Extensive evolution of cereal ribosome-inactivating proteins translates into unique structural features, activation mechanisms, and physiological roles [PDF]

open access: yes, 2017
Ribosome-inactivating proteins (RIPs) are a class of cytotoxic enzymes that can depurinate rRNAs thereby inhibiting protein translation. Although these proteins have also been detected in bacteria, fungi, and even some insects, they are especially ...

The Arabidopsis cytosolic ribosomal proteome: from form to function

open access: yesFrontiers 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.

Ribosomal proteins produced in excess are degraded by the ubiquitin-proteasome system [PDF]

open access: yes, 2016
Ribosome assembly is an essential process that consumes prodigious quantities of cellular resources. Ribosomal proteins cannot be overproduced in Saccharomyces cerevisiae because the excess proteins are rapidly degraded.

Bacterial protein interaction networks: connectivity is ruled by gene conservation, essentiality and function [PDF]

open access: yes, 2020
Protein-protein interaction (PPI) networks are the backbone of all processes in living cells. In this work we relate conservation, essentiality and functional repertoire of a gene to the connectivity $k$ of the corresponding protein in the PPI networks ...

Transcription-translation coupling: direct interactions of RNA polymerase with ribosomes and ribosomal subunits. [PDF]

open access: yes, 2017
In prokaryotes, RNA polymerase and ribosomes can bind concurrently to the same RNA transcript, leading to the functional coupling of transcription and translation.

Regulation of Ribosomal Proteins on Viral Infection

open access: yesCells, 2019
Ribosomal proteins (RPs), in conjunction with rRNA, are major components of ribosomes involved in the cellular process of protein biosynthesis, known as “translation”.

rRNA maturation in yeast cells depleted of large ribosomal subunit proteins. [PDF]

open access: yesPLoS 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).

Studies on the Coordination of Ribosomal Protein Assembly Events Involved in Processing and Stabilization of Yeast Early Large Ribosomal Subunit Precursors. [PDF]

open access: yesPLoS 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

Yeast Rrp8p, a novel methyltransferase responsible for m1A 645 base modification of 25S rRNA [PDF]

open access: yes, 2012
Ribosomal RNA undergoes various modifications to optimize ribosomal structure and expand the topological potential of RNA. The most common nucleotide modifications in ribosomal RNA (rRNA) are pseudouridylations and 2'-O methylations (Nm), performed by H ...

Microtubule-dependent ribosome localization in C. elegans neurons. [PDF]

open access: yes, 2017
Subcellular localization of ribosomes defines the location and capacity for protein synthesis. Methods for in vivo visualizing ribosomes in multicellular organisms are desirable in mechanistic investigations of the cell biology of ribosome dynamics. Here,
