ABSTRACT:
The invention relates to novel mutant SH2 domain containing protein tyrosine phosphatases wherein the phosphatase is partially or constitutively active; and whose ability to regulate biological processes are different from the wildtype protein tyrosine phosphatases. The invention also relates to methods of use of the novel mutants, for example, in in vitro assays to screen for binding partners and inhibitors of protein tyrosine phosphatases and in the treatment of protein tyrosine phosphatase mediated diseases or conditions.
