CONTROL OF COLE1 PLASMID REPLICATION BY ANTISENSE RNA

One of the two major classes of regulatory strategies that control plasmid copy number involves recognition via base pairing between two plasmid-encoded complementary RNAs. The detailed analysis of this control circuitry has revealed some features of regulatory mechanisms based on RNA-RNA interaction that distinguish them from those based on protein-nucleic acid interaction. These features provide a framework with which to understand other regulatory mechanisms based on RNA-RNA interaction, and will aid in the design of efficient artificial antisense RNA systems.
