The CyaR RNA (formerly known as RyeE RNA) non-coding RNA was identified in a large scale screen of ''Escherichia coli'' and was called candidate 14. 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 been shown that the CyaR RNA acts as a repressor of the porin OmpX. It has also been shown that ''cyaR'' expression is tightly controlled by the cyclic AMP receptor protein, CRP.〔 A comparative genomics approach was able to detect and verify the additional targets ''ptsI'', ''sdhA'' and ''yobF''. ==See also== *RydB RNA *RyhB RNA *RyeB RNA 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「RyeE RNA」の詳細全文を読む スポンサード リンク
