Description

Vascular endothelial cell growth factors (VEGFs) are secreted polypeptides with a highly conserved cystine-knot structure similar to that of the platelet-derived growth factors (PDGFs).  VEGFs play important roles in vascular development and in diseases involving abnormal growth of blood vessels such as tumor-related angiogenesis. VEGFs stimulate angiogenesis by binding to the specific receptors (VEGFRs) on the surface of vascular endothelial cells. All the three VEGFRs, VEGFR1 (Flt-1), VEGFR2 (KDR/Flk-1/CD309), and VEGFR3 (Flt-4), belong to the CSF-1/PDGF receptor subfamily of receptor tyrosine kinase superfamily (RTKs). Each VEGFR contains 7 immunoglobulin (Ig)-like C2-type domains in the extracellular region and an intracellular kinase domain. VEGFR3 is widely expressed in the early embryo but restricted to lymphatic vessels at later stages of development. VEGFR3 is up-regulated in tumor angiogenesis. VEGFC and VEGFD have been identified as ligands for VEGFR3. VEGFR3 plays a significant role in ligand-mediated lymphangiogenesis. Mutation in this gene is associated with the primary lymphedema, a rare genetic condition with both autosomal dominant and autosomal recessive modes of inheritance. The VEGFR3-mediated signaling pathway may provide a target for anti-lymphangiogenic therapy in cancer.

Construct Details: The recombinant human FLT4-Fc fusion is expressed as a 525 amino acid protein consisting of Tyr25 - Thr323 region of FLT4 and a C-terminal Fc from human IgG1, which exists as a dimer under non-reducing conditions.

 

Source:  Human cells stably expressing FLT4-Fc and growing in chemical-defined media with no animal components or antibiotics.
