水通道蛋白(AQP)是维持细胞内水平衡的膜蛋白。人AQP与其他蛋白质之间的相互作用通过门控和运输在AQP调节中起着至关重要的作用。在这里,我们描述了一个协议之间的相互作用的特点,人类水通道蛋白和可溶性相互作用的合作伙伴,使用微尺度热泳(MST)。MST具有低样品消耗和高去污剂相容性的优点,使得能够在对组分和环境进行高水平控制的情况下进行AQP蛋白质-蛋白质相互作用研究。有关本方案使用和执行的完整详细信息,请参见和。微量热泳法测定AQP蛋白质-蛋白质相互作用量化在亚纳摩尔至毫摩尔范围内的亲和力的相互作用优点是样品消耗量低和广泛的相容性水通道蛋白水通道(AQP)是维持细胞水稳态的膜蛋白。人AQP与其他蛋白质之间的相互作用通过门控和运输在AQP调节中起着至关重要的作用。在这里,我们描述了一个协议之间的相互作用的特点,人类水通道蛋白和可溶性相互作用的合作伙伴,使用微尺度热泳(MST)。MST具有低样品消耗和洗涤剂相容性的优点,使得能够在对组分和环境进行高水平控制的情况下进行AQP蛋白质-蛋白质相互作用研究。
Aquaporin water channels (AQPs) are membrane proteins that maintain cellular water homeostasis. The interactions between human AQPs and other proteins play crucial roles in AQP regulation by both gating and trafficking. Here, we describe a protocol for characterizing the interaction between a human AQP and a soluble interaction partner using microscale thermophoresis (MST). MST has the advantage of low sample consumption and high detergent compatibility enabling AQP protein-protein interaction investigation with a high level of control of components and environment. For complete details on the use and execution of this protocol, please refer to and.
