Cytoplasmic Recycling of 60S Preribosomal Factors Depends on the AAA Protein Drg1 (2007)

Pertschy, Brigitte, Saveanu, Cosmin, Zisser, Gertrude, Lebreton, Alice, Tengg, Martin, Jacquier, Alain, ...

Allelic forms of DRG1/AFG2 confer resistance to the drug diazaborine, an inhibitor of ribosome biogenesis in Saccharomyces cerevisiae. Our results show that the AAA-ATPase Drg1 is essential for 60S...

Genetic and Biochemical Characterization of Salmonella enterica Serovar Typhi Deoxyribokinase

Tourneux, Lise, Bucurenci, Nadia, Saveanu, Cosmin, Kaminski, Pierre Alexandre, Bouzon, Madeleine, Pistotnik, Elisabeth, ...

We identified in the genome of Salmonella enterica serovar Typhi the gene encoding deoxyribokinase, deoK. Two other genes, vicinal to deoK, were determined to encode the putative deoxyribose...

Nog2p, a putative GTPase associated with pre-60S subunits and required for late 60S maturation steps

Saveanu, Cosmin, Bienvenu, David, Namane, Abdelkader, Gleizes, Pierre-Emmanuel, Gas, Nicole, Jacquier, Alain, ...

Eukaryotic ribosome maturation depends on a set of well ordered processing steps. Here we describe the functional characterization of yeast Nog2p (Ynr053cp), a highly conserved nuclear protein. Nog2p...

Sequential Protein Association with Nascent 60S Ribosomal Particles

Saveanu, Cosmin, Namane, Abdelkader, Gleizes, Pierre-Emmanuel, Lebreton, Alice, Rousselle, Jean-Claude, Noaillac-Depeyre, Jacqueline, ...

Ribosome biogenesis in eukaryotes depends on the coordinated action of ribosomal and nonribosomal proteins that guide the assembly of preribosomal particles. These intermediate particles follow a...

The ribosomal protein Rps15p is required for nuclear exit of the 40S subunit precursors in yeast

Léger-Silvestre, Isabelle, Milkereit, Philipp, Ferreira-Cerca, Sébastien, Saveanu, Cosmin, Rousselle, Jean-Claude, Choesmel, Valérie, ...

We have conducted a genetic screen in order to identify ribosomal proteins of Saccharomyces cerevisiae involved in nuclear export of the small subunit precursors. This has led us to distinguish...

Staphylococcus aureus RNAIII and the endoribonuclease III coordinately regulate spa gene expression

Huntzinger, Eric, Boisset, Sandrine, Saveanu, Cosmin, Benito, Yvonne, Geissmann, Thomas, Namane, Abdelkader, ...

Staphylococcus aureus RNAIII is one of the largest regulatory RNAs, which controls several virulence genes encoding exoproteins and cell-wall-associated proteins. One of the RNAIII effects is the...

The p21-Activated Protein Kinase Inhibitor Skb15 and Its Budding Yeast Homologue Are 60S Ribosome Assembly Factors▿

Saveanu, Cosmin, Rousselle, Jean-Claude, Lenormand, Pascal, Namane, Abdelkader, Jacquier, Alain, Fromont-Racine, Micheline

Ribosome biogenesis is driven by a large number of preribosomal factors that associate with and dissociate from the preribosomal particles along the maturation pathway. We have previously shown that...

A functional network involved in the recycling of nucleocytoplasmic pre-60S factors

Lebreton, Alice, Saveanu, Cosmin, Decourty, Laurence, Rain, Jean-Christophe, Jacquier, Alain, Fromont-Racine, Micheline

Eukaryotic pre-ribosomes go through cytoplasmic maturation steps before entering translation. The nucleocytoplasmic proteins participating in these late stages of maturation are reimported to the...

Structural and nucleotide-binding properties of YajQ and YnaF, two Escherichia coli proteins of unknown function

Saveanu, Cosmin, Miron, Simona, Borza, Tudor, Craescu, Constantin T., Labesse, Gilles, Gagyi, Cristina, ...

Structural genomics is a new approach in functional assignment of proteins identified via whole-genome sequencing programs. Its rationale is that nonhomologous proteins performing similar or related...
