CC -!- FUNCTION: Global regulator with both positive and negative effects that
CC controls expression of several virulence factors and biofilm formation
CC process in a cell density-dependent manner. In a strain-dependent
CC manner plays a role in multidrug resistance mechanism. Is required for
CC transcription of primary transcripts RNAII and RNAIII generated by agr
CC (virulence accessory gene regulator) locus. Acts as a transcriptional
CC activator of the genes encoding, among others, for fibronectin binding
CC proteins (fnbA and fnbB), hemolysins (hla, hld, hlgB and hlgC), serine
CC proteases (splA, splB, splD and splF) and of the bap gene, which is
CC essential for biofilm development in some strains. Negatively regulates
CC the expression of the genes for protein A (spa), lipase (lip),
CC thermonuclease (nuc), immunodominant staphylococcal antigen B (isaB),
CC staphylococcal serine and cysteine proteases (sspA and sspB),
CC staphostatin B (sspC), metalloprotease aureolysin (aur) and collagen
CC adhesin (cna). Probably activates the development of biofilm by both
CC enhancing the ica operon transcription and suppressing the
CC transcription of either a protein involved in the turnover of PIA/PNAG
CC or a repressor of its synthesis, whose expression would be sigma-B-
CC dependent. {ECO:0000269|PubMed:15321676, ECO:0000269|PubMed:16077127}.
CC -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC -!- INDUCTION: Expressed at the exponential growth phase and maximally
CC induced during the transition from late exponential phase to stationary
CC phase. Repressed by SarR and activated by two-component regulatory
CC system ArlS/ArlR. Activated by SigB in strains harboring an intact sigB
CC operon (rsbU, rsbV, rsbW, and sigB). Transcription is also attenuated
CC by MsrR.
CC -!- SIMILARITY: Belongs to the SarA family. {ECO:0000305}.
