Chemical modifications near the tRNA anticodon and specific mRNA–tRNA pairs combine to control the ribosomal three-nucleotide mRNA reading frame, essential for the sequential addition of amino acids into polypeptide chains.
In mitotically aging yeast cells, the cytosol acidifies, the distances between the organellar membranes decrease dramatically, but crowding on the scale of the average size protein is relatively stable.
Context-dependent optimization of Gli-binding site occupancy, in the presence of Hand2, is critical for modulating tissue-specific transcriptional output within tissues that lack an obvious Hedgehog morphogen gradient.
Imaging of energy status and autophagy during neuronal migration revealed that ATP/ADP levels dynamically change during the migratory and stationary phases and that ATP reduction induces autophagy to maintain migration.
The cancer testis antigen COX6B2 enhances cytochrome c oxidase activity thereby promoting proliferation and survival in cancer cells and represents a therapeutic target for inhibiting oxidative phosphorylation selectively in tumors.
