UBE2D3 interacted with SHP-2 and promoted its ubiquitination. (A) The protein and mRNA levels of SHP-2 in U87 and T98G cells transduced with specific shRNAs. (B) The protein and mRNA levels of SHP-2 in U251 cells with the overexpression of UBE2D3. (C) Co-immunoprecipitation assay using lysates of U87 cells confirmed the interaction between UBE2D3 and SHP-2. (D) The expression of SHP-2 in U251 cells with overexpressed UBE2D3 in the presence of 10 μM MG132 or Vehicle (DMSO). (E) The ubiquitination and expression level of SHP-2 after the transduction of shUBE2D3.
