CC   -!- FUNCTION: ATP-dependent DNA helicase required for initiation of viral
CC       DNA replication. It forms a complex with the viral E2 protein. The E1-
CC       E2 complex binds to the replication origin which contains binding sites
CC       for both proteins.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + H2O = ADP + H(+) + phosphate; Xref=Rhea:RHEA:13065,
CC         ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616,
CC         ChEBI:CHEBI:43474, ChEBI:CHEBI:456216; EC=3.6.4.12;
CC   -!- SUBCELLULAR LOCATION: Host nucleus.
CC   -!- SIMILARITY: Belongs to the papillomaviridae E1 protein family.
CC       {ECO:0000305}.
