Physical interactions between purified HPV His₆-E6 proteins and their cellular targets. Representative immunoblots from GST pull-down assays of the His₆-E6 proteins from HR-HPV16 (a), HR-HPV18 (b), and LR-HPV11 (c) for the GST-fusion proteins for DLG (lanes 2), E6AP (lanes 3), p53 (lanes 4), and PDZ of MAGI-1 (lanes 5). Lanes 1 GST-protein as negative controls, lanes 6 purified His₆-E6 proteins, as positive controls
