Mrd1p binds to pre-rRNA early during transcription independent of U3 snoRNA and is required for compaction of the pre-rRNA into small subunit processomes (2008)

Segerstolpe, Åsa, Lundkvist, Pär, Osheim, Yvonne N., Beyer, Ann L., Wieslander, Lars

In Saccharomyces cerevisiae, synthesis of the small ribosomal subunit requires assembly of the 35S pre-rRNA into a 90S preribosomal complex. SnoRNAs, including U3 snoRNA, and many trans-acting...

TOR regulates the subcellular distribution of DIM2, a KH domain protein required for cotranscriptional ribosome assembly and pre-40S ribosome export (2008)

Vanrobays, Emmanuel, Leplus, Alexis, Osheim, Yvonne N., Beyer, Ann L., Wacheul, Ludivine, Lafontaine, Denis L.J.

Eukaryotic ribosome synthesis is a highly dynamic process that involves the transient association of scores of trans-acting factors to nascent pre-ribosomes. Many ribosome synthesis factors are...

In Exponentially Growing Saccharomyces cerevisiae Cells, rRNA Synthesis Is Determined by the Summed RNA Polymerase I Loading Rate Rather than by the Number of Active Genes

French, Sarah L., Osheim, Yvonne N., Cioci, Francesco, Nomura, Masayasu, Beyer, Ann L.

Genes encoding rRNA are multicopy and thus could be regulated by changing the number of active genes or by changing the transcription rate per gene. We tested the hypothesis that the number of open...

Transcriptional termination by RNA polymerase I requires the small subunit Rpa12p

Prescott, Elizabeth M., Osheim, Yvonne N., Jones, Hannah S., Alen, Claudia M., Roan, Judith G., Reeder, Ronald H., ...

We identify Rpa12p of RNA polymerase I (Pol I) as a termination factor. Combined analyses using transcription run-on, electron microscopy-visualized chromatin spreading and RT-PCR have been applied...

Adenovirus Protein VII Condenses DNA, Represses Transcription, and Associates with Transcriptional Activator E1A

Johnson, Jeffrey S., Osheim, Yvonne N., Xue, Yuming, Emanuel, Margaux R., Lewis, Peter W., Bankovich, Alex, ...

Adenovirus protein VII is the major protein component of the viral nucleoprotein core. It is highly basic, and an estimated 1070 copies associate with each viral genome, forming a tightly condensed...

Esf2p, a U3-Associated Factor Required for Small-Subunit Processome Assembly and Compaction

Hoang, Tran, Peng, Wen-Tao, Vanrobays, Emmanuel, Krogan, Nevan, Hiley, Shawna, Beyer, Ann L., ...

Esf2p is the Saccharomyces cerevisiae homolog of mouse ABT1, a protein previously identified as a putative partner of the TATA-element binding protein. However, large-scale studies have indicated...

The PINc domain protein Utp24, a putative nuclease, is required for the early cleavage steps in 18S rRNA maturation

Bleichert, Franziska, Granneman, Sander, Osheim, Yvonne N., Beyer, Ann L., Baserga, Susan J.

Ribosome biogenesis is a complex process that requires >150 transacting factors, many of which form macromolecular assemblies as big and complex as the ribosome itself. One of those complexes, the...

Visual Analysis of the Yeast 5S rRNA Gene Transcriptome: Regulation and Role of La Protein▿ †

French, Sarah L., Osheim, Yvonne N., Schneider, David A., Sikes, Martha L., Fernandez, Cesar F., Copela, Laura A., ...

5S rRNA genes from Saccharomyces cerevisiae were examined by Miller chromatin spreading, representing the first quantitative analysis of RNA polymerase III genes in situ by electron microscopy. These...
