摘要
Structural data has provided insight into the molecular mechanisms that modulate fibroblast growth factor (FGF) signalling to generate distinct biological outputs in development, tissue homeostasis and metabolism. Mechanisms include alternative splicing of ligand and receptor, homodimerization and site-specific proteolytic cleavage of ligand, and interaction of ligand and receptor with heparan sulphate and Klotho co-receptors. Fibroblast growth factors (FGFs) mediate a broad range of functions in both the developing and adult organism. The accumulated wealth of structural information on the FGF signalling pathway has begun to unveil the underlying molecular mechanisms that modulate this system to generate a myriad of distinct biological outputs in development, tissue homeostasis and metabolism. At the ligand and receptor level, these mechanisms include alternative splicing of the ligand (FGF8 subfamily) and the receptor (FGFR1–FGFR3), ligand homodimerization (FGF9 subfamily), site-specific proteolytic cleavage of the ligand (FGF23), and interaction of the ligand and the receptor with heparan sulphate cofactor and Klotho co-receptor.
