FANCM and its relatives, Hef, Mph1 and Fml1, are DNA junction-specific helicases/translocases that target and process perturbed replication forks and intermediates of homologous recombination. They have variously been implicated in promoting the activation of the S-phase checkpoint, recruitment of the Fanconi Anemia Core Complex to sites of DNA damage, crossover avoidance during DNA double-strand break repair by homologous recombination, and the replicative bypass of DNA lesions by template switching. This review summarises our current understanding of the biochemical activities and biological functions of the FANCM family.
FANCM 及其相关蛋白,如 Hef、Mph1 和 Fml1,是 DNA 连接点特异性解旋酶/转位酶,靶向并处理受到干扰的复制叉和同源重组中间体。它们已被广泛认为可以促进 S 期检查点的激活,将范可尼贫血核心复合物募集到 DNA 损伤部位,避免同源重组修复过程中 DNA 双链断裂的交叉,以及通过模板转换进行 DNA 损伤的复制绕过。这篇综述总结了我们目前对 FANCM 家族的生化活性和生物学功能的理解。
