PFM01 是一种细胞可透过性 N-烷基化 Mirin 衍生物,可选择性抑制 MRE11 核酸内切酶活性,但不抑制核酸外切酶活性。
PFM01 是细胞可透过性 N-烷基化 Mirin(Sigma 货号 475954)衍生物,可选择性抑制 MRE11 核酸内切酶活性,但不抑制核酸外切酶活性。 PFM01 在靠近二聚体界面的位点靶向 MRE11,与 Mirin 和 PFM39 所占用的位点不同,从而可以破坏 ssDNA 结合槽并选择性抑制 MRE11 内切核酸酶活性,但不抑制外切核酸酶活性。 虽然 MRE11 介导的同源重组(HR)修复需要核酸内切酶和核酸外切酶活性,但只有 FM01(100 μM),而不是核酸外切酶抑制剂 Mirin(500 μM)和 PFM39(100 μM),能通过阻断 HR 的启动,在电离辐射(IR)后挽救了 HR 蛋白 BRCA2 缺失的 HSC62-hTERT 成纤维细胞中的 G2 期双链断裂(DSB)修复缺陷,从而可以进行非同源末端连接(NHEJ)。

To maintain stable genomes and to avoid cancer and aging, cells need to repair a multitude of deleterious DNA lesions, which arise constantly in every cell. Processes that support genome integrity in normal cells, however, allow cancer cells to develop

The Mre11A/RAD50/NBN complex (MRN) is an essential regulator of the cellular damage response after DNA double-strand breaks (DSBs). More recent work has indicated that MRN may also impact on the duration of mitosis. We show here that RAD50-deficient fibroblasts exhibit

Homologous recombination (HR) is a major pathway for repair of DNA double-strand breaks (DSBs). The initial step that drives the HR process is resection of DNA at the DSB, during which a multitude of nucleases, mediators, and signaling proteins accumulates
