Designing Allosteric Protein Switches by In Vivo Directed Evolution and Computational Inference

CORDIS · observation · Publication date unknown

iven perspective to fundamentally advance our understanding of protein allostery and accelerate and eventually rationalize the engineering of switchable proteins by interfacing synthetic biology with machine learning. We will establish a 'design by directed evolution' approach to create switchable proteins through receptor and effector fusion followed by phage-assisted in vivo directed evolution using synthetic gene circuits for selection. We will apply this novel pipeline to a diverse set of effector proteins and monitor the evolutionary process by next-generation sequencing (Objective 1). In parallel, we will perform an in-depth computational analysis of domain insertions within the natural protein repertoire. The combined, rich datasets will be used to train machine learning models to infer sequence patterns predictive of domain insertion tolerance and allosteric coupling between receptor-effector pairs (Objective 2). Finally, we will employ this unique model to design light- and drug-inducible variants of the Yamanaka cell reprogramming factors. These will provide the foundation
