Project Overview

Quorum-sensing coupled with the Repressilator

Our project is a continuation of one of the projects we presented last year: a two-gene oscillator with an 'On' and 'Off' switch using LacI and LuxI. This simple relaxation oscillator could be used as a modular component for the synchronization of other complex oscillating systems such as the repressilator.

Quorum-sensing coupling between cells is achieved with a diffusible autoinducer AI (AHL) made from LuxI which promotes the synthesis of LacI from pLux. As Lac accumulates, it represses pLac which controls the synthesis of LuxI.

-Our project is based on the repressilator system coupled to quorum sensing as described by Jordi Garcia-Ojalvo, Michael B. Elowitz and Steven H. Strogatz in "Modeling a synthetic multicellular clock: Repressilators coupled by quorum sensing" (PNAS). We attempt to visualize the synchronization of the oscillatory phase between cells by the addition of the CFP reporter gene. We expand on this theory by placing cI under the control of pLac, hoping that this would assist in synchronizing the oscillations.

-'''Team 2 - Fluorescence Complimentation'''
+Please feel free to check out our work from last year at [https://2006.igem.org/wiki/index.php/McGill_University iGEM McGill 2006]
-This project on fluorescence complementation involves confirming previous work using Jun and Fos heterodimerizing proteins, each fused to a half terminus of YFP. The two halves of the YFP protein would bind, giving rise to fluorescence.  We will then carry out the experiment with GFP split at different points in order to find a cleavage point that produces ideal results.
