Comments

| Function | Component of the molecular motor that translocates viral genomic DNA in empty capsid during DNA packaging. Forms a tripartite terminase complex together with TRM1 and TRM2 in the host cytoplasm. Once the complex reaches the host nucleus, it interacts with the capsid portal vertex. This portal forms a ring in which genomic DNA is translocated into the capsid. TRM3 carries an RNase H-like nuclease activity that plays an important role for the cleavage of concatemeric viral DNA into unit length genomes. |
| Subunit | Interacts with the terminase subunits TRM1 and TRM2. Interacts with portal protein. |
| Subcellular location | Host nucleus. Note=Responsible for the nuclear localization of the two others subunits TRM1 and TRM2. |
| Similarity | Belongs to the herpesviridae TRM3 protein family. |
