RNA聚合酶II终止转录需要两个不同的过程:转录的RNA形成一个确定的3‘端,以及RNA聚合酶从其DNA模板上解离。这两个过程密切相关,在功能信使RNA的生产过程中同样至关重要。然而,近年来的研究已经详细阐述了如何另外使用这两个过程来以定性和定量的方式控制基因表达。这篇综述包含了这些新的发现,并试图描绘一幅更广泛的图景,说明转录周期的最后一步如何对基因调控的许多方面具有至关重要的作用。这篇文章是题为:RNA聚合酶II转录延伸的特刊的一部分。►POL II转录终止和3‘末端加工是两个不同的过程。►终端与3‘端处理是紧密联系、相互影响的。►POL II转录终止采用两条非互斥途径。►向POL II传递的许多线索影响其终止途径的选择。►终止选择受到外部刺激的影响,外部刺激控制着基因的表达。
Termination of transcription by RNA polymerase II requires two distinct processes: The formation of a defined 3′ end of the transcribed RNA, as well as the disengagement of RNA polymerase from its DNA template. Both processes are intimately connected and equally pivotal in the process of functional messenger RNA production. However, research in recent years has elaborated how both processes can additionally be employed to control gene expression in qualitative and quantitative ways. This review embraces these new findings and attempts to paint a broader picture of how this final step in the transcription cycle is of critical importance to many aspects of gene regulation. This article is part of a Special Issue entitled: RNA polymerase II Transcript Elongation. ► Pol II transcription termination and 3′ end processing are different processes. ► Termination and 3′ end processing are intimately connected and influence each other. ► Pol II transcription termination employs two non-mutually exclusive pathways. ► Many cues transmitted to Pol II influence its choice of termination pathway. ► Termination choice is affected by external stimuli, which controls gene expression.
