Homeostatic Roles of the Proteostasis Network in Dendrites

open access: yesFrontiers in Cellular Neuroscience, 2020
Cellular protein homeostasis, or proteostasis, is indispensable to the survival and function of all cells. Distinct from other cell types, neurons are long-lived, exhibiting architecturally complex and diverse multipolar projection morphologies that can ...

The dark side of the ribosome life cycle

open access: yesRNA Biology, 2022
Thanks to genetics, biochemistry, and structural biology many features of the ribosome´s life cycles in models of bacteria, eukaryotes, and some organelles have been revealed to near-atomic details.

General Approach for Introduction of Various Chemical Labels in Specific RNA Locations Based on Insertion of Amino Linkers

open access: yesMolecules, 2013
Introduction of reporter groups at designed RNA sites is a widely accepted approach to gain information about the molecular environment of RNAs in their complexes with other biopolymers formed during various cellular processes.

Genome-wide Survey of Ribosome Collision

open access: yesCell Reports, 2020
Summary: Ribosome movement is not always smooth and is rather often impeded. For ribosome pauses, fundamental issues remain to be addressed, including where ribosomes pause on mRNAs, what kind of RNA/amino acid sequence causes this pause, and the ...

Lamotrigine compromises the fidelity of initiator tRNA recruitment to the ribosomal P-site by IF2 and the RbfA release from 30S ribosomes in Escherichia coli

open access: yesRNA Biology, 2023
Lamotrigine (Ltg), an anticonvulsant drug, targets initiation factor 2 (IF2), compromises ribosome biogenesis and causes toxicity to Escherichia coli. However, our understanding of Ltg toxicity in E. coli remains unclear. While our in vitro assays reveal

Translation inhibitory elements from Hoxa3 and Hoxa11 mRNAs use uORFs for translation inhibition

open access: yeseLife, 2021
During embryogenesis, Hox mRNA translation is tightly regulated by a sophisticated molecular mechanism that combines two RNA regulons located in their 5’UTR. First, an internal ribosome entry site (IRES) enables cap-independent translation.

The ribosome assembly gene network is controlled by the feedback regulation of transcription elongation [PDF]

open access: yes, 2017
Ribosome assembly requires the concerted expression of hundreds of genes, which are transcribed by all three nuclear RNA polymerases. Transcription elongation involves dynamic interactions between RNA polymerases and chromatin.

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.

A nascent polypeptide sequence modulates DnaA translation elongation in response to nutrient availability

open access: yeseLife, 2021
The ability to regulate DNA replication initiation in response to changing nutrient conditions is an important feature of most cell types. In bacteria, DNA replication is triggered by the initiator protein DnaA, which has long been suggested to respond ...

Stochastic kinetics of ribosomes: single motor properties and collective behavior [PDF]

open access: yes, 2009
Synthesis of protein molecules in a cell are carried out by ribosomes. A ribosome can be regarded as a molecular motor which utilizes the input chemical energy to move on a messenger RNA (mRNA) track that also serves as a template for the polymerization ...
