Note: Lacks a cleavable signal sequence. Within the cytoplasm, it is transported to the cell membrane and then secreted by a non-classical pathway that requires Cu2+ ions and S100A13. Secreted in a complex with SYT1. Binding of exogenous FGF1 to FGFR facilitates endocytosis followed by translocation of FGF1 across endosomal membrane into the cytosol. Nuclear import from the cytosol requires the classical nuclear import machinery, involving proteins KPNA1 and KPNB1, as well as LRRC59 (By similarity).By similarity

Subunit structurei
Monomer. Homodimer.
Interacts with FGFR1, FGFR2, FGFR3 and FGFR4. Affinity between fibroblast growth factors (FGFs) and their receptors is increased by heparan sulfate glycosaminoglycans that function as coreceptors.
Found in a complex with FGFBP1, FGF1 and FGF2.
Interacts with FGFBP1.
Part of a Cu2+-dependent multiprotein aggregate containing FGF1, S100A13 and SYT1.
Interacts with SYT1.
Interacts with S100A13 (By similarity).
Interacts with LRRC59 (By similarity).
Interacts with CSNKA, CSNKB and FIBP (By similarity). While binding with LRRC59, CSNKA and FIBP seem mutually exclusive, CSNKB and FIBP may cooperatively interact with FGF1.
Forms a ternary complex with FGFR1 and ITGAV:ITGB3 and induces the recruitment of PTPN11 to the complex (By similarity).
