Inhibitors of Venezuelan Equine Encephalitis Virus Identified Based on Host Interaction Partners of Viral Non-Structural Protein 3

Viruses, 2021
Venezuelan equine encephalitis virus (VEEV) is a new world alphavirus and a category B select agent. Currently, no FDA-approved vaccines or therapeutics are available to treat VEEV exposure and resultant disease manifestations. The C-terminus of the VEEV

The SARS-Coronavirus PLnc domain of nsp3 as a replication/transcription scaffolding protein

Virus Research, 2008
Many genetic and mechanistic features distinguish the coronavirus replication machinery from that encoded by most other RNA viruses. The coronavirus replication/transcription complex is an assembly of viral and, most probably, cellular proteins that mediate the synthesis of both the unusually large (approximately 30 kb) RNA genome and an extensive set ...

The Chikungunya virus nsP3 macro domain inhibits activation of the NF-κB pathway [PDF]

Viruses, 2019
Abstract The role of the chikungunya virus (CHIKV) non-structural protein 3 (nsP3) in the virus lifecycle is poorly understood. The protein comprises 3 domains. The N-terminus is a macro domain, biochemically characterised to bind both RNA and ADP-ribose, and to possess ADP-ribosyl hydrolase activity – an enzymatic activity that removes

nsP3-FXR co-condensation enables alphavirus replication and reveals a targetable alphavirus vulnerability

Cell Reports
Summary: Alphaviruses are mosquito-borne RNA viruses that pose a significant threat to humans, with risks worsened by global warming. Non-structural protein 3 (nsP3) is critical for alphavirus infection, yet its precise roles remain poorly defined. Using

SNAP-tagged Chikungunya Virus Replicons Improve Visualisation of Non-Structural Protein 3 by Fluorescence Microscopy

Scientific Reports, 2017
Chikungunya virus (CHIKV), a mosquito-borne alphavirus, causes febrile disease, muscle and joint pain, which can become chronic in some individuals. The non-structural protein 3 (nsP3) plays essential roles during infection, but a complete understanding ...

Genome-wide analysis of protein–protein interactions and involvement of viral proteins in SARS-CoV-2 replication

Cell & Bioscience, 2021
Background Analysis of viral protein–protein interactions is an essential step to uncover the viral protein functions and the molecular mechanism for the assembly of a viral protein complex.

SARS-CoV-2 proteases PLpro and 3CLpro cleave IRF3 and critical modulators of inflammatory pathways (NLRP12 and TAB1): implications for disease presentation across species

Emerging Microbes and Infections, 2021
The genome of SARS-CoV-2 encodes two viral proteases (NSP3/papain-like protease and NSP5/3C-like protease) that are responsible for cleaving viral polyproteins during replication.

Inhibitors Targeting SARS‐CoV‐2 Papain‐Like Protease: Screening, Design, Synthesis, and Biological Evaluation

ChemMedChem, Volume 21, Issue 9, 14 May 2026.
In our study, we obtained both non‐covalent and covalent PLpro inhibitors. Additionally, the stable protein‐ligand interactions of the active compound were examined using advanced computational docking and molecular dynamics simulations. The non‐covalent inhibitor 2t showed antiviral activity with an EC50 of 2.89 µM, indicating its potential as a ...

Adapted Live SARS‐CoV‐2 Vaccine Elicits Rapid Mucosal Immunity, Protects From Disease, and Reduces Shedding of XBB.1.5

European Journal of Immunology, Volume 56, Issue 5, May 2026.
An attenuated live vaccine (OTS‐300) expressing the XBB.1.5 Spike provided rapid and complete protection against homologous challenge in the hamster model, accompanied by fast systemic and mucosal antibody responses and markedly reduced transmission compared with XBB.1.5 mRNA vaccination.

High-resolution functional mapping of the venezuelan equine encephalitis virus genome by insertional mutagenesis and massively parallel sequencing. [PDF]

PLoS Pathogens, 2010
We have developed a high-resolution genomic mapping technique that combines transposon-mediated insertional mutagenesis with either capillary electrophoresis or massively parallel sequencing to identify functionally important regions of the Venezuelan ...
