Outline of Research at the Start

セントロメアは、正確な染色体分配に必須なゲノム領域であるが、興味深いことに、多くの生物のセントロメアは、塩基配列による“ゲノム情報”では規定されずに、エピジェネティックな“非ゲノム情報”によって規定される。CENP-Aと呼ばれるセントロメアに特異的なヒストンがエピジェネティックな目印として働いていると考えられてはいるが、セントロメアを規定するための“非ゲノム情報”の実体については不明な点が多い。本研究では、代表者の独自の実験系を活用して、セントロメアが形成される際に必要な“非ゲノム情報”の実体の解明を目指す。

Outline of Annual Research Achievements

セントロメアは、染色体分配に必須なゲノム領域である。興味深いことに、多くの生物のセントロメアは、塩基配列による“ゲノム情報”では規定されずに、エピジェネティックな“非ゲノム情報”によって規定される。CENP-Aと呼ばれるセントロメアに特異的なヒストンがエピジェネティックな目印として働いていると考えられてはいるが、セントロメアを規定するための“非ゲノム情報”の実体については不明な点が多い。本研究では、セントロメアが形成される際に必要な“非ゲノム情報”の実体の解明を目指した。具体的には、I) 配列に依存しないでセントロメアと相互作用するゲノム領域の特徴解明、II) ゲノム複製の前後で変化するセントロメアに特異的なクロマチン構造の実体解明を目指す研究を行った。配列に依存しないでセントロメアと相互作用するゲノム領域の特徴解明を目指して、ネオセントロメア実験系を活用して新規にCENP-Aが導入されるために必要なクロマチンを調べた。従来知られていたMis18複合体でライセンスされるクロマチンに加えて、CENP-Iでライセンスされるクロマチンの存在を示した。また、セントロメアが他のクロマチン領域よりコンパクトな構造をとることを、3C,4C,Hi-C解析から明らかにできた。今後は、このコンパクトさをうむ分子機構や、なぜ、CENP-IでライセンスされたクロマチンへCENP-Aが取り込まれるのかを明らかにする予定である。また、ATAC-seqにより、細胞周期の変動によってセントロメアクロマチンが大きく変わることが明らかになった。今後、その分子要因を明らかにする予定である。
