CC   -!- FUNCTION: Binds to the sigma-S subunit of RNA polymerase, activating
CC       expression of sigma-S-regulated genes, such as the csgBAC operon
CC       encoding the subunits of curli proteins, and BcsA, involved in
CC       cellulose biosynthesis. {ECO:0000269|PubMed:16707690}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- INDUCTION: Induced at late exponential and stationary phases, and at
CC       low temperatures. {ECO:0000269|PubMed:16707690}.
CC   -!- SIMILARITY: Belongs to the Crl family. {ECO:0000305}.
