Programmed ribosomal frameshifting (PRF) is a fundamental gene expression event in many viruses, including SARS-CoV-2. It allows production of essential viral structural and replicative enzymes that are encoded in an alternative reading frame. Despite the importance of PRF for the viral life cycle, ...

Massively parallel reporter assay for programmed ribosomal frameshifting on designed sequence libraries
Start codon-associated ribosomal frameshifting mediates nutrient stress adaptation
Structural basis of ribosomal frameshifting during translation of the SARS-CoV-2 RNA genome
BSR cells were infected with the Cardiovirus B archetype, Theiler’s murine encephalomyelitis virus (TMEV), and mutants thereof, and subjected to ribosome profiling to analyse the viral translatome, frameshifting, and ribosome pausing events. Samples were harvested at 10 hpi by flash-freezing, withou...

Programmed ribosomal frameshifting is the key event during translation of the SARS-CoV-2 RNA genome allowing synthesis of the viral RNA-dependent RNA polymerase and downstream viral proteins. Here we present the cryo-EM structure of the mammalian ribosome in the process of translating viral RNA paus...

Ribosomal frameshifting at normal codon repeats recodes functional chimeric proteins in human [RNA-seq]
Ribosomal frameshifting at normal codon repeats recodes functional chimeric proteins in human[ChIP-seq]
We designed an oligonucleotide libraries containing a potential frameshifting site, cloned the library variants into a dedicated reporter construct, transfected and integrated these constructs in the genome of K562 cells, and performed FACSseq (as well as targeted RNA sequencing) to determine if and...
