Abstract

Decades of scientific research have been devoted to unraveling the intricacies of eukaryotic transcription since the groundbreaking discovery of eukaryotic RNA polymerases in the late 1960s. RNA polymerase II, the polymerase responsible for mRNA synthesis, has always attracted the most attention. Despite its structural resemblance to its bacterial counterpart, eukaryotic RNA polymerase II faces a unique challenge in progressing transcription due to the presence of nucleosomes that package DNA in the nuclei. In this review, we delve into the impact of RNA polymerase II and histone signaling on the progression of eukaryotic transcription. We explore the pivotal points of interactions that bridge the RNA polymerase II and histone signaling systems. Finally, we present an analysis of recent cryo-electron microscopy structures, which captured RNA polymerase II-nucleosome complexes at different stages of the transcription cycle. The combination of the signaling crosstalk and the direct visualization of RNA polymerase II-nucleosome complexes provides a deeper understanding of the communication between these two major players in eukaryotic transcription.

合作者还是竞争者:真核生物转录过程中 RNA 聚合酶 II 与核小体之间的交流。
自 20 世纪 60 年代末突破性地发现真核生物 RNA 聚合酶以来,数十年的科学研究一直致力于揭示真核生物转录的复杂性。RNA 聚合酶 II 是负责 mRNA 合成的聚合酶,一直是最受关注的。尽管真核生物 RNA 聚合酶 II 在结构上与细菌的 RNA 聚合酶 II 相似,但由于细胞核中存在包装 DNA 的核小体,真核生物 RNA 聚合酶 II 在转录过程中面临着独特的挑战。在这篇综述中,我们将深入探讨 RNA 聚合酶 II 和组蛋白信号转导对真核生物转录进展的影响。我们探讨了连接 RNA 聚合酶 II 和组蛋白信号系统的相互作用关键点。最后,我们对最近的冷冻电镜结构进行了分析,这些结构捕捉到了转录周期不同阶段的 RNA 聚合酶 II 核小体复合物。信号串扰和 RNA 聚合酶 II 核小体复合物的直接可视化相结合,让我们对真核生物转录过程中这两个主要角色之间的交流有了更深入的了解。

期刊介绍: As the discipline of biochemistry and molecular biology have greatly advanced in the last quarter century, significant contributions have been made towards the advancement of general medicine, genetics, immunology, developmental biology, and biophysics. Investigators in a wide range of disciplines increasingly require an appreciation of the significance of current biochemical and molecular biology advances while, members of the biochemical and molecular biology community itself seek concise information on advances in areas remote from their own specialties. Critical Reviews in Biochemistry and Molecular Biology believes that well-written review articles prove an effective device for the integration and meaningful comprehension of vast, often contradictory, literature. Review articles also provide an opportunity for creative scholarship by synthesizing known facts, fruitful hypotheses, and new concepts. Accordingly, Critical Reviews in Biochemistry and Molecular Biology publishes high-quality reviews that organize, evaluate, and present the current status of high-impact, current issues in the area of biochemistry and molecular biology. Topics are selected on the advice of an advisory board of outstanding scientists, who also suggest authors of special competence. The topics chosen are sufficiently broad to interest a wide audience of readers, yet focused enough to be within the competence of a single author. Authors are chosen based on their activity in the field and their proven ability to produce a well-written publication.
