"WebbRiboswitches are regions of mRNAs that contain specific evolutionarily conserved ligand-binding (sensor) domains along with a variable sequence, termed the expression platform, that enables regulation of the downstream coding sequences. The term “riboswitch” reflects the ability of these noncoding RNAs to function as genetic switches. " - Riboswitch breaker

Webb19 jan. 2024 · A riboswitch is a molecular mechanism, found in the three kingdoms of life, in which the RNA structure is modified by the binding of a metabolite. It can regulate multiple gene expression mechanisms, such as transcription, translation initiation, and mRNA splicing and processing. Webb1 feb. 2024 · (A) Riboswitches typically use partly overlapping aptamer and expression platform domains to regulate transcription termination (left), translation initiation (center), or alternative splicing (right). Rarer mechanisms include transcriptional interference [ 202] and the regulation of mRNA stability [ 56, 57, 203 ].
