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}.
CC   -!- SIMILARITY: Belongs to the podoviridae head-to-tail connector protein
CC       family. {ECO:0000305}.
