The ubiquitously expressed, multifunctional scaffolding proteins β-arrestin1 and β-arrestin2 each affect inflammatory signaling in a variety of cell lines. In addition to binding the carboxyl-terminal tails of innumerable 7-transmembrane receptors, β-arrestins scaffold untold numbers of other plasma membrane and cytoplasmic proteins. Consequently, the effects of β-arrestins on inflammatory signaling are diverse, and context-specific. This review highlights the roles of β-arrestins in regulating canonical activation of the pro-inflammatory transcription factor NFκB.
广泛表达的多功能支架蛋白β-arrestin1 和 β-arrestin2 均可影响多种细胞系中的炎症信号转导。β-arrestin 除了与无数 7 跨膜受体的羧基末端尾巴结合之外,还支架无数其他质膜和细胞质蛋白。因此,β-arrestin 对炎症信号转导的影响是多样化的,且具有特定的上下文依赖性。本综述重点介绍了β-arrestin 在调节促炎转录因子 NFκB 的经典激活中的作用。
