Outline of Research at the Start

本領域研究では「生体適合反応化学を用いた糖鎖修飾(糖鎖ケミカルノックイン)による膜タンパク質動態の人為制御」を達成目標に据える。必要な技術開発を並行分担的に遂行すべく、下記3班で研究組織を構成し、各班員が横断的に関わることで融合研究を進めていく。総括班は計画班を広報・企画事務・共有設備提供などの観点から支援する。
A01:糖鎖修飾タンパク質を膜上で「つくる」
A02:化学プローブでタンパク質膜動態の糖鎖制御を「みる」
A03:糖鎖修飾と外部刺激でタンパク質膜動態を「あやつる」

Outline of Final Research Achievements

Cell-surface glycans are involved in membrane dynamics of biomolecules related to various functions of life, such as endocytosis, migration to rafts, and extracellular vesicle (EV) uptake. Glycans connected to membrane proteins play a central role in membrane dynamics. We hypothesized that the regulation of membrane protein dynamics by glycans may lead to new artificial methods for analysis and regulation of biological functions. We have developed technologies based on the integration of biocompatible chemistry and biological research, such as synthesis of homogeneous glycoproteins and developing a chemical labeling method to precisely track the dynamics and interactions of membrane glycoproteins. We have also persued "glycan chemical knock-in" as an innovative methodology to control the membrane dynamics of glycoproteins depending on the glycan structure, in which artificial glycans are modified on membrane proteins using biocompatible chemical reactions.

Academic Significance and Societal Importance of the Research Achievements

糖タンパク質膜動態の高精度な理解を進め、人為制御法へと導いていく。これにより新たな薬物送達系の創出や、生体適合化学反応(速度論的化学摂動)による新たな生命操作法の創出が期待できる。基礎科学的知見を基に、化学・生命科学の学術変革と新たな研究領域の創成に繋げ、新しい視点からの生物製剤DDSの創出や反応化学的摂動による新たな生命操作法の応用展開も期待される。
