β-arrestins, which have multiple cellular functions, were initially described as proteins that desensitize rhodopsin and other G protein-coupled receptors. The cytoskeletal system plays a role in various cellular processes, including intracellular transport, cell division, organization of organelles, and cell cycle. The interactome of β-arrestins includes the major proteins of the three main cytoskeletal systems: tubulins for microtubules, actins for the actin filaments, and vimentin for intermediate filaments. β-arrestins bind to microtubules and regulate their activity by recruiting signaling proteins and interacting with assembly proteins that regulate the actin cytoskeleton and the intermediate filaments. Altered regulation of the cytoskeletal system plays an essential role in the development of Alzheimer's, Parkinson's and other neurodegenerative diseases. Thus, β-arrestins, which interact with the cytoskeleton, were implicated in the pathogenesis progression of these diseases and are potential targets for the treatment of neurodegenerative disorders in the future.
β-arrestins 具有多种细胞功能,最初被描述为使视紫红质和其他 G 蛋白偶联受体脱敏的蛋白质。细胞骨架系统在多种细胞过程中发挥作用,包括细胞内运输、细胞分裂、细胞器的组织和细胞周期。β-arrestins 的相互作用组包括三个主要细胞骨架系统的主要蛋白质:微管的微管蛋白、肌动蛋白的肌动蛋白丝和中间丝的波形蛋白。β-arrestins 与微管结合,并通过招募信号蛋白和与调节肌动蛋白细胞骨架和中间丝的组装蛋白相互作用来调节其活性。细胞骨架系统的调节异常在阿尔茨海默病、帕金森病和其他神经退行性疾病的发展中起着至关重要的作用。因此,与细胞骨架相互作用的β-arrestins 被牵连到这些疾病的发病机制进展中,并且是未来治疗神经退行性疾病的潜在靶点。
