CC -!- FUNCTION: Forms the portal vertex of the capsid. This portal plays
CC critical roles in head assembly, genome packaging, neck/tail
CC attachment, and genome ejection. The portal protein multimerizes as a
CC single ring-shaped homododecamer arranged around a central channel.
CC {ECO:0000250|UniProtKB:P03728}.
CC -!- SUBUNIT: Homododecamer. {ECO:0000250|UniProtKB:P03728}.
CC -!- SUBCELLULAR LOCATION: Virion {ECO:0000250|UniProtKB:P03728}.
