RncO is a bacterial non-coding RNA regulatory element found in the rnc leader sequence. The rnc operon is negatively auto-regulated by transcript stability. rnc, the first gene in the operon codes for RNase III which cleaves the long rncO stem II leading to transcript degradation and a reduction in translation.[1] Matsunaga et al. showed that RNase III cleavage can initiate rnc transcript decay independently of rnc gene translation.[2] Further work has established that rncO structure and function is conserved in Salmonella typhimurium.[3]
