小GTP酶包括人类基因组中超过167种蛋白质的超家族,并且是包括细胞迁移和增殖在内的多种途径的关键调节剂。尽管这些蛋白质在细胞信号传导中的重要性,但缺乏用于控制活细胞内小GTdR活化的标准化方法。在此,我们报告了一种基于分裂蛋白的方法来直接激活活细胞中的小GT3信号传导。重要的是,我们的片段化位点可以应用于小的GTdR超家族。我们通过展示使用用户定义的输入直接调节四种不同的小GTP酶活性的能力来强调这些标准化部件的实用性,提供了第一个用于直接激活活细胞中小GTP酶的即插即用系统。
Small GTPases comprise a superfamily of over 167 proteins in the human genome and are critical regulators of a variety of pathways including cell migration and proliferation. Despite the importance of these proteins in cell signaling, a standardized approach for controlling small GTPase activation within living cells is lacking. Herein, we report a split‐protein‐based approach to directly activate small GTPase signaling in living cells. Importantly, our fragmentation site can be applied across the small GTPase superfamily. We highlight the utility of these standardized parts by demonstrating the ability to directly modulate the activity of four different small GTPases with user‐defined inputs, providing the first plug and play system for direct activation of small GTPases in living cells.
