CC   -!- FUNCTION: Signal transduction protein, which is a major regulator of
CC       staphylococcal pathogenesis. Phosphorylated TRAP leads to the
CC       activation of agr system and consequent RNAIII synthesis resulting in
CC       the expression of several virulence factors. Up-regulates the
CC       expression of most toxins and genes known to be necessary for biofilm
CC       formation (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Membrane. Note=Membrane-associated.
CC       {ECO:0000250}.
CC   -!- PTM: Each of the three conserved histidine residues contributes to TRAP
CC       phosphorylation. Phosphorylation is essential for TRAP activity (By
CC       similarity). {ECO:0000250}.
CC   -!- PTM: Phosphorylation of TRAP is activated by RAP and necessary for the
CC       induction of RNAIII gene expression but not for ongoing transcription.
CC       TRAP is dephosphorylated from the mid-exponential phase of growth,
CC       which is when agr is activated and AIP is produced. RIP acts by
CC       inhibiting TRAP phosphorylation (By similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the TRAP family. {ECO:0000305}.
