Tumor suppressor DCAF15 inhibits epithelial-mesenchymal transition by targeting ZEB1 for proteasomal degradation in hepatocellular carcinoma
Figure 2. DCAF15 binds with ZEB1 protein. (A–B) Ectopically expressed DCAF15 and ZEB1 can bind with each other. (A) Flag-DCAF15 and Myc-ZEB1 were co-expressed in HEK293T cells, and immunoprecipitated with FLAG-M2 agarose beads. (B) Similar Co-IP assay was performed between Flag-ZEB1 and Myc-DCAF15. (C–D) Endogenous interaction between DCAF15 and ZEB1. (C) SMMC-7721 cells were treated with 10μM MG132 for 6h. Cell lysates were precipitated using anti-ZEB1 antibody or with IgG (mock IP) and coprecipitated DCAF15 was detected by western blotting. (D) SMMC-7721 cells were treated with 10 μM MG132 for 6h. Cell lysates were precipitated using anti-DCAF15 antibody or with IgG (mock IP) and coprecipitated ZEB1 was detected by western blotting. (E) Flag-DCAF15 and Myc-ZEB1 were co-expressed in Hep3B and SMMC-7721 cells respectively and visualized by fluorescence microscopy. Scale bars, 30 μm.
