Currently many facets of genetic information are ill-defined. In particular, how protein folding is genetically regulated has been a long-standing issue for genetics and protein biology. And a generic mechanistic model with supports of genomic data is still lacking. Recent technological advances have enabled much needed genome-wide experiments. While putting the effect of codon optimality on debate, these studies have supplied mounting evidence suggesting a role of mRNA structure in the regulation of protein folding by modulating translational elongation rate. In conjunctions with previous theories, this mechanistic model of protein folding guided by mRNA structure shall expand our understandings of genetic information and offer new insights into various biomedical puzzles.
目前,遗传信息的许多方面还没有明确的定义。特别是,蛋白质折叠是如何受到遗传调控的,这一直是遗传学和蛋白质生物学的一个长期问题。并且,仍然缺乏具有基因组数据支持的通用机制模型。最近的技术进步使得全基因组实验成为可能。虽然关于密码子优化的效果仍存在争议,但这些研究提供了越来越多的证据,表明 mRNA 结构在调节翻译延伸率方面在蛋白质折叠的调控中发挥作用。结合以前的理论,这种受 mRNA 结构指导的蛋白质折叠的机制模型将扩展我们对遗传信息的理解,并为各种生物医学难题提供新的见解。
