背景 | Structural maintenance of chromosomes 1 (SMC1) protein is a chromosomal protein member of the cohesin complex that enables sister chromatid cohesion and plays a role in DNA repair (1,2). ATM/NBS1-dependent phosphorylation of SMC1 occurs at Ser957 and Ser966 in response to ionizing radiation (IR) as part of the intra-S-phase DNA damage checkpoint (3). SMC1 phosphorylation is ATM-independent in cells subjected to other forms of DNA damage, including UV light and hydroxyurea treatment (4). While phosphorylation of SMC1 is required for activation of the IR-induced intra-S-phase checkpoint, the precise mechanism is not well understood and may involve a conformational change that affects SMC1-SMC3 interaction (3).染色体结构维持蛋白1(SMC1)是黏连蛋白复合体的一个染色体蛋白成员,该复合体促进姐妹染色单体结合并在DNA修复中起着重要作用(1,2)。作为S期内部DNA损伤检验点的一部分,ATM/NBS1-依赖的SMC1磷酸化发生在第957位和966位丝氨酸以应答离子辐射(IR) (3)。在经历其他形式的DNA损伤包括紫外线和羟基脲处理的细胞中,SMC1的磷酸化是ATM-非依赖的(4)。尽管SMC1的磷酸化是IR诱导的内S期检验点激活所必需的,但精确的机制尚未阐明且有可能涉及影响SMC1-SMC3相互作用的构象变化(3)。 |
