Pyrimidone inhibitors targeting Chikungunya Virus nsP3 macrodomain by fragment-based drug design.
The macrodomain of nsP3 (nsP3MD) is highly conserved among the alphaviruses and ADP-ribosylhydrolase activity of Chikungunya Virus (CHIKV) nsP3MD is critical for CHIKV viral replication and virulence.

The Chikungunya Virus nsP3 Macro Domain Inhibits Activation of the NF-κB Pathway. [PDF]
AbstractThe 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 ADP-ribose from ...

Challenging the Roles of NSP3 and Untranslated Regions in Rotavirus mRNA Translation. [PDF]
Rotavirus NSP3 is a translational surrogate of the PABP-poly(A) complex for rotavirus mRNAs. To further explore the effects of NSP3 and untranslated regions (UTRs) on rotavirus mRNAs translation, we used a quantitative in vivo assay with simultaneous ...

Interactions of Alphavirus nsP3 Protein with Host Proteins [PDF]
Alphaviruses are members of the Togaviridae family and are grouped into two categories: arthritogenic and encephalitic. Arthritogenic alphavirus infections, as the name implies, are associated with arthritic outcomes while encephalitic alphavirus ...

Involvement of PRRSV NSP3 and NSP5 in the autophagy process
Background Autophagy is an essential process in eukaryotic cells in which autophagosomes form to deliver cellular organelles and long-lived proteins to lysosomes for degradation. Many studies have recently identified the regulatory mechanisms involved in

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