59 results about "Fibroblast growth factor receptor 4" patented technology

Fibroblast growth factor receptor 4 is a protein that in humans is encoded by the FGFR4 gene. FGFR4 has also been designated as CD334 (cluster of differentiation 334). The protein encoded by this gene is a member of the fibroblast growth factor receptor family, where amino acid sequence is highly conserved between members and throughout evolution. FGFR family members differ from one another in their ligand affinities and tissue distribution. A full-length representative protein would consist of an extracellular region, composed of three immunoglobulin-like domains, a single hydrophobic membrane-spanning segment and a cytoplasmic tyrosine kinase domain. The extracellular portion of the protein interacts with fibroblast growth factors, setting in motion a cascade of downstream signals, ultimately influencing mitogenesis and differentiation. The genomic organization of this gene, compared to members 1-3, encompasses 18 exons rather than 19 or 20. Although alternative splicing has been observed, there is no evidence that the C-terminal half of the IgIII domain of this protein varies between three alternate forms, as indicated for members 1-3. This particular family member preferentially binds acidic fibroblast growth factor and, although its specific function is unknown, it is overexpressed in gynecological tumor samples, suggesting a role in breast and ovarian tumorigenesis.

Mutant polypeptides of fibroblast growth factor 1

The β-trefoil protein human fibroblast growth factor-1 (FGF-1) is made up of a six-stranded anti-parallel β-barrel closed off on one end by three β-hairpins, thus exhibiting a three-fold axis of structural symmetry. The N- and C-termini β-strands hydrogen bond to each other and are postulated from both NMR and X-ray structure data to represent a structurally-weakened region of the β-barrel. Val mutations within the N- and C-termini β-strands are shown to stabilize the structure and to increase van der Waals contacts by filling local cavities present within this region. Mutations that increase van der Waals contacts between both the N- and C-termini β-strands are generally associated with significant reductions in the unfolding kinetics, and also increase the cooperativity of unfolding. Surprisingly, several mutant polypeptides herein disclosed greatly exceed the wild-type polypeptide in ability to stimulate human fibroblasts to proliferate.
