Transcription elongation by RNA polymerase II (RNAP II) involves the coordinated action of numerous regulatory factors. Among these are chromatin-modifying enzymes, which generate a stereotypic and conserved pattern of histone modifications along transcribed genes. This pattern implies a precise coordination between regulators of histone modification and the RNAP II elongation complex. Here I review the pathways and molecular events that regulate co-transcriptional histone modifications. Insight into these events will illuminate the assembly of functional RNAP II elongation complexes and how the chromatin landscape influences their composition and function.
RNA聚合酶II(RNAP II)介导的转录延伸涉及众多调控因子的协同作用。其中包括染色质修饰酶,它们沿转录基因产生刻板且保守的组蛋白修饰模式。这种模式意味着组蛋白修饰调控因子与RNAP II延伸复合物之间存在精确的协调。在此,我综述了调控共转录组蛋白修饰的途径和分子事件。深入了解这些事件将阐明功能性RNAP II延伸复合物的组装,以及染色质景观如何影响其组成和功能。
