The past decade has revolutionized our understanding of regulatory noncoding RNAs (ncRNAs). Among the most recently identified ncRNAs are downstream-of-gene (DoG)-containing transcripts that are produced by widespread transcriptional readthrough. The discovery of DoGs has set the stage for future studies to address many unanswered questions regarding the mechanisms that promote readthrough transcription, RNA processing, and the cellular functions of the unique transcripts. In this review, we summarize current findings regarding the biogenesis, function, and mechanisms regulating this exciting new class of RNA molecules.
过去十年,我们对调控性非编码 RNA(ncRNA)的理解发生了革命性变化。在最近鉴定的 ncRNA 中,有一种是基因下游转录本(DoG),它们由广泛的转录通读产生。DoG 的发现为未来的研究奠定了基础,这些研究将解决许多关于促进通读转录、RNA 加工以及这些独特转录本的细胞功能的机制的未解答问题。在这篇综述中,我们总结了关于这些令人兴奋的新 RNA 分子的生物发生、功能和调控机制的现有发现。
