Figure Lengend Snippet: CP681301 treatment destabilized E6, reduced E6AP and rescued p53. (A). HeLa and C33A cell lines were treated with CP681301 at the concentrations of 0.6 μM and 1.5 μM for 24 h. The protein extracts were subjected to Western blotting for the detection of CDK5, 18E6, E6AP, p53, and β-actin proteins. (B). CP681301 disrupted the 18E6-E6AP protein complex. The inhibition of CP681301 was detected using the GST-pull down assay, where CP681301 was incubated with the purified GST-18E6 protein and Flag-E6AP protein for 2h. After extensive washing, the bound E6AP protein was detected via Western blotting using an anti-Flag antibody. The immunoblot (IB) on the upper panel shows the interaction of E6AP with GST-18E6, while the lower panel shows the Ponceau S stained of the blot.
