It is used as an autoregulatory mechanism to control the concentration of the ribosomal protein eL15, which is used in archaea and eukaryotes.

Known Examples were predicted in Euryarchaeota with bioinformatic approaches.

[1] The structure is located in the 5′ untranslated regions of mRNAs encoding ribosomal proteins eL15 (rpl15e).

[1] Similarities between the eL15 ribosomal protein and the rRNA site to which this protein binds were detected.
