CC   -!- FUNCTION: Copper-sensitive repressor that has a key role in copper
CC       homeostasis. It is part of the cso operon involved in the cellular
CC       response to increasing concentrations of copper inside the bacterium,
CC       which can be highly toxic. In the presence of copper, CsoR fully
CC       dissociates from the promoter in the cso operon, leading to the
CC       transcription of its genes (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the CsoR family. {ECO:0000305}.
