转录调控元件之间的远程相互作用在基因激活、表观遗传沉默和染色质组织中起着重要作用。发育调控基因的转录激活或抑制通常是通过组织特异性染色质结构和激活转录工厂与抑制多梳小体之间的动态定位来完成的。然而,染色质的结构组织和物理相互作用的协调的潜在机制还不完全清楚。绝缘体和多梳状蛋白形成高度保守的多蛋白质复合体,介导功能上的长程相互作用,并被认为在核组织中发挥作用。在这篇综述中,我们探讨了最近的发现,这些发现拓宽了我们对这些蛋白质的功能的理解,并为绝缘体在核组织中的作用提供了一个综合的模型。
Long-range interactions between transcription regulatory elements play an important role in gene activation, epigenetic silencing, and chromatin organization. Transcriptional activation or repression of developmentally regulated genes is often accomplished through tissue specific chromatin architecture and dynamic localization between active transcription factories and repressive Polycomb bodies. However, the mechanisms underlying the structural organization of chromatin and the coordination of physical interactions are not fully understood. Insulators and Polycomb group proteins form highly conserved multi-protein complexes that mediate functional long-range interactions, and have proposed roles in nuclear organization. In this review, we explore recent findings that have broadened our understanding of the function of these proteins and provide an integrative model for the roles of insulators in nuclear organization.
