The present disclosure is based on the surprising and unexpected discovery that a ligand molecule with certain characteristics is able to bind to two protein molecules simultaneously and recruit them to form a transient or stable protein-protein interaction complex. The protein-protein interaction and other cross-domain interactions gained in this process contribute additional stabilization energy to the complex beyond the combination of the binary binding energies, and therefore, largely increase the binding potency of the ligand. Accordingly, the present disclosure provides a Protein-Protein Interaction Inducing Technology (PPIIT), which includes a method to design and identify the tripartite or bifunctional compounds and use such compounds to induce protein-protein interactions in various contexts. The present disclosure also provides a composition for the purpose of inducing protein-protein interactions.
本公开基于一个惊人且意想不到的发现,即具有特定特征的配体分子能够同时结合两个蛋白质分子,并招募它们形成瞬时或稳定的蛋白质-蛋白质相互作用复合物。在这个过程中获得的蛋白质-蛋白质相互作用和其他跨领域相互作用为复合物提供了额外的稳定能量,超越了二元结合能的组合,因此大大增加了配体的结合效能。因此,本公开提供了一种蛋白质-蛋白质相互作用诱导技术(PPIIT),其中包括一种设计和识别三部分或双功能化合物的方法,并使用这些化合物在各种情境中诱导蛋白质-蛋白质相互作用。本公开还提供了一种用于诱导蛋白质-蛋白质相互作用的组合物。
