The peptide stimulates production of VEGF (vascular endothelial growth factor) and HGF (hepatocyte growth factor), both critical for building new capillary networks
Y250 is located much farther from the disulfide bonds (Cys128-Cys206 in the hinge region between K1 and K2 domains, and Cys211-Cys288, Cys232-Cys271, and Cys260-Cys283 in the K2 domain) than the distances between Y198 and disulfide bonds, Cys149-Cys189 and Cys177-Cys201
