总结了组蛋白精氨酸甲基化修饰体系的最新研究进展.组蛋白精氨酸甲基化修饰在基因转录调控中发挥着十分重要的作用,这类修饰由蛋白精氨酸甲基转移酶(PRMTs)介导,其中PRMT1和PRMT4的甲基化修饰与基因的转录激活作用相关,PRMT5和PRMT6的甲基化修饰则与基因的转录抑制作用相关.组蛋白精氨酸的甲基化是一个动态的可逆过程,催化组蛋白精氨酸的去甲基化是由“精氨酸去甲基化酶”介导的.
Methylation of histone by protein arginine methyltransferases (PRMTs) plays an important role in gene regulation. PRMT1- and PRMT4-catalyzed methyl-arginine is involved in transcription activation, while PRMT5- and PRMT6-catalyzed methyl-arginine is associated with transcription repression. Histone arginine methylation can be dynamically regulated in vivo, and methyl-arginine is demethylated by "arginine demethylase". Here, the most recent progresses in the methylafion studies ofhistone arginine were summarized.
