Enhancing the Outcome of Crystallographic Fragment Screening by Choosing the Optimal Protein Crystal Form

Small Science, Volume 6, Issue 3, March 2026.
The selection of the crystal form impacts crystallographic fragment screening (CFS) hit rates. Almost identical CFS campaigns using monoclinic versus orthorhombic crystals of SARS‐CoV‐2 main protease yield hit rates of 3% and 16%. The higher hit rate correlates with larger solvent channels and a less constrained active site in the orthorhombic form ...

Rotavirus Protein NSP3 Shuts Off Host Cell Protein Synthesis

Virology, 2002
A recombinant vaccinia virus encoding rotavirus protein NSP3 driven by an internal ribosome entry site (IRES) from the encephalomyocarditis (EMC) virus was able to abate protein synthesis in BSC1 cells by 25-fold, with as much as 30% of the remaining protein synthesis being NSP3.

Toward Dual‐Function Nanoparticle Platforms for Arboviral Diagnostics and Vaccines: Advances, Challenges, and Future Prospects

Nano Select, Volume 7, Issue 2, February 2026.
This review explores nanoparticle (NP)‐based biosensors and nanovaccine platforms for arboviral infections, highlighting their design, performance, and translational potential. By comparing case studies across viruses, it identifies gold‐standard nanomaterials such as gold NPs (AuNPs), zinc oxide NPs (ZnONPs), molybdenum disulfide (MoS2) nanocomposites,

Comparative Interactome Profiling of Nonstructural Protein 3 Across SARS-CoV-2 Variants Emerged During the COVID-19 Pandemic

Viruses
SARS-CoV-2 virus and its variants remain a global health threat, due to their capacity for rapid evolution. Variants throughout the COVID-19 pandemic exhibited variations in virulence, impacting vaccine protection and disease severity.

RNAi Regulator C3PO Promotes Arbovirus Infection in Insect Vectors

Advanced Science, Volume 13, Issue 4, 19 January 2026.
RNA interference (RNAi) is vital for eukaryotes to defend against virus infection. The C3PO complex takes part in RNAi but its role in regulating viral infection remains unclear. This work finds that insect C3PO facilitates arbovirus replication by degrading precursors of miRNAs, especially miR‐971‐3p.

Antagonism of mosquito innate immunity by the chikungunya virus nsP3 protein

Access Microbiology, 2019
Chikungunya virus (CHIKV) is a re-emerging Alphavirus transmitted by Aedes mosquitos and causing fever, rash and chronic arthralgia. There are no vaccines or antiviral agents available for CHIKV therefore it is important to understand the molecular details of virus replication.

READDI protocol: Crystallisation of CHIKV nsP3 macrodomain v1

Chikungunya virus (CHIKV) causes severe fever, rash and debilitating joint pain that can last for months or even years. Millions of people have been infected with CHIKV, mostly in low- and middle-income countries, and the virus continues to spread into new areas due to the geographical expansion of its mosquito hosts.

Venezuelan equine encephalitis virus non-structural protein 3 dictates superinfection exclusion in mammalian cells

npj Viruses
Superinfection exclusion (SIE) prevents secondary infections of already infected cells. Arthritogenic alphaviruses induce SIE via early proteolytical cleavage of replicase precursor by non-structural protein 2 (nsP2).

Cryo-EM reveals a double oligomeric ring scaffold of the CHIKV nsP3 peptide in complex with the NTF2L domain of host G3BP1

mBio
Chikungunya virus (CHIKV) poses a severe threat to global public health. The interaction between CHIKV nsP3 and host G3BP1 is critical for viral replication. However, the exact structural mechanism of the nsP3–G3BP1 interaction is scarce. Here, we report
