These organelles have a bacterial origin and were acquired during an early endosymbiosis event2. Mitochondria possess specialized gene expression systems composed of various molecular machines including the mitochondrial ribosomes (mitoribosomes). Mitoribosomes are in charge of translating the few essential mRNAs still encoded by mitochondrial genomes3. While chloroplast ribosomes strongly resemble those of bacteria4,5, mitoribosomes have diverged significantly during evolution and present strikingly different structures across eukaryotic species6–10. In contrast to animals and trypanosomatides, plants mitoribosomes have unusually expanded ribosomal RNAs and conserved the short 5S rRNA, which is usually missing in mitoribosomes11. We have previously characterized the composition of the plant mitoribosome6 revealing a dozen plant-specific proteins, in addition to the common conserved mitoribosomal proteins. In spite of the tremendous recent advances in the field, plant mitoribosomes remained elusive to high-resolution structural investigations, and the plant-specific ribosomal features of unknown structures. -
Mitochondrial Misreading in Skeletal Muscle Accelerates Metabolic Aging and Confers Lipid Accumulation and Increased Inflammation

Here we used a combination of RNA-seq and metabolic profiling of ho- mozygous transgenic Mrps5V338Y/V338Y mice to analyze the changes associated with the V338Y mutation in postmitotic skeletal muscle. Metabolome analysis demonstrated enhanced levels of age-associated metabolites in the mutant V338Y animals accompanied by increased glycolysis, lipid desaturation and eicosanoid biosynthesis, and alterations of the pentose phosphate pathway. In addition, transcriptome signatures of aged V338Y mutant muscle pointed to elevated inflammation, likely reflecting the increased levels of bioactive lipids. Our findings indicate that mistranslation-mediated impairment of mitochondrial function affects specific bioenergetic processes in muscle in an age-dependent manner.

The Interactome of the Yeast Mitochondrial Ribosome
The interactome of the yeast mitochondrial ribosome Organization of mitochondrial post-transcriptional regulation, membrane protein insertion and quality control Braulio Vargas Möller-Hergt Academic dissertation for the Degree of Doctor of Philosophy in Biochemistry at Stockholm University to be publicly defended on Friday 19 October 2018 at 13.00 in Magnélisalen Kemiska övningslaboratoriet, Svante Arrhenius väg 16 B. Abstract The proteins found in mitochondria originate from two different genetic systems. Most mitochondrial proteins are synthesized in the cytosol and post-translationally imported into the organelle. However, a small subset of mitochondrial proteins is encoded in an organelle-resident genome. Mitochondria contain factors responsible for replication, transcription and, most important for this thesis, synthesis of the mitochondrially encoded proteins. In the course of evolution the mitochondria specific ribosomes were extensively remodeled. The reasons for many of these adaptations are currently not well understood. For example, the mitoribosome is less stable and abundant than its bacterial counterpart. Therefore, I contributed in the development of robust biochemical tools in order to isolate and analyze the intact yeast mitoribosome and interaction partners by mass spectrometry. The results revealed a higher order organization of mitochondrial gene expression in complexes that we termed MIOREX (mitochondrial organization of gene expression). Besides the mitoribosome, MIOREX complexes contain factors involved in all steps of gene expression. This study also established many new ribosomal interaction partners, among them some proteins that were previously completely uncharacterized. In order to study these proteins, I refined the mass spectrometry approach, allowing a subunit-specific assignment of ribosomal interaction partners. The Mrx15 protein was determined by this approach as an interactor of the large subunit. -

This involves final 18S rRNA processing and release of residual biogenesis factors, including the protein kinase RIOK1. To identify novel proteins promoting the final maturation of human 40S subunits, we characterized pre-ribosomal subunits trapped on RIOK1 by mass spectrometry, and identified the deubiquitinase USP16 among the captured factors. We demonstrate that USP16 constitutes a component of late cytoplasmic pre-40S subunits that promotes the removal of ubiquitin from an internal lysine of ribosomal protein *For correspondence: RPS27a/eS31.

Not all RPs are indispensable; in other words, the ribosome could be functional and could continue the translation of proteins instead of lacking in some of the RPs. However, the lack of many RPs could result in severe defects in the biogenesis of ribosomes, which could directly influence the overall translation processes and global expression of the proteins leading to the emergence of different diseases including cancer. While microRNAs (miRNAs) are small non-coding RNAs and one of the potent regulators of the post-transcriptional 0 gene expression, miRNAs regulate gene expression by targeting the 3 untranslated region and/or coding region of the messenger RNAs (mRNAs), and by interacting with the 50 untranslated region, Citation: Reza, A.M.M.T.; Yuan, Y.-G. -
Mitochondrial Translation and Its Impact on Protein Homeostasis And
Mitochondrial translation and its impact on protein homeostasis and aging Tamara Suhm Academic dissertation for the Degree of Doctor of Philosophy in Biochemistry at Stockholm University to be publicly defended on Friday 15 February 2019 at 09.00 in Magnélisalen, Kemiska övningslaboratoriet, Svante Arrhenius väg 16 B. Abstract Besides their famous role as powerhouse of the cell, mitochondria are also involved in many signaling processes and metabolism. Therefore, it is unsurprising that mitochondria are no isolated organelles but are in constant crosstalk with other parts of the cell. Due to the endosymbiotic origin of mitochondria, they still contain their own genome and gene expression machinery. The mitochondrial genome of yeast encodes eight proteins whereof seven are core subunits of the respiratory chain and ATP synthase. These subunits need to be assembled with subunits imported from the cytosol to ensure energy supply of the cell. Hence, coordination, timing and accuracy of mitochondrial gene expression is crucial for cellular energy production and homeostasis. Despite the central role of mitochondrial translation surprisingly little is known about the molecular mechanisms. In this work, I used baker’s yeast Saccharomyces cerevisiae to study different aspects of mitochondrial translation. Exploiting the unique possibility to make directed modifications in the mitochondrial genome of yeast, I established a mitochondrial encoded GFP reporter. This reporter allows monitoring of mitochondrial translation with different detection methods and enables more detailed studies focusing on timing and regulation of mitochondrial translation. Furthermore, employing insights gained from bacterial translation, we showed that mitochondrial translation efficiency directly impacts on protein homeostasis of the cytoplasm and lifespan by affecting stress handling. -

IDOL,1,3 DAN L. CRIMMINS,2 JACK H. LADENSON,2 PHILIP J. MASON,1,4 and MONICA BESSLER1,4 1Department of Internal Medicine, Division of Hematology, Washington University School of Medicine, St. Louis, Missouri 63110, USA 2Department of Pathology and Immunology, Division of Laboratory and Genomic Medicine, Washington University School of Medicine, St. Louis, Missouri 63110, USA ABSTRACT Production of ribosomes is a fundamental process that occurs in all dividing cells. It is a complex process consisting of the coordinated synthesis and assembly of four ribosomal RNAs (rRNA) with about 80 ribosomal proteins (r-proteins) involving more than 150 nonribosomal proteins and other factors. Diamond Blackfan anemia (DBA) is an inherited red cell aplasia caused by mutations in one of several r-proteins. How defects in r-proteins, essential for proliferation in all cells, lead to a human disease with a specific defect in red cell development is unknown. Here, we investigated the role of r-proteins in ribosome biogenesis in order to find out whether those mutated in DBA have any similarities. We depleted HeLa cells using siRNA for several individual r-proteins of the small (RPS6, RPS7, RPS15, RPS16, RPS17, RPS19, RPS24, RPS25, RPS28) or large subunit (RPL5, RPL7, RPL11, RPL14, RPL26, RPL35a) and studied the effect on rRNA processing and ribosome production. -

Analyzing Ribosome Remodeling in Health and Disease Aleksandra A
Analyzing ribosome remodeling in health and disease Aleksandra A. Petelski,1;2;3 & Nikolai Slavov1;2;3; 1Department of Bioengineering, Northeastern University, Boston, MA 02115, USA 2Barnett Institute, Northeastern University, Boston, MA 02115, USA 3Department of Biology, Northeastern University, Boston, MA 02115, USA Correspondence: [email protected] or [email protected] Increasing evidence suggests that ribosomes actively regulate protein synthesis. However, much of this evidence is indirect, leaving this layer of gene regulation largely unexplored, in part due to methodological limitations. Indeed, we review evidence demonstrating that commonly used methods, such as transcriptomics, are inadequate because the variability in mRNAs coding for ribosomal proteins (RP) does not necessarily correspond to RP variability. Thus protein remodeling of ribosomes should be investigated by methods that allow direct quantification of RPs, ideally of isolated ribosomes. We review such methods, focusing on mass spectrometry and emphasizing method-specific biases and approaches to control these biases. We argue that using multiple complementary methods can help reduce the danger of interpreting reproducible systematic biases as evidence for ribosome remodeling. Introduction The control of gene expression is crucial for all biological processes, from developmental stages and homeostasis maintenance to regeneration processes. This regulation occurs at multiple layers, both transcriptional and post-transcriptional levels. Historically, transcription has been studied more extensively than translation, in large part because of the accessibility of technologies for nucleic acid analysis. However, gene regulation via translation was appreciated as early as the late arXiv:2007.05839v2 [q-bio.QM] 2 Aug 2020 1960’s. For example, the production of insulin was linked to the increased number of polysomes and protein synthesis [1]. -
