Outline of Final Research Achievements

As a consequence of the analysis of acetaldehyde-induced DNA damage, we found novel regulatory factors of homologous recombination, SWSAP1 and FIGNL1. We also revealed FIGNL1 has an activity to prevent homologous recombination. In addition, the regulation by these proteins is essential for spermatogenesis and oogenesis in mice.

Academic Significance and Societal Importance of the Research Achievements

相同組換えは、異なる染色体同士を組換える機構である。これまでに、飲酒によって生じるアセトアルデヒド依存的なDNA損傷の修復に相同組換えが関与する可能性が示されてきた。本研究では、アセトアルデヒによるDNA損傷の解析を行なった結果、新規の相同組換え制御因子を発見した。本研究で発見した相同組換え制御因子は、既存の制御因子と全く異なる方法で相同組換えを制御しており、新しい相同組換え制御メカニズムを提唱することができた。
