A Systematic Analysis of Human Papillomavirus (HPV) E6 PDZ Substrates Identifies MAGI-1 as a Major Target of HPV Type 16 (HPV-16) and HPV-18 Whose Loss Accompanies Disruption of Tight Junctions

Abstract excerpt

The E6 proteins from high-risk, cancer-causing types of human papillomavirus (HPV) are characterized by the presence of a PDZ (PSD95/Dlg/ZO-1) binding motif in their extreme carboxy termini, through which they interact with a number of cellular PDZ domain-containing substrates. In order to ascertain how many of these are degraded by E6 in vivo, we performed an extensive analysis of the effects of E6 ablation on...
