The CyaR RNA (formerly known as RyeE RNA) non-coding RNA was identified in a large scale screen of E. coli and was called candidate 14.[1] The exact 5' and 3' ends of this RNA are uncertain. This gene lies between yegQ and orgK in E. coli. This small RNA was shown to be bound by the Hfq protein. This RNA has been renamed as CyaR for (cyclic AMP-activated RNA). It has recently been shown that CyaR RNA acts as a repressor of the porin OmpX.[2] It has also been shown that cyaR expression is tightly controlled by the cyclic AMP receptor protein, CRP.[2]
