Engelsk definition
A fibroblast growth factor receptor with specificity for FIBROBLAST GROWTH FACTORS; HEPARAN SULFATE PROTEOGLYCAN; and NEURONAL CELL ADHESION MOLECULES. Several variants of the receptor exist due to multiple ALTERNATIVE SPLICING of its mRNA. Fibroblast growth factor receptor 1 contains three extracellular IMMUNOGLOBULIN C2-SET DOMAINS and is a tyrosine kinase that transmits signals through the MAP KINASE SIGNALING SYSTEM.
