Mechanistic insight into the efficient packaging of antigenomic S RNA into Rift Valley fever virus particles

open access: yesFrontiers in Cellular and Infection Microbiology, 2023
Rift Valley fever virus (RVFV), a bunyavirus, has a single-stranded, negative-sense tri-segmented RNA genome, consisting of L, M and S RNAs. An infectious virion carries two envelope glycoproteins, Gn and Gc, along with ribonucleoprotein complexes ...

Development of a Novel Competitive qRT-PCR Assay to Measure Relative Lentiviral Packaging Efficiency

open access: yesMolecular Therapy: Methods & Clinical Development, 2020
Third-generation HIV-1-derived lentiviral vectors are successfully used as therapeutic agents in various clinical applications. To further promote their use, we attempted to enhance vector infectivity by targeting the dimerization and packaging ...

Selective Packaging in Murine Coronavirus Promotes Virulence by Limiting Type I Interferon Responses

open access: yesmBio, 2018
Selective packaging is a mechanism used by multiple virus families to specifically incorporate genomic RNA (gRNA) into virions and exclude other types of RNA. Lineage A betacoronaviruses incorporate a 95-bp stem-loop structure, the packaging signal (PS),

Transcription Start Site Heterogeneity and Preferential Packaging of Specific Full-Length RNA Species Are Conserved Features of Primate Lentiviruses

open access: yesMicrobiology Spectrum, 2022
HIV-1 must package its RNA genome to generate infectious viruses. Recent studies have revealed that during genome packaging, HIV-1 not only excludes cellular mRNAs, but also distinguishes among full-length viral RNAs. Using NL4-3 and MAL molecular clones,

Expression of IMP1 enhances production of murine leukemia virus vector by facilitating viral genomic RNA packaging. [PDF]

open access: yesPLoS ONE, 2010
Murine leukemia virus (MLV)-based retroviral vector is widely used for gene transfer. Efficient packaging of the genomic RNA is critical for production of high-titer virus. Here, we report that expression of the insulin-like growth factor II mRNA binding

NMR Studies of Retroviral Genome Packaging

open access: yesViruses, 2020
Nearly all retroviruses selectively package two copies of their unspliced RNA genomes from a cellular milieu that contains a substantial excess of non-viral and spliced viral RNAs.

Alphavirus Nucleocapsid Packaging and Assembly

open access: yesViruses, 2018
Alphavirus nucleocapsids are assembled in the cytoplasm of infected cells from 240 copies of the capsid protein and the approximately 11 kb positive strand genomic RNA.

Dimerisation of HIV-2 genomic RNA is linked to efficient RNA packaging, normal particle maturation and viral infectivity

open access: yesRetrovirology, 2007
Background Retroviruses selectively encapsidate two copies of their genomic RNA, the Gag protein binding a specific RNA motif in the 5' UTR of the genome. In human immunodeficiency virus type 2 (HIV-2), the principal packaging signal (Psi) is upstream of

Dimeric RNA recognition regulates HIV-1 genome packaging.

open access: yesPLoS Pathogens, 2013
How retroviruses regulate the amount of RNA genome packaged into each virion has remained a long-standing question. Our previous study showed that most HIV-1 particles contain two copies of viral RNA, indicating that the number of genomes packaged is ...

MoMuLV and HIV-1 nucleocapsid proteins have a common role in genomic RNA packaging but different in late reverse transcription. [PDF]

open access: yesPLoS ONE, 2012
Retroviral nucleocapsid proteins harbor nucleic acid chaperoning activities that mostly rely on the N-terminal basic residues and the CCHC zinc finger motif.
