摘 要:摘 要:蛋白质翻译后修饰在真核细胞内广泛存在,对生物体发挥调控功能具有重要作用。信号转导及转录激活蛋白(STAT) 家族具有转录激活作用,在细胞应激条件下激活一系列下游靶分子,发挥其调节免疫、细胞增殖和凋亡等功能。STAT 家族蛋白的转录激活需要多种蛋白质翻译后修饰对其功能进行调节,其蛋白质翻译后修饰相互影响,协同调控STAT 家族蛋白的功能。综述了磷酸化、泛素化、乙酰化、甲基化以及类泛素化修饰等不同的翻译后修饰对STAT 功能的影响。

Abstract:

Abstract: Post-translational modifications of proteins are prevailing in eukaryotic cells, which play a significant role in various biological processes. Signal transducers and activators of transcription (STAT) are transcriptional activators that regulate immunity, cell proliferation and apoptosis under stress. The activity of STAT is modulated by different post-translational modifications. In this review, we summarize the functions of various post-translational modifications in regulating STAT activity, including phosphorylation, ubiquitination, acetylation, methylation and ubiquitin-like modification, etc.
