RsaOG (an acronym for RNA S. aureus Orsay G)[2] is a non-coding RNA that was discovered in the pathogenic bacteria Staphylococcus aureus N315 using a large-scale computational screening based on phylogenetic profiling.[3] It was first identified, but not named, in 2005.[4] RsaOG has since been identified in other strains of Staphylococcus aureus under the name of RsaI,[5] it has also been discovered in other members of the Staphylococcus genus (such as Staphylococcus carnosus) but in no other bacteria.[2]

The RsaOG gene is conserved in all Staphylococcaceae sequenced genomes, its secondary structure contains two highly conserved unpaired sequences which have the ability to form a pseudoknot.[2] Northern blot experiments show that RsaOG is expressed in several S. aureus strains.[3][5] Mapping of RsaOG ends indicates a size of 146 nucleotides in S. aureus.[5] RsaOG ncRNA is thought to have trans-acting regulatory functions, possibly on fine-tuning toxin production or aiding with invasion.[2]
