The murine coronavirus nucleocapsid gene is a determinant of virulence.
The murine coronavirus, mouse hepatitis virus (MHV) strain A59, causes acute encephalitis and chronic demyelinating disease as well as hepatitis in mice. The JHM strain (also called MHV-4 or JHM.SD) causes fatal encephalitis and only minimal hepatitis. Previous analysis of chimeric recombinant MHVs in which the spike gene, encoding the protein that mediates viral entry and cell-to-cell fusion, ...
متن کاملThe nucleocapsid protein gene of bovine coronavirus is bicistronic.
For animal RNA viruses that replicate through an RNA intermediate, reported examples of bicistronic mRNAs with overlapping open reading frames in which one cistron is contained entirely within another have been made only for those with negative-strand or double-stranded genomes. In this report, we demonstrate for the positive-strand bovine coronavirus that an overlapping open reading frame pote...
متن کاملThe Coronavirus Nucleocapsid Is a Multifunctional Protein
The coronavirus nucleocapsid (N) is a structural protein that forms complexes with genomic RNA, interacts with the viral membrane protein during virion assembly and plays a critical role in enhancing the efficiency of virus transcription and assembly. Recent studies have confirmed that N is a multifunctional protein. The aim of this review is to highlight the properties and functions of the N p...
متن کاملAn Innate Immunity-Regulating Virulence Determinant Is Uniquely Encoded within the Andes Virus Nucleocapsid Protein
UNLABELLED Andes virus (ANDV) is the only hantavirus known to spread from person to person and shown to cause highly lethal hantavirus pulmonary syndrome (HPS) in patients and Syrian hamsters. Hantaviruses replicate in human endothelial cells and accomplish this by restricting the early induction of beta interferon (IFN-β)- and IFN-stimulated genes (ISGs). Our studies reveal that the ANDV nucle...
متن کاملThe Replicase Gene of Avian Coronavirus Infectious Bronchitis Virus Is a Determinant of Pathogenicity
We have previously demonstrated that the replacement of the S gene from an avirulent strain (Beaudette) of infectious bronchitis virus (IBV) with an S gene from a virulent strain (M41) resulted in a recombinant virus (BeauR-M41(S)) with the in vitro cell tropism of the virulent virus but that was still avirulent. In order to investigate whether any of the other structural or accessory genes pla...
