Fms-related tyrosine kinase 4 (FLT-4), also known as VEGF-R3, is a tyrosine kinase receptor for vascular endothelial growth factors C and D. The protein is thought to be involved in lymphangiogenesis and maintenance of the lymphatic endothelium. Mutations in this gene cause hereditary lymphedema type IA. Vascular endothelial growth factor receptor-3 (VEGFR-3) and its ligands, vascular endothelial growth factor-C (VEGF-C) and -D (VEGF-D), are the major molecules involved in developmental and pathological lymphangiogenesis. VEGFR3 antibodies specifically stain endothelial cells of lymphatic vessels and vessels around tumonrs such as lymphoma and in situ breast carcinoma.
