Mechanism of read-through enhancement by aminoglycosides and mefloquine.
Proc.Natl.Acad.Sci.USA 122 e2420261122 e2420261122 (2025)
PMID: 40273100 DOI: 10.1073/pnas.2420261122

Abstact

Nonsense mutations are associated with numerous and diverse pathologies, yet effective treatment strategies remain elusive. A promising approach to combat these conditions involves the use of aminoglycosides, particularly in combination with stop-codon read-through enhancers, for developing drugs that can rescue the production of full-length proteins. Using X-ray crystallography and single-particle cryo-EM, we obtained structures of the eukaryotic ribosome in complexes with several aminoglycosides (geneticin G418, paromomycin, and hygromycin B) and the antimalarial drug mefloquine (MFQ), which has also been identified as a read-through enhancer. Our study reveals a binding site of MFQ, which holds significant promise for the development of therapies targeting premature termination codon-related genetic and oncological diseases. The results underscore the crucial role of the bridge B7b/c in mediating the effects of MFQ on subunit rotation dynamics. Through a comprehensive analysis of the interactions between the drugs and the eukaryotic ribosome, we propose a unifying hypothesis for read-through enhancement by small molecules, highlighting the role of decoding center rearrangements and intersubunit rotation dynamics.
