eukaryotic ribosome is made of four intricately folded ribosomal RNAs and 79 proteins. During rapid growth, yeast cells produce an incredible 2000 ribosomes every minute. Ribosome assembly involves more than 200 trans-acting factors, intervening from the transcription of the preribosomal RNA ...


Structure-function analysis of Sua5 protein reveals novel functional motifs required for the biosynthesis of the universal t6A tRNA modification [ARTICLE]

01-Jul-2018 | Adeline Pichard-Kostuch; Wenhua Zhang; Dominique Liger; Marie-Claire Daugeron; Juliette Létoquart; Ines Li de la Sie ..., RNA, 2018

N6-threonyl-carbamoyl adenosine (t6A) is a universal tRNA modification found at position 37, next to the anticodon, in almost all tRNAs decoding ANN codons (where N = A, U, G, or C). t6A stabilizes the codon–anticodon interaction and hence promotes translation fidelity. The first step of the ...


Simultaneous sequencing of coding and noncoding RNA reveals a human transcriptome dominated by a small number of highly expressed noncoding genes [ARTICLE]

01-Jul-2018 | Vincent Boivin; Gabrielle Deschamps-Francoeur; Sonia Couture; Ryan M. Nottingham; Philia Bouchard-Bourelle; Alan M. ..., RNA, 2018

Comparing the abundance of one RNA molecule to another is crucial for understanding cellular functions but most sequencing techniques can target only specific subsets of RNA. In this study, we used a new fragmented ribodepleted TGIRT sequencing method that uses a thermostable group II intron ...


Highly efficient in vitro translation of authentic affinity-purified messenger ribonucleoprotein complexes [METHOD]

01-Jul-2018 | Sarah E. Fritz; Nazmul Haque; J. Robert Hogg, RNA, 2018

Cell-free systems are widely used to study mechanisms and regulation of translation, but the use of in vitro transcribed (IVT) mRNAs as translation substrates limits their efficiency and utility. Here, we present an approach for in vitro translation of messenger ribonucleoprotein (mRNP) complexes ...


MicroRNA-focused CRISPR-Cas9 library screen reveals fitness-associated miRNAs [ARTICLE]

01-Jul-2018 | Jessica S. Kurata; Ren-Jang Lin, RNA, 2018

MicroRNAs (miRNAs) are post-transcriptional gene regulators that play important roles in the control of cell fitness, differentiation, and development. The CRISPR-Cas9 gene-editing system is composed of the Cas9 nuclease in complex with a single guide RNA (sgRNA) and directs DNA cleavage at a ...


SRSF3 recruits DROSHA to the basal junction of primary microRNAs [REPORT]

01-Jul-2018 | Kijun Kim; Trung Duc Nguyen; Shaohua Li; Tuan Anh Nguyen, RNA, 2018

The Microprocessor complex, consisting of an RNase III DROSHA and the DGCR8 dimer, cleaves primary microRNA transcripts (pri-miRNAs) to initiate microRNA (miRNA) maturation. Pri-miRNAs are stem–loop RNAs, and ~79% of them contain at least one of the three major and conserved RNA motifs, UG, UGU, ...


siRNAs and piRNAs collaborate for transposon control in the two-spotted spider mite [REPORT]

01-Jul-2018 | Mosharrof Mondal; Kody Mansfield; Alex Flynt, RNA, 2018

RNAi has revolutionized genetic research, and is being commercialized as an insect pest control technology. Mechanisms exploited for this purpose are antiviral and therefore rapidly evolving. Ideally, RNAi will also be used for noninsect pests; however, differences in RNAi biology make this ...


Hydrogen peroxide is a neuronal alarmin that triggers specific RNAs, local translation of Annexin A2, and cytoskeletal remodeling in Schwann cells [ARTICLE]

01-Jul-2018 | Samuele Negro; Marco Stazi; Marta Marchioretto; Toma Tebaldi; Umberto Rodella; Elisa Duregotti; Volker Gerke; Alessa ..., RNA, 2018

Schwann cells are key players in neuro-regeneration: They sense "alarm" signals released by degenerating nerve terminals and differentiate toward a proregenerative phenotype, with phagocytosis of nerve debris and nerve guidance. At the murine neuromuscular junction, hydrogen peroxide (H2O2) is a ...
