乙酰化修饰(Acetylation)乙酰化修饰(Acetylation) 蛋白质乙酰化是指将乙酰基通过酶促转移到蛋白质残基上,通常是赖氨酸或甲硫氨酸。组蛋白乙酰化在调控染色质结构和基因转录活性中发挥重要的作用。非组蛋白乙酰化则参与调控蛋白质-蛋白质、蛋白质-DNA和蛋白质-RNA相互作用,蛋白质稳定性,蛋白质活性以及亚细胞定位。乙酰转移酶(如HAT)促进蛋白质乙酰化,而去乙酰化酶(如HDAC)则抑制蛋白质乙酰化(图1)1。 Protein acetylation refers to the enzymatic transfer of acetyl groups to protein residues, usually lysine or methionine. Histone acetylation plays an important role in regulating chromatin structure and gene transcriptional activity. Non histone acetylation is involved in regulating protein-protein, protein-DNA, and protein-RNA interactions, protein stability, protein activity, and subcellular localization. Acetyltransferases (such as HAT) promote protein acetylation, while deacetylases (such as HDAC) inhibit protein acetylation (Fig.1)1.
