Bioinformatics Highlight: Protein structure prediction — state-of-the-art methods proven in contests

SeRC faculty Björn Wallner and Arne Elofsson are experts on protein structure predictions and have developed several tools for prediction and assessment of protein structure models. Their web service is a popular and important tool, and one of the first services using a truly distributed computational framework. It collects predictions from many different sites around the world and combines them with locally computed predictions. Furthermore, processing and analysis yields predictions superior to any of the incoming predictions. is consistently ranked among the best in the biennial community-wide Critical Assessment of Structure Prediction (CASP), the “Olympic games of protein structure prediction”. In the latest competition, tools developed by Wallner-Elofsson (Pcons, Pcomb, ProQ2) were part of the official “Top Performing Groups” for both easy and difficult modeling cases. Wallner and Elofsson recently obtained funding (from BILS) to develop for using a more modern framework.
