Outline of Research at the Start

ダイナミンはアクチン、微小管、生体膜を制御する。ダイナミンとそのターゲットは、重合脱重合、変形などダイナミック変化するため分子の作動実態は未解明である。我々は最近、ダイナミンの膜切断過程をin vitroで再現し、その働きを直接観察した(Takeda et al. eLife 2018)。in vitro再構成系と細胞レベルの解析により、アクチン、微小管、生体膜に対するダイナミンの作動実態と、ダイナミンのマルチ機能が細胞内で連携統合する仕組みを解析する。ダイナミンファミリー分子に共通する本質的分子マシナリーの解明、マルチ機能の統合の仕組みの解明、ダイナミン変異疾患の病態解明を目指す。

Outline of Final Research Achievements

We found that Charcot-Marie-Tooth disease-associated mutations of dynamin 2 cause aberrant stress fibers, showing that dynamin is required for the formation and stabilization of stress fibers. And we reconstituted in vitro the actin bundle formation by dynamin. We also found that dynamin 1 bundles microtubules, and showed that this bundling is necessary for the primary processes formation and stabilization of cell morphology of renal glomerular podocytes. The microtubule-binding site of dynamin 1 was identified. Furthermore, regarding the regulation of membrane dynamics, we demonstrated that dynamin 2 and BIN1, a BAR protein, cooperatively function in T-tubule formation and stabilization of skeletal muscle cells.

Academic Significance and Societal Importance of the Research Achievements

ダイナミンの変異が、てんかん性脳症や末梢神経変性疾患Charcot-Marie-Tooth病、先天性筋疾患の一つである中心核ミオパチーの原因となることがわかり、それらの疾患に関連するダイナミン変異も多数報告されている。ダイナミン分子の生理的機能、作動機構を解明するとともに、変異に伴う機能破綻のメカニズムを明らかにすることは、これらの難治性疾患の分子病態の解明や新規の診断、治療の開発に不可欠である。
