Product Description |
Recombinant Human FGFR2 beta (IIIb) Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Pro154-Leu358. |
Product Background |
Four distinct genes encoding closely related FGF receptors, FGF R1 - 4, are known. All four genes for FGF Rs encode proteins with an N-terminal signal peptide, three immunoglobulin (Ig)-like domains, an acid-box region containing a run of acidic residues between the IgI and IgII domains, a transmembrane domain and the split tyrosine-kinase domain. Multiple forms of FGF R1 - 3 are generated by alternative splicing of the mRNAs. A frequent splicing event involving FGF R1 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 beta- isoform. |
