经过多年的还原论方法来表征参与转录的分子机制后,被认为参与这一过程的因子数量显著增加,而且还在继续增长。当考虑翻译后修饰与调节转录复杂成分的活性所涉及的大量因素一起时,整体的复杂性变得令人震惊。经过20年的密集分子研究,人们一致努力将这些发现与细胞方法相结合,以在更全球的水平上理解转录。这种推理实际上重温了大约20年前的研究,这些研究考虑了类固醇受体与核结构相关的功能后果。随着大量新的分子探针和日益强大的仪器在固定细胞和最近的活细胞中检测它们,功能亚核组织的问题正受到越来越多的关注。在这份报告中,我们重点介绍了转录因子与核骨架相关的功能意义的研究进展。特别是,我们考虑了最近的生物化学和“分子形态”数据,这些数据表明了具有核结构的基因调控因子动态空间和溶解性分配的重要性。J.细胞。生物化学。1998年,70:213-221。©1998 Wiley-Liss,Inc.
After many years of reductionistic approaches to characterize molecular mechanisms involved in transcription, the number of factors recognized to take part in this process has increased remarkably and continues to grow. When considering posttranslational modifications in conjunction with the large number of factors involved in modulating the activity of transcription complex components, the overall intricacy becomes staggering. After two decades of intensive molecular investigations, there has been a concerted effort to integrate these findings with cellular approaches to understand transcription on a more global level. This sort of reasoning actually revisits studies of approximately 20 years ago that considered the functional consequences of steroid receptor association with nuclear structure. With an abundance of new molecular probes and increasingly powerful instruments to detect them in fixed and, more recently, live cells, the issue of functional subnuclear organization is receiving increased attention. In this report, we focus on advances in characterizing the functional significance of transcription factor association with the nucleoskeleton. In particular, we consider recent biochemical and “molecular morphology” data that point to the importance of dynamic spatial and solubility partitioning of gene regulators with nuclear architecture.
