Abstract

Chromosomal surfaces are ornamented with a variety of post-translational modifications of histones, which are required for the regulation of many of the DNA-templated processes. Such histone modifications include acetylation, sumoylation, phosphorylation, ubiquitination, and methylation. Histone modifications can either function by disrupting chromosomal contacts or by regulating non-histone protein interactions with chromatin. In this review, recent findings will be discussed regarding the regulation of the implementation and physiological significance for one such histone modification, histone H3 lysine 4 (H3K4) methylation by the yeast COMPASS and mammalian COMPASS-like complexes.

摘要

染色体表面装饰有多种组蛋白的翻译后修饰,这些修饰是许多以DNA为模板的过程调控所必需的。此类组蛋白修饰包括乙酰化、SUMO化、磷酸化、泛素化和甲基化。组蛋白修饰可以通过破坏染色体接触或通过调节非组蛋白与染色质的相互作用来发挥作用。在本综述中,将讨论关于酵母COMPASS和哺乳动物COMPASS样复合物对一种此类组蛋白修饰——组蛋白H3赖氨酸4(H3K4)甲基化的调控及其生理意义的最新研究结果。
