The yeast C/D box snoRNA U14 adopts a "weak" K-turn like conformation recognized by the Snu13 core protein in solution

Benjamin Marcel Daniel Rothé

Non-coding RNAs associate with proteins to form ribonucleoproteins (RNPs), such as ribosome, box C/D snoRNPs, H/ACA snoRNPs, ribonuclease P, telomerase and spliceosome to ensure cell viability. The assembly of these RNA-protein complexes relies on the abil ...

Beyond silence : a functional and evolutionary study of KRAB zinc finger proteins

Pierre-Yves Joseph Laurent Helleboid

Transposable elements (TEs) are genetic units capable of spreading within the genomes of their host. TEs contribute a readily recognizable 45% of the human DNA, reflecting in part their co-option for some as source of protein-coding sequences, for others a ...

Lossy compression of quality scores in differential gene expression: A first assessment and impact analysis

Ana Angelica Hernandez Lopez

High-throughput sequencing of RNA molecules has enabled the quantitative analysis of gene expression at the expense of storage space and processing power. To alleviate these prob- lems, lossy compression methods of the quality scores associated to RNA sequ ...

The Structure of the Protonated Serine Octamer

Ursula Röthlisberger, Thomas Rizzo, Stephan Warnke, Valeriu Scutelnic, Aurelien Stephen Arnaud Gregor

The amino acid serine has long been known to form a protonated “magic-number” cluster containing eight monomer units that shows an unusually high abundance in mass spectra and has a remarkable homochiral preference. Despite many experimental and theoretica ...

Development of Site-Specific Mg2+-RNA Force Field Parameters: A Dream or Reality? Guidelines from Combined Molecular Dynamics and Quantum Mechanics Simulations

Ursula Röthlisberger, Giulia Palermo

The vital contribution of Mg2+ ions to RNA biology is challenging to dissect at the experimental level. This calls for the integrative support of atomistic simulations, which at the classical level are plagued by limited accuracy. Indeed, force fields intr ...

A practical qPCR approach to detect TERRA, the elusive telomeric repeat-containing RNA

Joachim Lingner, Marianna Feretzaki

Telomeres, the heterochromatic structures that protect the ends of the chromosomes, are transcribed into a class of long non-coding RNAs, telomeric repeat-containing RNAs (TERRA), whose transcriptional regulation and functions are not well understood. The ...

Placeholder factors in ribosome biogenesis: please, pave my way

The synthesis of cytoplasmic eukaryotic ribosomes is an extraordinarily energy-demanding cellular activity that occurs progressively from the nucleolus to the cytoplasm. In the nucleolus, precursor rRNAs associate with a myriad of trans-acting factors and ...

The effects of mitochondrial- and histone stress on the C. elegans transcriptome

Johan Auwerx, Maroun Bou Sleiman, Pedro Moral Quiros, Olli Juhani Matilainen

The aim of this study was to explore whether mitochondrial- and histone stress cause any common changes in global gene expression. For this experiment, we performed RNA sequencing from control RNAi, cco-1 RNAi (mitochondrial stress) and his-3 RNAi (histone ...

α-Oxo-Ketenimines from Isocyanides and α-Haloketones: Synthesis and Divergent Reactivity

Jieping Zhu, Qian Wang, Mathias Mamboury

The palladium-catalyzed reaction of a-haloketones with isocyanides afforded -oxo-ketenimines through alpha-hydride elimination of the beta-oxo-imidoyl palladium intermediates. Reaction of these relatively stable alpha-oxo ketenimines with nucleophiles suc ...
