CC   -!- FUNCTION: May initiate with G7P the virion concomitant assembly-budding
CC       process, by interacting with the packaging signal of the viral genome.
CC       The assembly-budding takes place at the host inner membrane. In turn,
CC       G7P and G9P are present at the end of the filamentous virion that
CC       emerges first from the bacterial host (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000305}. Host membrane
CC       {ECO:0000305}; Single-pass membrane protein {ECO:0000305}. Note=Prior
CC       to assembly, is found associated with the bacterial host inner
CC       membrane. There are about five copies of this protein per mature phage
CC       that are located on the tail side of the filamentous virion with G7P
CC       (By similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the inovirus G9P protein family. {ECO:0000305}.
