Transcription of DNA into mRNA and translation of mRNA into proteins are two major processes underlying gene expression. Due to the distinct molecular mechanisms, timings, and locales of action, these processes are mainly considered to be independent. During the last two decades, however, multiple factors and elements were shown to coordinate transcription and translation, suggesting an intricate level of synchronization. This review discusses the molecular mechanisms that impact both processes in eukaryotic cells of different origins. The emerging global picture suggests evolutionarily conserved regulation and coordination between transcription and mRNA translation, indicating the importance of this phenomenon for the fine-tuning of gene expression and the adjustment to constantly changing conditions.
DNA 转录成 mRNA 和 mRNA 翻译成蛋白质是基因表达的两个主要过程。由于分子机制、时间和作用位置的不同,这些过程主要被认为是相互独立的。然而,在过去的二十年中,已经发现多种因素和元件可以协调转录和翻译,这表明存在着复杂的同步水平。本综述讨论了影响不同起源的真核细胞中这两个过程的分子机制。新兴的整体图景表明,转录和 mRNA 翻译之间存在着进化上保守的调节和协调,这表明这种现象对于基因表达的精细调控和对不断变化的环境的适应具有重要意义。
