RA   Davis-Poynter N., Nugent J., Birch-Machin I., Allen G.P.;
RL   Submitted (NOV-2003) to the EMBL/GenBank/DDBJ databases.
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}.
CC   -!- SUBUNIT: Homododecamerizes. Interacts with terminase subunits TRM1 and
CC       TRM3. {ECO:0000255|HAMAP-Rule:MF_04012}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000255|HAMAP-Rule:MF_04012}. Host
CC       nucleus {ECO:0000255|HAMAP-Rule:MF_04012}.
CC   -!- SIMILARITY: Belongs to the herpesviridae portal protein family.
CC       {ECO:0000255|HAMAP-Rule:MF_04012}.
