Encompassing Amino Acids: 2-315
Applications: Useful for the study of enzyme kinetics and regulation, to dephosphorylate target substrates and for screening inhibitors.
Assay Conditions: 25 mM Tris-HCl, pH 8.0, 75 mM NaCl, 0.05% Tween-20, 50% glycerol, 2 mM EDTA, 1 mM DTT, and variable glutathione.
Background: Protein tyrosine phosphatase, non-receptor type 2 (PTPN2), is one of the most abundant mammalian tyrosine phosphatase. The protein encoded by this gene is a member of the protein tyrosine phosphatase (PTP) family. By virtue of protein tyrosine phosphatase activity, PTPN2 is known to be a signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation involved in cell communication and signal transduction.
