Can nonfunctional riboswitches be repaired
Riboswitches are often conceptually divided into two parts: an aptamer and an expression platform. The aptamer directly binds the small molecule, and the expression platform undergoes structural changes in response to the changes in the aptamer. The expression platform is what regulates gene expression. Expression platforms typically turn off gene expression in response to the small molecule, but s… WebThe Mn2+ Riboswitch. The Mn2+ sensing yybP-ykoY riboswitch is one of the most commonly found riboswitches in bacteria, and it is primarily responsible for coordinating the response of Mn2+ homeostasis genes. A recent study by the Walter lab elucidated that Mn2+ binding induces small local RNA structural changes which cascade through the ...

WebOct 1, 2024 · Riboswitches are predominantly located in the 5′untranslated region (5′-UTR) of mRNA; however, they can be present in the 3′-UTR in some eukaryotic mRNA. Similar to regulatory proteins, riboswitches act as molecular sensors able to regulate the level of gene expression through the conformational changes caused by binding to a specific ligand. WebMay 31, 2024 · TPP riboswitches are rare in yeasts. However, we find that TPP riboswitches are conserved in an ancient thiamin transporter, found in filamentous fungi, yeasts and other related organisms. ... RFP_Lin-1_R.
