CC -!- FUNCTION: Component of the molecular motor that translocates viral CC genomic DNA in empty capsid during DNA packaging. Forms a tripartite CC terminase complex together with TRM2 and TRM3 in the host cytoplasm. CC Once the complex reaches the host nucleus, it interacts with the capsid CC portal vertex. This portal forms a ring in which genomic DNA is CC translocated into the capsid. TRM1 carries an endonuclease activity CC that plays an important role for the cleavage of concatemeric viral DNA CC into unit length genomes. {ECO:0000256|HAMAP-Rule:MF_04014}. CC -!- SUBUNIT: Associates with TRM2 and TRM3 to form the tripartite terminase CC complex. Interacts with portal protein. {ECO:0000256|HAMAP- CC Rule:MF_04014}. CC -!- SUBCELLULAR LOCATION: Host nucleus {ECO:0000256|HAMAP-Rule:MF_04014}. CC Note=Found associated with the external surface of the viral capsid CC during assembly and DNA packaging, but seems absent in extracellular CC mature virions. {ECO:0000256|HAMAP-Rule:MF_04014}. CC -!- SIMILARITY: Belongs to the herpesviridae TRM1 protein family. CC {ECO:0000256|HAMAP-Rule:MF_04014}.
