RNA 结合蛋白 HuR(人类抗原 R)与大量编码和非编码转录本相关,并控制它们的剪接、定位、稳定性和翻译。通过对靶转录本的调节,HuR 与细胞事件有关,包括增殖、衰老、分化、细胞凋亡以及应激和免疫反应。反过来,HuR 会影响癌症和炎症等过程。 HuR 功能主要通过翻译后修饰来调节,这些修饰改变其亚细胞定位及其结合靶 RNA 的能力;这些修饰包括磷酸化、甲基化、泛素化、NEDDylation 和蛋白水解切割。在这篇综述中,我们描述了影响基因表达程序和疾病状态的 HuR 功能的修饰。
The RNA-binding protein HuR (human antigen R) associates with numerous transcripts, coding and noncoding, and controls their splicing, localization, stability, and translation. Through its regulation of target transcripts, HuR has been implicated in cellular events including proliferation, senescence, differentiation, apoptosis, and the stress and immune responses. In turn, HuR influences processes such as cancer and inflammation. HuR function is primarily regulated through posttranslational modifications that alter its subcellular localization and its ability to bind target RNAs; such modifications include phosphorylation, methylation, ubiquitination, NEDDylation, and proteolytic cleavage. In this review, we describe the modifications that impact upon HuR function on gene expression programs and disease states.
