Our research:

RNA is at the center of all steps of gene expression. Cells can be defined by their transcriptomes, not by their genomes. We are interested in discovering many regulatory elements that are part of the RNA regulon and in identifying their interacting partners and their targets. To achieve this goal we adapted the classical SELEX procedure to be used in combination with genome sequences and deep sequencing. Genomic systematic evolution of ligands by exponential enrichment (SELEX) allows the isolation of protein binding RNAs independently of computational predictions and expression conditions. We used genomic SELEX with an E. coli library to isolate RNA aptamers against RNA polymerase and the regulator protein Hfq. We further selected RNA polymerase II binding aptamers from the yeast and human genomes. These experiments delivered thousands of genomic RNA aptamers that regulate gene expression. We are currently analyzing the mode of action of these aptamers.

Another focus in our laboratory deals with proteins that promote RNA folding: RNA chaperones. As model examples we are analyzing the mode of action of the E. coli protein StpA and the HIV-1 Tat peptide. While StpA promotes RNA annealing and strand exchange, HIV-1 Tat only promotes RNA annealing. Using biochemical and biophysical methods (NMR) we study the structural dynamics of both RNA and protein.
