Topic

Ribosomes catalyze the translation of mRNA into proteins. Thereby, they have a key role in gene expression, cell growth and cell cycle progression. Ribosomes are large ribonucleo-protein complexes (RNP’s) consisting  of  ribosomal RNA (rRNA) and a large number (>50) of ribosomal proteins (r-proteins). Recent years brought detailed insights into the 3D-organisation of rRNA and r-proteins in mature ribosomes. In addition, it became evident that a significant proportion of the genome of an unicellular eukaryote (bakers yeast S. cerevisiae) codes for factors which are required for making ribosomes. Taking yeast as model system, we use a variety of in vivo and in vitro approaches to study the interrelationship between important  processes  in eukaryotic ribosome biogenesis, namely RNA synthesis, RNA processing, RNA folding, RNP assembly, and intracellular transport of  RNP precursors.
