Target

  • Function

    Plays an important role in the regulation of cell survival, cell division, angiogenesis, cell differentiation and cell migration. Functions as potent mitogen in vitro. Can induce angiogenesis (PubMed:23469107).
  • Tissue specificity

    Expressed in granulosa and cumulus cells. Expressed in hepatocellular carcinoma cells, but not in non-cancerous liver tissue.
  • Sequence similarities

    Belongs to the heparin-binding growth factors family.
  • Post-translational
    modifications

    Phosphorylation at Tyr-215 regulates FGF2 unconventional secretion.
    Several N-termini starting at positions 94, 125, 126, 132, 143 and 162 have been identified by direct sequencing.
  • Cellular localization

    Secreted. Nucleus. Exported from cells by an endoplasmic reticulum (ER)/Golgi-independent mechanism. Unconventional secretion of FGF2 occurs by direct translocation across the plasma membrane. Binding of exogenous FGF2 to FGFR facilitates endocytosis followed by translocation of FGF2 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 CEP57.
