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 ...

Cooperative Mechanism of RNA Packaging Motor [PDF]

open access: yesJournal of Biological Chemistry, 2005
P4 is a hexameric ATPase that serves as the RNA packaging motor in double-stranded RNA bacteriophages from the Cystoviridae family. P4 shares sequence and structural similarities with hexameric helicases. A structure-based mechanism for mechano-chemical coupling has recently been proposed for P4 from bacteriophage phi12.

Cell biology of retroviral RNA packaging [PDF]

open access: yesRNA Biology, 2011
Generation of infectious retroviral particles rely on the targeting of all structural components to the correct cellular sites at the correct time. Gag, the main structural protein, orchestrates the assembly process and the mechanisms that trigger its targeting to assembly sites are well described. Gag is also responsible for the packaging of the viral

Packaging of Genomic RNA in Positive-Sense Single-Stranded RNA Viruses: A Complex Story

open access: yesViruses, 2019
The packaging of genomic RNA in positive-sense single-stranded RNA viruses is a key part of the viral infectious cycle, yet this step is not fully understood. Unlike double-stranded DNA and RNA viruses, this process is coupled with nucleocapsid assembly.

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 ...

Packaging signals in single-stranded RNA viruses: nature’s alternative to a purely electrostatic assembly mechanism [PDF]

open access: yes, 2013
The formation of a protective protein container is an essential step in the life-cycle of most viruses. In the case of single-stranded (ss)RNA viruses, this step occurs in parallel with genome packaging in a co-assembly process.

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,

Is HIV-1 RNA dimerization a prerequisite for packaging? Yes, no, probably? [PDF]

open access: yes, 2004
During virus assembly, all retroviruses specifically encapsidate two copies of full-length viral genomic RNA in the form of a non-covalently linked RNA dimer.

pyrpipe : a Python package for RNA-Seq workflows [PDF]

open access: yesNAR Genomics and Bioinformatics, 2020
Abstract The availability of terabytes of RNA-Seq data and continuous emergence of new analysis tools, enable unprecedented biological insight. There is a pressing requirement for a framework that allows for fast, efficient, manageable, and reproducible RNA-Seq analysis.
