CC -!- FUNCTION: Plays an essential role most probably in virion tail
CC assembly. May form a scaffold around which gp11 and gp12 polymerize.
CC Gets ejected from the infecting particle into the bacterial cell.
CC {ECO:0000269|PubMed:16054667}.
CC -!- SUBCELLULAR LOCATION: Virion {ECO:0000269|PubMed:16054667}.
CC Note=Component of the tail.
CC -!- SIMILARITY: Belongs to the T7likevirus protein 7.3 family.
CC {ECO:0000305}.
