Modelling of GFP expression


Introduction

Here a model for the GFP expression under the control of “The Redoxilator” expression system is derived. The model links the level of the signal molecules NADH and NAD to the final expression of GFP through the events of transcription factor activation, promoter activation, synthesis and degradation of mRNA and finally synthesis, dilution and degradation of GFP.

Abbreviations
TF = the transcription factor based on the REX protein
TF' = active transcription factor
N = concentration of NAD
H = concentration of NADH
TFH = concentration of the transcription factor bound to NADH.
TFN = concentration of the transcription factor bound to NAD.
P = Promoter upstream of GFP
P' = activated/transcribed promoter
tf = fraction of active transcription factor
Pf = fraction of active promoter

Modelling of the redoxilator is in progress...



Modelling facts

Modelling is done using MATLAB with simbiology
