Antagonists to bovine pituitary fibroblast growth factor, a l46 amino acid residue polypeptide, are produced. These antagonists are between 4 and 45 residues in length, are characterized by their ability to a) interact with the FGF receptor and/or b) bind heparin and/or c) inhibit and therefore modulate endothelial cell growth. They include either the four residue sequence which forms basic FGF(36-39), namely Pro-Asp-Gly-Arg, or the four residue sequence which constitutes basic FGH(l07-ll0), namely Arg-Ser-Arg-Lys. They are also antagonistic to acidic FGF. |
