摘要: Fibroblast growth factors (FGFs) are members of a protein family with broad range biological activities. The best characterized FGFs interact two distinct extracellular receptors — transmembrane tyrosine kinase FGF receptor (FGFR) and heparan sulfate-related proteoglycan the matrix. These components form FGF—FGFR—proteoglycan complex that activates FGF-mediated signal transduction process through FGFR dimerization. Recent crystal structure determinations FGF—heparin complexes have provided insights into both interactions between these role heparin-like proteoglycans in function. Future advances this field will benefit enormously from an ability to specifically prepare homogenous heparin-based oligosaccharides defined sequence for use biochemical structural studies many other systems.
