Outline of Research at the Start

特定の波長の光照射によって二重鎖形成と解離を自在に制御できる人工核酸SNAを設計し、鋳型となる核酸上でSNA断片を連結する「SNA光ライゲーション法」を開発する。
この系を利用することで、シグナル増幅によるRNA高感度検出システムを構築し、微量RNAを配列特異的に検出することを目指す。更に、全く新しいナノ構造体として核酸ポリカテナン作成を試みる。

Outline of Final Research Achievements

Ligation of nucleic acids generates complementary strand for template from fragment strands via formation of phosphodiester bond, which is significantly important for various biological technology including genetic recombination, nucleic acid architecture, and nucleic acid detection. In this project, we have newly developed photo-ligation of SNA, artificial nucleic acid, on a template RNA strand. SNA fragments carrying photo-responsive nucleobase can be effectively ligated on RNA template by the irradiation of 365 nm light.

Academic Significance and Societal Importance of the Research Achievements

今回開発した光ライゲーション反応は特定のRNA配列存在下でのみSNA鎖を連結する反応であるため、RNAを標的とする新たなRNA検出システムや核酸医薬としての応用が期待できる。また、本研究の過程で新たに開発した光応答性核酸塩基NVAは、過去に報告しているPVAと同様の二重鎖光制御を、より短波長の光照射で行うことができるため、PVAとNVAを併用することで複雑な核酸分子マシンを構築することが可能となった。
