Structures and Ribosomal Interaction of Ribosome-Inactivating Proteins [PDF]
Ribosome-inactivating proteins (RIPs) including ricin, Shiga toxin, and trichosanthin, are RNA N-glycosidases that depurinate a specific adenine residue (A-4324 in rat 28S ribosomal RNA, rRNA) in the conserved α-sarcin/ricin loop (α-SRL) of rRNA.

The other lives of ribosomal proteins [PDF]
Despite the fact that ribosomal proteins are the constituents of an organelle that is present in every cell, they show a surprising level of regulation, and several of them have also been shown to have other extra-ribosomal functions, such in replication,

Cotranslational folding of proteins on the ribosome. [PDF]
Many proteins in the cell fold cotranslationally within the restricted space of the polypeptide exit tunnel or at the surface of the ribosome. A growing body of evidence suggests that the ribosome can alter the folding trajectory in many different ways ...

Ribosome Biogenesis and Cancer: Overview on Ribosomal Proteins [PDF]
Cytosolic ribosomes (cytoribosomes) are macromolecular ribonucleoprotein complexes that are assembled from ribosomal RNA and ribosomal proteins, which are essential for protein biosynthesis. Mitochondrial ribosomes (mitoribosomes) perform translation of the proteins essential for the oxidative phosphorylation system. The biogenesis of cytoribosomes and

The Modular Adaptive Ribosome. [PDF]
The ribosome is an ancient machine, performing the same function across organisms. Although functionally unitary, recent experiments suggest specialized roles for some ribosomal proteins.

Ribosomal proteins: functions beyond the ribosome [PDF]
Although ribosomal proteins are known for playing an essential role in ribosome assembly and protein translation, their ribosome-independent functions have also been greatly appreciated. Over the past decade, more than a dozen of ribosomal proteins have been found to activate the tumor suppressor p53 pathway in response to ribosomal stress. In addition,

Tagging of RPS9 as a tool for ribosome purification and identification of ribosome-associated proteins [PDF]
Ribosomes, the catalytic machinery required for protein synthesis, are comprised of 4 ribosomal RNAs and about 80 ribosomal proteins in mammals. Ribosomes further interact with numerous associated factors that regulate their biogenesis and function.

Evolution of Ribosomal Proteins [PDF]
We have studied the evolution of ribosomal proteins over a spectrum of 13 species ranging from man to plants using a two‐dimensional polyacrylamide gel electrophoresis technique. We tried to quantify the proximity of these species by coelectrophoresing the proteins from various combinations of two species.

Ribosome specialization in cancer: a spotlight on ribosomal proteins. [PDF]
AbstractIn the past few decades, our view of ribosomes has changed substantially. Rather than passive machines without significant variability, it is now acknowledged that they are heterogeneous, and have direct regulatory capacity. This ‘ribosome heterogeneity’ comes in many flavors, including in both the RNA and protein components of ribosomes, so ...

Studies on the assembly characteristics of large subunit ribosomal proteins in S. cerevisae. [PDF]
During the assembly process of ribosomal subunits, their structural components, the ribosomal RNAs (rRNAs) and the ribosomal proteins (r-proteins) have to join together in a highly dynamic and defined manner to enable the efficient formation of ...
