The majority of the DNA sequence in our genome is noncoding and not intended for synthesizing proteins. Nonetheless, genome-wide mapping of ribosome footprints has revealed widespread translation in annotated noncoding sequences, including long noncoding RNAs (lncRNAs), untranslated regions (UTRs), and introns of mRNAs. How cells suppress the translation of potentially toxic proteins from various noncoding sequences remains poorly understood. This review summarizes mechanisms for the mitigation of noncoding translation, including the BCL2-associated athanogene 6 (BAG6)-mediated proteasomal degradation pathway, which has emerged as a unifying mechanism to suppress the translation of diverse noncoding sequences in metazoan cells.
期刊介绍：
Trends in Cell Biology stands as a prominent review journal in molecular and cell biology. Monthly review articles track the current breadth and depth of research in cell biology, reporting on emerging developments and integrating various methods, disciplines, and principles. Beyond Reviews, the journal features Opinion articles that follow trends, offer innovative ideas, and provide insights into the implications of new developments, suggesting future directions. All articles are commissioned from leading scientists and undergo rigorous peer-review to ensure balance and accuracy.
