Function
Tyrosine-protein kinase that acts as a cell-surface receptor for VEGFC and VEGFD, and plays an essential role in adult lymphangiogenesis and in the development of the vascular network and the cardiovascular system during embryonic development. Promotes proliferation, survival and migration of endothelial cells, and regulates angiogenic sprouting. Signaling by activated FLT4 leads to enhanced production of VEGFC, and to a lesser degree VEGFA, thereby creating a positive feedback loop that enhances FLT4 signaling. Modulates KDR signaling by forming heterodimers. The secreted isoform 3 may function as a decoy receptor for VEGFC and/or VEGFD and play an important role as a negative regulator of VEGFC-mediated lymphangiogenesis and angiogenesis. Binding of vascular growth factors to isoform 1 or isoform 2 leads to the activation of several signaling cascades; isoform 2 seems to be less efficient in signal transduction, because it has a truncated C-terminus and therefore lacks several phosphorylation sites. Mediates activation of the MAPK1/ERK2, MAPK3/ERK1 signaling pathway, of MAPK8 and the JUN signaling pathway, and of the AKT1 signaling pathway. Phosphorylates SHC1. Mediates phosphorylation of PIK3R1, the regulatory subunit of phosphatidylinositol 3-kinase. Promotes phosphorylation of MAPK8 at 'Thr-183' and 'Tyr-185', and of AKT1 at 'Ser-473'.

Autophosphorylated on tyrosine residues upon ligand binding. Autophosphorylation occurs in trans, i.e. one subunit of the dimeric receptor phosphorylates tyrosine residues on the other subunit. Phosphorylation in response to H(2)O(2) is mediated by a process that requires SRC and PRKCD activity. Phosphorylation at Tyr-1068 is required for autophosphorylation at additional tyrosine residues. Phosphorylation at Tyr-1063 and Tyr-1337 is important for interaction with CRK and subsequent activation of MAPK8. Phosphorylation at Tyr-1230, Tyr-1231 and Tyr-1337 is important for interaction with GRB2 and subsequent activation of the AKT1 and MAPK1/ERK2 and/or MAPK3/ERK1 signaling pathways. In response to endothelial cell adhesion onto collagen, can also be phosphorylated in the absence of FLT4 kinase activity by SRC at Tyr-830, Tyr-833, Tyr-853, Tyr-1063, Tyr-1333, and Tyr-1337.

- Activity summary
VEGF Receptor 3 also known as FLT-4 is a protein essential for lymphatic development and is expressed mainly in lymphatic endothelial cells. This receptor has a molecular mass of approximately 195 kDa. VEGF Receptor 3 belongs to the tyrosine kinase family and binds with high affinity to its ligands VEGF-C and VEGF-D. These interactions lead to the activation of intracellular signaling cascades that promote cell proliferation migration and survival.
- Biological function summary
The VEGF Receptor 3 acts as an important regulator of lymphangiogenesis which is the growth of new lymphatic vessels from pre-existing ones. It is not typically part of larger protein complexes but it works closely with its ligands to facilitate the processes associated with lymph vessel formation and function. Proper activity of VEGF Receptor 3 is necessary for maintaining normal lymphatic vessel remodeling and function during development and in some adult tissues.
- Pathways
The receptor is involved in the VEGF signaling pathway which plays an important role in vascular and lymphatic development. This pathway intersects with others like the PI3K/AKT pathway a critical mediator of cell growth and survival. VEGF Receptor 3 interacts with related receptors such as VEGF Receptor 2 in these pathways to regulate complex and essential physiological processes.
- Associated diseases and disorders
VEGF Receptor 3 has been linked to lymphedema which is swelling due to lymphatic system dysfunction and certain cancers where excessive angiogenesis occurs. Mutations or dysregulations in the receptor's signaling can lead to these conditions. In cancer for instance VEGF Receptor 3 along with its associated protein VEGF-C can promote tumor lymphangiogenesis facilitating metastasis. Antagonists like anti-VEGF therapies target these receptors to inhibit tumor progression and manage these disorders.
