CC   -!- FUNCTION: May confer an overall protective ability to the host cell by
CC       triggering a growth arrest and avoiding lethal host gene expression.
CC       Additionally, may confer symbiotic protection to the lysogenic host
CC       against secondary infection. {ECO:0000269|PubMed:11790759,
