CC   -!- FUNCTION: Involved in the regulation of virulence genes. Acts as a
CC       repressor of the agr locus and consequently targets genes regulated by
CC       the agr system such as sspA, hla and hlb. Binds directly to the agr
CC       promoter region (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the SarA family. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=CAI80305.1; Type=Erroneous initiation; Evidence={ECO:0000305};
