pVEC - a cell penetrating peptide

pVEC (peptide vascular endothelial-cadherin) is a cell-penetrating peptide, which transports proteins through coadministration.

Biology & Usage

It is derived from a segment of the transmembrane domain part of a murine vascular endothelial-cadherin protein, which is involved in cell-cell adhesion. Its ability to enter the cell can mostly be explained by the N-terminal stretch of hydrophobic amino acids, which interact with the plasma membrane.

Characterisation by iGEM Tuebingen 2019

Team iGEM Tuebingen 2019 has added and characterised pVEC by building a software tool which evaluates the penetrability of CPPs, comparing their activity. The results of the characterisation are shown in Fig. 1, where common or new CPPs are shown with their respective penetrability.
