(English Abstract)
Detecting protein complexes is essential work for understanding biological functions and processes. Most protein complexes detecting methods are based on clustering the protein interaction network. However, one of the difficulties in these methods originates from the fact that protein interactions suffer from high false positive rate. We propose a protein complex detecting algorithm which employs gene expression data, as well as protein interaction network. The proposed algorithm allows overlapping of the protein complexes based on the fact that some proteins can be involved in several complexes at the same time. As a result, we could confirm that our algorithm is more accurate than existing algorithms.
