This project proposes a generic approach for the construction of molecular switches based on artificially autoinhibited proteases. The bottom-up design of protein-based signaling networks is a key goal of synthetic biology. Yet, this remains elusive due to our inability to tailor-make signal transducers and receptors that can be readily compiled into defined signaling networks. Using structure-guided design and directed protein evolution, a set of protease-based signal transducers and ligand activated allosteric receptors will be created. The developed components are intended to be used to construct artificial signaling networks in mammalian cells that are orthogonal to the endogenous signaling cascades.

该项目提出了一种基于人工自抑制蛋白酶构建分子开关的通用方法。基于蛋白质的信号网络的自下而上的设计是合成生物学的一个关键目标。然而，由于我们无法定制可以轻松编译到定义的信号网络中的信号传感器和受体，这仍然难以捉摸。利用结构引导设计和定向蛋白质进化，将创建一组基于蛋白酶的信号转导器和配体激活的变构受体。开发的组件旨在用于在哺乳动物细胞中构建与内源信号级联正交的人工信号网络。
