Nucleotide sequence and genomic organization of an ophiovirus associated with lettuce big-vein disease [PDF]
The complete nucleotide sequence of an ophiovirus associated with lettuce big-vein disease has been elucidated. The genome consisted of four RNA molecules of approximately 7ò8, 1ò7, 1ò5 and 1ò4 kb.

Multi-protein bridging factor 1(Mbf1), Rps3 and Asc1 prevent stalled ribosomes from frameshifting
Reading frame maintenance is critical for accurate translation. We show that the conserved eukaryotic/archaeal protein Mbf1 acts with ribosomal proteins Rps3/uS3 and eukaryotic Asc1/RACK1 to prevent frameshifting at inhibitory CGA-CGA codon pairs in the ...

Ribosomal frameshifting on viral RNAs
Introduction. Accurate maintenance of the translational reading frame by ribosomes is essential for the production of functional proteins and unsurprisingly, errors in frame maintenance have been estimated to occur at rates probably lower than 5 × 10-5 per codon (Kurland, 1992).

Molecular model of ribosome frameshifting. [PDF]
Normal tRNAs can cause two- and four-base translocation errors by mistranslating certain noncognate codons. Several cases have been reported that reveal the identities of the frameshift-provoking tRNAs--i.e., the shifty tRNAs--and the mRNA sequence encompassing the site of frameshifting--i.e., the shifty codons.

The Translational Landscape of SARS-CoV-2-infected Cells Reveals Suppression of Innate Immune Genes
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) utilizes a number of strategies to modulate viral and host mRNA translation. Here, we used ribosome profiling in SARS-CoV-2-infected model cell lines and primary airway cells grown at an air ...

Ribosomal frameshifting, jumping and readthrough
New examples of high-level ribosomal frameshift and readthrough events have been described over the past year and a half. These include -1 frameshifting at tandem codons and +1 frameshifting at neighboring slow codons. Several bizarre examples of ribosome jumping and multiple stop-codon readthrough continue to perplex investigators in this field.

Candidates in Astroviruses, Seadornaviruses, Cytorhabdoviruses and Coronaviruses for +1 frame overlapping genes accessed by leaky scanning [PDF]
Background Overlapping genes are common in RNA viruses where they serve as a mechanism to optimize the coding potential of compact genomes. However, annotation of overlapping genes can be difficult using conventional gene-finding software.

Crystallographic studies of ribosomal frameshifting
A recent 2.8 Åcrystal structure of the 70S ribosome from Thermus thermophilus shows many details of how the ribosome interacts with its mRNA and tRNA substrates (1).

ABSTRACT Neisseria gonorrhoeae poses an urgent public health challenge due to rapidly increasing antimicrobial resistance and the absence of an effective vaccine. Targeting conserved bacterial pathways involved in essential physiological processes may provide new opportunities for vaccine antigen discovery.
