In fruit flies, maternally deposited RNA-binding proteins are removed during the maternal-to-zygotic transition via a mechanism of translational upregulation of Kondo, the key E2 enzyme, at egg activation.
Operonic mRNAs in bacteria are comprised of ORF (open reading frame)-wide units of secondary structure, which are intrinsically distinct between adjacent ORFs and encode a rough blueprint for ORF-specific translation efficiency.
ME31B is a general repressor of gene expression in the Drosophila early embryo, repressing translation before the maternal-to-zygotic transition and stimulating mRNA decay after activation of the zygotic genome.
Non-invasive mRNA stability measurements reveal that transcript lifetime is governed by a competition with translation initiation on a transcriptome-wide level.
Asc1/RACK1 promotes the translation of mRNAs associated with the translational closed loop complex, which have short open reading frames and encode proteins required for core metabolic processes.
Experimental evolution and systematic sequence analysis of transfer RNA genes reveal that anticodon mutations provide adaptive plasticity to the translation machinery.
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.
Profiling of mRNA poly(A)-tail lengths and translational efficiencies provides new insights into posttranscriptional gene regulation in early Drosophila development.
