Protein fulfilling the their roles, one of important ways is through protein-protein interaction. In functional genomic era, identifying all of protein-protein interaction in proteome and mapping the protein interactions that have been attracting many scientists' attention , of which large-scale yeast two-hybrid system is one strategy of most widely used. In recent two years, ambitious projects have launched to examine all of the protein-protein interaction in Saccharomyces cer-evisiae using large-scale yeast two-hybrid system. Nevertheless, huge protein network is larger than that we predict and single yeast two-hybrid system cannot solve all the problems, which need be complemented by other wags.
