Outline of Final Research Achievements |
The aim of this research is the development of novel nonstandard peptide drugs that regulate protein-protein interaction. Unfortunately, no effective methodologies for screening such molecules have been established to date. Here, we first developed two macrocyclic peptides that independently bind to IL28RA and IL10R2 by means of the RaPID display. Both of the peptides showed strong binding affinities against the target molecules with low-nM KD values. Then, we introduced the two peptide sequences into an Fc region of antibody so that both of IL28RA and IL10R2 can be targeted by this molecule at the same time. Currently, evaluation of binding affinity and bioactivity of this molecule is underway.
