The Arabidopsis cytosolic ribosomal proteome: from form to function
Frontiers in Plant Science, 2013 The cytosolic ribosomal proteome of Arabidopsis thaliana has been studied intensively by a range of proteomics approaches and is now one of the best-characterised eukaryotic ribosomal proteomes.

Regulation of Ribosomal Proteins on Viral Infection
Cells, 2019 Ribosomal proteins (RPs), in conjunction with rRNA, are major components of ribosomes involved in the cellular process of protein biosynthesis, known as “translation”.

Studies on the Coordination of Ribosomal Protein Assembly Events Involved in Processing and Stabilization of Yeast Early Large Ribosomal Subunit Precursors. [PDF]
PLoS ONE, 2015 Cellular production of ribosomes involves the formation of highly defined interactions between ribosomal proteins (r-proteins) and ribosomal RNAs (rRNAs). Moreover in eukaryotic cells, efficient ribosome maturation requires the transient association of a

FEBS Letters, EarlyView.An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Synchronizing Nuclear Import of Ribosomal Proteins with Ribosome Assembly [PDF]
Science, 2012 Symportin Synchrony Ribosomes, the macromolecular machines responsible for protein synthesis, function in the cytoplasm but are assembled in the nucleus. Ribosomal proteins must be imported into the nucleus, but how this is coordinated with assembly is unclear. Kressler

FEBS Letters, EarlyView.Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Placeholder factors in ribosome biogenesis: please, pave my way
Microbial Cell, 2017 The synthesis of cytoplasmic eukaryotic ribosomes is an extraordinarily energy-demanding cellular activity that occurs progressively from the nucleolus to the cytoplasm.

rRNA maturation in yeast cells depleted of large ribosomal subunit proteins. [PDF]
PLoS ONE, 2009 The structural constituents of the large eukaryotic ribosomal subunit are 3 ribosomal RNAs, namely the 25S, 5.8S and 5S rRNA and about 46 ribosomal proteins (r-proteins).

FEBS Letters, EarlyView.The process of internalization of the Shiga toxin A subunit via formation of a complex with the Shiga toxin B subunit, which specifically binds to the Gb3 receptor. The peptide is designed to act as a carrier of drugs into cancer cells. Here, we explored the potential of peptides derived from the catalytic A subunit of Shiga toxin (STxA) to be drug ...

Ribosomal protein paralogues in ribosome specialization
Philosophical Transactions of the Royal Society B: Biological SciencesRibosomes are macromolecular complexes responsible for protein synthesis, comprising ribosomal proteins (RPs) and ribosomal RNA. While most RPs are present as single copies in higher eukaryotes, a handful of them have paralogues that emerged through duplication events.
