  • FunctionPlays 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 specificityExpressed in granulosa and cumulus cells. Expressed in hepatocellular carcinoma cells, but not in non-cancerous liver tissue.
  • Sequence similaritiesBelongs 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 localizationSecreted. 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.

Recombinant human FGF2 protein images

  • Human embryonic stem cells (H9) were differentiated both as embryoid bodies and monolayer cultures (on Matrigel) using a protocol described in Kennedy et al., 2007. BMP-4, FGF-basic (ab9596) and VEGF (ab9571) were sequentially added to the media to direct differentiation. These images were taken at day 8, where cell adhesion antigens CD31 (ab32457 in green) and CD34 (ab8536 in red) are abundant and represent primitive haematopoietic cells within the culture. Dapi staining is shown in blue.
  • Standard Curve for FGF basic (Analyte: FGF basic protein (Active) (ab9596)); dilution range 1pg/ml to 1ug/ml using Capture Antibody Mouse monoclonal [AS24] to FGF basic (ab17279) at 1ug/ml and Detector Antibody Rabbit monoclonal [EP1735] to FGF basic (ab92337) at 0.5ug/ml.
