Fibroblast growth factors (FGFs) are involved in various cellular processes such as cell growth,proliferation, differentiation, migration, angiogenesis, wound healing and embryonic development. Human acidic fibroblast growth factor (hFGF1) binds non-selectively to all the four FGF-receptors and is therefore considered as a powerful mitogen with broadest specificity. However, pharmacological applications of hFGF1 are restricted due to the low thermal stability of the growth factor. hFGF1 has low thermodynamic stability under physiological temperatures which leads to impairment of cellular signaling process thereby preventing its potential mitogenic properties. hFGF1 has a heparin binding pocket at the C-terminus which comprises of positively charges residues. …

Fibroblast growth factors are polypeptide members of the FGF family, which to date comprises of at least 22 members. They belong to a group of growth factors and are involved in a variety of cellular processes including wound healing, angiogenesis, differentiation and development (organogenesis). Amongst FGF members, human acidic FGF-1 and basic FGF-2 are the most characterized. FGF-1 and FGF-2 are known to share more than 80% sequence similarity and have an identical structural fold. However, their biological roles are quite different. FGFs bind to heparin and heparan sulfate ligands through their heparin-binding pockets. The interactions are primarily electrostatic in …
