The DMV pore-forming TM2–Y region of SARS-CoV-2 nsp3 exhibits structural conservation beyond the coronavirus family [PDF]
Positive-strand RNA viruses remodel host intracellular membranes to form replication organelles in the cytoplasm. SARS-CoV-2 and other coronaviruses, members of the Nidovirales order, replicate within double-membrane vesicles (DMVs) derived from the ...

SARS-CoV-2 nonstructural protein 3 remodels the phosphorylation of target proteins via protein-protein interactions [PDF]
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of coronavirus disease 2019 (COVID-19), triggered a global pandemic with a significant impact on human health. The molecular basis of its pathogenicity remains incompletely

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

Extending the Targets for Coronavirus Antivirals Beyond That of Approved Drugs: Insights From Preclinical Research [PDF]
Chemical structure of RIBOTAC inhibitor with metabolic handle binding as nucleotide analogue to SARS‐CoV‐2 RNA dependent RNA polymerase, its linker and the RNase L recruiter which binds RNase L monomers and mediates their dimerization that actives nuclease activity degrading the viral RNA.

Structural and functional analyses of SARS-CoV-2 Nsp3 and its specific interactions with the 5’ UTR of the viral genome [PDF]
Non-structural protein 3 (Nsp3) is the largest open reading frame encoded in the SARS-CoV-2 genome, essential for the formation of double-membrane vesicles (DMV) wherein viral RNA replication occurs.

A structural roadmap for the formation of the coronavirus nsp3/nsp4 double membrane vesicle pore and its implications for polyprotein processing and replication/transcription [PDF]
Coronavirus replication is understood to occur within double membrane vesicles (DMVs) that arise during viral infection. Prior work has determined that these DMVs have characteristic pores formed from the non-structural viral proteins nsp3 and nsp4 ...

Alphaviral Capsid Proteins Inhibit Stress Granule Assembly via Competitive RNA Binding With G3BP1 [PDF]
Stress granules exert antiviral functions. This study illustrates a conserved function of alphaviral capsid proteins in modulating stress granules. Oligomerization mediated by a helical motif coupled with a positively charged intrinsically disordered region (IDR) directly competes with G3BP1 for RNA binding, thereby disrupting G3BP1‐RNA liquid–liquid ...
