英文摘要
Homologous recombination (HR) plays a crucial role in a recovery from stalled replication forks. Our long-term end is to elucidate molecular mechanism of a coupling reaction and a functional inter-play between DNA replication and HR. For this end, we cut into molecular mechanisms of key reactions for HR such as DNA strand exchange reaction and the Holliday intermediate formation. During the period of this study section, we established an in vitro reconstitution system of Swi5-Sfr1-Rad22-Rad51-dependent strand exchange reaction and Holliday junction formation. One of the most important findings is the 3' to 5' direction of formation and branch migration of Holliday junction.
