计算生物学和大规模转录组分析的进展表明,基因组中转录的部分比以前认识的要大得多,导致产生了不同的RNA分子群体,既有蛋白质编码的潜力,也有非编码的潜力。新出现的证据表明,一些RNA分子被错误地注释为非编码,实际上含有编码功能肽的短开放阅读框架(SORF),到目前为止,由于它们的尺寸很小,一直未能被检测到。SORF编码肽或微肽已被证明在基本的生物学过程和维持细胞内稳态方面发挥重要作用。这些小蛋白可以独立发挥作用,例如作为配体或信号分子,或者它们可以通过与较大的调节蛋白接触和调节来发挥其生物学功能。鉴于其体积较小,微肽可能特别适合微调复杂的生物系统。
Advances in computational biology and large-scale transcriptome analyses have revealed that a much larger portion of the genome is transcribed than was previously recognized, resulting in the production of a diverse population of RNA molecules with both protein-coding and non-coding potential. Emerging evidence indicates that a number of RNA molecules have been mis-annotated as non-coding and actually harbor short open reading frames (sORFs) that code for functional peptides, which have evaded detection until now due to their small size. sORF encoded peptides, or micropeptides, have been shown to play important roles in fundamental biological processes and in the maintenance of cellular homeostasis. These small proteins can act independently, for example as ligands or signaling molecules, or they can exert their biological functions by engaging with and modulating larger regulatory proteins. Given their small size, micropeptides may be uniquely suited to fine-tune complex biological systems.
