CC   -!- FUNCTION: Structural component of the short non-contractile tail. The
CC       tail complex is involved in viral genome delivery. Forms the 12-fold
CC       symmetric toroidal domain immediately below the connector protein gp8.
CC       Once the tail tubular structure is formed, the interface between gp11
CC       and gp12 generates the proper environment to interact with the six
CC       fibers, each made of gp17 trimers. {ECO:0000269|PubMed:23884409}.
CC   -!- SUBUNIT: Interacts with head-to-tail connector protein gp8, the tail
CC       component gp12, and the fiber protein gp17.
CC       {ECO:0000269|PubMed:23884409}.
CC   -!- SUBCELLULAR LOCATION: Virion.
