组蛋白赖氨酸甲基化已成为基因表达、细胞周期、基因组稳定性和核结构调控中的关键参与者。在过去的十年中,大量的进展导致了甲基修饰和赖氨酸甲基转移酶(KMT)和赖氨酸脱甲基酶(KDM),调节他们的特点。在这里,我们回顾的发现和表征的KMT和KDM和甲基修饰,他们调节。我们讨论了KMT和KDM的定位以及赖氨酸甲基化在整个基因组中的分布。我们强调这些数据是如何塑造我们的赖氨酸甲基化作为一个复杂的染色质状态的关键决定因素的看法。最后,我们讨论了调节KMT和KDM的蛋白酶体降解,转录后机制和代谢状态。我们提出了该领域的关键问题,并强调了我们预测在未来几年将产生令人兴奋的发现的领域。
Histone lysine methylation has emerged as a critical player in the regulation of gene expression, cell cycle, genome stability, and nuclear architecture. Over the past decade, a tremendous amount of progress has led to the characterization of methyl modifications and the lysine methyltransferases (KMTs) and lysine demethylases (KDMs) that regulate them. Here, we review the discovery and characterization of the KMTs and KDMs and the methyl modifications they regulate. We discuss the localization of the KMTs and KDMs as well as the distribution of lysine methylation throughout the genome. We highlight how these data have shaped our view of lysine methylation as a key determinant of complex chromatin states. Finally, we discuss the regulation of KMTs and KDMs by proteasomal degradation, posttranscriptional mechanisms, and metabolic status. We propose key questions for the field and highlight areas that we predict will yield exciting discoveries in the years to come.
