- RNAIII
RNAIII is a
non-coding RNA which is known to regulate the expression of many "Staphylococcus aureus " genes encoding exoproteins and cell wall associated proteins. In "S. aureus", RNAIII acts as the effector of the agrquorum sensing system and is transcribed from the P3 operon. The RNAIII transcript also contains the 26 amino acid delta-haemolysin gene (hld).

It has been suggested that RNAIII binds to the rot mRNA in an antisense fashion occluding theShine-Dalgarno sequence cite journal | author = Geisinger E, Adhikari RP, Jin R, Ross HF, Novick RP | title = Inhibition of rot translation by RNAIII, a key feature of agr function | journal = Mol.
