Description:
Fibroblast growth factors (FGFs) require a polysaccharide cofactor, heparin or heparan sulfate (HS), for receptor binding and activation. To probe the molecular mechanism by which heparin or HS (heparin/HS) activates FGF, small nonsulfated oligosaccharides found within heparin/HS were assayed for activity. These synthetic and isomerically pure compounds can activate the FGF signaling pathway. The crystal structures of complexes between FGF and these heparin/HS oligosaccharides reveal several binding sites on FGF and constrain possible mechanisms by which heparin/HS can activate the FGF receptor. These studies establish a framework for the molecular design of compounds capable of modulating FGF activity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ornitz, D M -- Herr, A B -- Nilsson, M -- Westman, J -- Svahn, C M -- Waksman, G -- CA60673/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1995 Apr 21;268(5209):432-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology and Pharmacology, Washington University Medical School, St. Louis, MO 63110, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7536345" target="_blank"〉PubMed〈/a〉
