VEGFA Information: VEGFA Protein, VEGFA Antibody and VEGFA Gene

VEGFA Gene family

VEGFA Protein

VEGFA protein function

Growth factor active in angiogenesis, vasculogenesis and endothelial cell growth. Induces endothelial cell proliferation, promotes cell migration, inhibits apoptosis and induces permeabilization of blood vessels. Binds to the FLT1/VEGFR1 and KDR/VEGFR2 receptors, heparan sulfate and heparin. NRP1/Neuropilin-1 binds isoforms VEGF-165 and VEGF-145. Isoform VEGF165B binds to KDR but does not activate downstream signaling pathways, does not activate angiogenesis and inhibits tumor growth. Binding to NRP1 receptor initiates a signaling pathway needed for motor neuron axon guidance and cell body migration, including for the caudal migration of facial motor neurons from rhombomere 4 to rhombomere 6 during embryonic development (By similarity). {ECO:0000250|UniProtKB:Q00731, ECO:0000269|PubMed:11427521, ECO:0000269|PubMed:16489009}.

VEGFA protein expression

Tissue specificity

Isoform VEGF189, isoform VEGF165 and isoform VEGF121 are widely expressed. Isoform VEGF206 and isoform VEGF145 are not widely expressed. A higher level expression seen in pituitary tumors as compared to the pituitary gland.


By hypoxia. Regulated by growth factors, cytokines, gonadotropins, nitric oxide, hypoglycemia and oncogenic mutations.
