Outline of Final Research Achievements |
Biopharmaceuticals are quite expensive which is a social problem. We set sail for developing a safe and cheap production system for biopharmaceuticals using wood rot fungi and in vitro transglycosylation reaction. We successfully produced human proteins fused with homologous secretion signal in the culture filtrate of recombinant P. ostreatus. And purified versatile peroxidase was treated with variant of Endo-M, resulting in product with altered glycosylation profile. Furthermore, we have successfully developed a genome-editing system in this fungus for the first time.

Academic Significance and Societal Importance of the Research Achievements |
我々がこれまでの研究で開発してきた木材腐朽菌(担子菌)における異種タンパク質発現のためのプラットフォームをより効率化し、ヒト由来のタンパク質の分泌発現を実現した。さらに、モデルタンパク質を用いたin vitroでの糖鎖転移反応が実際に起きることを示すことにより、さらに研究を続けることでヒラタケを用いたバイオ医薬品の生産が可能である事が示された。また、ゲノム編集系の確立は、本課題の継続的発展に留まらず木材腐朽菌、食用担子菌類における分子遺伝学の発展に大きく貢献することが期待される。
