VEGF-A Protein, Pig (His)

The VEGF-A Protein, a versatile growth factor, plays a crucial role in angiogenesis, vasculogenesis, and endothelial cell growth. Its diverse effects include inducing endothelial cell proliferation, promoting cell migration, inhibiting apoptosis, and inducing permeabilization of blood vessels. VEGF-A achieves these functions by binding to receptors FLT1/VEGFR1 and KDR/VEGFR2, as well as heparan sulfate and heparin. Notably, its interaction with the NRP1 receptor initiates a signaling pathway essential for motor neuron axon guidance and cell body migration during embryonic development. Additionally, VEGF-A binds to the DEAR/FBXW7-AS1 receptor, further expanding its regulatory roles. Structurally, VEGF-A exists as a homodimer linked by disulfide bonds and can also form heterodimers with PGF. Interactions with NRP1 and BSG underscore the intricate molecular relationships that underlie the multifaceted functions of VEGF-A in orchestrating vascular processes and embryonic development.
