CC   -!- FUNCTION: Plays an essential role in tail assembly by capping the
CC       rapidly polymerizing tail once it has reached its requisite length and
CC       serving as the interaction surface for the connector and the tail tube
CC       proteins. {ECO:0000250|UniProtKB:D3WAC9}.
CC   -!- SUBUNIT: Homohexamer. Interacts with the tail tube protein.
CC       {ECO:0000250|UniProtKB:D3WAC9}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000250|UniProtKB:D3WAC9}.
CC       Note=Located at the interface with the connector and the tail tube.
CC       {ECO:0000250|UniProtKB:D3WAC9}.
CC   -!- SIMILARITY: Belongs to the Skunalikevirus tail terminator protein
CC       family. {ECO:0000305}.
