The function and synthesis of ribosomesD L Lafontaine
FNRS, Universite Libre de Bruxelles, Departement de Biologie Moleculaire, IRMW Campus CERIA, Avenue Emile Gryson 1, B 1070 Brussels, Belgium
Nat Rev Mol Cell Biol 2:514-20. 2001..The mechanisms that underlie ribosomal synthesis, translocation and catalysis are now being unravelled, with practical implications for the design of antibiotics...
A 'garbage can' for ribosomes: how eukaryotes degrade their ribosomesDenis L J Lafontaine
Fonds de la Recherche Scientifique FRS F N R S, Institut de Biologie et de Médecine Moléculaire IBMM, Universite Libre de Bruxelles ULB, Charleroi Gosselies, Belgium
Trends Biochem Sci 35:267-77. 2010..This surveillance is active at every step of the ribosome synthesis pathway and on mature ribosomes, involves nearly entirely different mechanisms for the small and large subunits, and requires specialized subcellular organelles...
The evolutionarily conserved protein Las1 is required for pre-rRNA processing at both ends of ITS2Stéphanie Schillewaert
Fonds de la Recherche Scientifique, Universite Libre de Bruxelles, Charleroi Gosselies, Belgium
Mol Cell Biol 32:430-44. 2012..Consistently, we note the conspicuous presence of ~7- or 8-nucleotide extensions on both ends of 5.8S rRNA precursors and at the 5' end of pre-25S RNAs suggestive of a protected spacer fragment of similar length...
TOR regulates the subcellular distribution of DIM2, a KH domain protein required for cotranscriptional ribosome assembly and pre-40S ribosome exportEmmanuel Vanrobays
Fonds de la Recherche Scientifique FRS FNRS, Académie Wallonie Bruxelles, Institut de Biologie et de Médecine Moléculaires, Universite Libre de Bruxelles, Charleroi Gosselies, B 6041, Belgium
RNA 14:2061-73. 2008..Strikingly, DIM2 and RRP12 are both involved in the nucleocytoplasmic translocation of pre-ribosomes, suggesting that this step in the ribosome assembly pathway has been selected as a regulatory target for the TOR pathway...
Esf2p, a U3-associated factor required for small-subunit processome assembly and compactionTran Hoang
Fonds National de la Recherche Scientifique, Universite Libre de Bruxelles, Institut de Biologie et de Médecine Moléculaires, Charleroi Gosselies, Belgium
Mol Cell Biol 25:5523-34. 2005..The identification of ABT1 in a large-scale analysis of the human nucleolar proteome indicates that its role may also be conserved in mammals...
A functional interface at the rDNA connects rRNA synthesis, pre-rRNA processing and nucleolar surveillance in budding yeastNathalie Leporé
RNA Metabolism, Fonds de la Recherche Scientifique FRS FNRS, Universite Libre de Bruxelles, Charleroi Gosselies, Belgium
PLoS ONE 6:e24962. 2011..Altogether these results indicate that Nrd1-Nab3 contributes to recruiting the nucleolar surveillance to elongating polymerases to survey nascent rRNA transcripts...
The nuclear poly(A) polymerase and Exosome cofactor Trf5 is recruited cotranscriptionally to nucleolar surveillanceMaxime Wery
Fonds de la Recherche Scientifique FRS FNRS, AcadémieWallonie Bruxelles, Institut de Biologie et de Médecine Moléculaires, Universite Libre de Bruxelles, Charleroi Gosselies, B 6041 Belgium
RNA 15:406-19. 2009..Trf5 colocalized with nascent pre-rRNPs, indicating that this nucleolar surveillance initiates cotranscriptionally...
The small nucle(ol)ar RNA cap trimethyltransferase is required for ribosome synthesis and intact nucleolar morphologyGeoffroy Colau
Fonds National de la Recherche Scientifique, Universite Libre de Bruxelles, Institut de Biologie et de Médecine Moléculaires, Charleroi Gosselies, Belgium
Mol Cell Biol 24:7976-86. 2004..This conclusion is compatible with a model of self-organization for nucleolar assembly...
Dim2p, a KH-domain protein required for small ribosomal subunit synthesisEmmanuel Vanrobays
F N R S, Universite Libre de Bruxelles, Institut de Biologie et de Médecine Moléculaires, Charleroi Gosselies, Belgium LBME du CNRS, 31062 Toulouse Cedex 04, France
RNA 10:645-56. 2004....
