Conservation and evolution of the programmed ribosomal frameshift in prfB across the bacterial domain | mBio
Translation termination is catalyzed by one of two release factors in bacteria, RF1 or RF2. It has been known for decades that RF2 levels in Escherichia coli are regulated by a programmed ribosomal frameshift within the prfB gene that encodes RF2. We ...

Quality over quantity: Small RNA pauses translation elongation to lift protein activity
Small noncoding RNAs typically regulate the translation initiation of target mRNAs
and thereby protein production. In this issue of Molecular Cell, Thongdee et al. discovered
a novel regulatory mechan...
