Studies show that CKGGRAKDC the motif is preferentially internalized by a receptor in the adipose vasculature that may serve for targeted delivery of therapeutic compounds to fat.[1]Also, studies prove that on-native payloads can be loaded into PVC particles.[2]Together, by reason of pvc13 forms the tail fiber and the validation of the experiments that recombinant PVCs are biologically active against cultured insect cells and can be reprogrammed to both load and deliver non-native proteins into target cells to yield novel biological activities.[3]

pVc13_NTD-CKGGRAKDC-pvc13_CTD

A component assembled from tail fiber and nonapeptide that targets fat cells.

Profile

Name: pvc13_NTD-CKGGRAKDC-pvc13_CTD
Base Pairs: 1332bp
Origin: Synthetic
Properties: A component assembled from tail fiber and nonapeptide that targets fat cells

Usage and Biology

Studies show that CKGGRAKDC the motif is preferentially internalized by a receptor in the adipose vasculature that may serve for targeted delivery of therapeutic compounds to fat.[1]Also, studies prove that on-native payloads can be loaded into PVC particles.[2]Together, by reason of pvc13 forms the tail fiber and the validation of the experiments that recombinant PVCs are biologically active against cultured insect cells and can be reprogrammed to both load and deliver non-native proteins into target cells to yield novel biological activities.(Figure 1)[3]
