FGFR2 is a receptor tyrosine kinase in the fibroblast growth factor receptor family. Ligand-dependent activation connects an extracellular signal to intracellular phosphorylation pathways that influence development and cellular behaviour. Alternative receptor isoforms differ in ligand recognition; FGF10 is a ligand for the epithelial FGFR2b isoform. Thus expression of the generic receptor name alone does not specify every ligand response. [ref]
