染色质生物学领域一直在加速发展。最近发现了以前未表征的翻译后修饰(PTM)位点和类型,并鉴定了负责这些标记的沉积、去除和阅读的新蛋白质组,这继续提高了已经非常复杂的生物现象的复杂性。在这篇透视文章中,我们研究了组蛋白PTM的新类型和位点的生物学重要性,并总结了新发现的表观遗传读者染色质参与的分子机制。我们还强调了结构的见解在理解PTM-读者相互作用中的重要作用,并讨论了未来的方向,以提高PTM读出的知识。
The field of chromatin biology has been advancing at an accelerated pace. Recent discoveries of previously uncharacterized sites and types of post-translational modifications (PTMs) and the identification of new sets of proteins responsible for the deposition, removal, and reading of these marks continue raising the complexity of an already exceedingly complicated biological phenomenon. In this Perspective article we examine the biological importance of new types and sites of histone PTMs and summarize the molecular mechanisms of chromatin engagement by newly discovered epigenetic readers. We also highlight the imperative role of structural insights in understanding PTM–reader interactions and discuss future directions to enhance the knowledge of PTM readout.
