Research Abstract

平成16年度の本研究では、1種の海洋無脊椎動物サンプルから、3種の新規MMP2およびMT1-MMP阻害剤を得た(投稿準備中)。また、昨年度の研究で見出した新規MMP2阻害剤ageladine Aは、既存のMMP阻害剤とは全く異なる新しいタイプの阻害剤であることが期待されているため、X線結晶解析により阻害機構を明らかにするべく、結晶化に最適の組み換えタンパク質の作成を試みている。
また、Alphascreen(TM)を用いた、タンパク質-タンパク質相互作用阻害アッセイ法の構築を引き続き行い、組み換えCD44分子とMT1-MMP分子を用いて1pmol程度で相互作用を検出することに成功した。現在、MT1-MMPの相互作用部位であるPEXドメインのみを用いて、さらに高感度検出が可能なアッセイ系の立ち上げを行っている。
さらに、細胞表面に発現しているCD44およびMT1-MMPを標的にした抗体コートしたAlphaビーズを培養細胞に投与し準ところ、細胞の浸潤突起上に結合したビーズが認められたため、生細胞表面上で実際に形成されている複合体の形成および一分子観察を標的にしたアッセイ系の開発も試みている。
