Outline of Research at the Start

細胞表面の糖鎖は、クラスタを形成して個々の糖鎖分子では成し得ない高度な細胞認識を実現している。ウィルス表面糖鎖を認識するワクチンの開発も進められているが、糖鎖構造は複雑かつ柔軟性が高いため、糖鎖クラスタの立体構造情報はほとんど得られていない。本研究では、拡張アンサンブル法を用いた糖鎖計算技術に基づいた糖鎖クラスタの立体構造計算法を開発し、それを用いてウイルス表面糖鎖のクラスタ構造を解明し糖鎖クラスタの認識モデルを創出する。

Outline of Final Research Achievements

The protein glycosylation affects a protein-antibody interaction, but a little is known about the effect because of the diverse structures and interactions of glycans. Here, we built an atomistic model of a fully glycosylated envelope protein complex of the Lassa virus. Using molecular dynamics simulations, we show that the glycans form distinct clusters to non-uniformly shield the protein surface. We integrated the simulation results with existing sequence- and structure-based epitope prediction methods and successfully recovered known protein epitopes and even predicted new ones. This work provides a molecular basis for integrating otherwise elusive structural properties of glycans into vaccine and neutralizing antibody developments.

Academic Significance and Societal Importance of the Research Achievements

細胞表面を覆う糖鎖はがんや感染症など多くの病気と関係する。しかし、複雑で柔らかい糖鎖構造を実験で見るのは未だ難しい。特に複数の糖鎖が集まった時にどの様な構造をとるかはほとんど知られていなかった。本研究成果は糖鎖集合のクラスタ形成を原子解像度で示すもので、従来仕組みのわからなかった高度な糖鎖機能を説明する新たな視点を与える。さらに、糖鎖を標的とするワクチン開発にも役立つと期待され、学術的にも社会的にも意義は大きい。
