UniProtKB description: Down-regulates hemolysin (hly) expression in complex with H-NS (PubMed:10778755, PubMed:11790731, PubMed:1956303, PubMed:21600204). Stimulates transposition events in vivo (PubMed:8145648). Modifies the set of genes regulated by H-NS; Hha and Cnu (YdgT) increase the number of genes DNA bound by H-NS/StpA and may also modulate the oligomerization of the H-NS/StpA-complex (PubMed:23543115). Binds DNA and influences DNA topology in response to environmental stimuli; does not however interact with DNA in the absence of H-NS (PubMed:23543115). Involved in persister cell formation, acting downstream of mRNA interferase (toxin) MqsR (PubMed:19909729). Decreases biofilm formation by repressing the transcription of fimbrial genes fimA and ihfA, and by repressing the transcription of tRNAs corresponding to rare codons, which are abundant in type 1 fimbrial genes (PubMed:18545668).
