The kinetic mechanism of bacterial ribosome recycling. [PDF]
, 2017 Bacterial ribosome recycling requires breakdown of the post-termination complex (PoTC), comprising a messenger RNA (mRNA) and an uncharged transfer RNA (tRNA) cognate to the terminal mRNA codon bound to the 70S ribosome.

Genome-wide Survey of Ribosome Collision
Cell 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 ...

RNA 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
eLife, 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.

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

Identifying ribosome heterogeneity using ribosome profiling
Nucleic 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.

Cell, 2001 The conversion of a ribosomal RNA transcript to a cytoplasmic ribosome requires hundreds of accessory RNA and protein factors. Two papers published recently in Molecular Cell provide first looks at the association of these processing factors with the intermediates in ribosome synthesis (Harnpicharnchai et al., 2001; Bassler et al., 2001).

eLife, 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 ...

HCV IRES manipulates the ribosome to promote the switch from translation initiation to elongation. [PDF]
, 2013 The internal ribosome entry site (IRES) of the hepatitis C virus (HCV) drives noncanonical initiation of protein synthesis necessary for viral replication.
