CC   -!- FUNCTION: A translational regulator that binds mRNA to regulate
CC       translation initiation and/or mRNA stability. Usually binds in the 5'-
CC       UTR at or near the Shine-Dalgarno sequence preventing ribosome-binding,
CC       thus repressing translation. Its main target seems to be the major
CC       flagellin gene, while its function is anatagonized by FliW.
CC       {ECO:0000255|HAMAP-Rule:MF_00167}.
CC   -!- SUBUNIT: Homodimer; the beta-strands of each monomer intercalate to
CC       form a hydrophobic core, while the alpha-helices form wings that extend
CC       away from the core. {ECO:0000255|HAMAP-Rule:MF_00167}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00167}.
CC   -!- SIMILARITY: Belongs to the CsrA/RsmA family. {ECO:0000255|HAMAP-
CC       Rule:MF_00167}.
