摘要组蛋白赖氨酸甲基转移酶(HKMT)是一种将甲基存款于组蛋白赖氨酸残基上的酶,在调节染色质结构和基因表达中起重要作用。近几十年来,HKMTs的结构和功能得到了广泛的研究,极大地推进了我们对组蛋白甲基化动态调控的理解。本文综述了具有代表性的HKMTs(H3K4、H3K27、H3K36、H3K79和H4K20甲基转移酶)与核小体复合物的结构研究进展,重点介绍了这些HKMTs与核小体识别和跨组蛋白串扰的分子机制。这些结构研究为HKMT在肿瘤发生中的作用提供了信息,并为开发针对癌症中HKMT的新治疗方法提供了基础。
Abstract Histone lysine methyltransferases (HKMTs) deposit methyl groups onto lysine residues on histones and play important roles in regulating chromatin structure and gene expression. The structures and functions of HKMTs have been extensively investigated in recent decades, significantly advancing our understanding of the dynamic regulation of histone methylation. Here, we review the recent progress in structural studies of representative HKMTs in complex with nucleosomes (H3K4, H3K27, H3K36, H3K79, and H4K20 methyltransferases), with emphasis on the molecular mechanisms of nucleosome recognition and trans-histone crosstalk by these HKMTs. These structural studies inform HKMTs’ roles in tumorigenesis and provide the foundations for developing new therapeutic approaches targeting HKMTs in cancers.
