ABSTRACT:
The present invention relates to compositions and methods for the prevention, prognostic evaluation, and treatment of oncogenic disorders, especially breast cancer, wherein a protein tyrosine kinase capable of complexing with a member of the SH2-and/or SH3-containing family of adaptor proteins is involved. In a preferred embodiment of the invention, the protein tyrosine kinase is the receptor protein tyrosine kinase HER2 or SHC polypeptide, and the adaptor protein is GRB-7, so that the protein tyrosine kinase/adaptor protein complex is a HER2/GRB-7 complex or a SHC/GRB-7 complex.
