IGM, Univ Paris Sud, UMR 8621, Orsay, F 91405, France
BMC Mol Biol 9:22. 2008..The goal of this study was to determine whether this residue is actually phosphorylated in yeast and if it is involved in the termination activity of the protein...
- Statistical analysis of readthrough levels for nonsense mutations in mammalian cells reveals a major determinant of response to gentamicinCélia Floquet
Universite Paris Sud, Institut de Genetique et Microbiologie, UMR8621, Orsay, France
PLoS Genet 8:e1002608. 2012..Finally, we point out that a uracil at this position associated with a cytosine at +4 results in an optimal gentamicin-induced readthrough, which is the therapeutically relevant variable...
- Towards a computational model for -1 eukaryotic frameshifting sitesMichael Bekaert
Génétique Moléculaire de la Traduction, UMR CNRS 8623, Universite Paris Sud, 91405 Orsay Cedex, France
Bioinformatics 19:327-35. 2003..Unconventional decoding events are now well acknowledged, but not yet well formalized. In this study, we present a bioinformatics analysis of eukaryotic -1 frameshifting, in order to model this event...
- The major 5' determinant in stop codon read-through involves two adjacent adeninesSanaa Tork
CNRS UMR 8621, , , 91405 Orsay Cedex, France

Institute of Biochemistry and Biophysics, Polish Academy of Sciences, , 02-106 Warsaw, Poland
Curr Genet 42:147-52. 2002..Summarizing, the elevated tRNA levels in maf1- Delta increase translational fidelity and, independently, affect growth under special conditions...
- Gene overexpression as a tool for identifying new trans-acting factors involved in translation termination in Saccharomyces cerevisiaeOlivier Namy
, , CNRS UMR8621, , 91405 Orsay Cedex, France
Genetics 161:585-94. 2002..Interestingly, among these candidates, we identified two genes, SSO1 and STU2, involved in protein transport and spindle pole body formation, respectively, suggesting puzzling connections with the translation termination process...
- Lack of pseudouridine 38/39 in the anticodon arm of yeast cytoplasmic tRNA decreases in vivo recoding efficiencyFrançois Lecointe
Laboratoire d Enzymologie et de Biochimie Structurales, CNRS, Avenue de la Terrasse, Bat 34, F 91198 Gif sur Yvette, France
J Biol Chem 277:30445-53. 2002..Therefore, the presence of pseudouridine 38 or 39 in the tRNA anticodon arm enhances misreading of certain codons by natural nonsense tRNAs as well as promotes frameshifting on slippery sequences in yeast...
