HDX-MS analysis of PTPN2 with the CRBN/DDB1 complex

We used HDX-MS analysis to analyze the interaction between PTPN2 with a compound both in the presence and absence of the CRBN/DDB1 complex. We identified significant changes in HDX when PTPN2 was in the presence of compound. We also identified significant changes when comparing the deuteration profiles of PTPN2 in the presence of compound with and without the CRBN/DDB1 complex.
