This gene lies between yegQ and orgK in E. coli.

This small RNA was shown to be bound by the Hfq protein.

It has been shown that the 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] A comparative genomics approach was able to detect and verify the additional targets ptsI, sdhA and yobF.
