Vanrobays, Emmanuel, Gleizes, Pierre-Emmanuel, Bousquet-Antonelli, Cécile, Noaillac-Depeyre, Jacqueline, Caizergues-Ferrer, Michèle, Gélugne, Jean-Paul
Numerous non-ribosomal trans-acting factors involved in pre-ribosomal RNA processing have been characterized, but none of them is specifically required for the last cytoplasmic steps of 18S rRNA...
The box H+ACA snoRNAs carry Cbf5p, the putative rRNA pseudouridine synthase
Lafontaine, Denis L.J., Bousquet-Antonelli, Cécile, Henry, Yves, Caizergues-Ferrer, Michèle, Tollervey, David
Many or all of the sites of pseudouridine (Ψ) formation in eukaryotic rRNA are selected by site-specific base-pairing with members of the box H + ACA class of small nucleolar RNAs (snoRNAs)....
Synthesis and processing of tRNA-related SINE transcripts in Arabidopsis thaliana
Pélissier, Thierry, Bousquet-Antonelli, Cécile, Lavie, Laurence, Deragon, Jean-Marc
Despite the ubiquitous distribution of tRNA-related short interspersed elements (SINEs) in eukaryotic species, very little is known about the synthesis and processing of their RNAs. In this work, we...

A bona fide La protein is required for embryogenesis in Arabidopsis thaliana
Fleurdépine, Sophie, Deragon, Jean-Marc, Devic, Martine, Guilleminot, Jocelyne, Bousquet-Antonelli, Cécile
Searches in the Arabidopsis thaliana genome using the La motif as query revealed the presence of eight La or La-like proteins. Using structural and phylogenetic criteria, we identified two putative...
