UniProtKB description: One of the 2 subunits of integration host factor (IHF), a specific DNA-binding protein that functions in genetic recombination as well as in transcriptional and translational control. Binds to hundreds of transcriptionally inactive, AT-rich DNA sites, approximately half its binding sites are in non-coding DNA, which only accounts for about 10% of the genome (PubMed:16963779). IHF in combination with the datA locus promotes ATP hydrolysis of ATP-DnaA, called DDAH (datA-dependent DnaA-ATP hydrolysis) (PubMed:23277577). IHF binds oriC as replication initiates, dissociates within minutes and slowly reassociates during the cell cyle; IHF binding to datA is low before initiation, rises after initiation and dissociates during the cell cycle, allowing IHF to coordinate replication initiation (PubMed:23277577).
