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:0000255|HAMAP-Rule:MF_00381}.
CC   -!- SUBUNIT: Heterodimer of an alpha and a beta chain. {ECO:0000255|HAMAP-
CC       Rule:MF_00381}.
CC   -!- SIMILARITY: Belongs to the bacterial histone-like protein family.
CC       {ECO:0000255|HAMAP-Rule:MF_00381}.
