W. G. Pritchard Lab Seminar: 4:00-5:00 PM, 101 Osmond Laboratory **Tuesday October 28, 2003** An integrated approach for protein function prediction Fengzhu Sun Molecular and Computational Biology Program Department of Biological Sciences University of Southern California Abstract: Assigning functions to novel proteins is one of the most important problems in the post-genomic era. Many different sources of genomic data, such as protein-protein physical interactions, genetic interactions, gene expressions, and domain structure contain information about protein function. We developed a novel approach that employs the theory of Markov random fields to infer a protein's functions using an integrated approach combining various sources of biological data. The model is flexible in that other protein pairwise relationship information and features of individual proteins can be easily incorporated. We apply our integrated approach to predict functions of yeast proteins.
