10 Jun – Talk by Christoph Kreutz

Christoph Kreutz, Leopold Franzens Universität Innsbruck, gives a talk titled “Advanced stable isotope labeling methods for RNA NMR spectroscopy“.

Wednesday, 10/06/15 at 5 pm
Campus Riedberg, Biozentrum N100 /1.14

 

Our research is focused on the development of advanced stable isotope labelling protocols for nucleic acids. Using chemo-enzymatic transformations site-specifically 13C/15N/2H- modified building blocks are amenable that can be either used for the solid phase chemical synthesis of RNA (i.e. synthesis of phosphoramidite building blocks) or for the enzymatic production of RNA by in vitro transcription (i.e. synthesis of ribonucleotide triphosphate building blocks). The building blocks currently available in our laboratory will be presented along with selected applications including CPMG relaxation dispersion experiments, ZZ- exchange NMR and paramagnetic relaxation enhancements studies.

Abstract:

It is becoming increasingly clear that a RNA-binding proteins are key elements in regulating the cell’s transcriptome. Thus, unraveling the interaction network of the RNA-binding proteins by determining their binding sites is becoming an increasingly important topic. There are several high-throughput methods available to detect binding sites such as CLIP-seq. Since not all possible binding sites are covered due to differential expression in tissues and developmental states, the main problem is to come up with good motif descriptions to find missing binding sites and to evaluate the binding strength. Our new approach GraphProt uses an advanced machine learning approach based on our graph-kernel, and is able to use both structural profiles as well as detailed 2D-structures, and predicts missing binding sites with an high accuracy./blockquote>

Prof. Vikram Panse, ETH Zürich, gives a talk titled “Exploring the interface between ribosome assembly and nucleocytoplasmic transport“.

Wednesday, 04/02/15 at 5 pm

Campus Riedberg, Biozentrum N100/0.15

Abstract: Eukaryotic ribosome assembly is a spectacular example of a highly dynamic and regulated process that spans different cellular territories: the nucleus, nucleoplasm and the cytoplasm. This poorly understood process, which begins in the nucleolus, requires >350 conserved transiently associating assembly factors, whose site(s) of action and precise function(s) on pre-ribosomal particles are beginning to be elucidated.

Further, production of ribosomes relies on an active functional nucleocytoplasmic transport machinery: the nuclear import machinery ensures delivery of newly synthesized ribosomal proteins to assembling pre-ribosomal particles in the nucleolus, the site of biogenesis, and the nuclear export machinery catalyses the transport of correctly assembled pre-ribosomal particles through nuclear pore complexes into the cytoplasm, the site of function. I will elaborate on two recent works from my laboratory that are beginning to illuminate the unchartered interface between the nucleocytoplasmic transport machinery and the ribosome assembly pathway.
