Insight Into the Interaction Between RNA Polymerase and VPg for Murine Norovirus Replication

Frontiers in Microbiology, 2018
Norovirus (NoV) is a leading cause of epidemic acute non-bacterial gastroenteritis, and replicates through virion protein genome-linked (VPg)-primed or de novo RNA synthesis by RNA-dependent RNA polymerase (RdRp).

A Single ssRNA Segment Encoding RdRp Is Sufficient for Replication, Infection, and Transmission of Ourmia-Like Virus in Fungi

Frontiers in Microbiology, 2020
Recently, an increasing number of ourmia-like viruses have been found in fungi; however, the features of these viruses remain unknown. Here, we report a novel ourmia-like virus isolated from Sclerotinia sclerotiorum. This virus, named S.

A Lung‐Immune Dual‐Humanized Mouse Using Cryopreserved Tissue Enables Infection and Immune Profiling of Human Common Cold Coronaviruses

Advanced Science, EarlyView.
Cryopreserved lung‐humanized mice overcome the dependency to fresh tissues and permit head‐to‐head profiling of all four human common cold coronaviruses versus SARS‐CoV‐2 infection; the model validates Paxlovid efficacy against HKU1 and, when coupled with human immune‐system engraftment, enables interrogation of lung‐resident human immunity and HKU1 ...

Fidelity variants of RNA dependent RNA polymerases uncover an indirect, mutagenic activity of amiloride compounds. [PDF]

PLoS Pathogens, 2010
In a screen for RNA mutagen resistance, we isolated a high fidelity RNA dependent RNA polymerase (RdRp) variant of Coxsackie virus B3 (CVB3). Curiously, this variant A372V is also resistant to amiloride.

Antagonistic Ubiquitin Switching by USP7 and RNF40 Orchestrates KDM6A Homeostasis to License Coronavirus Susceptibility

Advanced Science, EarlyView.
We identify an antagonistic ubiquitin circuit that controls cellular permissiveness to multiple coronaviruses. The deubiquitinase USP7 stabilizes the epigenetic regulator KDM6A to upregulate viral receptors, while the E3 ligase RNF40 degrades KDM6A by catalyzing K6/K11‐ubiquitin chains of KDM6A for autophagic degradation.

NeoRdRp2 with improved seed data, annotations, and scoring

Frontiers in Virology
RNA-dependent RNA polymerase (RdRp) is a marker gene for RNA viruses; thus, it is widely used to identify RNA viruses from metatranscriptome data. However, because of the high diversity of RdRp domains, it remains difficult to identify RNA viruses using ...

The N-Terminal α-Helix of Potato Virus X-Encoded RNA-Dependent RNA Polymerase Is Required for Membrane Association and Multimerization

Viruses, 2022
Positive-sense single-stranded RNA viruses replicate in virus-induced membranous organelles for maximum efficiency and immune escaping. The replication of potato virus X (PVX) takes place on the endoplasmic reticulum (ER); however, how PVX-encoded RNA ...

“More” Artificial mRNAs: Beyond the Art of Nature

Advanced Science, EarlyView.
Inspired by nature yet transcending it, synthetic mRNA is being redesigned beyond the canonical architecture. This review highlights emerging forms—circular, branched, and self‐amplifying mRNAs—that expand stability, persistence, and functional control, illustrating how artificial mRNA is evolving into a new medium for programmable biological ...

Chicken Pulmonary MicroRNAs Targeting the PB2 (Segment 1) of Avian Influenza Virus

Animal Research and One Health, EarlyView.
The PB2 segment of H5N1 is essential for replication and host adaptation. We screened 200 miRNAs and identified five (gga‐miR‐17‐3p, gga‐miR‐29a‐5p, gga‐miR‐1718, gga‐miR‐16c‐5p, and gga‐miR‐1744‐5p) using thermodynamic stability of heteroduplex, seed sequence complementarity, conservation, and accessibility, offering insights into host antiviral ...
