Box H/ACA small nucleolar ribonucleoprotein particles (H/ACA snoRNPs) play key roles in the synthesis of eukaryotic ribosomes. How box H/ACA snoRNPs are assembled remains unknown. Here we show that...
Snapshot of the Genome of the Pseudo-T-Even Bacteriophage RB49
Desplats, Carine, Dez, Christophe, Tétart, Françoise, Eleaume, Heïdy, Krisch, H. M.
RB49 is a virulent bacteriophage that infects Escherichia coli. Its virion morphology is indistinguishable from the well-known T-even phage T4, but DNA hybridization indicated that it was...

Box H/ACA small nucleolar ribonucleoprotein particles (H/ACA snoRNPs) play key roles in the synthesis of eukaryotic ribosomes. The ways in which these particles are assembled and correctly localized...

We have identified a novel essential nucleolar factor required for the synthesis of 5.8S and 25S rRNAs termed Npa1p. In the absence of Npa1p, the pre-rRNA processing pathway leading to 5.8S and 25S...
Functional link between ribosome formation and biogenesis of iron–sulfur proteins
Yarunin, Alexander, Panse, Vikram Govind, Petfalski, Elisabeth, Dez, Christophe, Tollervey, David, Hurt, Ed
In genetic screens for ribosomal export mutants, we identified CFD1, NBP35 and NAR1 as factors involved in ribosome biogenesis. Notably, these components were recently reported to function in...
Yeast Ntr1/Spp382 Mediates Prp43 Function in Postspliceosomes
Boon, Kum-Loong, Auchynnikava, Tatsiana, Edwalds-Gilbert, Gretchen, Barrass, J. David, Droop, Alastair P., Dez, Christophe, ...
The Ntr1 and Ntr2 proteins of Saccharomyces cerevisiae have been reported to interact with proteins involved in pre-mRNA splicing, but their roles in the splicing process are unknown. We show here...

We previously hypothesized that HEAT-repeat (Huntington, elongation A subunit, TOR) ribosome synthesis factors function in ribosome export. We report that the HEAT-repeat protein Sda1p is a component...

We report the characterization of the yeast Npa2p (Urb2p) protein, which is essential for 60S ribosomal subunit biogenesis. We identified this protein in a synthetic lethal screening with the rsa3...

Roles of the HEAT repeat proteins Utp10 and Utp20 in 40S ribosome maturation
Dez, Christophe, Dlakić, Mensur, Tollervey, David
A family of HEAT-repeat containing ribosome synthesis factors was previously identified in Saccharomyces cerevisiae. We report the detailed characterization of two of these factors, Utp10 and Utp20,...
