就像所有物质一样,蛋白质也可以在气相、液相和固相之间转换。蛋白质相变是近年来研究细胞如何区室化和调节生化反应的一种新方法。此外,这一发现为研究神经退行性疾病中的无膜细胞器生物发生和蛋白质聚集提供了新的框架。我们现在认为,这个框架可能是有用的细胞周期调控和癌症的研究。基于我们对神经退行性变中富含精氨酸的蛋白质相变的研究,通过将质谱与生物信息学分析相结合,我们发现许多参与细胞周期调控的蛋白质也可以经历蛋白质相分离。事实上,最近已经发现,其功能影响细胞周期或与癌症相关的几种蛋白质从试管到细胞的相分离。研究这一过程对细胞周期蛋白的作用并了解其分子基础将为细胞周期进展和癌症的生物学提供关键的见解。
Just like all matter, proteins can also switch between gas, liquid and solid phases. Protein phase transition has claimed the spotlight in recent years as a novel way of how cells compartmentalize and regulate biochemical reactions. Moreover, this discovery has provided a new framework for the study of membrane-less organelle biogenesis and protein aggregation in neurodegenerative disorders. We now argue that this framework could be useful in the study of cell cycle regulation and cancer. Based on our work on phase transitions of arginine-rich proteins in neurodegeneration, via combining mass spectroscopy with bioinformatics analyses, we found that also numerous proteins involved in the regulation of the cell cycle can undergo protein phase separation. Indeed, several proteins whose function affects the cell cycle or are associated with cancer, have been recently found to phase separate from the test tube to cells. Investigating the role of this process for cell cycle proteins and understanding its molecular underpinnings will provide pivotal insights into the biology of cell cycle progression and cancer.
