本計画研究の概要
私たちは、SNIPER(Specific and Nongenetic IAP-dependent Protein Eraser)やセレブロン(CRBN)モジュレーター（別名：IMiDs免疫調節剤）等の化合物を利用して細胞内の標的タンパク質をユビキチン化し、プロテアソームで分解するケミカルプロテインノックダウン技術を確立してきました。SNIPERはIAPに結合するリガンド(IAPアンタゴニスト)と標的タンパク質に結合するリガンド(分子弾頭)を繋いだキメラ化合物であり、ユビキチンリガーゼ(E3)活性を持つIAPを標的タンパク質にリクルートする事によりユビキチン化を引き起こします。分子弾頭を置換することによって様々な標的タンパク質を狙って分解する事ができる汎用性の高い技術です。一方CRBNモジュレーターは複合体型E3の基質認識分子であるCRBNに結合して基質特異性を変化させる化合物です。これらの化合物は、分解だけでなく細胞膜受容体の内在化などユビキチンが関与するさまざまな細胞応答を誘導できることが最近わかってきました。
本研究では、これらのケミカルプロテインノックダウン技術を利用して様々な標的タンパク質をユビキチン化し、領域内の研究班と協力して細胞応答等を解析する事により、ユビキチンコードの作動機構の解明に挑戦します。
1. SNIPERテクノロジーの開発と拡充
様々な標的タンパク質をIAPでユビキチン化するSNIPER化合物を各種合成します。また様々なE3リガーゼで標的タンパク質をユビキチン化する各種の化合物と実験系を開発します。これらの化合物で引き起こされる細胞応答とそのメカニズムを解明します。
2. SNIPER等の化合物を利用したユビキチンコード作動機構の解析
上記で開発したSNIPER等を利用して、形成されるユビキチン鎖、デコーダー分子、細胞応答等を解析し、ユビキチンコード作動機構の一端を解明します。
3. CRBNモジュレーターの開発と催奇形性・治療効果のメカニズム
サリドマイド等の存在下におけるCRBN結合因子の網羅的探索を質量分析計で行い、催奇形性や治療効果に関与する基質とメカニズムを解明します。
4. SNIPER等によって形成されるE3リガーゼとネオ基質複合体の構造解析
SNIPERやCRBNモジュレーターによって形成されるE3リガーゼとネオ基質複合体の結晶構造を解析し、ネオ基質がE3リガーゼに認識される機構を分子レベルで解明します。
5. マイトファジー誘導技術の開発
マイトファジー誘導に必要なユビキチンコードを明らかにし、マイトファジーを誘導する技術及び化合物の開発を進めます。
