The CpxQ sRNA is derived from the last 58 nt of the 67 nt cpxP 3' UTR and was originally identified as STnc870 by RNA-Seq of Hfq-bound sRNAs in Salmonella typhimurium (Chao, 2012). The 5' end of the Salmonella typhimurium CpxQ sRNA is generated by RNase E cleavage and the 5' end was confirmed by primer extension; the 5' and 3' ends of E. coli CpxQ are inferred from Salmonella typhimurium CpxQ (Chao, 2016). The CpxQ sRNA was shown to down-regulate CpxP and Skp in E. coli (Grabowicz, 2017).
