The PDB and the ribosome [PDF]

open access: yesJournal of Biological Chemistry, 2021
This essay, which was written to commemorate the 50th anniversary of the Protein Data Bank, opens with some comments about the intentions of the scientists who pressed for its establishment and the nature of services it provides. It includes a brief account of the events that resulted in the determination of the crystal structure of the large ribosomal

Expansion of a novel population of NK cells with low ribosome expression in juvenile dermatomyositis

open access: yesFrontiers in Immunology, 2022
Juvenile dermatomyositis (JDM) is a pediatric autoimmune disease associated with characteristic rash and proximal muscle weakness. To gain insight into differential lymphocyte gene expression in JDM, peripheral blood mononuclear cells from 4 new-onset ...

Ribosomal proteins: functions beyond the ribosome [PDF]

open access: yesJournal 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,

Kinetic modeling predicts a stimulatory role for ribosome collisions at elongation stall sites in bacteria

open access: yeseLife, 2017
Ribosome stalling on mRNAs can decrease protein expression. To decipher ribosome kinetics at stall sites, we induced ribosome stalling at specific codons by starving the bacterium Escherichia coli for the cognate amino acid. We measured protein synthesis

Identifying ribosome heterogeneity using ribosome profiling

open access: yesNucleic Acids Research, 2022
Abstract Recent studies have revealed multiple mechanisms that can lead to heterogeneity in ribosomal composition. This heterogeneity can lead to preferential translation of specific panels of mRNAs, and is defined in large part by the ribosomal protein (RP) content, amongst other things.

Molecular Dynamics Simulations Suggest a Non-Doublet Decoding Model of −1 Frameshifting by tRNASer3

open access: yesBiomolecules, 2019
In-frame decoding in the ribosome occurs through canonical or wobble Watson−Crick pairing of three mRNA codon bases (a triplet) with a triplet of anticodon bases in tRNA.

Application of fluorescence correlation spectroscopy to investigate the dynamics of a ribosome-associated trigger factor in Escherichia coli

open access: yesFrontiers in Molecular Biosciences, 2022
Co-translational protein folding is one of the central topics in molecular biology. In Escherichia coli, trigger factor (TF) is a primary chaperone that facilitates co-translational folding by directly interacting with nascent polypeptide chains on ...

Alkylative damage of mRNA leads to ribosome stalling and rescue by trans translation in bacteria

open access: yeseLife, 2020
Similar to DNA replication, translation of the genetic code by the ribosome is hypothesized to be exceptionally sensitive to small chemical changes to its template mRNA.

How Ricin Damages the Ribosome

open access: yesToxins, 2019
Ricin belongs to the group of ribosome-inactivating proteins (RIPs), i.e., toxins that have evolved to provide particular species with an advantage over other competitors in nature.
