摘要
真核细胞组蛋白 N端赖氨酸残基的乙酰化与基因的转录激活有关。多种具有组蛋白乙酰化酶 (HAT)和组蛋白去乙酰化酶 (HDAC)活性的调节因子 ,通过对组蛋白乙酰化过程的调节 ,在基因表达调控中发挥着重要作用。HAT和
Acetylation of lysine residues of core histone N terminal domains has been found correlatively associated with transcriptional activation in eukaryotes. Recent studies showed that some transcriptional regulators with histone acetyltransferase(HAT) and deacetylase(HDAC) activities may play a causative role in regulating gene expression. The link between tumorigenic processes and misregulated or mistargeted HAT and HDAC activities has been reported.
