Background: The vascular endothelial growth factor receptors (VEGFRs), primarily expressed in the vascular system, are members of the RTK superfamily belonging to the same subclass as receptors for PDGFs and FGFs. The receptors are equipped with an extracellular domain, which is organized into seven immunoglobulin (Ig)-like folds, followed by a single transmembrane region, a juxtamembrane domain, a split tyrosine-kinase domain interrupted by a 70-amino-acid kinase insert, and a C-terminal tail. Binding of VEGFs to the receptor leads to the formation of VEGFR homodimers and heterodimers. The dimerisation of the receptor facilitated an activation of the receptor-kinase by autophosphorylation on multiple tyrosine residues. Phosphorylated receptors recruit interacting proteins and thus induce the activation of several signaling pathways. VEGFR1 is required for the recruitment of haematopoietic precursors and migration of monocytes and macrophages, whereas VEGFR2 and VEGFR3 are essential for the functions of vascular endothelial and lymphendothelial cells, respectively. Upregulation of VEGF in tumor cells and its receptors (VEGFRs) on endothelial cells has been shown to contribute to tumor-associated angiogenesis.
