The other lives of ribosomal proteins

Human Genomics, 2010
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,

Structures and Ribosomal Interaction of Ribosome-Inactivating Proteins [PDF]

Molecules, 2016
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 Modular Adaptive Ribosome. [PDF]

PLoS ONE, 2016
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]

Journal of Molecular Cell Biology, 2015
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,

Archaea/eukaryote-specific ribosomal proteins - guardians of a complex structure

Computational and Structural Biotechnology Journal, 2023
In three domains of life, proteins are synthesized by large ribonucleoprotein particles called ribosomes. All ribosomes are composed of ribosomal RNAs (rRNA) and numerous ribosomal proteins (r-protein).

Involvement of Target of Rapamycin (TOR) Signaling in the Regulation of Crosstalk between Ribosomal Protein Small Subunit 6 Kinase-1 (RPS6K-1) and Ribosomal Proteins

Plants, 2023
The target of rapamycin (TOR) protein phosphorylates its downstream effector p70kDa ribosomal protein S6 kinases (S6K1) for ribosome biogenesis and translation initiation in eukaryotes.

Studies on the assembly characteristics of large subunit ribosomal proteins in S. cerevisae. [PDF]

PLoS ONE, 2013
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 ...

Tagging of RPS9 as a tool for ribosome purification and identification of ribosome-associated proteins [PDF]

Archives of Biological Sciences, 2021
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]

European Journal of Biochemistry, 1973
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.
