Webb8 apr. 2024 · Riboswitches are cis-acting gene-regulatory RNA elements that can function at the level of transcription, translation and RNA cleavage1, 2, 3. The commonly accepted molecular mechanism for riboswitch function proposes a ligand-dependent conformational switch between two mutually exclusive states4.
Webb1 juni 2011 · Riboswitches are genetic elements located in non‐coding regions of some messenger RNAs (mRNAs) that are present in all three domains of life. The binding of ligands to riboswitches induces conformational changes in the mRNA molecule, resulting in modulation of gene transcription, or RNA splicing, translation or stability.
