Major Research Interests

The majority of genes in higher eukaryotes contain protein-coding exons that can be joined in a combinatorial fashion. The process, termed pre-mRNA splicing, is an essential step in gene expression, and it expands tremendously the proteome and the complexity of an organism. Our goal is to understand the structural basis of pre-mRNA splicing. Here we place particular emphasis on the spliceosome's regulation, as well as on the misregulation that causes various diseases.

DNA catalysts are an increasingly important topic in the work pursued in our laboratory. The surprisingly complex fold that these molecules adopt raises questions about the structural importance of DNA in the cell, and it enables us to manipulate the molecules' properties for technological applications.

For our investigations we make use of biochemistry, X-ray crystallography and - increasingly - electron microscopy.
