CC   -!- FUNCTION: A key translational regulator that binds mRNA to regulate
CC       translation initiation and/or mRNA stability. Mediates global changes
CC       in gene expression, shifting from rapid growth to stress survival by
CC       linking envelope stress, the stringent response and the catabolite
CC       repression systems. Usually binds in the 5'-UTR; binding at or near the
CC       Shine-Dalgarno sequence prevents ribosome-binding, repressing
CC       translation, binding elsewhere in the 5'-UTR can activate translation
CC       and/or stabilize the mRNA. Its function is antagonized by small RNA(s).
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}.
