CC   -!- FUNCTION: May possibly stop tail sheath polymerization by capping the
CC       polymerizing tail sheath once it has reached its requisite length and
CC       prevent its depolymerization. Probably interacts with both the tube and
CC       sheath proteins. {ECO:0000305}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000305}. Host cytoplasm
CC       {ECO:0000305}. Note=Tail. {ECO:0000305}.
CC   -!- INDUCTION: Expressed in the late phase of the viral replicative cycle.
CC       Expression of late genes is activated by the viral late transcription
CC       activator C. {ECO:0000269|PubMed:8293968}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=BAA19194.1; Type=Erroneous initiation; Note=Extended N-terminus.; Evidence={ECO:0000305};
