CC   -!- FUNCTION: Plays a role in tail tip complex assembly. The tail tip
CC       complex is assembled successively with three tail tip proteins J, one
CC       tail tip protein I, one tail tip protein L and one tail tip protein K.
CC       The tail tip complex interacts with tail measure protein to initiate
CC       tail tube assembly. The formation of the tail tip complex is completed
CC       by the addition of tail tip protein M, which is followed by tail tube
CC       polymerization. May be excluded form tail tip during maturation and
CC       would be absent from virions. {ECO:0000250|UniProtKB:P03730}.
CC   -!- SUBCELLULAR LOCATION: Host cytoplasm {ECO:0000250|UniProtKB:P03730}.
CC   -!- SIMILARITY: Belongs to the lambda-like tail tip protein I family.
CC       {ECO:0000305}.
