Fibroblast growth factor 2 (FGF-2), also known as basic fibroblast growth factor (bFGF) and FGF-β, is a growth factor and signaling protein encoded by the FGF2 gene. [5] [6] It binds to and exerts effects via specific fibroblast growth factor receptor (FGFR) proteins, themselves a family of closely related molecules.
A mitogenic growth factor activity was found in pituitary extracts by Armelin in 1973 [14] and further work by Gospodarowicz as reported in 1974 described a more defined isolation of proteins from cow brain extract which, when tested in a bioassay that caused fibroblasts to proliferate, led these investigators to apply the name "fibroblast ...
Fibroblast growth factor receptor 2 (FGFR-2) also known as CD332 (cluster of differentiation 332) is a protein that in humans is encoded by the FGFR2 gene residing on chromosome 10. [ 5 ] [ 6 ] FGFR2 is a receptor for fibroblast growth factor .
For example, epidermal growth factor (EGF) enhances osteogenic differentiation (osteogenesis or bone formation), [2] while fibroblast growth factors and vascular endothelial growth factors stimulate blood vessel differentiation (angiogenesis).
The fibroblast growth factor receptors consist of an extracellular ligand domain composed of three immunoglobulin-like domains, a single transmembrane helix domain, and an intracellular domain with tyrosine kinase activity. These receptors bind fibroblast growth factors, members of the largest family of growth factor ligands, comprising 22 ...
The fibroblast growth factor (FGF) family with its prototype members FGF-1 (acidic FGF) and FGF-2 (basic FGF) consists to date of at least 22 known members. [21] Most are single-chain peptides of 16-18 kDa and display high affinity to heparin and heparan sulfate.
