CC -!- FUNCTION: Acts as a ligand for FGFR1, FGFR2, FGFR3 and FGFR4 CC (PubMed:8663044). Also acts as an integrin ligand which is required for CC FGF2 signaling (PubMed:28302677). Binds to integrin ITGAV:ITGB3 CC (PubMed:28302677). Plays an important role in the regulation of cell CC survival, cell division, cell differentiation and cell migration CC (PubMed:8663044, PubMed:28302677). Functions as a potent mitogen in CC vitro (PubMed:1721615, PubMed:3964259, PubMed:3732516). Can induce CC angiogenesis (PubMed:23469107, PubMed:28302677). Mediates CC phosphorylation of ERK1/2 and thereby promotes retinal lens fiber CC differentiation (PubMed:29501879). {ECO:0000269|PubMed:1721615, CC ECO:0000269|PubMed:29501879, ECO:0000269|PubMed:3732516, CC ECO:0000269|PubMed:3964259}. CC -!- BIOPHYSICOCHEMICAL PROPERTIES: CC pH dependence: CC Retains almost half of its activity after treatment at pH 2.0 for 3 CC hours at 20 degrees Celsius. {ECO:0000269|PubMed:1721615}; CC Temperature dependence: CC Inactivated after 3 minutes at 60 degrees Celsius or 1 minute at 80 CC degrees Celsius. {ECO:0000269|PubMed:1721615}; CC -!- SUBUNIT: Monomer. Homodimer. Interacts with FGFR1, FGFR2, FGFR3 and CC FGFR4. Affinity between fibroblast growth factors (FGFs) and their CC receptors is increased by heparan sulfate glycosaminoglycans that CC function as coreceptors. Interacts with CSPG4, FGFBP1 and TEC. Found in CC a complex with FGFBP1, FGF1 and FGF2. Interacts with FGFBP3 CC (PubMed:18669637). Interacts with integrin ITGAV:ITGB3; the interaction CC is required for FGF2 signaling (PubMed:28302677).

Nucleus CC {ECO:0000269|PubMed:22321063}. Note=Exported from cells by an CC endoplasmic reticulum (ER)/Golgi-independent mechanism. Unconventional CC secretion of FGF2 occurs by direct translocation across the plasma CC membrane (PubMed:20230531). Binding of exogenous FGF2 to FGFR CC facilitates endocytosis followed by translocation of FGF2 across CC endosomal membrane into the cytosol (PubMed:22321063). Nuclear import CC from the cytosol requires the classical nuclear import machinery, CC involving proteins KPNA1 and KPNB1, as well as CEP57 (PubMed:22321063).
