传统上,翻译因子被视为驱动核糖体功能并确保 mRNA 准确翻译的蛋白质。最近的发现强调,这些因子也可以兼职基因调控,但其功能不同于它们在蛋白质合成中的典型作用。值得注意的是,翻译因子编码的附加功能多种多样,包括转录控制、细胞外信号传导和 RNA 结合,并且根据外部提示和内在细胞状态而受到高度调节。因此,翻译因子的这种多功能性为精确控制基因表达提供了额外的机制。
Translation factors have been traditionally viewed as proteins that drive ribosome function and ensure accurate mRNA translation. Recent discoveries have highlighted that these factors can also moonlight in gene regulation, but through functions distinct of their canonical roles in protein synthesis. Notably, the additional functions that translation factors encode are diverse, ranging from transcriptional control, extracellular signaling, and RNA-binding, and are highly regulated in response to external cues and intrinsic cellular state. Thus, this multifunctionality of translation factors provides an additional mechanism for exquisite control of gene expression.
