anti-Norovirus GII.4 scFv

This part codes for anti-Norovirus GII.4 scFv (single-chain variable fragment) which derives from human 12A2 antibody. This scFv is suggested to prevent binding of human Norovirus to Hist-Blood Group Antigens[1].
This coding sequence was fused to INPNC-His (BBa_K1933001) or BclA-His (BBa_K1933000) in our project.

Usage and Biology

NoV binding to Histo-blood group antigen (HBGA), expressed on the mucosal epithelium of the digestive tract and/or commensal bacteria, is suggested to be an important part of NoV invasion[2][3]. Also, NoV binding to 12A2 antibody in its HBGA binding site has been demonstrated previously[4]. The scFv coded in our part derives from antibody 12A2, so it also sterically blocks the binding of NoV to HBGA in theory, which might neutralize NoV using the same mechanism employed by human immune system.

We used this part for construction of ☆BBa_K1933200 and BBa_K1933201.
