CC -!- FUNCTION: Plays essential roles both in the entry of the viral genome
CC into the bacterial host and in budding process. The formation of the
CC G3P-G6P complex termed adsorption complex is essential for correct
CC termination of filamentous phage assembly.
CC -!- SUBUNIT: Interacts with G3P; this interaction is required for proper
CC integration of G3P and G6P into the virion.
CC {ECO:0000269|PubMed:7746960}.
CC -!- SUBCELLULAR LOCATION: Virion {ECO:0000305}. Host membrane
CC {ECO:0000305}; Multi-pass membrane protein {ECO:0000305}. Note=Prior to
CC assembly, G6P is found associated with the bacterial host inner
CC membrane. There are about five copies of G6P in the mature virion. They
CC are located together with G3P at the head side of the filamentous
CC virion.
CC -!- SIMILARITY: Belongs to the inovirus G6P protein family. {ECO:0000305}.
