Outline of Final Research Achievements

Actin plays an important role in various cell functions by converting between monomeric and filamentous states. In this study, in order to understand how actin functions, we defined the conformational space for available structure of actin and showed existing of four clusters within the space (G-form, F-form, C-form and O-form). In addition, we revealed transitions between four cluster structures. We also studied the structure of fragmin, which regulates actin function.

Academic Significance and Societal Importance of the Research Achievements

蛋白質は構造を変化させながら機能している。そのため、蛋白質の機能プロセスを理解するためには構造転移を解明する必要がある。この考えをアクチンに適用してアクチンの構造空間を定義した。この空間は研究者がアクチンの構造転移を議論する際の共通基盤となる。また、本研究で得られたゲルゾリン・ファミリーに属するフラグミン対する知見は、ゲルゾリンの基礎研究やその医療応用に貢献することが期待される。ゲルゾリンは医学の見た場合非常に重要な蛋白質で、例えばその欠乏が敗血症を引き起こす。
