MicroRNAs (miRNAs) are ∼22 nt RNAs that direct posttranscriptional repression of mRNA targets in diverse eukaryotic lineages. In humans and other mammals, these small RNAs help sculpt the expression of most mRNAs. This article reviews advances in our understanding of the defining features of metazoan miRNAs and their biogenesis, genomics, and evolution. It then reviews how metazoan miRNAs are regulated, how they recognize and cause repression of their targets, and the biological functions of this repression, with a compilation of knockout phenotypes that shows that important biological functions have been identified for most of the broadly conserved miRNAs of mammals.

后生动物 MicroRNA。

MicroRNA (miRNA) 是~22 nt RNA,可指导不同真核细胞谱系中 mRNA 靶标的转录后抑制。在人类和其他哺乳动物中,这些小 RNA 有助于塑造大多数 mRNA 的表达。本文回顾了我们对后生动物 miRNA 的定义特征及其生物发生、基因组学和进化的理解进展。然后,它回顾了后生动物 miRNA 的调节方式、它们如何识别并导致其靶标的抑制,以及这种抑制的生物学功能,并汇编了敲除表型,表明大多数广泛保守的 miRNA 的重要生物学功能已被识别。哺乳动物。
