p53肿瘤抑制因子是一种序列特异性转录因子,其经历了大量的翻译后修饰来调节和激活。p53的乙酰化是一个重要的可逆的酶促过程,发生在响应DNA损伤和遗传毒性应激,是必不可少的p53转录活性。p53是第一个显示被组蛋白乙酰基转移酶乙酰化的非组蛋白蛋白,并且许多最近的体内模型已经强调了这种类型的修饰对p53活性的重要性。在这里,我们回顾了目前的知识和最近的研究结果,p53乙酰化和去乙酰化,并讨论这些过程的p53通路的影响。
The p53 tumor suppressor is a sequence-specific transcription factor that undergoes an abundance of post-translational modifications for its regulation and activation. Acetylation of p53 is an important reversible enzymatic process that occurs in response to DNA damage and genotoxic stress and is indispensible for p53 transcriptional activity. p53 was the first non-histone protein shown to be acetylated by histone acetyl transferases, and a number of more recent in vivo models have underscored the importance of this type of modification for p53 activity. Here, we review the current knowledge and recent findings of p53 acetylation and deacetylation and discuss the implications of these processes for the p53 pathway.
