长链非编码RNA(longnoncodingRNA,lncRNA)是一类重要的普遍存在的基因,参与多种生物学功能。在这里,我们将讨论lncRNA作为信号、诱饵、向导和支架所执行的分子功能的新原型。对于每一个原型,从几个不同的生物学背景的例子说明了分子机制的共性,这些机制的观点提供了有用的解释和生物学结果的预测。这些lncRNA功能的原型可能是一个有用的框架,考虑lncRNA如何获得有用的特性作为生物信号转导,并暗示其可能的起源在进化中。随着新的lncRNA被发现的速度很快,lncRNA的分子机制可能会丰富和多样化。
Long noncoding RNAs (lncRNAs) are an important class of pervasive genes involved in a variety of biological functions. Here we discuss the emerging archetypes of molecular functions that lncRNAs execute—as signals, decoys, guides, and scaffolds. For each archetype, examples from several disparate biological contexts illustrate the commonality of the molecular mechanisms, and these mechanistic views provide useful explanations and predictions of biological outcomes. These archetypes of lncRNA function may be a useful framework to consider how lncRNAs acquire useful properties as biological signal transducers, and hint at their possible origins in evolution. As new lncRNAs are being discovered at a rapid pace, the molecular mechanisms of lncRNAs are likely to be enriched and diversified.
