Function
Tyrosine-protein kinase that acts as a cell-surface receptor for VEGFA, VEGFC and VEGFD. Plays an essential role in the regulation of angiogenesis, vascular development, vascular permeability, and embryonic hematopoiesis. Promotes proliferation, survival, migration and differentiation of endothelial cells. Promotes reorganization of the actin cytoskeleton. Isoforms lacking a transmembrane domain, such as isoform 2 and isoform 3, may function as decoy receptors for VEGFA, VEGFC and/or VEGFD. Isoform 2 plays an important role as negative regulator of VEGFA- and VEGFC-mediated lymphangiogenesis by limiting the amount of free VEGFA and/or VEGFC and preventing their binding to FLT4. Modulates FLT1 and FLT4 signaling by forming heterodimers. Binding of vascular growth factors to isoform 1 leads to the activation of several signaling cascades. Activation of PLCG1 leads to the production of the cellular signaling molecules diacylglycerol and inositol 1,4,5-trisphosphate and the activation of protein kinase C. Mediates activation of MAPK1/ERK2, MAPK3/ERK1 and the MAP kinase signaling pathway, as well as of the AKT1 signaling pathway. Mediates phosphorylation of PIK3R1, the regulatory subunit of phosphatidylinositol 3-kinase, reorganization of the actin cytoskeleton and activation of PTK2/FAK1. Required for VEGFA-mediated induction of NOS2 and NOS3, leading to the production of the signaling molecule nitric oxide (NO) by endothelial cells. Phosphorylates PLCG1. Promotes phosphorylation of FYN, NCK1, NOS3, PIK3R1, PTK2/FAK1 and SRC.

- Activity summary
VEGF Receptor 2 also known as KDR or Flk-1 is a receptor tyrosine kinase important for mediating the effects of vascular endothelial growth factor (VEGF). This protein has a mass of approximately 150 kDa. It mostly expresses in vascular endothelial cells playing a primary role in the formation of blood vessels. The receptor can also be found in various non-endothelial tissues though in smaller amounts indicating its broad functional roles outside of the vascular system.
- Biological function summary
VEGF Receptor 2 is important for angiogenesis and vascular permeability. It is part of the VEGF receptor family which also includes VEGF Receptors 1 and 3 forming a complex interaction network. Upon binding with VEGF it phosphorylates key proteins to initiate signals that regulate endothelial cell migration proliferation and survival. The receptor's function is critical for normal developmental processes and wound healing as well.
- Pathways
VEGF Receptor 2 is especially important within the angiogenesis and vascular permeability pathways. It plays a central role in the VEGF signaling pathway alongside proteins like VEGF A which is the primary ligand for the receptor. The signaling through this receptor modulates various downstream proteins through phosphorylation linking it to pathways that control cellular responses essential for blood vessel formation and maintenance.
- Associated diseases and disorders
VEGF Receptor 2 is significantly linked with cancer and age-related macular degeneration. In the context of cancer the overexpression or dysregulation of VEGF and its receptors including VEGF Receptor 2 often leads to enhanced tumor angiogenesis promoting tumor growth and metastasis. Additionally the receptor interacts with other proteins in pathological states such as CD309 in endothelial cell-based assays which are used for research like flow cytometry and ELISA to monitor VEGF Receptor 2 activity and its impact on diseases.
