Aktuel forskning

Our research activity is primarily centred on intracellular protein degradation via the ubiquitin-proteasome pathway. The ubiquitin-proteasome system (link to Bookshelf) is highly conserved and is the major pathway for intracellular proteolysis in all eukaryotic cells. Accordingly, ubiquitin-dependent protein degradation plays a pivotal role in the turnover of key regulatory proteins involved in a series of cellular processes, including cell cycle control, signal transduction, DNA repair, vesicle transport and protein folding. Expectedly, malfunctions in this cellular system are connected with a variety of diseases such as cancer and viral infections as well as neurodegenerative diseases like Parkinson's disease and Alzheimer's syndrome.

In our studies we utilise human tissue culture cells and the fission yeast Schizosaccharomyces pombe as model organisms. As the ubiquitin-proteasome system is remarkably well conserved we tend to use yeast for answering basic cell biological questions as this allows for swifter molecular biological manipulations without limiting the overall scope of the projects. However, when yeast cannot be utilised we use human cells in tissue culture.
Primarily our approach to gaining insight into the molecular mechanisms of intracellular protein degradation is focused on determining novel protein-protein interactions between components of the system. To this end we utilise a variety of genetic, biochemical and molecular biological techniques including, chemical cross-linking, surface plasmon resonance, co-precipitation of fusion proteins, yeast two-hybrid analyses and cDNA suppressor screens. For reviews which are focused on our research interests please see Madsen et al., 2009 (link to PubMed) and Hartmann-Petersen & Gordon, 2004 (link to PubMed).
