14-3-3 proteins are a family of conserved regulatory adaptor molecules which are expressed in all eukaryotic cells. These proteins participate in a variety of intracellular processes by recognizing specific phosphorylation motifs and interacting with hundreds of target proteins. Also, 14-3-3 proteins act as molecular chaperones, preventing the aggregation of unfolded proteins under conditions of cellular stress. Furthermore, 14-3-3 proteins have been shown to have similar expression patterns in tumors, aging, and neurodegenerative diseases. Therefore, we put forward the idea that the adaptor activity and chaperone-like activity of 14-3-3 proteins might play a substantial role in the above-mentioned conditions. Interestingly, 14-3-3 proteins are considered to be standing at the crossroads of cancer, aging, and age-related neurodegenerative diseases. There are great possibilities to improve the above-mentioned diseases and conditions through intervention in the activity of the 14-3-3 protein family.
14-3-3 蛋白是一组保守的调节衔接分子家族，存在于所有真核细胞中。这些蛋白通过识别特定的磷酸化模体并与数百种靶蛋白相互作用，参与多种细胞内过程。此外，14-3-3 蛋白还可以作为分子伴侣发挥作用，在细胞应激条件下防止未折叠蛋白的聚集。此外，已经证明 14-3-3 蛋白在肿瘤、衰老和神经退行性疾病中有相似的表达模式。因此，我们提出这样的观点，即 14-3-3 蛋白的衔接活性和分子伴侣样活性可能在上述条件中发挥重要作用。有趣的是，14-3-3 蛋白被认为处于癌症、衰老和与年龄相关的神经退行性疾病的十字路口。通过干预 14-3-3 蛋白家族的活性，有很大的可能性改善上述疾病和状况。
