The Heat Shock Response in the Western Honey Bee (Apis mellifera) is Antiviral

Viruses, 2020
Honey bees (Apis mellifera) are an agriculturally important pollinator species that live in easily managed social groups (i.e., colonies). Unfortunately, annual losses of honey bee colonies in many parts of the world have reached unsustainable levels ...

Structures of influenza A and B replication complexes give insight into avian to human host adaptation and reveal a role of ANP32 as an electrostatic chaperone for the apo-polymerase

Nature Communications
Replication of influenza viral RNA depends on at least two viral polymerases, a parental replicase and an encapsidase, and cellular factor ANP32. ANP32 comprises an LRR domain and a long C-terminal low complexity acidic region (LCAR).

A Novel RNA Virus in the Parasitoid Wasp Lysiphlebus fabarum: Genomic Structure, Prevalence, and Transmission

Viruses, 2020
We report on a novel RNA virus infecting the wasp Lysiphlebus fabarum, a parasitoid of aphids. This virus, tentatively named “Lysiphlebus fabarum virus” (LysV), was discovered in transcriptome sequences of wasps from an experimental evolution

Novel Viruses in Mosquitoes from Brazilian Pantanal

Viruses, 2019
Viruses are ubiquitous and diverse microorganisms arising as a result of interactions within their vertebrate and invertebrate hosts. Here we report the presence of different viruses in the salivary glands of 1657 mosquitoes classified over 28 culicinae ...

Hepatitis C Virus RNA Replication [PDF]

, 2013
Genome replication is a crucial step in the life cycle of any virus. HCV is a positive strand RNA virus and requires a set of nonstructural proteins (NS3, 4A, 4B, 5A, and 5B) as well as cis-acting replication elements at the genome termini for amplification of the viral RNA.

Aminoacylation of Encephalomyocarditis Virus RNA

Journal of General Virology, 1977
RNA extracted from purified encephalomyocarditis (EMC) virus (EMC-RNA) can be aminoacylated with synthetase praparations from Escherichia coli, beef and rabbit liver. The extent of aminoacylation is between 0-024 and 0-080 moles per mole EMC-RNA and occurs only with serine. Either removal of possible low mol. wt.

RNA-protein interaction prediction without high-throughput data: An overview and benchmark of in silico tools

Computational and Structural Biotechnology Journal
RNA-protein interactions (RPIs) are crucial for accurately operating various processes in and between organisms across kingdoms of life. Mutual detection of RPI partner molecules depends on distinct sequential, structural, or thermodynamic features ...

Genome-scale CRISPR-Cas9 screen identifies host factors as potential therapeutic targets for SARS-CoV-2 infection

iScience
Summary: Although many host factors important for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection have been reported, the mechanisms by which the virus interacts with host cells remain elusive.

Distinct evolution of SARS-CoV-2 Omicron XBB and BA.2.86/JN.1 lineages combining increased fitness and antibody evasion

Nature Communications
The unceasing circulation of SARS-CoV-2 leads to the continuous emergence of novel viral sublineages. Here, we isolate and characterize XBB.1, XBB.1.5, XBB.1.9.1, XBB.1.16.1, EG.5.1.1, EG.5.1.3, XBF, BA.2.86.1 and JN.1 variants, representing >80% of ...
