Outline of Final Research Achievements |
Our purpose is to develop proteins with properties different from widely used genome-editing proteins such as TALEN and CRISPR. In this study, we rationally designed novel proteins based on engrailed homeodomain and confirmed the binding specificity using bacterial one-hybrid assay. We successfully designed molecules with a strong affinity and high specificity for the target sequence which has two engrailed homeodomain binding sites. Also, we developed a method to evaluate molecular flexibility of DNA using electron density map of X-ray crystal structures.
