Human papillomavirus type 6b
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at protein leveli

Functioni

Plays a major role in the induction and maintenance of cellular transformation. E6 associates with host UBE3A/E6-AP ubiquitin-protein ligase and modulates its activity. Sequesters tumor suppressor TP53 in the host cytoplasm and modulates its activity by interacting with host EP300 that results in the reduction of TP53 acetylation and activation. In turn, apoptosis induced by DNA damage is inhibited. E6 protects also host keratinocytes from apoptosis by mediating the degradation of host BAK1. May also inhibit host immune response.UniRule annotation

Miscellaneous

Belongs to the low risk human alphapapillomavirus family. The cancer-causing human papillomavirus E6 protein has a unique carboxy terminal PDZ domain containing substrate but low risk E6s do not possess this domain.UniRule annotation
