Protein Function Prediction with Bioinformatics Approaches
The DNA sequence of the human genome is now known, yet we are only starting to understand the functional networks of the proteins encoded in it. The group is addressing this issue with a number of computational approaches, including hidden Markov models, Bayesian networks, clustering algorithms, evolutionary models, and discriminant statistical methods. The goal is to predict function both in terms of biochemical activity and role in a pathway. To predict pathway interactions we are developing integrative computational methods and databases with a focus on identifying new disease genes. The resulting networks are available at http://FunCoup.sbc.su.se/
