"Heterodimer with the polymerase; this heterodimer binds to bp 9 to 18 of the genome. Interacts with host POU2F1; POU2F1 binds to the auxiliary sequences in the inverted terminal repeats and tethers the pTP-POL heterodimer to the origin DNA thereby participating in the assembly of the pre-initiation complex (POL-TP-DBP-NFIA-POU2F1)."xsd:string
