WebTHE MOLECULE. Vascular endothelial growth factor (VEGF) is a heparin-binding, dimeric protein related to the PDGF/sis family of growth factors1. It is a mitogen for endothelial cells, activates and is chemoattractant for monocytes, enhances blood vessel permeability and is a procoagulant 2,3. A homologue of VEGF is encoded by the orf virus 4. All members of the VEGF family stimulate cellular responses by binding to tyrosine kinase receptors (the VEGFRs) on the cell surface, causing them to dimerize and become activated through transphosphorylation, although to different sites, times, and extents. The VEGF receptors have an extracellular portion consisting of 7 immunoglobulin-like domains, a single transmembrane …
