Riboswitch regulation
WebbRiboswitch. A riboswitch is a cis-regulatory RNA element that regulates expression of a downstream or upstream gene in response to a specific ligand molecule (Roth & … WebbCis-regulatory elements ( CREs) or Cis-regulatory modules ( CRMs) are regions of non-coding DNA which regulate the transcription of neighboring genes. CREs are vital components of genetic regulatory networks, which in turn control morphogenesis, the development of anatomy, and other aspects of embryonic development, studied in …

Webb12 dec. 2024 · Riboswitches are natural biosensors that can regulate gene expression by sensing small molecules. Knowledge of the structural dynamics of riboswitches is crucial to elucidate their regulatory mechanism and develop RNA biosensors. In this work, we incorporated the fluorophore, Cy3, and its quencher, TQ3, into a full-length adenine … WebbRiboswitches are unique among cellular regulators in that metabolite detection is strictly performed using RNA interactions with the sensed metabolite and in which no …
