[[https://www.uniprot.org/uniprot/HNS_ECOLI HNS_ECOLI]] A DNA-binding protein implicated in transcriptional repression (silencing) as well as in bacterial chromosome organization. H-NS binds tightly to AT-rich dsDNA, increases its thermal stability and inhibits transcription. Also binds to ssDNA and RNA but with a much lower affinity. H-NS has possible histone-like function. May be a global transcriptional regulator through its ability to bind to curved DNA sequences, which are found in regions upstream of a certain subset of promoters. Plays a role in the thermal control of pili and adhesive curli fimbriae production, by inducing transcription of csgD. Represses the CRISPR-cas promoters, permits only weak transcription of the crRNA precursor; its role is antagonized by LeuO. Subject to transcriptional auto-repression. Binds preferentially to the upstream region of its own gene recognizing two segments of DNA on both sides of a bend centered around -150.<ref>PMID:7934818</ref> <ref>PMID:11031114</ref> <ref>PMID:17010156</ref> <ref>PMID:20659289</ref>
