CC   -!- FUNCTION: Binds to H-NS and modified the range of genes it silences; H-
CC       NS alonge silences core gene while the H-NS-Hha complex (and presumably
CC       also H-NS-YdgT) silences genes acquired by horizontal gene transfer.
CC       Plays a role silencing virulence factors in the absence of factors that
CC       induce pathogenicity (By similarity). The complex formed with H-NS
CC       binds to the specific 26-bp cnb site in the origin of replication oriC
CC       (By similarity). {ECO:0000250|UniProtKB:A0A0H3NGF1,
CC       ECO:0000250|UniProtKB:P64467}.
CC   -!- SUBUNIT: Forms complexes with both H-NS and StpA.
CC       {ECO:0000250|UniProtKB:Q7CQK5}.
CC   -!- SIMILARITY: Belongs to the Hha/YmoA/Cnu family. {ECO:0000305}.
