These are pathological conditions that develop in numerous tissues and organs as a consequence of diabetes mellitus. They include diabetic retinopathy, diabetic nephropathy leading to end-stage renal disease, and diabetic neuropathy. Diabetic retinopathy remains the major cause of new-onset blindness among diabetic adults. It is characterized by vascular permeability and increased tissue ischemia and angiogenesis. | ||

Induces endothelial cell proliferation, promotes cell migration, inhibits apoptosis and induces permeabilization of blood vessels. Binds to the FLT1/VEGFR1 and KDR/VEGFR2 receptors, heparan sulfate and heparin. NRP1/Neuropilin-1 binds isoforms VEGF-165 and VEGF-145. Isoform VEGF165B binds to KDR but does not activate downstream signaling pathways, does not activate angiogenesis and inhibits tumor growth.<ref>PMID:11427521</ref> <ref>PMID:15520188</ref> <ref>PMID:16489009</ref> | ||

| + | Vascular endothelial growth factor (VEGF) is a homodimeric hormone that induces proliferation of endothelial cells through binding to the kinase domain receptor and the Fms-like tyrosine kinase receptor (Flt-1), the extracellular portions of which consist of seven immunoglobulin domains. We show that the second and third domains of Flt-1 are necessary and sufficient for binding VEGF with near-native affinity, and that domain 2 alone binds only 60-fold less tightly than wild-type. The crystal structure of the complex between VEGF and the second domain of Flt-1 shows domain 2 in a predominantly hydrophobic interaction with the "poles" of the VEGF dimer. Based on this structure and on mutational data, we present a model of VEGF bound to the first four domains of Flt-1. | ||
