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. Protects host keratinocytes
CC       from apoptosis by mediating the degradation of host BAK1. May also
CC       inhibit host immune response. {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 BAK1. {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   -!- SIMILARITY: Belongs to the papillomaviridae E6 protein family.
CC       {ECO:0000255|HAMAP-Rule:MF_04006, ECO:0000305}.
