Outline of Final Research Achievements

In many eukaryotic cells, two distinct condensin complexes (condensins I and II) cooperate to support mitotic chromosome assembly. To understand the molecular mechanisms of action of the two complexes, we performed a comprehensive set of functional analyses of recombinant complexes (wild type and various mutants) using frog egg extracts. As a result, we were able to identify functional similarities and differences between condensins I and II. We also found that an intrinsically disordered region unique to each complex is involved in phosphorylation-mediated cell cycle regulation. Mathematical modeling and simulations revealed the possibility that the superhelical tension introduced by condensins contributes to mitotic chromosome assembly.

Academic Significance and Societal Importance of the Research Achievements

本研究の成果は、分裂期染色体構築に中心的な役割を果たす2つのコンデンシン複合体の機能とその制御の理解に対して、実験と理論の両面から大きな貢献をするものである。本研究で得られた成果は、いずれも世界をリードするものであり、分裂期染色体構築を超えて周辺分野(例えばコヒーシンによる間期染色体構築)に対して大きなインパクトを与えるものである。その意味において学術的意義はきわめて大きい。
