GST-Coh2-G4S- TD28REV
This part consists of the Cohesin 2 module (BBa_K4165003) connected to the tau binding peptide TD28REV (BBa_K4165006) through a flexible linker of GGGGS (BBa_K4165068) repeated 3 times and tagged with a GST tag (BBa_K4165070).
Usage and Biology
The part is considered an integral part of the snitch system in which it directs the Trim21 (E3) ligase to the tau protein in order to force the degradation of tau proteins which causes Alzheimer's Diseases via the proteasomal degradation oathway.

Comparison between chemical lysis and sonication for GST COH TD28 Rev
Figure 4. this graph shows a difference between chemical lysis and sonication for GST COH TD28 Rev, after we had the results we optimized our protocol to use chemical lysis for GST COH (L) TD28 Rev
SDS PAGE of induced and non induced samples of GST COH TD28 Rev
Figure 5. This figure shows the comparison between the induced and non induced samples of GST COH TD28Rev, where well no.2 is the induced sample of GST COH TD28 Rev while well no.6 is the non induced sample of GST COH TD28Rev showing that our protein is induced effectively owing to our right choice of IPTG, time interval and concentration
Pull down assay His Trim (L) DOC against GST COH WWW and GST COH TD28Rev
Figure 6. This graph shows the comparison of pull down assay between His Trim21 (L) DOC with GST COH WWW and GST COH TD28Rev showing that the interaction between His Trim21 (L) DOC and GST COH WWW is better than that of His Trim21 (L) DOC with GAT COH TD28Rev as the concentration of elution of His Trim21 (L) DOC with GST COH WWW is more than that of His trim21 (L) DOC with GST COH TD28Rev
Pull down assay of Tau aggregates against GST COH WWW and GST COH TD28Rev
Figure 7. This graph shows the comparison of pull down assay between Tau aggregates with GST COH WWW and Tau aggregates with GST COH TD28Rev, showing that the interaction between Tau aggregates with GST COH WWW is better than that of Tau aggregates with GST COH TD28rev as the concentration of elution of Tau aggregates with GST COH WWW is more than that of Tau aggregates with GST COH TD28Rev, illustrating that WWW could be a better candidate for binding to the Tau aggregates
