CC Assembles on the viral origin of replication in an initiation complex CC with viral polymerase, DBP, host NFIA and host POU2F1/OCT1. During CC initiation, the polymerase covalently couples the first dCTP with Ser- CC 580 of pTP. The terminal protein stimulates the template activity over CC 20 fold compared to protein-free templates. Neo-synthesized viral CC genomes are linked to two preterminal proteins, one for each 5' end. CC These new genomes are encapsidated in the nucleus, and during capsid CC maturation by viral protease, preterminal protein is first cleaved into CC intermediary (iTP), then into mature TP. May play a role in host CC nuclear matrix localization of genomic DNA. CC -!- SUBUNIT: Heterodimer with the polymerase; this heterodimer binds to bp CC 9 to 18 of the genome. Interacts with host POU2F1; POU2F1 binds to the CC auxiliary sequences in the inverted terminal repeats and tethers the CC pTP-POL heterodimer to the origin DNA thereby participating in the CC assembly of the pre-initiation complex (POL-TP-DBP-NFIA-POU2F1). CC -!- SUBCELLULAR LOCATION: Host nucleus matrix. CC -!- PTM: Preterminal protein is used to replicate viral genome, upon CC genomic encapsidation it is processed first into iTP and finally into CC TP by adenovirus protease. CC -!- SIMILARITY: Belongs to the adenoviridae terminal protein family.
