蛋白质紊乱在转录过程中被高度过度代表。蛋白质紊乱可能加速结合、解结合和/或DNA搜索过程。柔性连接、自抑制尾和混杂增强了网络的复杂性。翻译后修饰和变构允许上下文特定的转录。核体含有低复杂度的无序蛋白质和核酸。了解参与转录调控的蛋白质的相互作用对描述生物系统至关重要,因为它们控制着细胞的表达谱。然而遗憾的是,它们属于一种生物物理特征较差的蛋白质子集;它们经常包含高度动态的长无序区域。因此,一个关键问题是,为什么?蛋白质紊乱在转录调控中起什么功能作用?证明这些角色的实验数据开始出现,共同的主题是实现网络的复杂性和快速反应。最近提出了无序在介导无膜细胞器相变中的作用。
HighlightsProtein disorder is highly over-represented within transcriptional processes.Protein disorder may accelerate binding, unbinding and/or DNA search processes.Flexible linkers, auto-inhibitory tails and promiscuity enhance network complexity.Post-translational modification and allostery allow context-specific transcription.Nuclear bodies contain low-complexity disordered proteins and nucleic acids.Understanding the interactions of proteins involved in transcriptional regulation is critical to describing biological systems because they control the expression profile of the cell. Yet sadly they belong to a less well biophysically characterized subset of proteins; they frequently contain long disordered regions that are highly dynamic. A key question therefore is, why? What functional roles does protein disorder play in transcriptional regulation? Experimental data exemplifying these roles are starting to emerge, with common themes being enabling complexity within networks and quick responses. Most recently a role for disorder in mediating phase transitions of membrane-less organelles has been proposed.
