14-3-3蛋白是大量表达的接头蛋白,可与大量的结合伙伴相互作用,调节其细胞定位和功能。它们通过多种方式调节底物功能,包括保护底物免受去磷酸化、调节酶活性、形成三元复合体和隔离。因此,14-3-3相互作用伙伴的多样性使14-3-3蛋白能够影响广泛的细胞和生理过程。14-3-3蛋白在大脑中广泛表达,临床和实验研究表明14-3-3蛋白与神经退行性疾病有关。一个反复出现的主题是14-3-3蛋白通过调节靶蛋白的亚细胞定位在发病机制中发挥重要作用。在这里,我们回顾了14-3-3蛋白调节神经退行性疾病的各个方面的证据,重点是它们对神经退行性疾病的保护作用。
14-3-3 proteins are abundantly expressed adaptor proteins that interact with a vast number of binding partners to regulate their cellular localization and function. They regulate substrate function in a number of ways including protection from dephosphorylation, regulation of enzyme activity, formation of ternary complexes and sequestration. The diversity of 14-3-3 interacting partners thus enables 14-3-3 proteins to impact a wide variety of cellular and physiological processes. 14-3-3 proteins are broadly expressed in the brain, and clinical and experimental studies have implicated 14-3-3 proteins in neurodegenerative disease. A recurring theme is that 14-3-3 proteins play important roles in pathogenesis through regulating the subcellular localization of target proteins. Here, we review the evidence that 14-3-3 proteins regulate aspects of neurodegenerative disease with a focus on their protective roles against neurodegeneration.
