CC   -!- FUNCTION: Serves as a base for tail tube protein polymerization and
CC       acts as a template for tail length determination. Might remain in the
CC       tube and be ejected from the tail prior to the DNA during DNA ejection
CC       (Potential). {ECO:0000305}.
CC   -!- SUBCELLULAR LOCATION: Host cytoplasm {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   -!- DISRUPTION PHENOTYPE: No tail is synthesized.
CC       {ECO:0000269|PubMed:3904174}.
CC   -!- SIMILARITY: Belongs to the Mulikevirus tape measure protein family.
CC       {ECO:0000305}.
