recommendations! Published in 2024 at "Journal of Plant Diseases and Protection"

DOI: 10.1007/s41348-024-00941-x

Abstract: Significant economic losses are inflicted by plant viruses, which pose a risk to sustainable agriculture. The proliferation of novel viral diseases is predominantly attributable to factors such as climate change, international trade, and the rapid… read more here.

DOI: 10.1016/j.antiviral.2020.104947

Abstract: Several fatal bunyavirus infections lack specific treatment. Here, we show that diketo acids engage a panel of bunyavirus cap-snatching endonucleases, inhibit their catalytic activity and reduce viral replication of a taxonomic representative in vitro. Specifically,… read more here.

recommendations! Published in 2020 at "Cell"

DOI: 10.1016/j.cell.2020.05.044

Abstract: Some negative-sense RNA viruses prime mRNA transcription using host 5' cap sequences, usurping host translational machinery and evading antiviral surveillance. In this issue of Cell, Ho et al. identify an additional consequence of this viral strategy:… read more here.

recommendations! Published in 2019 at "Trends in Microbiology"

DOI: 10.1016/j.tim.2018.12.013

Abstract: The influenza virus RNA-dependent RNA polymerase (RdRP) cleaves the 5′ end of nascent capped host RNAs and uses the capped RNA fragment to prime viral transcription in a mechanism called ‘cap snatching’. Cap snatching requires… read more here.

DOI: 10.1093/nar/gkz838

Abstract: Abstract Toscana virus (TOSV) is an arthropod-borne human pathogen responsible for seasonal outbreaks of fever and meningoencephalitis in the Mediterranean basin. TOSV is a segmented negative-strand RNA virus (sNSV) that belongs to the genus phlebovirus… read more here.

DOI: 10.1128/jvi.02173-21

Abstract: The Bunyavirales contain many important human pathogens such as Crimean-Congo hemorrhagic fever virus and Lassa virus that pose serious threats to public health; however, currently there are no specific antiviral drugs against these viruses. The… read more here.

DOI: 10.1128/spectrum.03289-24

Abstract: ABSTRACT The order Bunyavirales consists of over 300 species of segmented, negative-strand RNA viruses. These viruses have a tri-segmented genome (S, M, and L segments) that encodes the nucleocapsid protein (N protein), glycoprotein precursor, and… read more here.

DOI: 10.1261/rna.073866.119

Abstract: Influenza A virus (IAV) utilizes cap-snatching to obtain host capped small RNAs for priming viral mRNA synthesis, generating capped hybrid mRNAs for translation. Previous studies have been focusing on canonical cap-snatching, which occurs at the… read more here.

Bunyaviral N Proteins Localize at RNA Processing Bodies and Stress Granules: The Enigma of Cytoplasmic Sources of Capped RNA for Cap Snatching

Sign Up to like & get
recommendations! Published in 2022 at "Viruses"

DOI: 10.3390/v14081679

Abstract: Most cytoplasmic-replicating negative-strand RNA viruses (NSVs) initiate genome transcription by cap snatching. The source of host mRNAs from which the cytoplasmic NSVs snatch capped-RNA leader sequences has remained elusive. Earlier reports have pointed towards cytoplasmic-RNA… read more here.
