Identification of mosquito proteins that differentially interact with alphavirus nonstructural protein 3, a determinant of vector specificity.

PLoS Neglected Tropical Diseases, 2023
Chikungunya virus (CHIKV) and the closely related onyong-nyong virus (ONNV) are arthritogenic arboviruses that have caused significant, often debilitating, disease in millions of people.

Mosquito Rasputin interacts with chikungunya virus nsP3 and determines the infection rate in Aedes albopictus

Parasites & Vectors, 2015
Background Chikungunya virus (CHIKV) is an arthritogenic alphavirus (family Togaviridae), transmitted by Aedes species mosquitoes. CHIKV re-emerged in 2004 with multiple outbreaks worldwide and recently reached the Americas where it has infected over a ...

Combined structural, biochemical and cellular evidence demonstrates that both FGDF motifs in alphavirus nsP3 are required for efficient replication [PDF]

Open Biology, 2016
Recent findings have highlighted the role of the Old World alphavirus non-structural protein 3 (nsP3) as a host defence modulator that functions by disrupting stress granules, subcellular phase-dense RNA/protein structures formed upon environmental ...

Discovery of Drug-like Ligands for the Mac1 Domain of SARS-CoV-2 Nsp3 [PDF]

SLAS Discovery, 2020
ABSTRACTSmall molecules that bind the SARS-CoV-2 non-structural protein 3 Mac1 domain in place of ADP-ribose could be useful as molecular probes or scaffolds for COVID-19 antiviral drug discovery because Mac1 has been linked to coronavirus’ ability to evade cellular detection. A high-throughput assay based on differential scanning fluorimetry (DSF) was

WHOLE GENOME SEQUENCE OF SARS-COV-2 FROM COVID-19 ACQUIRED HEMOPHILIA PATIENT

International Journal of Infectious Diseases, 2023
Intro: Acquired hemophilia is an atypical pathology of SARS-CoV-2 infection, which could be variant associated. Here, we share a sequence of the SARS-CoV-2 genome from patient with COVID-19 acquired haemophilia.

Rotavirus NSP3 Is a Translational Surrogate of the Poly(A) Binding Protein-Poly(A) Complex [PDF]

Journal of Virology, 2015
ABSTRACT Through its interaction with the 5′ translation initiation factor eIF4G, poly(A) binding protein (PABP) facilitates the translation of 5′-capped and 3′-poly(A)-tailed mRNAs. Rotavirus mRNAs are capped but not polyadenylated, instead terminating in a 3′ GACC motif that is recognized by the viral protein NSP3, which competes with PABP ...

Phosphorylation Sites in the Hypervariable Domain in Chikungunya Virus nsP3 Are Crucial for Viral Replication [PDF]

Journal of Virology, 2021
CHIKV outbreaks have affected millions of people, creating a need for the development of antiviral approaches. nsP3 is a component of the CHIKV RNA replicase and is involved in interactions with host proteins and signaling cascades. Phosphorylation of the HVD in nsP3 is important for the virulent alphavirus phenotype.

Predicted binding interface between coronavirus nsp3 and nsp4 [PDF]

, 2022
AbstractDouble membrane vesicles (DMVs) in coronavirus-infected cells feature pores that span both membranes. DMV pores were observed to have six-fold symmetry and include the nsp3 protein. Co-expression of SARS-CoV nsp3 and nsp4 induces DMV formation, and elements of nsp3 and nsp4 have been identified that are essential for membrane disruption.

Discovery of in silico hits targeting the nsP3 macro domain of chikungunya virus [PDF]

Journal of Molecular Modeling, 2014
The recent emergence and re-emergence of alphaviruses, in particular the chikungunya virus (CHIKV), in numerous countries has invoked a worldwide threat to human health, while simultaneously generating an economic burden on affected countries. There are currently no vaccines or effective drugs available for the treatment of the CHIKV, and with few lead
