WebApr 13, 2024 · Riboswitches are found in the 5′ untranslated regions (UTRs) of many mRNAs and contain a ligand-binding aptamer whose conformation rearranges upon ligand binding, thereby modulating downstream gene expression by controlling transcription termination or translation initiation ( 22 ). Web(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 [205] and regulation of mRNA stability [56, 57, 206].

WebFeb 2, 2024 · Bacteria absorb cobalt and nickel from their environment using ion transport proteins that are embedded in their cellular membrane. Interestingly, the mRNAs that encode for these transport proteins contain riboswitches. When nickel and cobalt are present in the cell, they will bind to these riboswitches, changing their shape. WebSep 15, 2024 · The riboswitch is a part of an mRNA molecule that can bind and target small target molecules. An mRNA molecule may contain a riboswitch that directly regulates its own expression.

WebHow do riboswitches work? In molecular biology, a riboswitch is a regulatory segment of a messenger RNA molecule that binds a small molecule, resulting in a change in production of the proteins encoded by the mRNA.
