Thr-114 is an important functional residue of fibroblast growth factor 10 identified by structure-based mutational analysis.

Fibroblast growth factor 10 (FGF10) plays important roles in vertebrate limb development, lung branching morphogenesis, and epidermis regeneration. The receptor (FGFR2b) binding specificity is an essential element in regulating the diverse functions of FGF10. Analyzing the FGF10:FGFR2b complex we found that Thr-114 in beta4 of FGF10 could form specific… (More)
