    摘要: The present invention relates generally to a newly identified adaptor protein FRS2 and related products and methods. FRS2 links protein kinases to activating partners in cells. The invention also relates to nucleic acid molecules encoding portions of FRS2, nucleic acid vectors containing FRS2 related nucleic acid molecules, recombinant cells containing such nucleic acid vectors, polypeptides purified from such recombinant cells, antibodies to such polypeptides, and methods of identifying compounds that enhance or block FRS2 interactions with natural binding partners. Also disclosed are methods for diagnosing abnormal conditions in an organism with FRS2 related molecules or compounds.

    摘要: The invention provides materials, reagents, systems, and methods for identifying agents useful for treating diseases resulting from abnormal (e.g., excessive) FGF receptor signaling. The invention also provides (therapeutic) agents thus identified, and methods of using such agents in treating such diseases. In certain embodiments, the invention relates to the treatment of various craniofacial disorders, or Craniosynostosis, that result from FGFR (e.g. FGFR2) malfunction, such as Crouzon, Apert, Jackson-Weiss, Pfeiffer Syndromes, Crouzon+acanthosis nigricans, Beare-Stevenson cutis gyrata, and non-syndromic craniosynostosis (NS). The methods comprise administering to the individuals a therapeutically effective amount of an inhibitor of the FGFR2c-FRS2 signaling. The inhibitor inhibits signaling by antagonizing FGFR2c-FRS2 interaction, inhibiting the expression and/or subcellular localization of wild-type or mutant FGFR2c and/or FRS2, inhibiting the kinase activity of FGFR2c (e.g. for autophosphorylation and/or phosphorylation of FRS2), and/or inhibiting downstream signaling of FRS2 (such as Sos-Ras-MAPK, Shp2, and/or Gab 1-PI3K pathways).
