gar2 is a nucleolar protein from Schizosaccharomyces pombe required for 18S rRNA and 40S ribosomal subunit accumulation (1995)

Gulli, Marie-Pierre, Girard, Jean-Philippe, Zabetakis, Dan, Lapeyre, Bruno, Melese, Teri, Caizergues-Ferrer, Michele

Several nucleolar proteins, such as nucleolin, NOP1/flbrillarln, SSB1, NSR1 and GAR1 share a common glycine and arglnlne rich structural motif called the GAR domain. To identify novel nucleolar...

Study of multiple fibrillarin mRNAs reveals that 3' end formation in Schizosaccharomyces pombe is sensitive to cold shock (1993)

Girard, Jean-Philippe, Feliu, Jacgues, Caizergues-Ferrer, MichÈle, Lapeyre, Bruno

Flbrillarin is a nucleolar protein which is associated with small nucleolar RNAs, and is required for pre-rRNA processing. We have cloned and characterized the gene encoding flbrillarin in the...

Cloning of cDNA encoding a 100 kDa nudeolar protein (nucleoline) of Chinese hamster ovary cells (1985)

Lapeyre, Bruno, Caizergues-Ferrer, Michèle, Bouche, Gérard, Amalric, François

Nucleoline (100 kDa) is the major nucleolar protein in exponentially growing cells that behaves like a nucleolar organizer protein and plays a key role in rDNA transcription and prerRNA processing....

Spb1p Is a Yeast Nucleolar Protein Associated with Nop1p and Nop58p That Is Able To Bind S-Adenosyl-l-Methionine In Vitro

Pintard, Lionel, Kressler, Dieter, Lapeyre, Bruno

We present here the characterization of SPB1, an essential yeast gene that is required for ribosome synthesis. A cold-sensitive allele for that gene (referred to here as spb1-1) had been previously...

The Two Proteins Pat1p (Mrt1p) and Spb8p Interact In Vivo, Are Required for mRNA Decay, and Are Functionally Linked to Pab1p

Bonnerot, Claire, Boeck, Ronald, Lapeyre, Bruno

We report here the characterization of a bypass suppressor of pab1Δ which leads to a fourfold stabilization of the unstable MFA2 mRNA. Cloning of the wild-type gene for that suppressor reveals that...

Capped mRNA Degradation Intermediates Accumulate in the Yeast spb8-2 Mutant

Boeck, Ronald, Lapeyre, Bruno, Brown, Christine E., Sachs, Alan B.

mRNA in the yeast Saccharomyces cerevisiae is primarily degraded through a pathway that is stimulated by removal of the mRNA cap structure. Here we report that a mutation in the SPB8 (YJL124c) gene,...

Trm7p catalyses the formation of two 2′-O-methylriboses in yeast tRNA anticodon loop

Pintard, Lionel, Lecointe, François, Bujnicki, Janusz M., Bonnerot, Claire, Grosjean, Henri, Lapeyre, Bruno

The genome of Saccharomyces cerevisiae encodes three close homologues of the Escherichia coli 2′-O-rRNA methyltransferase FtsJ/RrmJ, designated Trm7p, Spb1p and Mrm2p. We present evidence that...

MRM2 encodes a novel yeast mitochondrial 21S rRNA methyltransferase

Pintard, Lionel, Bujnicki, Janusz M., Lapeyre, Bruno, Bonnerot, Claire

Mitochondria of the yeast Saccharomyces cerevisiae assemble their ribosomes from ribosomal proteins, encoded by the nuclear genome (with one exception), and rRNAs of 15S and 21S, encoded by the...

Trm11p and Trm112p Are both Required for the Formation of 2-Methylguanosine at Position 10 in Yeast tRNA†

Purushothaman, Suresh K., Bujnicki, Janusz M., Grosjean, Henri, Lapeyre, Bruno

N2-Monomethylguanosine-10 (m2G10) and N2,N2-dimethylguanosine-26 (m22G26) are the only two guanosine modifications that have been detected in tRNA from nearly all archaea and eukaryotes but not in...
