Outline of Final Research Achievements

In this study, we have developed a new intracellular protein-protein interaction detection technology that detects cell proliferation associated with intracellular protein-protein interactions using a receptor or a signaling molecule downstream of receptors. In this method, the detection sensitivity of protein-protein interactions could be adjusted by adding a small molecule. Using this method, peptide-protein domain interactions could be detected generally, and high-affinity intracellular antibodies could be screened from a library.

Academic Significance and Societal Importance of the Research Achievements

ガンや感染症などの疾患は現代社会における脅威であるが、種々の疾患に対する効果的な治療薬は未だ確立されていないのが現状である。一方で、生体内のプロセスはほぼ全てがタンパク質間相互作用に支配されており、タンパク質間相互作用を標的とした創薬は無限の可能性がある。本研究では、種々の疾患の原因となるタンパク質間相互作用を標的として、生きた細胞内での治療薬のスクリーニング技術を開発したことから、学術的・社会的意義は高い。
