Without ribosome recycling factor, ribosomes in Escherichia coli accumulate in 3'-UTRs and queue upstream of stop codons, but no effects were observed on the translational coupling of neighboring genes.
For poly(A)-tail length to influence mRNA translational efficiency, poly(A)-binding protein (PABPC) must be limiting, mRNAs lacking PABPC must be stable, and translation initiation must be sensitive to PABPC levels.
The deletion of Ddx6 results in the translational upregulation, but not transcript stabilization, of microRNA targets in embryonic stem cells while largely phenocopying the overall impact of global microRNA loss.
Cryo-EM structures of the 30S*RNAP complex visualize co-localization of the transcription and translation machineries and provide insights into the transcription-translation synchrony, which coordinates gene expression in bacteria.
A comprehensive mapping of the proteome and transcriptome during the complete replicative lifespan of budding yeast predicted an increased abundance of the protein biogenesis machinery is most causal for aging.
