pCadBA-GFP
This composite part contains the pCadBA promoter (BBa_K3425101) and green fluorescent protein (BBa_E0040). When the CadC domains dimerize, the downstream CadBA promoter will drive green fluorescent protein (GFP) expression.
We recombined pCadBA promoter (BBa_K3425101) and green fluorescent protein (BBa_E0040) by homologous recombination.
With the system above, we selected CadC, promoter CadBA, GFP as our report device. When FXR and RXR dimerize, the linked CadC will be in close proximity and the dimerization occurs, activating promoter CadBA to express GFP.
Finally, we chose FXR and RXR as bile acid sensing receptors, GFP as a signaling device and E. coli BL21 as our chassis organism, hoping to demonstrate the feasibility of our project.
