Outline of Research at the Start

中西はツメガエル卵抽出液を用いた生化学的や培養細胞を用いた細胞生物学的、鵜木はICF細胞を用いた細胞生物学的、藤は植物を用いた遺伝学的手法を利用し、DNAメチル化によるラギング鎖複製制御機構を解明する。具体的には、UHRF1依存的なラギング鎖合成制御の分子機構について、(1) UHRF1とLIG1の相互作用制御ドメインの同定と結合制御機構の解明や、DNA複製ストレス存在下におけるLIG1リクルート制御機構の解析、(2) UHRF1除去による岡崎フラグメント連結異常(連結効率、フラグメント長、配置)の解析、(3) ICF細胞におけるLIG1制御機構の解析を中心に実施する。

Outline of Final Research Achievements

Nakanishi revealed the molecular mechanisms of DNA maintenance methylation. He also revealed the molecular structural basis of UHRF1 inhibition by mDPPA3. He found that CDCA7 could bind specifically to hemimethylated DNA on nucleosomes and succeeded in clarifying the details of its binding structural mode. He also reported that histone H3 ADP ribosylation by the PARP1/HPF1 complex is LIG3-dependent. Unoki identified a role for CDCA7 and HELLS in ICF syndrome. Fuji discovered a novel plant-specific non-CpG methylation mechanism.

Academic Significance and Societal Importance of the Research Achievements

世界で初めてDNA維持メチル化機構の全貌を明らかにしたことは学術的意義が非常に深い。またDNA維持メチル化機構の解明は、老化やその他ヒト疾患の理解にも繋がることからその社会的意義も深い。実際、鵜木によるCDCA7A/HELLSによるDNA維持メチル化機構の解析は、ヒトのICF症候群の理解に強く結びついた。藤の見出した植物特異的非CpGメチル化の分子基盤の解明は、今後哺乳動物細胞におけるDNAメチル化機構の解明に有用と考えられ、その学術的意義は高い。
