KGF/FGF-7 Protein, Human (His)

KGF/FGF-7 proteins coordinate embryonic development and regulate basic processes such as cell proliferation and differentiation. Its critical role extends to normal branching morphogenesis. KGF/FGF-7 Protein, Human (His) is the recombinant human-derived KGF/FGF-7 protein, expressed by E. coli , with N-His labeled tag.

KGF/FGF-7 Protein assumes a crucial role in orchestrating embryonic development, exhibiting regulatory control over fundamental processes encompassing cell proliferation and differentiation. Its essential contribution extends to the intricate realm of normal branching morphogenesis, where KGF/FGF-7 plays a pivotal role. As a growth factor specifically active on keratinocytes, it emerges as a potential major paracrine effector governing normal epithelial cell proliferation. The protein establishes key interactions, forming complexes with FGFBP1 and FGFR2, and its binding affinity with fibroblast growth factors (FGFs) and their receptors is augmented by heparan sulfate glycosaminoglycans, acting as critical coreceptors in these molecular interactions.

Measured in a cell proliferation assay using 4MBr5 rhesus monkey epithelial cells. The ED₅₀ for this effect is 14.52 ng/mL, corresponding to a specific activity is 6.89×10⁴ units/mg.
