The nsp3 Macrodomain Promotes Virulence in Mice with Coronavirus-Induced Encephalitis [PDF]
ABSTRACT All coronaviruses encode a macrodomain containing ADP-ribose-1″-phosphatase (ADRP) activity within the N terminus of nonstructural protein 3 (nsp3). Previous work showed that mouse hepatitis virus strain A59 (MHV-A59) with a mutated catalytic site (N1348A) replicated similarly to wild-type virus but was unable to cause ...

Rotavirus Nonstructural Protein NSP3 Is Not Required for Viral Protein Synthesis [PDF]
ABSTRACT Initiation is the rate-limiting step in protein synthesis and therefore an important target for regulation. For the initiation of translation of most cellular mRNAs, the cap structure at the 5′ end is bound by the translation factor eukaryotic initiation factor 4E (eIF4E), while the poly(A) tail, at the 3′ end, is recognized by the ...

Crystal structures of SARS-CoV-2 ADP-ribose phosphatase: from the apo form to ligand complexes
Among 15 nonstructural proteins (Nsps), the newly emerging Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2) encodes a large, multidomain Nsp3. One of its units is the ADP-ribose phosphatase domain (ADRP; also known as the macrodomain, MacroD),

Recognition of eIF4G by Rotavirus NSP3 Reveals a Basis for mRNA Circularization [PDF]
Rotaviruses, segmented double-stranded RNA viruses, co-opt the eukaryotic translation machinery with the aid of nonstructural protein 3 (NSP3), a rotaviral functional homolog of the cellular poly(A) binding protein (PABP). NSP3 binds to viral mRNA 3' consensus sequences and circularizes mRNA via interactions with eIF4G.

Of the 16 non-structural proteins (Nsps) encoded by SARS CoV-2, Nsp3 is the largest and plays important roles in the viral life cycle. Being a large, multidomain, transmembrane protein, Nsp3 has been the most challenging Nsp to characterize.

Crystal structure of the CoV-Y domain of SARS-CoV-2 nonstructural protein 3
Replication of the coronavirus genome starts with the formation of viral RNA-containing double-membrane vesicles (DMV) following viral entry into the host cell.

Structure of the X (ADRP) domain of nsp3 from feline coronavirus [PDF]
The structure of the X (or ADRP) domain of a pathogenic variant of feline coronavirus (FCoV) has been determined in tetragonal and cubic crystal forms to 3.1 and 2.2 A resolution, respectively. In the tetragonal crystal form, glycerol-3-phosphate was observed in the ADP-ribose-binding site.

Recognition of the Rotavirus mRNA 3′ Consensus by an Asymmetric NSP3 Homodimer [PDF]
Rotaviruses, the cause of life-threatening diarrhea in humans and cattle, utilize a functional homolog of poly(A) binding protein (PABP) known as nonstructural protein 3 (NSP3) for translation of viral mRNAs. NSP3 binds to viral mRNA 3' consensus sequences and circularizes the mRNA via interactions with eIF4G.

Alphaviruses infect a diverse range of host organisms including mosquitoes, mammals, and birds. The enigmatic alphavirus non-structural protein 3 (nsP3) has an intrinsically disordered, C-terminal hypervariable domain (HVD) that can interact with a ...
