'''CRYSTAL STRUCTURE OF FGF1 IN COMPLEX WITH THE EXTRACELLULAR LIGAND BINDING DOMAIN OF FGF RECEPTOR 1 (FGFR1)'''<br />


==Overview==
==CRYSTAL STRUCTURE OF FGF1 IN COMPLEX WITH THE EXTRACELLULAR LIGAND BINDING DOMAIN OF FGF RECEPTOR 1 (FGFR1)==
To elucidate the structural determinants governing specificity in, fibroblast growth factor (FGF) signaling, we have determined the crystal, structures of FGF1 and FGF2 complexed with the ligand binding domains, (immunoglobulin-like domains 2 [D2] and 3 [D3]) of FGF receptor 1 (FGFR1), and FGFR2, respectively. Highly conserved FGF-D2 and FGF-linker (between, D2-D3) interfaces define a general binding site for all FGF-FGFR, complexes. Specificity is achieved through interactions between the, N-terminal and central regions of FGFs and two loop regions in D3 that are, subject to alternative splicing. These structures provide a molecular, basis for FGF1 as a universal FGFR ligand and for modulation of FGF-FGFR, specificity through primary sequence variations and alternative splicing.
