Cytosolic translation
WebFeb 20, 2024 · Cytosolic mRNA translation is subject to global and mRNA-specific controls. Phosphorylation of the translation initiation factor eIF2α anchors a reversible regulatory switch that represses cytosolic translation globally. The stress-responsive GCN2 kinase is the only known kinase for eIF2α serine 56 in Arabidopsis ( Arabidopsis … WebUnexpectedly, the mitochondrial requirement was linked to mitochondrial translation, inhibition of which impaired CTL killing. Impaired mitochondrial translation triggered attenuated cytosolic translation, precluded …

WebFeb 1, 2024 · Here we report: 1) a method for visualizing protein synthesis in human mitochondria at super resolution; 2) that synthesis is enriched at cristae membranes, in preference to the IBM; and 3) that sites of translation are spatially separated from RNA granules where RNA processing, maturation, and mitoribosomal assembly occur. Abstract WebMar 3, 2024 · The repression of cytosolic translation and extension of lifespan from mrps-5 RNAi were dependent on atf-5/ATF4 and independent from metabolic phenotypes. We found the translational balance to be conserved in mammalian cells upon inhibiting mitochondrial translation pharmacologically with doxycycline. Lastly, extending this in …
WebJan 18, 2024 · Cytosolic translation can be regulated by viral infection in animal cells (Sonenberg and Hinnebusch, 2009). Here, we found that cytosolic translation might also be modulated by pathogen infection in plants because M. oryzae–infected plants showed hyperoxidation of ribosomal proteins. To test this hypothesis, we performed ribosomal … WebJan 26, 2024 · In gregarious locusts, ten genes involved in the cytosolic ribosome pathway exhibited increased translational efficiency (TE). In solitary locusts, five genes from the mitochondrial ribosome pathway displayed increased TE.
WebMay 11, 2016 · Instead, mitochondrial and cytosolic translation are rapidly, dynamically and synchronously regulated. Furthermore, cytosolic translation processes control mitochondrial translation... WebThe regulation of cytosolic mRNA translation is crucial for rapid adaptation to environmental stress conditions. General control nonderepressible 2 (GCN2) is a Ser-Thr kinase found in all eukaryotic organisms that phosphorylate eukaryotic translation initiation factor 2 (eIF2) under cold stress, which inhibits the initiation of protein ...
WebJan 26, 2024 · The isolation of translation-competent mitochondria through sequential centrifugation provides an alternative option to the compound-mediated shutoff of cytosolic translation for radiolabeling of the proteins synthesized in the organelle (24– 27).For example, this method can be applied for tissues that are difficult to pretreat with …
WebJul 13, 2024 · Eukaryotic cells contain semi-autonomous organelles that have lost most of their coding capacity for essential proteins to the nucleus. Therefore, their functioning depends on the cytosolic translation products of nuclear-encoded genes that must be imported by a specialized protein import machinery.
