CC -!- FUNCTION: Acts as a ligand for FGFR1, FGFR2, FGFR3 and FGFR4 (By
CC similarity). Also acts as an integrin ligand which is required for FGF2
CC signaling (By similarity). Binds to integrin ITGAV:ITGB3 (By
CC similarity). Plays an important role in the regulation of cell
CC survival, cell division, cell differentiation and cell migration (By
CC similarity). Functions as a potent mitogen in vitro (By similarity).
CC Can induce angiogenesis (By similarity). Mediates phosphorylation of
CC ERK1/2 and thereby promotes retinal lens fiber differentiation (By
CC similarity). {ECO:0000250|UniProtKB:P09038}.
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. Interacts
CC with integrin ITGAV:ITGB3; the interaction is required for FGF2
CC signaling. Interacts with SNORC (via the extracellular domain).
CC Interacts with glypican GPC3. {ECO:0000250|UniProtKB:P09038,
CC ECO:0000250|UniProtKB:P13109, ECO:0000250|UniProtKB:P15655}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:P09038}. Nucleus
CC {ECO:0000250|UniProtKB:P09038}. Note=Exported from cells by an
CC endoplasmic reticulum (ER)/Golgi-independent mechanism (By similarity).
CC Unconventional secretion of FGF2 occurs by direct translocation across
CC the plasma membrane (By similarity). Binding of exogenous FGF2 to FGFR
CC facilitates endocytosis followed by translocation of FGF2 across
CC endosomal membrane into the cytosol (By similarity). Nuclear import
CC from the cytosol requires the classical nuclear import machinery,
CC involving proteins KPNA1 and KPNB1, as well as CEP57 (By similarity).
CC {ECO:0000250|UniProtKB:P09038}.
CC -!- PTM: Phosphorylation at Tyr-82 regulates FGF2 unconventional secretion.
CC {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the heparin-binding growth factors family.
CC {ECO:0000305}.
