Outline of Final Research Achievements

Messenger RNA (mRNA) carrying “genetic information” has 3’ poly(A) tail whose length regulation plays central roles in the post-transcriptional control of gene expression. Thus far, we have elucidated the mechanism of mRNA deadenylation (the initiation of mRNA decay), as well as negative regulation of gene expression targeting the deadenylation step. In this study, we have demonstrated that the positive regulation of gene expression by the post-transcriptional polyadenylation widely exists in somatic cells, and succeeded in verifying its general mechanism.

Academic Significance and Societal Importance of the Research Achievements

生体内における遺伝子の発現調節は、翻訳の鋳型であるmRNAの量を調節することが重要であるが、その方法としてはmRNAの量を増やす転写の調節と、mRNA量を減らすmRNA分解の調節の2つの方法がある。これまで転写調節の研究が進展したが、本研究ではmRNA分解調節に焦点を置いて研究を行い、mRNAポリA鎖分解による負の調節機構に加えて、mRNAポリA鎖伸長による正の調節機構が存在することを新たに見出し、その普遍的分子機構を解明した点において学術的、社会的意義を有する。
