RyeB RNA
Non-coding RNA
From Wikipedia, the free encyclopedia
The SdsR/RyeB RNA is a non-coding RNA that was identified in a large scale screen of E. coli.[1] The exact 5′ and 3′ ends of this RNA are uncertain. This RNA overlaps the SraC/RyeA RNA on the opposite strand suggesting that the two may act in a concerted manner. It is transcribed by general stress factor σs and is most highly expressed in stationary phase. SdsR/RyeB RNA interacts with Hfq.

The homologous sRNA in S. enterica was shown to regulate synthesis of major porin OmpD.[2] A study using Salmonella identified 20 targets of this sRNA including transcriptional regulator, CRP, global DNA-binding factors, StpA and HupB, the antibiotic transporter protein, TolC, and the RtsA/B two-component system (TCS), and validated their post-transcriptional control by SdsR/RyeB RNA.[3]
