CC   -!- FUNCTION: Member of the two-component regulatory system LytR/LytS that
CC       regulates genes involved in autolysis, programmed cell death, biofilm
CC       formation and cell wall metabolism. Participates also in sensing and
CC       responding to host defense cationic antimicrobial peptides (HDPs). Upon
CC       phosphorylation by LytS, functions as a transcription regulator by
CC       direct binding to promoter regions of target genes including lrgA and
CC       lrgB, to positively regulate their expression.
CC       {ECO:0000250|UniProtKB:P60611}.
CC   -!- SUBUNIT: Homodimer; when phosphorylated.
CC       {ECO:0000250|UniProtKB:P60609}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- PTM: Phosphorylated and dephosphorylated by LytS.
CC       {ECO:0000250|UniProtKB:P60609}.
