SH2-containing inositol-phosphatase

摘要

Novel SH2-containing inositol-phosphatase which has a src homology 2 (SH2) domain and exhibits phosphoIns-5-ptase activity, and nucleic acid molecules encoding the novel protein are disclosed. The invention also relates to methods for identifying substances which affect the binding of the protein to Shc and/or its phosphoIns-5-ptase activity and methods for screening for agonists or antagonists of the binding of the protein and Shc.
