PVC13 is a sequence that can encode the tail fibre as the targeting element of the PVC.

Profile
Name:PVC13_NTD-1*EAAAK-CKGGRAKDC-1*EAAAK-PVC13_CTD
Base Pairs: 1362bp
Origin: Photorhabdus, Synthetic
Properties: A sequence used to encode PVC fiber protein
Usage and Biology
PVC13 is a sequence that can encode the tail fibre as the targeting element of the PVC. [1]The PVC fiber protein Pvc13 contains at least 10 repeated motifs resembling the adenovirus fiber and a gp10/gp12 domain, which is probably derived from T4 short tail fiber[2][3]Therefore, it is tempting to speculate that the Pvc13 is another fusion protein derived from the T4 and adenovirus fibers, which may have enabled its recognition of eukaryotic cells.[4]
Sequence CKGGRAKDC is a peptide motif that homes to white fat vasculature.The in vivo localization studies presented show that CKGGRAKDC targets the white adipose vasculature without a detectable preference for any particular anatomical white fat depot. Meanwhile, the motif is preferentially internalized by a receptor in the adipose vasculature that may serve for targeted delivery of therapeutic compounds to fat.[5]
The linker 1*EAAAK on both sides of CKGGRAKDC can affect the function and efficiency of bond and recognition by affecting the structure of the tail protein.(Figure 1)
Special Design
Use the CKGGRAKDC to target fat cells.
The different linker(1*EAAAK or 3*EAAAK) 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.
