Anti-VEGF Receptor-3 Antibody, clone 9D9F9

Vascular endothelial growth factor receptor 3 (UniProt: P35916; also known as EC:2.7.10.1, VEGFR-3, Fms-like tyrosine kinase 4, FLT-4, Tyrosine-protein kinase receptor FLT4) is encoded by the FLT4 (also known as VEGFR3) gene (Gene ID: 2324) in human. FLT-4 is a single-pass type I membrane glycoprotein that is synthesized with a signal peptide (aa 1-24), which is subsequently cleaved off to generate the mature form that contains an extracellular domain (aa 25-775), a transmembrane domain (aa 776-796), and cytoplasmic domain (aa 797-1363). It is expressed in endothelial cells and is also detected in fetal spleen, lung, and brain. In adults it is detected in liver, muscle, thymus, placenta, lung, testis, ovary, prostate, heart, and kidney. FLT-4 has tyrosine-protein kinase activity and acts as a receptor for VEGFC and VEGFD. It plays a role in adult lymphangiogenesis and in the development of the vascular network and the cardiovascular system during embryonic development. Its secreted form functions as a decoy receptor for VEGFC and/or VEGFD and play an important role as a negative regulator of VEGFC-mediated lymphangiogenesis and angiogenesis. Its major function is to promote proliferation, survival, and migration of endothelial cells, and regulates angiogenic sprouting. FLT-4 undergoes trans auto-phosphorylation on tyrosine residues upon ligand binding. Phosphorylation at tyrosine 1068 is required for autophosphorylation at additional tyrosine residues. Phosphorylation at tyrosine 1063 and 1337 are important for interaction with Crk adaptor proteins and subsequent activation of MAPK8. In addition, its phosphorylation at tyrosine 1230, 1231, and 1337 are reported to be important for interaction with Grb2 and subsequent activation of the AKT1 and ERK1/ERK2 signaling pathways.
