Abstract

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.

Asymmetric Tyrosine Kinase Arrangements in Activation or Autophosphorylation of Receptor Tyrosine Kinases

Journal Article J Bae ; J Schlessinger - Molecules and Cells

Receptor tyrosine kinases (RTKs) play important roles in the control of many cellular processes including cell proliferation, cell adhesion, angiogenesis, and apoptosis. Ligand-induced dimerization of RTKs leads to autophosphorylation and activation of RTKs. Structural studies have shown that while isolated ectodomains of several RTKs form symmetric dimers the isolated cytoplasmic kinase domains of epidermal growth factor receptor (EGFR) and fibroblast growth factor receptor (FGFR) form asymmetric dimers during their activation. Binding of one kinase molecule of EGFR to a second kinase molecule asymmetrically leads to stimulation of kinase activity and enhanced autophosphorylation. Furthermore, the structures of the kinase domain ofmore »« less
A point mutation at tyrosine-809 in the human colony-stimulating factor 1 receptor impairs mitogenesis without abrogating tyrosine kinase activity, association with phosphatidylinositol 3-kinase, or induction of c-fos and junB genes

Journal Article Roussel, M.F. ; Shurtleff, S.A. ; Downing, J.R. ; ... - Proceedings of the National Academy of Sciences of the United States of America; (United States)

Substitution of phenylalanine for tyrosine-809 in the human colony-stimulating factor 1 receptor (CSF-1R) inhibited its ability to transduce ligand-dependent mitogenic signals in mouse NIH 3T3 cells. When combined with an activating mutation at codon 301 that induces constitutive CSF-1R tyrosine kinase activity, the codon 809 mutation suppressed ligand-independent cell transformation. Comparative mapping tryptic phosphopeptides from mutant and wild-type CSF-1R indicated that tyrosine-809 is a site of ligand-dependent receptor phosphorylation in vivo. The mutant receptor was active as a tyrosine kinase in vitro and in vivo, underwent CSF-1-dependent association with a phosphatidylinositol 3-kinase, and induced expression of the protooncogenes c-fos andmore »« less

SGX523 is an exquisitely selective, ATP-competitive inhibitor of the MET receptor tyrosine kinase with antitumor activity in vivo

Journal Article Buchanan, Sean G. ; Hendle, Jorg ; Lee, Patrick S. ; ... - Mol. Cancer Ther.

The MET receptor tyrosine kinase has emerged as an important target for the development of novel cancer therapeutics. Activation of MET by mutation or gene amplification has been linked to kidney, gastric, and lung cancers. In other cancers, such as glioblastoma, autocrine activation of MET has been demonstrated. Several classes of ATP-competitive inhibitor have been described, which inhibit MET but also other kinases. Here, we describe SGX523, a novel, ATP-competitive kinase inhibitor remarkable for its exquisite selectivity for MET. SGX523 potently inhibited MET with an IC{sub 50} of 4 nmol/L and is >1,000-fold selective versus the >200-fold selectivity of othermore »« less

Separate domains of the insulin receptor contain sites of autophosphorylation and tyrosine kinase activity

Journal Article Goren, H.J. ; White, M.F. ; Khan, C.R. - Biochemistry; (United States)

The authors have studied the structure and function of the solubilized insulin receptor before and after partial proteolytic digestion to define domains in the ..beta..-subunit that undergo autophosphorylation and contain the tyrosine kinase activity. Wheat germ agglutinin purified insulin receptor from Fao cells was digested briefly at 22/sup 0/C with low concentrations of trypsin, staphylococcal V8 protease, or elastase. Autophosphorylation of the ..beta..-subunit was carried out before and after digestion, and the (/sup 32/P)phosphoproteins were separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, detected by autoradiography, and analyzed by tryptic peptide mapping by use of reverse-phase high-performance liquid chromatography.

Localization of a human receptor tyrosine kinase (ETK1) to chromosome region 3p11. 2

Journal Article Wicks, I.P. ; Boyd, A.W. ; Lapsys, N.M. ; ... - Genomics; (United States)

The authors have recently described a human receptor tyrosine kinase (hek) that is expressed by some pre-B and thymic T cell lines, but is not detectable on normal adult human tissues. Gene cloning studies established that hek is a new member of the EPH family of receptor tyrosine kinases. The expression of hek may normally be developmentally regulated and inappropriate expression may contribute to oncogenesis. In the present study, they have used Southern blot analysis of somatic cell hybrids and fluorescence in situ hybridization to localize the hek gene to human chromosome region 3p11.2. Karyotype analysis of the cell linesmore »« less
