Crystal Strucure of FGF Receptor 2 (FGFR2) Kinase Domain Harboring the Pathogenic K641R Mutation Responsible for Pfeiffer Syndrome
|
OverviewOverview
Activating mutations in the tyrosine kinase domain of receptor tyrosine, kinases (RTKs) cause cancer and skeletal disorders. Comparison of the, crystal structures of unphosphorylated and phosphorylated wild-type FGFR2, kinase domains with those of seven unphosphorylated pathogenic mutants, reveals an autoinhibitory "molecular brake" mediated by a triad of, residues in the kinase hinge region of all FGFRs. Structural analysis, shows that many other RTKs, including PDGFRs, VEGFRs, KIT, CSF1R, FLT3, TEK, and TIE, are also subject to regulation by this brake. Pathogenic, mutations activate FGFRs and other RTKs by disengaging the brake either, directly or indirectly.
