Yfr1

Yfr1 is a Cyanobacterial functional RNA that was identified by a comparative genome based screen for RNAs in cyanobacteriacite journal |author=Axmann IM, Kensche P, Vogel J, Kohl S, Herzel H, Hess WR |title=Identification of cyanobacterial non-coding RNAs by comparative genome analysis. |journal=Genome Biol |volume=6 |issue=9 |pages=R73 |year=2005 |pmid=16168080] . Further analysis has shown that the RNA is well conserved and highly expressed in cyanobacteriacite journal |author=Voss B, Gierga G, Axmann IM, Hess WR |title=A motif-based search in bacterial genomes identifies the ortholog of the small RNA Yfr1 in all lineages of cyanobacteria. |journal=BMC Genomics |volume=8 |issue= |pages=375 |year=2007 |pmid=17941988] .
