Description
Description: FGFR Human Recombinant produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 363 amino acids (22-376) and having a molecular mass of 40.4kDa. (Molecular size on SDS-PAGE will appear at approximately 40-57kDa). FGFR is fused to a 8 amino acid His-tag at C-terminus & purified by proprietary chromatographic techniques.
Introduction: Fibroblast Growth Factors (FGFs) comprise a family of at least eighteen structurally realted proteins that are involved in a multitude of physiological and pathological cellular processes, including cell growth, differentation, angiogenesis, wound healing and tumorgenesis. The biological activities of the FGFs are mediated by a family if type I transmembrane tyrosine kinases which undergo dimerization and autophosphorylation after ligand binding. Four distinct genes encoding closely related FGF receptors, FGFR-1to-4 are known. Multiple forms of FGFR-1 to-3 are generated by alternative splicing of the mRNAs. A frequent splicing event involving FGFR-1 and-2 results in receptors containing all three Ig domains, referred to as the alpha isoform, or only IgII and IgIII, referred to as the ? isoform. Only the alpha isoform has been identified for FGFR-3 and FGFR-4. Additional splicing events for FGFR-1 to-3, involving the C-terminal half of the IgIII domain encoded by two mutually exclusive alternative exons, generate FGF receptors with alternative IgIII domains (IIIb and IIIc). A IIIa isoform which is a secreted FGF binding protein containing only the N-terminal half of the IgIII domain plus some intron sequences has also been reported for FGFR-1. Mutations in FGFR-1 to-3 have been found in patients with birth defects involving craniosynostosis
