CC   -!- FUNCTION: Functions as a docking protein to recruit essential
CC       components of the viral replication machinery to viral DNA origins. In
CC       the presence of the major DNA-binding protein, opens dsDNA leading to a
CC       conformational change in the origin that facilitates DNA unwinding and
CC       subsequent replication (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Homodimer. Interacts with the major DNA-binding protein.
CC       Interacts with the DNA helicase/primase complex-associated protein and
CC       the polymerase accessory protein (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Host nucleus {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the herpesviridae OriBP family. {ECO:0000305}.
