CC   -!- FUNCTION: Serves as a ruler that controls the length of tail by
CC       stopping the tail tube polymerization and is probably released from the
CC       tail shaft during infection to facilitate DNA translocation into the
CC       host cell. Assembles into a multimeric linear form probably arranged as
CC       a coil of alpha-helices and stabilized by the covering tail assembly
CC       proteins. Its C-terminus fixes the tail tip complex, thereby forming
CC       the tail assembly initiator complex. Tail tube proteins polymerize
CC       around the tape measure protein, displacing the tail assembly proteins.
CC       When the tail reaches the length specified by the tape measure protein,
CC       it stops and becomes capped by the tail terminator protein.
CC       {ECO:0000255|HAMAP-Rule:MF_04138}.
CC   -!- SUBUNIT: Interacts with the tail initiator complex presumably through
CC       its C-terminus domain. Interacts with the tail assembly proteins.
CC       {ECO:0000255|HAMAP-Rule:MF_04138}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000255|HAMAP-Rule:MF_04138}.
CC   -!- SIMILARITY: Belongs to the Lambdavirus tape measure protein family.
CC       {ECO:0000255|HAMAP-Rule:MF_04138}.
