Eukaryotic-type DNA polymerase involved in viral genomic replication. DNA synthesis is protein primed, and acts in a strand displacement replication. Assembles in complex with viral pTP, DBP, host NFIA and host POU2F1/OCT1 on viral origin of replication. The polymerase covalently transfers dCMP onto pTP, thereby initiating complementary strand synthesis. a 2'-deoxyribonucleoside 5'-triphosphate + DNA(n) = diphosphate + DNA(n+1) Heterodimer with the terminal protein; this heterodimer binds to bp 9 to 18 of the genome. Forms a complex with viral pTP, DBP and hosts NFIA and POU2F1/OCT1 for initiation of replication. This DNA polymerase requires a protein as a primer. Belongs to the DNA polymerase type-B family.
