Functional analysis of saccharomyces cerevisiae ribosomal protein Rpl3p in ribosome synthesis
(Oxford University Press, 2007)
Ribosome synthesis in eukaryotes requires a multitude oftrans-acting factors. These factors act at many steps as the pre-ribosomal particles travel from the nucleolus to the cytoplasm. In contrast to the well-studied ...

Increased sensitivity to protein synthesis inhibitors in cells lacking tmRNA
(Cold Spring Harbor Laboratory Press, 2001)
tmRNA (also known as SsrA or 10Sa RNA) is involved in a trans-translation reaction that contributes to the recycling of stalled ribosomes at the 3′ end of an mRNA lacking a stop codon or at an internal mRNA cluster of rare ...

Characterization of saccharomyces cerevisiae Npa2p (Urb2p) reveals a low-molecular-mass complex containing Dbp6p, Npa1p (Urb1p), Nop8p, and Rsa3p involved in early steps of 60S ribosomal subunit biogenesis
(American Society for Microbiology, 2007)
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 thersa3null allele. Rsa3p is a ...

The essential WD-repeat protein Rsa4p is required for rRNA processing and intra-nuclear transport of 60S ribosomal subunits
(Oxford University Press, 2005)
We report the characterization of a novel factor, Rsa4p (Ycr072cp), which is essential for the synthesis of 60S ribosomal subunits. Rsa4p is a conserved WD-repeat protein that seems to localize in the nucleolus.In ...

Npa1p is an essential trans-acting factor required for an early step in the assembly of 60S ribosomal subunits in Saccharomyces cerevisiae
(Cold Spring Harbor Laboratory Press, 2004)
Ribosome biogenesis requires > 100 nonribosomal proteins, which are associated with different preribosomal particles. The substrates, the interacting partners, and the timing of action of most of these proteins are largely ...

An Antifungal Exo-alpha 1,3-Glucanase (AGN13.1) from the Biocontrol Fungus Trichoderma harzianum
(American Society for Microbiology, 2001)
Trichoderma harzianum secretes α-1,3-glucanases when it is grown on polysaccharides, fungal cell walls, or autoclaved mycelium as a carbon source (simulated antagonistic conditions). We have purified and characterized one ...
