ABSTRACT:
Modified SH2 domains of intracellular proteins and methods of use, wherein the SH2 domains are modified to include an altered binding site for a signal transduction protein. The binding site is altered to either change the specificity of the SH2 domain for a signal transduction protein that is not the natural ligand or to include a reactive group, such as a reactive amino acid, that reacts with a phosphorylated amino acid of the signal transduction protein. The modified SH2 domains are useful as research tools or in methods for inactivating or inhibiting signal transduction proteins, especially those that contribute to disease or disorders such as cancer or for targeting specific SH2 domains for diagnostics.
