EGF Receptor Substrate 2 (Phospho-Tyr5) is a biologically active peptide derived from an autophosphorylation site (Tyr992) of epidermal growth factor receptor (EGFR).
DADEpYLIPQQG is a generalized PTPase substrate. Both CAV GST-VP2 and TLMV GST-ORF2 are shown to have PTPase activity using both ENDpYINASL and DADEpYLIPQQG. Steady state activities for the reaction of 5 μg of CAV GST-VP2 with ENDpYINASL and DADEpYLIPQQG are 100 and 208%, respectively, of those seen for 2 units of TC-PTP[1]. In the context of DADEpYLIPQQG, the minimal sizes recognized by PTPα are either ADEpYLI or DADEpY-NH2. The kcat/Km value for the parent peptide DADEpYLIPQQG (EGFR988-998) is 1090-fold higher than Tyr(P)[2].

Kinase experiment: | Briefly, the assays are performed in 50 μL volumes in a microtiter plate using the generalized PTPase substrates ENDpYINASL and DADEpYLIPQQG (where pY represents phosphotyrosine) and assay buffer containing 25 mM Tris-HCl (pH 7.4), 50 mM NaCl, 2 mM EDTA, 5 mM dithiothreitol, 0.01% Brij 35, and 1 mg of bovine serum albumin/mL. The reactions are started by the addition of 5 μg of either CAV GST-VP2, GST, CAV GST-VP2 containing the C95S mutation, or TLMV GST-ORF2 or 2 units of the positive control T cell protein-tyrosine phosphatase (TC-PTP) in assay buffer. Control reactions are assayed with either ENDpYINASL substrate alone, DADEpYLIPQQG substrate alone, CAV GST-VP2 without substrate, CAV GST-VP2 containing the C95S mutation without substrate, TLMV GST-ORF2 without substrate, TC-PTP without substrate, or assay buffer with neither enzyme nor substrate. A phosphate standard curve is derived using a supplied phosphate standard. The reactions are terminated by the addition of the malachite green detection reagent. |
