Polyproline motifs are essential structural features of many proteins, and recent evidence suggests that EF-P is one of several factors that facilitate their translation. For example, YfmR was recently identified as a protein that prevents ribosome stalling at proline-containing sequences in the absence of EF-P. Here, we show that the YebC-family protein YebC2 (formerly YeeI) functions as a translation factor in that resolves ribosome stalling at polyprolines.

Article Synopsis
  • RF2 is a special protein that helps stop the process of making proteins in bacteria.
  • Scientists studied a lot of bacteria to see how they use a special trick called frameshifting to control how much RF2 they make.
  • They found out that some bacteria don’t need this trick because they already produce the right amount of RF2, and using it too much can be harmful to them.

Despite its ubiquitous infectivity to mammals with strong host specificity, our current knowledge about has originated from studies of merely 4% of extant mammalian species. Further studies of epidemiology across a broader range of animal species require the use of assays with high sensitivity and specificity. To this end, we have developed multiple universal primers targeting different genetic loci with high amplification efficiency.

Background: Bloom Syndrome (BSyn) is an autosomal recessive disorder caused by biallelic germline variants in which functions to maintain genomic stability. BSyn patients have poor growth, immune defects, insulin resistance, and a significantly increased risk of malignancies, most commonly hematologic. The malignancy risk in carriers of pathogenic variants in ( variant carriers) remains understudied.

Article Synopsis
  • * The study involved analyzing genetic changes in individuals with BOS compared to healthy controls using advanced techniques that looked at chromatin accessibility, DNA methylation, and gene expression in different cell types.
  • * ASXL1 mutations were found to have widespread effects across tissues, notably activating Wnt signaling pathways, which may help identify potential treatments for both BOS and acute myeloid leukemia.

Frequent and widespread testing of members of the population who are asymptomatic for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is essential for the mitigation of the transmission of the virus. Despite the recent increases in testing capacity, tests based on quantitative polymerase chain reaction (qPCR) assays cannot be easily deployed at the scale required for population-wide screening. Here, we show that next-generation sequencing of pooled samples tagged with sample-specific molecular barcodes enables the testing of thousands of nasal or saliva samples for SARS-CoV-2 RNA in a single run without the need for RNA extraction.

The rapid spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is due to the high rates of transmission by individuals who are asymptomatic at the time of transmission. Frequent, widespread testing of the asymptomatic population for SARS-CoV-2 is essential to suppress viral transmission. Despite increases in testing capacity, multiple challenges remain in deploying traditional reverse transcription and quantitative PCR (RT-qPCR) tests at the scale required for population screening of asymptomatic individuals.
