RNA sensors and riboswitches: self-regulating messages.
Recent years have seen the discovery of myriad new regulatory and catalytic functions for RNA. A series of new studies have now demonstrated that certain RNA sequences can directly sense ambient temperature or any of a variety of small molecule metabolites. Remarkably, these sensors allow associated mRNAs to regulate their own transcription or translation accordingly, without the need for regulatory proteins.
