CC -!- FUNCTION: Forms a portal in the viral capsid through which viral DNA is
CC translocated during DNA packaging. Assembles as a dodecamer at a single
CC fivefold axe of the T=16 icosahedric capsid. Binds to the molecular
CC motor that translocates the viral DNA, termed terminase.
CC {ECO:0000255|HAMAP-Rule:MF_04012, ECO:0000269|PubMed:11602732}.
CC -!- SUBUNIT: Homododecamerizes. Interacts with terminase subunits TRM1 and
CC TRM3. {ECO:0000255|HAMAP-Rule:MF_04012, ECO:0000269|PubMed:12743292,
CC ECO:0000269|PubMed:19224991}.
CC -!- SUBCELLULAR LOCATION: Virion {ECO:0000255|HAMAP-Rule:MF_04012,
CC ECO:0000269|PubMed:16920825}. Host nucleus {ECO:0000255|HAMAP-
CC Rule:MF_04012, ECO:0000269|PubMed:12743292}.
CC -!- SIMILARITY: Belongs to the herpesviridae portal protein family.
CC {ECO:0000255|HAMAP-Rule:MF_04012}.
