Specific binding of host cellular proteins to multiple sites within the 3' end of mouse hepatitis virus genomic RNA.

The initial step in mouse hepatitis virus (MHV) RNA replication is the synthesis of negative-strand RNA from a positive-strand genomic RNA template. Our approach to begin studying MHV RNA replication is to identify the cis-acting signals for RNA synthesis and the proteins which recognize these signals at the 3' end of genomic RNA of MHV. To determine whether host cellular and/or viral proteins ...

Cellular proteins bind to the 3' end of Sindbis virus minus-strand RNA.

Forty-four nucleotides at the 5' terminus of the genomic RNA of Sindbis virus can form a stable stem-loop structure and have been shown previously to be important for viral replication. The structure formed by the complement of this sequence at the 3' end of the minus-strand RNA has been proposed to be a promoter for RNA replication and as such might be bound in a specific fashion by proteins o...

Norwalk virus RNA is infectious in mammalian cells.

Human noroviruses are positive-sense RNA viruses and are the leading cause of epidemic acute viral gastroenteritis in developed countries. The absence of an in vitro cell culture model for human norovirus infection has limited the development of effective antivirals and vaccines. Human histo-blood group antigens have been regarded as receptors for norovirus infection, and expression of the alph...

Translation and replication of hepatitis C virus genomic RNA depends on ancient cellular proteins that control mRNA fates.

Inevitably, viruses depend on host factors for their multiplication. Here, we show that hepatitis C virus (HCV) RNA translation and replication depends on Rck/p54, LSm1, and PatL1, which regulate the fate of cellular mRNAs from translation to degradation in the 5'-3'-deadenylation-dependent mRNA decay pathway. The requirement of these proteins for efficient HCV RNA translation was linked to the...

The IFITM Proteins Mediate Cellular Resistance to Influenza A H1N1 Virus, West Nile Virus, and Dengue Virus

Influenza viruses exploit host cell machinery to replicate, resulting in epidemics of respiratory illness. In turn, the host expresses antiviral restriction factors to defend against infection. To find host cell modifiers of influenza A H1N1 viral infection, we used a functional genomic screen and identified over 120 influenza A virus-dependency factors with roles in endosomal acidification, ve...
