In several groups of bacterial plasmids, antisense RNAs regulate copy number through inhibition of replication initiator protein synthesis. These RNAs are characterised by a long hairpin structure interrupted by several unpaired nucleotides or bulged loops. In plasmid R1, the inhibitory complex between the antisense RNA (CopA) and its target mRNA (CopT) is characterised by a four-way junction structure and a side-by-side helical alignment.[1][2][3]
