Genome-scale reconstruction of protein-protein interaction networks proves an efficient strategy for gathering functional information about proteins which cannot be characterized using homology-based methods alone. By examining linkages between characterized and unknown (or hypothetical) entities, individual proteins or logical protein groups can be assigned putative function based on the ‘guilt-by-association’ principle, within the context of the network. Such large-scale interactome models also provide information about local and global relationships between gene products, and can be used to elucidate novel pathways, study cellular behavior, or predict outcomes based on possible propagation routes of effects exerted by small molecules.
