产品介绍

Mirin 一种有效的Mre11-Rad50-Nbs1 (MRN)复合物抑制剂。Mirin 在不影响 ATM 蛋白激酶活性的情况下阻止 ATM (ataxia-telangiectasia mutated) 的 MRN 依赖性激活 (IC₅₀=12 μM)，并抑制 Mre11 相关的核酸外切酶活性。Mirin 可消除哺乳动物细胞中的 G2/M 检查点和同源性依赖性修复。Mirin 在哺乳动物细胞中阻止 ATM 因 DNA 双链断裂 (DSBs) 而激活并阻断同源性定向修复 (HDR)。

生物活性

Mirin is a potentMre11-Rad50-Nbs1 (MRN) complexinhibitor. Mirin prevents MRN-dependent activation ofATM(IC₅₀=12 μM) without affectingATMprotein kinase activity, and it inhibits Mre11-associated exonuclease activity. Mirin abolishes the G2/M checkpoint and homology-dependent repair in mammalian cells. Mirin preventsATMactivation in response to DNA double-strand breaks (DSBs) and blocks homology-directed repair (HDR) in mammalian cells^[1].

体外研究
(In Vitro)

Mirin inhibits H2AX phosphorylation with an IC₅₀of 66 μM. Mirin also inhibits the ATM-dependent phosphorylation of the downstream targets Nbs1 and Chk2 and the MRN-dependent autophosphorylation of ATM at Ser1981 in response to DSBs. Mirin induces a substantial G2 arrest at concentrations of 50 μM and 100 μM. Mirin (10-100 μM) inhibits homology-dependent DNA repair in TOSA4 cells^[1].
BRCA2-deficient cells also showed hypersensitivity to the Mre11 inhibitor Mirin^[2].
