| Popis: | The E6 proteins from the high-risk human papillomavirus (HPV) types have previously been shown to target a number of PDZ domain-containing proteins for proteasome-mediated degradation. These include the hDlg tumour suppressor and the MAGI-1 protein. In this study we show that high-risk HPV E6 proteins also target the related MAGI-2 and MAGI-3 proteins for degradation. Moreover, we show that the interaction is specific to one PDZ domain, and that co-expression of this domain can protect each of the full-length MAGI proteins from E6-mediated degradation. These data provide clear indicators for the potential design of compounds that could specifically inhibit the interaction of oncogenic HPV E6 proteins with an important class of target proteins. |
