Similar to p53 degradation, E6-induced degradation of Scribble is mediated by the ubiquitin ligase E6-AP. In contrast, degradation of Dlg in vitro and within cells has been reported to be independent of E6-AP, suggesting that the E6 oncoprotein has the ability to interact with ubiquitin ligases other than E6-AP. Furthermore, the ability of the E6 oncoprotein to interact with these yet unidentified ubiquitin ligases may be shared by the E6 protein of so-called low risk human papillomaviruses that are not associated with cervical cancer. In this study, we used the RNA interference technology and mouse embryo fibroblasts derived from E6-AP-deficient mice to obtain information about the identity of the ubiquitin ligase(s) involved in E6-mediated degradation of Dlg. We report that, within cells, E6-mediated degradation of Dlg depends on the presence of functional E6-AP and provide evidence that the E6 protein of low risk human papillomaviruses functionally interacts with E6-AP. Based on these data, we propose that, in general, the proteolytic properties of human papillomavirus E6 proteins are mediated by interaction with E6-AP.</dcterms:abstract> <dcterms:bibliographicCitation>Publ. in: The Journal of Biological Chemistry ; 282 (2007), 1. - pp. 65-71</dcterms:bibliographicCitation> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-11-16T08:00:42Z</dcterms:available> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-11-16T08:00:42Z</dc:date> <dc:contributor>Scheffner, Martin</dc:contributor> <dc:contributor>Matentzoglu, Konstantin</dc:contributor> <dcterms:title>The role of the ubiquitin ligase E6-AP in human papillomavirus E6-mediated degradation of PDZ domain-containing proteins</dcterms:title> <dc:creator>Matentzoglu, Konstantin</dc:creator> <dcterms:issued>2007-01-05</dcterms:issued> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/16755"/> <dc:rights>deposit-license</dc:rights> <dc:creator>Kuballa, Petric</dc:creator> <dcterms:rights rdf:resource="http://nbn-resolving.org/urn:nbn:de:bsz:352-20140905103605204-4002607-1"/> <dc:language>eng</dc:language> <dc:contributor>Kuballa, Petric</dc:contributor> </rdf:Description> </rdf:RDF>
