在哺乳动物中,无义介导的 mRNA 衰减 (NMD) 是一种质量控制机制,可降解含有过早终止密码子的 mRNA,以防止截短蛋白质的合成。为了深入了解 NMD 机制,我们将 NMD 抑制剂 1 (NMDI 1) 确定为 NMD 途径的小分子抑制剂。我们表征了该化合物的作用模式,并证明其作用于 hUPF1 的上游。 NMDI 1 诱导 hSMG5 和 hUPF1 之间相互作用的丧失以及 hUPF1 过度磷酸化亚型的稳定化。将细胞与 NMDI 1 一起孵育,使我们能够证明 NMD 因子和受 NMD 影响的 mRNA 通过加工体(P 体)转运,就像酵母中的情况一样。结果提出了一种模型,其中 mRNA 和 NMD 因子依次被招募到 P 体中。
In mammals, nonsense-mediated mRNA decay (NMD) is a quality-control mechanism that degrades mRNA harboring a premature termination codon to prevent the synthesis of truncated proteins. To gain insight into the NMD mechanism, we identified NMD inhibitor 1 (NMDI 1) as a small molecule inhibitor of the NMD pathway. We characterized the mode of action of this compound and demonstrated that it acts upstream of hUPF1. NMDI 1 induced the loss of interactions between hSMG5 and hUPF1 and the stabilization of hyperphosphorylated isoforms of hUPF1. Incubation of cells with NMDI 1 allowed us to demonstrate that NMD factors and mRNAs subject to NMD transit through processing bodies (P-bodies), as is the case in yeast. The results suggest a model in which mRNA and NMD factors are sequentially recruited to P-bodies.
