Trm9-Catalyzed tRNA Modifications Regulate Global Protein Expression by Codon-Biased Translation.
Post-transcriptional modifications of transfer RNAs (tRNAs) have long been recognized to play crucial roles in regulating the rate and fidelity of translation. However, the extent to which they determine global protein production remains poorly understood. Here we use quantitative proteomics to show a direct link between wobble uridine 5-methoxycarbonylmethyl (mcm5) and 5-methoxy-carbonyl-methy...
متن کاملChromatin modifications and the DNA damage response to ionizing radiation
In order to survive, cells have evolved highly effective repair mechanisms to deal with the potentially lethal DNA damage produced by exposure to endogenous as well as exogenous agents. Ionizing radiation exposure induces highly lethal DNA damage, especially DNA double-strand breaks (DSBs), that is sensed by the cellular machinery and then subsequently repaired by either of two different DSB re...
متن کاملDynamics of plant histone modifications in response to DNA damage.
DNA damage detection and repair take place in the context of chromatin, and histone proteins play important roles in these events. Post-translational modifications of histone proteins are involved in repair and DNA damage signalling processes in response to genotoxic stresses. In particular, acetylation of histones H3 and H4 plays an important role in the mammalian and yeast DNA damage response...
متن کاملtRNA modifications regulate translation during cellular stress.
The regulation of gene expression in response to stress is an essential cellular protection mechanism. Recent advances in tRNA modification analysis and genome-based codon bias analytics have facilitated studies that lead to a novel model for translational control, with translation elongation dynamically regulated during stress responses. Stress-induced increases in specific anticodon wobble ba...
متن کاملSpatiotemporal regulation of posttranslational modifications in the DNA damage response.
A timely and accurate cellular response to DNA damage requires tight regulation of the action of DNA damage response (DDR) proteins at lesions. A multitude of posttranslational modifications (PTMs) of chromatin and chromatin-associated proteins coordinates the recruitment of critical proteins that dictate the appropriate DNA repair pathway and enable the actual repair of lesions. Phosphorylatio...
