Molecular function

FGF receptor activity, FGF-activated receptor activity, FGFR, fibroblast growth factor-activated receptor activity

Combining with a fibroblast growth factor receptor ligand and transmitting the signal across the plasma membrane to initiate a change in cell activity.

Note that this term represents an activity and not a gene product, and should only be used when the receptor binds the ligand FGF. For receptors that bind other growth factors, consider annotating to terms under 'transmembrane signaling receptor activity ; GO:0004888.
