چکیده انگلیسی
Compounds that selectively interfere with protein-protein interactions are not only invaluable as biological reagents, but may ultimately serve as therapeutically useful drugs for the treatment of a wide variety of disease states. However, unlike active site directed inhibitors that bind to a relatively small, well-defined, hydrophobic pocket, reagents that disrupt protein-protein interactions must contend with a protein surface that is comparatively large, ill defined, and solvent exposed. We have developed a straightforward method for the acquisition of protein-protein interaction inhibitors. The library-based strategy starts with low affinity consensus sequence peptides, which are then transformed in a stepwise fashion into high affinity inhibitors. The approach has been used to create potent ligands for SH2 and SH3 domains, as well as powerful and highly selective inhibitors for protein kinases and phosphatases. The protocol is easily automated and therefore has the potential to be routinely applied, in a high throughput fashion.
