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:0000255|HAMAP-Rule:MF_04014}.
CC -!- SUBUNIT: Associates with TRM2 and TRM3 to form the tripartite terminase
CC complex. Interacts with portal protein. {ECO:0000255|HAMAP-
CC Rule:MF_04014}.
CC -!- SUBCELLULAR LOCATION: Host nucleus {ECO:0000255|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:0000255|HAMAP-Rule:MF_04014}.
CC -!- SIMILARITY: Belongs to the herpesviridae TRM1 protein family.
CC {ECO:0000255|HAMAP-Rule:MF_04014}.
