Many cellular proteins form oligomers. The equilibrium between monomeric and oligomeric states of these proteins is important for the regulation of protein activity. Modulation of the oligomerization equilibrium could be an interesting approach in the development of new therapeutic agents. This review summarizes information about protein oligomerization and modulation of this process, demonstrating the role of oligomerization in oncogenesis by tumor suppressor protein p53, which forms tetrameric structure. Today, many studies focus on finding compounds that stabilize its tetramers. Among the methods for studying oligomerization, we present hydrogen/ deuterium exchange method coupled with mass spectrometry which is suitable for the detection of protein-protein interaction and analysis of oligomerization dynamics.
许多细胞蛋白会形成寡聚体。这些蛋白单体状态与寡聚体状态之间的平衡对于蛋白质活性的调节至关重要。调节寡聚化平衡可能是开发新型治疗药物的一个有趣方法。本综述总结了有关蛋白质寡聚化及其过程调节的信息,展示了肿瘤抑制蛋白p53(其形成四聚体结构)的寡聚化在肿瘤发生中的作用。如今,许多研究聚焦于寻找能稳定其四聚体的化合物。在研究寡聚化的方法中,我们介绍了结合质谱的氢/氘交换法,该方法适用于检测蛋白质-蛋白质相互作用以及分析寡聚化动力学。
