KDR / VEGFR2 / CD309蛋白背景综述

Vascular endothelial cell growth factor (VEGF), also known as vascular permeability factor, is an endothelial cell mitogen, which stimulates angiogenesis by binding to specific receptors (VEGFRs) on the surface of vascular endothelial cells. The VEGF ligand/receptor signaling system plays a key role in vascular development and regulation of vascular permeability. All the three receptors for VEGF, VEGFR1~3, belong to CSF-1/PDGF receptor subfamily of receptor tyrosine kinase superfamily (RTKs), and contains seven Ig-like C2-type domains in the ECD, as well as a intracellular protein kinase domain. VEGFR2, also called as KDR or Flk-1, is identified as the receptor for VEGF and VEGFC and an early marker for endothelial cell progenitors, whose expression is restricted to endothelial cells in vivo. The adaptor protein SHB has been shown to interact with VEGFR2 in receptor tyrosine kinase signaling. In addition, VEGFR2 is able to interact with HIV-1 extracellular Tat protein upon VEGF activation, and seems to enhance angiogenesis in Kaposi's sarcoma lesions.
