Abstract:
Gene regulation networks are essential for the processing of information that cells receive. To study the function and properties of gene regulatory networks synthetic biology is a promising tool. Gene circuits with predefined behaviours have been successfully built and modelled, but largely on a case-by-case basis. We went beyond individual networks and explored both computationally and synthetically the design space of possible dynamical mechanisms for 3-node stripe-forming networks. First, we computationally tested every possible 3-node network for stripe formation in a morphogen gradient. We discovered four different dynamical mechanisms to form a stripe and identified the minimal network of each group. Next, with the help of newly established engineering criteria we built these four networks synthetically and showed that they indeed operate with four fundamentally distinct mechanisms. Finally, this close match between theory and experiment allowed us to infer and subsequently build a 2-node network that represents the archetype of the explored design space.
