Outline of Annual Research Achievements

これまでに新規ガス応答性ヘムタンパク質PGRMC1の結晶構造解析に成功し、これがヘムを介した新規の2量体構造を示す事を明らかとし、ヘムによる2量体形成によってPGRMC1はEGFRやシトクロムP450と会合して、がん増殖の進展に関わる事を見出した(Nature Commun 2017)。さらに、イタリアBari大学との共同研究により、抗癌活性を有するsigma 2 ligandと呼ばれる化合物群がPGRMC1と結合することを明らかとした(Pharmacol Res. 2017)。また、PGRMC1に選択的に結合して機能を制御する低分子化合物のスクリーニングを実施し、いくつかのシーズ候補化合物を得ている。さらに、遺伝子組み換えマウスを用いたPGMRC1の未知の生理機能について解析を進めており、肝機能や脂質代謝に関わる知見を得ている。今後は、これらの知見を基にPGRMC1の機能的な解明行い、PGRMC1を標的としたシーズ化合物を用いた制御による創薬展開を目指す予定である。
