Ways to unwind with HROB, a new player in homologous recombination
GENES & DEVELOPMENT(2019)
摘要
Homologous recombination (HR) is an important route for repairing DNA double-strand breaks (DSBs). The early stages of HR are well understood, but later stages remain mysterious. In this issue of Genes & Development, Hustedt and colleagues (pp. 1397-1415) reveal HROB as a new player in HR required for recruitment of the MCM8-9 complex, which is paralogous to the MCM2-7 replicative helicase. HROB functions closely with MCM8-9 to promote postsynaptic DNA repair synthesis. This study sheds valuable light on late events in HR and suggests that HROB may load MCM8-9 onto HR intermediates to facilitate the DNA unwinding required for DNA repair synthesis.
