Abstract Central to cellular transformation caused by human papillomaviruses HPVs is the ability of E6 proteins to target cellular p53 and proteins containing PDZ domains including MAGI-3 for degradation. The aim of this study was to compare E6-mediated degradation of p53 and MAGI-3 under parallel experimental conditions and further with respect to the involvement of proteasomes and ubiquitination. We also compared the degradation of p53 and MAGI-3 by E6 from several HPV types including different variants from HPV-33. All of the E6 genes from different HPV types displayed similar abilities to mediate the .
