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. Forms homodimers. Interacts with ubiquitin-protein ligase UBE3A/E6-AP; this interaction stimulates UBE3A ubiquitin activity. Interacts with host TP53 and EP300; this interaction inhibits TP53 activity. 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. Belongs to the papillomaviridae E6 protein family. It is uncertain whether Met-1 or Met-3 is the initiator.
