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.

Disome-seq reveals widespread ribosome collisions that promote cotranslational protein folding

open access: yesGenome Biology, 2021
Background The folding of proteins is challenging in the highly crowded and sticky environment of a cell. Regulation of translation elongation may play a crucial role in ensuring the correct folding of proteins.

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.

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 ...

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 ...

Structure of the bacterial ribosome at 2 Å resolution

open access: yesbioRxiv, 2020
Continuing advances in cryo-electron microscopy (cryo-EM) demonstrate the promise it holds for revealing biological structures at chemical resolution, in which noncovalent interactions, RNA and protein modifications, and solvation can be modeled ...

HCV IRES manipulates the ribosome to promote the switch from translation initiation to elongation. [PDF]

open access: yes, 2013
The internal ribosome entry site (IRES) of the hepatitis C virus (HCV) drives noncanonical initiation of protein synthesis necessary for viral replication.

Bacterial riboproteogenomics : the era of N-terminal proteoform existence revealed [PDF]

open access: yes, 2020
With the rapid increase in the number of sequenced prokaryotic genomes, relying on automated gene annotation became a necessity. Multiple lines of evidence, however, suggest that current bacterial genome annotations may contain inconsistencies and are ...

Didemnin B and ternatin-4 differentially inhibit conformational changes in eEF1A required for aminoacyl-tRNA accommodation into mammalian ribosomes

open access: yeseLife, 2022
Rapid and accurate mRNA translation requires efficient codon-dependent delivery of the correct aminoacyl-tRNA (aa-tRNA) to the ribosomal A site. In mammals, this fidelity-determining reaction is facilitated by the GTPase elongation factor-1 alpha (eEF1A),

Hepatitis C virus 3'UTR regulates viral translation through direct interactions with the host translation machinery. [PDF]

open access: yes, 2013
The 3' untranslated region (3'UTR) of hepatitis C virus (HCV) messenger RNA stimulates viral translation by an undetermined mechanism. We identified a high affinity interaction, conserved among different HCV genotypes, between the HCV 3'UTR and the host ...
