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.

Transient SARS-CoV-2 RNA-Dependent RNA Polymerase Mutations after Remdesivir Treatment for Chronic COVID-19 in Two Transplant Recipients: Case Report and Intra-Host Viral Genomic Investigation

Microorganisms, 2023
Remdesivir is the first FDA-approved drug for treating severe SARS-CoV-2 infection and targets RNA-dependent RNA polymerase (RdRp) that is required for viral replication.

COVID‐2019: The role of the nsp2 and nsp3 in its pathogenesis [PDF]

Journal of Medical Virology, 2020
AbstractLast December 2019, a new virus, named novel Coronavirus (COVID‐2019) causing many cases of severe pneumonia was reported in Wuhan, China. The virus knowledge is limited and especially about COVID‐2019 pathogenesis. The Open Reading Frame 1ab (ORF1ab) of COVID‐2019 has been analyzed to evidence the presence of mutation caused by selective ...

Identification of a non-canonical G3BP-binding sequence in a Mayaro virus nsP3 hypervariable domain

Frontiers in Cellular and Infection Microbiology, 2022
Ras-GTPase-activating SH3 domain-binding-proteins 1 (G3BP1) and 2 (G3BP2) are multifunctional RNA-binding proteins involved in stress granule nucleation, previously identified as essential cofactors of Old World alphaviruses.

The Putative Roles and Functions of Indel, Repetition and Duplication Events in Alphavirus Non-Structural Protein 3 Hypervariable Domain (nsP3 HVD) in Evolution, Viability and Re-Emergence

Viruses, 2021
Alphavirus non-structural proteins 1–4 (nsP1, nsP2, nsP3, and nsP4) are known to be crucial for alphavirus RNA replication and translation. To date, nsP3 has been demonstrated to mediate many virus–host protein–protein interactions in several fundamental

SARS-CoV-2 nucleocapsid and Nsp3 binding: an in silico study [PDF]

Archives of Microbiology, 2020
Severe acute respiratory syndrome virus 2 (SARS-CoV-2) belongs to the single-stranded positive-sense RNA family. The virus contains a large genome that encodes four structural proteins, small envelope (E), matrix (M), nucleocapsid phosphoprotein (N), spike (S), and 16 nonstructural proteins (nsp1-16) that together, ensure replication of the virus in ...

SH3 domain-mediated recruitment of host cell amphiphysins by alphavirus nsP3 promotes viral RNA replication. [PDF]

PLoS Pathogens, 2011
Among the four non-structural proteins of alphaviruses the function of nsP3 is the least well understood. NsP3 is a component of the viral replication complex, and composed of a conserved aminoterminal macro domain implicated in viral RNA synthesis, and ...

Scalable Inhibitors of the Nsp3–Nsp4 Coupling in SARS-CoV-2

ACS Omega, 2023
The human Betacoronavirus SARS-CoV-2 is a novel pathogen claiming millions of lives and causing a global pandemic that has disrupted international healthcare systems, economies, and communities. The virus is fast mutating and presenting more infectious but less lethal versions. Currently, some small-molecule therapeutics have received FDA emergency use
