(GST) COH2-linker(G4S)-TD28REV

This biobrick consists of T7 promotor (BBa_K3633015), RBS (BBa_K4165016), GST (BBa_K4165070), COH2 (BBa_K4165003), G4S linker (BBa_K4165068), TD28REV (BBa_K4165006), Terminator (BBa_K731721), The GST tag was attached to the (COH2-Linker-TD28REV) coding sequence to serve in the purification using Glutathione resin column.

Usage and Biology

The main function is the binding of the tau-binding peptide with the Cohasin protein. It has been used in this project to target and degrade both tau and Aβ proteins which are both considered the main causes of Alzheimer’s Disease pathogenesis.

Modeling

For 2 Models with has score of 5 out of 6 and among 11 Models, we choose our best-ranked model according to its score of 5 out of 6 Q Mean_4 value. Our model values : C Beta deviation = 1 , clash score = 2.74 , molprobity = 1.22 , Ramachandran favored = 97.11 , Ramachandran Outlier = 0.52 , Q Mean_4 = 1.96 , Q Mean_6 = 1.88

Mathematical modeling

Transcription rate and translation rate under T7 promotor

the mathematical modeling was based on our code for the calculation of transcription and translation (you can find it in the code section) beside with the estimated results from the wet lab. 

                   Figure 2. this figure shows the results from the transcription and translation code showing the 
                     variation of mRNA and protein concentrations with time compared with the wet lab results.
