Mutant Pvc13-E01-DARPin fused with the DARPin E01 structural domain can enhance the binding ability of PVCs to cells, ultimately enabling targeted delivery of fat proteins. Pvc13-E01-DARPin mutant-based constructs of PVCs particles can specifically target cells with EGFR receptors[1]. In subsequent cell experiments, we used Hela and HEK-293T with high EGFR expression to ensure the targeting of pvc.

Use the CKGGRAKDC to target fat cells.

The different linker(1*GGGSG or 3*GGGSG) on both sides of the CKGGRAKDC can affect the structure and function of the tail protein. By altering the linker on both sides of the CKGGRAKDC, we explored the most suitable structure of the tail protein for recognition and bond. At the same time, because of the existence of linker, we can use Golden Gate to replace the sequences in the middle of linker more efficiently than enzyme cutting and enzyme linking.<br>

pPVC promoter->pvc1-pvc12->pvc13_NTD-2*GGGSG-E01 DARPin-2*GGGSG -pvc13_CTD->pvc14-pvc16

A system for targeted delivery of target proteins.

Profile

Name: pvc1-pvc12、pvc13_NTD-2*GGGSG-E01 DARPin-2*GGGSG -pvc13_CTD、pvc14-pvc16
Origin: Synthetic
Properties: A system for targeted delivery of target proteins.

Usage and Biology

Mutant Pvc13-E01-DARPin fused with the DARPin E01 structural domain can enhance the binding ability of PVCs to cells, ultimately enabling targeted delivery of fat proteins. Pvc13-E01-DARPin mutant-based constructs of PVCs particles can specifically target cells with EGFR receptors[1]. In subsequent cell experiments, we used Hela and HEK-293T with high EGFR expression to ensure the targeting of PVC.
