CC   -!- FUNCTION: Binds to the sigma-S subunit of RNA polymerase, activating
CC       expression of sigma-S-regulated genes. Stimulates RNA polymerase
CC       holoenzyme formation and may bind to several other sigma factors, such
CC       as sigma-70 and sigma-32. {ECO:0000255|HAMAP-Rule:MF_01178}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01178}.
CC   -!- SIMILARITY: Belongs to the Crl family. {ECO:0000255|HAMAP-
CC       Rule:MF_01178}.
