CC -!- FUNCTION: This protein is one of the two subunits of integration host
CC factor, a specific DNA-binding protein that functions in genetic
CC recombination as well as in transcriptional and translational control.
CC {ECO:0000256|HAMAP-Rule:MF_00380, ECO:0000256|RuleBase:RU004485}.
CC -!- SUBUNIT: Heterodimer of an alpha and a beta chain. {ECO:0000256|HAMAP-
CC Rule:MF_00380, ECO:0000256|RuleBase:RU004485}.
CC -!- SIMILARITY: Belongs to the bacterial histone-like protein family.
