CtRNA

In molecular biology ctRNA is a plasmid encoded noncoding RNA that binds to the mRNA of and causes translational inhibition.
ctRNA is encoded by plasmids and functions in rolling circle replication to maintain a low copy number. In Corynebacterium glutamicum, it achieves this by antisense pairing with the mRNA of, a replication initiation protein.
In Enterococcus faecium the plasmid pJB01 contains three open reading frames, copA,, and. The pJB01 ctRNA is coded on the opposite strand from the / intergenic region and partially overlaps an atypical ribosome binding site for.
