Outline of Research at the Start

本研究では、クロマチン構成因子DEKによるクロマチン構造制御機構の解析を行う。DEKは、癌化やリウマチ関節炎に関与することが知られており、細胞核内に大量かつユビキタスに存在する因子であるにもかかわらず、クロマチンに及ぼす影響についてはほとんど不明である。本研究では、構造生物学的、生化学的手法を中心に、DEKとクロマチンの相互作用解析を行うことで、DEKによるクロマチン構造制御機構を解明する。さらに、DEKと他のクロマチン構造形成因子との比較を行うことで、真核生物におけるクロマチン構造形成の多様性の解明を試みる。

Outline of Final Research Achievements

In eukaryotic cells, the genomic DNA forms chromatin structure. A chromatin associated oncogene, DEK, reportedly changes chromatin structure and affects various nuclear processes, such as transcription, splicing, and DNA repair, maintaining chromatin integrity. In this study, structural and biochemical analyses of DEK-chromatin complex were performed. These results demonstrated the unique regulation of chromatin by DEK.

Academic Significance and Societal Importance of the Research Achievements

クロマチンは、多様な構造変化を介して転写や、複製、DNA修復などの広範な核内プロセスを制御することで、発生、老化、癌化などの複雑な生命現象を実現する。しかしながら、クロマチンがどのように構造変換されるのかについては未だ不明な点が多い。本研究では、クロマチンに結合するがん遺伝子DEKによるクロマチン制御機構の一端を解明した。本知見は、核内におけるクロマチン制御機構の知識を深化するものであり、多様な核内プロセスが調節されるメカニズムを考える一助となる。また、癌におけるDEKの作用機序と、癌に対する創薬への知見を提供する。
