Outline of Final Research Achievements

The technology to directly manipulate arbitrary intracellular DNA molecules has made great progress with the advent of genome editing technologies such as CRISPR and TALEN. On the other hand, there are no technology that manipulate or modify cellular RNA molecules except the antisense technology.
PPR (pentatricopeptide repeat) is a RNA binding protein that can be designed for the sequence specificity. In this study, I developed a technology that can control the expression level of endogenous protein specifically and precisely by fusing translation related domain to designed PPR protein.

Academic Significance and Societal Importance of the Research Achievements

ヒトには約40兆個の細胞がそれぞれ役割を持ち集合することで生命が支えられている。それら細胞の振る舞いを決定付けるようなプログラムは、ゲノム上に書かれているが、個々の役割を決定づける情報としてゲノムからRNA、タンパク質が合成される。本研究は、設計図であるゲノムを変えることなく、RNAを変えることで細胞を自由に操作する方法である。この実現により、新しい創薬としての医療応用、新しい品種改良方法といった農業利用の可能性がある。
