细胞内空间被分隔成单独的隔室,以确保许多生化反应和细胞功能以时空受控的方式发生。包括蛋白质和RNA在内的生物大分子经历液-液相分离和随后的相变,形成具有不同物质状态的生物凝聚物。生物冷凝物的材料/物理性质对于实现其独特的生理功能至关重要,并且异常的材料性质可在病理条件下引起有害影响。在这里,我们回顾了最近的研究表明,在其生理功能的生物冷凝物的材料特性的作用。我们还总结了几个经典的方法,以及新兴的技术表征和/或测量的生物冷凝物的材料特性。
Intracellular spaces are partitioned into separate compartments to ensure that numerous biochemical reactions and cellular functions take place in a spatiotemporally controlled manner. Biomacromolecules including proteins and RNAs undergo liquid–liquid phase separation and subsequent phase transition to form biological condensates with diverse material states. The material/physical properties of biological condensates are crucial for fulfilling their distinct physiological functions, and abnormal material properties can cause deleterious effects under pathological conditions. Here, we review recent studies showing the role of the material properties of biological condensates in their physiological functions. We also summarize several classic methods as well as newly emerging techniques for characterization and/or measurement of the material properties of biological condensates.
