General description
17.5 kDa
Fibroblast growth factor 2 (UniProt: P03969; also known as FGF-2, Basic fibroblast growth factor (bFGF), Heparin-binding growth factor 2 (HBGF-2)) is encoded by the FGF2 gene (Gene ID: 281161) in bovine. Fibroblast growth factors (FGFs) are secreted glycoproteins that regulate several fundamental developmental pathways and help regulate mesoderm patterning in the early embryonic development. In adults, FGFs participate in several physiological and pathological processes, including cell proliferation, cell survival, differentiation, wound healing, and regulation of angiogenesis. FGF-2 is synthesized with a propeptide that is subsequently cleaved off to generate the mature active growth factor that can act as a monomer or a homodimer to act as a ligand for FGFR1, FGFR2, FGFR3, and FGFR4. Following its synthesis, it is exported from cells by an endoplasmic reticulum (ER)/Golgi-independent mechanism. Unconventional secretion of FGF-2 occurs by direct translocation across the plasma membrane. It is shown that binding of exogenous FGF-2 to FGF receptors facilitates endocytosis followed by translocation of FGF-2 across endosomal membrane into the cytosol. Its import into nucleus requires the classical nuclear import machinery, involving Karyopherin a1 and b1 and the centrosomal protein 57 (CEP57). FGF-2 expression is observed in granulosa and cumulus cells. It is also expressed in hepatocellular carcinoma cells, but not in non-cancerous liver tissue. FGF-2 is also reported to act as an integrin ligand and binds to integrin aV:b3. This mouse monoclonal bFM-2 antibody can cross-react with native and heat-inactivated basic FGF but will not neutralize biological activity. Anti-FGF-2/basic FGF, neutralizing (Catalog #05-117) is recommended for neutralizing activity. (Ref.: Matsuzaki, K., et al. (1989). Proc Natl Acad Sci USA. 86(24):9911-5; Campos, D.B., et al. (2010).
