CC   -!- FUNCTION: Plays a major role in the induction and maintenance of
CC       cellular transformation. E6 associates with host UBE3A/E6-AP ubiquitin-
CC       protein ligase and modulates its activity. Sequesters tumor suppressor
CC       TP53 in the host cytoplasm and modulates its activity by interacting
CC       with host EP300 that results in the reduction of TP53 acetylation and
CC       activation. In turn, apoptosis induced by DNA damage is inhibited. E6
CC       protects also host keratinocytes from apoptosis by mediating the
CC       degradation of host BAK1. May also inhibit host immune response.
CC       {ECO:0000255|HAMAP-Rule:MF_04006}.
CC   -!- SUBUNIT: Forms homodimers. Interacts with ubiquitin-protein ligase
CC       UBE3A/E6-AP; this interaction stimulates UBE3A ubiquitin activity.
CC       Interacts with host TP53 and EP300; this interaction inhibits TP53
CC       activity. {ECO:0000255|HAMAP-Rule:MF_04006}.
CC   -!- SUBCELLULAR LOCATION: Host cytoplasm {ECO:0000255|HAMAP-Rule:MF_04006}.
CC       Host nucleus {ECO:0000255|HAMAP-Rule:MF_04006}.
CC   -!- MISCELLANEOUS: Belongs to the low risk human alphapapillomavirus
CC       family. The cancer-causing human papillomavirus E6 protein has a unique
CC       carboxy terminal PDZ domain containing substrate but low risk E6s do
CC       not possess this domain. {ECO:0000255|HAMAP-Rule:MF_04006}.
CC   -!- SIMILARITY: Belongs to the papillomaviridae E6 protein family.
CC       {ECO:0000305}.
