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. During the initial step, a dimer of E1 interacts
CC with a dimer of protein E2 leading to a complex that binds the viral
CC origin of replication with high specificity. Then, a second dimer of E1
CC displaces the E2 dimer in an ATP-dependent manner to form the E1
CC tetramer. Following this, two E1 monomers are added to each half of the
CC site, which results in the formation of two E1 trimers on the viral
CC ori. Subsequently, two hexamers will be created. The double hexamer
CC acts as a bi-directional helicase machinery and unwinds the viral DNA
CC and then recruits the host DNA polymerase to start replication.
CC {ECO:0000255|HAMAP-Rule:MF_04000}.
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 Evidence={ECO:0000255|HAMAP-Rule:MF_04000};
CC -!- SUBUNIT: Can form hexamers. Interacts with E2 protein; this interaction
CC increases E1 DNA binding specificity. Interacts with host DNA
CC polymerase subunit POLA2. Interacts with host single stranded DNA-
CC binding protein RPA1. Interacts with host TOP1; this interaction
CC stimulates the enzymatic activity of TOP1. {ECO:0000255|HAMAP-
CC Rule:MF_04000}.
CC -!- SUBCELLULAR LOCATION: Host nucleus {ECO:0000255|HAMAP-Rule:MF_04000}.
CC -!- PTM: Phosphorylated. {ECO:0000255|HAMAP-Rule:MF_04000}.
CC -!- PTM: Sumoylated. {ECO:0000255|HAMAP-Rule:MF_04000}.
CC -!- SIMILARITY: Belongs to the papillomaviridae E1 protein family.
