Inhibition of signal transduction by the binding of non-phosphorylated compositions

摘要

A non-phosphorylated peptide or functionally equivalent composition binds to an SH2 domain of a signal transduction protein with high affinity. In particular, the composition binds to the SH2 domain with an affinity similar to that of at least one phosphorylated peptide that is a natural target for the protein. The inhibition of a signal transduction process can be accomplished by administering a non-phosphorylated peptide or functionally equivalent composition.
