描述:
Fibroblast growth factor binding protein (FGF-BP), also known as HBp17, is a secreted
glycoprotein that increases the bioavailability of FGFs. Mature FGF-BP is a 34 kDa
Oglycosylated protein with five conserved intrachain disulfide bonds.FGF-BP contains
a heparinbinding domain (aa 113 -146) and a distinct FGFbinding region (aa 197 -238).
Mature rat FGF-BP shares 54% and 81% aa sequence identity with mouse and rat FGF-BP,
respectively. FGF-BP is expressed throughout development and in adult squamous epithelium.
It is upregulated in injured skin, renal tubular epithelium, and spinal nerves as well as in
carcinomas of the skin, colon, and pancreas. FGF-BP binds FGF -1, -2, -7, -10, and-22 which
are secreted and sequestered in the extracellular matrix (ECM). The interactions of FGF-BP
with heparin sulfate proteoglycans (HSPG) and FGF, modulates their activities. FGF-BP
enhances the mitogenic effects of FGFs, thereby contributing to epithelial, endothelial,
and neuronal tissue repair, angiogenesis, and tumor growth.
