erbB3-composite



Usage and Biology

This part is the key unit of our demonstration part. Besides the necessary promoter CMV and terminator BHG, the composite part BBa_K2653006 is a crucial functional part in the demonstration part of the PR PREDATOR system. The PR PREDATOR is designed to recognize and bind with target proteins, and then recruit the proteasome to deplete the target protein through the ubiquitin-proteasome pathway.
In the demostration, we insert sequence of recombinate scFv of erbB3, which is made up of VL, VH and an improved linker 3XGS into this part, and express the recombinate antibody of erbB3 that includes the scFv and the hIgG1-Fc.

Trim21, the E3 ubiquitin ligase, plays the most important role in the degradation system. The C-terminal B30.2 domain on trim21 offers a site for the conservative Fc region of human IgG 1,2 and 4 to bind with[1]. When the recombinate scFv of erbB3 is linked to the hIgG1-Fc, and after the antibody-antigen interaction, a ternary complex is build up. The trim21 then functions as a E3 ubiquitin ligase and proceeds the complex to be depleted through the ubiquitin-proteasome pathway.
