Ancestral Interactions of Ribosomal RNA and Ribosomal Proteins [PDF]

Biophysical Journal, 2017
We have proposed that the ancient ribosome increased in size during early evolution by addition of small folding-competent RNAs. In this Accretion Model, small RNAs and peptides were subsumed onto subunit surfaces, gradually encasing and freezing previously acquired components.

Alterations in the ribosomal machinery in cancer and hematologic disorders

Journal of Hematology & Oncology, 2012
Ribosomes are essential components of the protein translation machinery and are composed of more than 80 unique large and small ribosomal proteins. Recent studies show that in addition to their roles in protein translation, ribosomal proteins are also ...

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).

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.

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

Ribosome-Inactivating and Related Proteins [PDF]

Toxins, 2015
Ribosome-inactivating proteins (RIPs) are toxins that act as N-glycosidases (EC 3.2.2.22). They are mainly produced by plants and classified as type 1 RIPs and type 2 RIPs. There are also RIPs and RIP related proteins that cannot be grouped into the classical type 1 and type 2 RIPs because of their different sizes, structures or functions. In addition,

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”.

Mapping of the saccharomyces cerevisiae oxa1-mitochondrial ribosome interface and identification of MrpL40, a ribosomal protein in close proximity to oxal and critical for oxidative phosphorylation complex assembly [PDF]

, 2009
The Oxa1 protein plays a central role in facilitating the cotranslational insertion of the nascent polypeptide chains into the mitochondrial inner membrane. Mitochondrially encoded proteins are synthesized on matrix-localized ribosomes which are tethered
