Abstract
RNA polymerase II (Pol II) is the multi-protein complex responsible for transcribing all protein-coding messenger RNA (mRNA). Most research on gene regulation is focused on the mechanisms controlling which genes are transcribed when, or on the mechanics of transcription. How global Pol II activity is determined receives comparatively less attention. Here, we follow the life of a Pol II molecule from ‘assembly of the complex’ to nuclear import, enzymatic activity, and degradation. We focus on how Pol II spends its time in the nucleus, and on the two-way relationship between Pol II abundance and activity in the context of homeostasis and global transcriptional changes.
RNA 聚合酶 II(Pol II)是一种多蛋白复合体,负责转录所有编码蛋白质的信使 RNA(mRNA)。有关基因调控的大多数研究都集中在控制哪些基因何时转录的机制或转录的机制上。而 Pol II 的整体活性是如何决定的,则相对关注较少。在这里,我们将跟踪 Pol II 分子从复合组装到核导入、酶活性和降解的全过程。我们的重点是 Pol II 如何在细胞核中度过,以及 Pol II 的丰度和活性在平衡和全局转录变化中的双向关系。
期刊介绍:
BBA Gene Regulatory Mechanisms includes reports that describe novel insights into mechanisms of transcriptional, post-transcriptional and translational gene regulation. Special emphasis is placed on papers that identify epigenetic mechanisms of gene regulation, including chromatin, modification, and remodeling. This section also encompasses mechanistic studies of regulatory proteins and protein complexes; regulatory or mechanistic aspects of RNA processing; regulation of expression by small RNAs; genomic analysis of gene expression patterns; and modeling of gene regulatory pathways. Papers describing gene promoters, enhancers, silencers or other regulatory DNA regions must incorporate significant functions studies.
