生化/生理作用
PFM39 是有效的、细胞可透过性 Mirin 类似物，可选择性抑制 MRE11 核酸外切酶活性，但不抑制核酸内切酶活性。 PFM39 以与 Mirin 相似的方式靶向 MRE11，但与 PFM01 不同，它可以阻断 dsDNA 磷酸骨架的旋转并选择性抑制 MRE11 核酸外切酶活性，但不能抑制核酸内切酶活性。在电离辐射（IR）后，FM39 可能会损害 1BR3-hTERT 成纤维细胞的 G2 相双链断裂（DSB）修复。

Repair of DNA double-strand breaks (DSBs) by homologous recombination (HR) is critical for survival and genome stability of individual cells and organisms, but also contributes to the genetic diversity of species. A vital step in HR is MRN-CtIP-dependent end resection

MRE11 within the MRE11-RAD50-NBS1 (MRN) complex acts in DNA double-strand break repair (DSBR), detection, and signaling; yet, how its endo- and exonuclease activities regulate DSBR by nonhomologous end-joining (NHEJ) versus homologous recombination (HR) remains enigmatic. Here, we employed structure-based design

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
