In mammalian cells, newly synthesized mRNAs undergo a pioneer round of translation that is important for mRNA quality control. Following maturation of messenger ribonucleoprotein particles during and after the pioneer round, steady-state cycles of mRNA translation generate most of the cell's proteins. Translation factors, RNA-binding proteins, and targets of signaling pathways that are particular to newly synthesized mRNAs regulate critical functions of the pioneer round.
在哺乳动物细胞中,新合成的 mRNA 经历一轮重要的翻译,称为先驱翻译,这对 mRNA 质量控制很重要。信使核糖核蛋白颗粒在先驱翻译期间和之后成熟后,mRNA 翻译的稳态循环产生细胞的大部分蛋白质。特定于新合成的 mRNA 的翻译因子、RNA 结合蛋白和信号通路靶标调节先驱翻译的关键功能。
