The hypotension is mediated by nitric oxide (NO), which is produced by VEGF-activated endothelium NO synthase (PubMed:14600159). Also induces angiogenesis in vitro, probably through VEGF receptor (KDR/VEGFR-2) signaling (PubMed:14600159). May also induce capillary permeability through VEGF receptor (KDR/VEGFR-2) signaling.<ref>PMID:14600159</ref> |

| - | Vascular endothelial growth factor-A (VEGF-A(165)) exerts multiple effects upon binding to the fms-like tyrosine kinase-1 (Flt-1) and the kinase insert domain-containing receptor (KDR). We recently identified two novel snake venom VEGFs (vammin and VR-1) having unique properties. These VEGFs, designated VEGF-Fs, are highly specific ligands for the kinase insert domain-containing receptor and exhibit potent biological activity both in vitro and in vivo when compared with VEGF-A(165). Here, we solved the crystal structures of vammin and VR-1 at 1.9 and 2.0 A resolutions, respectively. Both structures are very similar to each other, and these structures exhibit similar but significantly different features from the known structures of other VEGFs. These differences include a conformational difference in receptor-binding loop 3 caused by an amino acid residue insertion and a difference in surface potential on the possible binding surface for domain 3 of the receptor. These structural differences may be related to the highly selective ligand properties of VEGF-F. | ||
