APE-type non-LTR retrotransposons of multicellular organisms encode virus-like 2A oligopeptide sequences, which mediate translational recoding during protein synthesis

open access: yes, 2013
2A oligopeptide sequences (“2As”) mediate a cotranslational recoding event termed “ribosome skipping.” Previously we demonstrated the activity of 2As (and “2A-like sequences”) within a wide range of animal RNA virus genomes and non-long terminal repeat ...

Multiplex base editing to convert TAG into TAA codons in the human genome

open access: yesNature Communications, 2021
Whole-genome recoding has been shown to enable nonstandard amino acids, biocontainment and viral resistance in bacteria. Here we take the first steps to extend this to human cells demonstrating exceptional base editing to convert TAG to TAA for 33 ...

Genomic Recoding Broadly Obstructs the Propagation of Horizontally Transferred Genetic Elements [PDF]

open access: yesCell Systems, 2016
Horizontally transferred genetic elements such as viruses and conjugative plasmids move DNA between organisms, increasing genetic diversity but destabilizing engineered biological systems. Here, we used a genomically recoded Escherichia coli strain lacking UAG stop codons and the recognition protein release factor 1 to study how an alternative genetic ...

Genome Analysis of a Verrucomicrobial Endosymbiont With a Tiny Genome Discovered in an Antarctic Lake

open access: yesFrontiers in Microbiology, 2021
Organic Lake in Antarctica is a marine-derived, cold (−13∘C), stratified (oxic-anoxic), hypersaline (>200 gl–1) system with unusual chemistry (very high levels of dimethylsulfide) that supports the growth of phylogenetically and metabolically diverse ...

High-throughput proteogenomics of Ruegeria pomeroyi: seeding a better genomic annotation for the whole marine Roseobacter clade [PDF]

open access: yes, 2012
Background The structural and functional annotation of genomes is now heavily based on data obtained using automated pipeline systems. The key for an accurate structural annotation consists of blending similarities between closely related genomes with ...

CpG content in the Zika virus genome affects infection phenotypes in the adult brain and fetal lymph nodes

open access: yesFrontiers in Immunology, 2022
Increasing the number of CpG dinucleotides in RNA viral genomes, while preserving the original amino acid composition, leads to impaired infection which does not cause disease.

Strategies to identify and edit improvements in synthetic genome segments episomally

open access: yesbioRxiv, 2022
Genome engineering projects often utilize bacterial artificial chromosomes (BACs) to carry multi-kilobase DNA segments on low copy number vectors. However, DNA synthesis and amplification have the potential to impose mutations on the contained DNA ...

Systematic Evolution and Study of UAGN Decoding tRNAs in a Genomically Recoded Bacteria [PDF]

open access: yesScientific Reports, 2016
AbstractWe report the first systematic evolution and study of tRNA variants that are able to read a set of UAGN (N = A, G, U, C) codons in a genomically recoded E. coli strain that lacks any endogenous in-frame UAGN sequences and release factor 1. Through randomizing bases in anticodon stem-loop followed by a functional selection, we identified tRNA ...

PROGRAMMED TRANSLATIONAL RECODING SIGNALS AS A THERAPEUTIC TARGET AGAINST ALPHAVIRUSES [PDF]

open access: yes, 2018
While infection from communicable diseases has posed a longstanding threat to human health throughout history, the modern realities of population expansion, global travel, and climate change have facilitated the rapid emergence and worldwide distribution

Genomic Structural Variations Provide Insights Into Litter Size and Teat Number Traits in Hu Sheep

open access: yesAnimal Research and One Health, EarlyView.
Here, we conducted whole genome sequencing on 300 Hu sheep with an average depth of 16.51X. Two candidate genes associated with litter size and teat number traits were identified, namely MAST2 and AFDN. ABSTRACT Litter size and the teat number are important economic indicators in sheep production.
