SymR RNA is a non-coding RNA which forms a type I toxin-antitoxin system along with the protein SymE. SymR was originally labelled RyjC and is a 77nt RNA with a σ70 promoter. RyjC was found to overlap the yjiW open reading frame on the opposite strand by 6nt, and was characterised as an antisense RNA which bound the 5' untranslated region of yjiW. Further study led to the renaming of both yjiW and RyjC to SymE (SOS-induced yjiW gene with similarity to MazE) and SymR (symbiotic RNA) respectively.
