title: U-turns and regulatory RNAs.
abstract: Conventional antisense RNAs, such as those controlling plasmid replication and maintenance, inhibit the function of their target RNAs rapidly and efficiently. Novel findings show that a common U-turn loop structure mediates fast RNA pairing in the majority of these RNA controlled systems. Usually, an antisense RNA regulates a single, cognate target RNA only. Recent reports, however, show that antisense RNAs can act as promiscuous regulators that control multiple genes in concert to integrate complex physiological responses in Escherichia coli.
