| Research Abstract |
An efficient methodology that facilitates selecting a polypeptide fragment that specifically inhibits the targeted protein-protein interaction has been established in this research. I have demonstrated an interaction domain, or a polypeptide responsible for the binding surface-formation, from either of the targeted proteins can be a competitive inhibitor against the interaction between the native proteins in vivo. A novel screening system with a quantitative reporter gene(an engineered fungal cDNA for secretory beta-galactosidase, LacA3) was also developed to facilitate a directed evolution of the inhibitor fragment.
