CC   -!- FUNCTION: Essential component of the helicase/primase complex. Unwinds
CC       the DNA at the replication forks and generates single-stranded DNA for
CC       both leading and lagging strand synthesis. The primase initiates primer
CC       synthesis and thereby produces large amount of short RNA primers on the
CC       lagging strand that the polymerase elongates using dNTPs.
CC       {ECO:0000255|HAMAP-Rule:MF_04011}.
CC   -!- SUBUNIT: Associates with the helicase and the primase-associated factor
CC       to form the helicase-primase factor. {ECO:0000255|HAMAP-Rule:MF_04011}.
CC   -!- SUBCELLULAR LOCATION: Host nucleus {ECO:0000255|HAMAP-Rule:MF_04011}.
CC       Note=Requires the presence of the primase associated factor to properly
CC       localize in the host cell nucleus. {ECO:0000255|HAMAP-Rule:MF_04011}.
CC   -!- SIMILARITY: Belongs to the herpesviridae DNA primase family.
CC       {ECO:0000255|HAMAP-Rule:MF_04011}.
