Outline of Final Research Achievements |
A yeast and phage, carrying coiled-coil forming peptide were successfully fabricated, indicated that they enable to interact with each other and target population was enriched by using FACS. Some mutated peptide pairs suppressed the anti-parallel binding were designed, demonstrated that this mutant improves the performance of a probe.

Academic Significance and Societal Importance of the Research Achievements |
本研究で検討した酵母とファージを利用したペプチドのスクリーニング法は、より高効率に目的集団を濃縮できる条件について検討を重ねることで、新しい機能性ペプチドを獲得する手段として利用が期待される。また、今回新たに設計・合成した逆平行結合抑制ペプチドペアは、今後の高性能なQ-bodyの作製に資すると考えられる。
