Part:BBa_K2653001
GFP-nano
The antibody GFP-nano is designed to bind with both Trim21 and the antigen GFP to prove that the P.R.PREDATOR really works. It belongs to the single-chain variable fragment(scFv) family, which has the ability to bind with GFP, but is much smaller than the common antibody of GFP(only 364 bps). In the project GFP-nano successfully bound with target GFP.

Usage and Biology
The GFP-nano works as a core in our system to degrade the proof of concept target GFP as the tool to bind with it. In the design we link GFP-nano with hIgG1-Fc, so that it can work as the bridge between target GFP and Trim21, and finally help form a ternary complex of GFP, GFP-nano and Trim21. Then the E3 ubiquitin ligase Trim21 would tag the complex with the ubiquitin mark, and then employ the proteasome-ubiquitin system to degrade the target GFP protein.
Source
The sequence of GFP-nano we use came from a patent.
