||FGFR2 Kinase (Human) Assay/Inhibitor Screening Assay Kit is a single-site, non-quantitative immunoassay for kinase activity of recombinant catalytic domain of FGFR2. Plates are pre-coated with a newly designed "Tyrosine kinase-substrate-1", which can be easily phosphorylated by recombinant catalytic domain of FGFR2. The detector antibody is PY-39, an antibody that specifically detects the phosphotyrosine residue on "Tyrosine kinase-substrate-1".
||The fibroblast growth factors (FGFs) belong to a family of about 23 related polypeptides. They display biological activity toward cells of mesenchymal, neuronal, and epithelial origin and are involved in processes such as cell growth, organ development, and angiogenesis). The biological effects of FGFs are exerted through interactions with FGF receptors (FGFRs). The receptor family consists of four known members, FGFR1-4, with many isoforms. Upon ligand binding the receptor is thought to be activated through dimerization and phosphorylation by the intracellular tyrosine kinase domains. Heparan sulfate proteoglycans (HSPGs), abundant components of cell surfaces and the extracellular matrix, appear central to signaling through FGF·FGFR complexes.
