چکیده

Influenza virus endonuclease activity was studied in vitro with model virion RNA (vRNA) and cRNA molecules. We show that endonuclease activity can be partially rescued by transplanting vRNA-like promoter features into the model cRNA promoter. This study defines three distinctive features within the vRNA promoter--absent in the cRNA promoter--that are required for endonuclease cleavage.

An endonuclease switching mechanism in the virion RNA and cRNA promoters of Thogoto orthomyxovirus.

An in vitro assay was developed to investigate endonuclease activity of Thogoto virus, a tick-borne orthomyxovirus. Endonuclease activity relied on an interaction between the 3' and 5' termini of virion RNA (vRNA) and not those of cRNA. Evidence was obtained that cap structures are cleaved directly from cap donors and that cleavage does not occur after pyrimidines. A 5' hook structure, present ...

Interaction of the influenza a virus nucleocapsid protein with the viral RNA polymerase potentiates unprimed viral RNA replication.

The influenza A virus polymerase transcribes and replicates the eight virion RNA (vRNA) segments. Transcription is initiated with capped RNA primers excised from cellular pre-mRNAs by the intrinsic endonuclease of the viral polymerase. Viral RNA replication occurs in two steps: first a full-length copy of vRNA is made, termed cRNA, and then this cRNA is copied to produce vRNA. The synthesis of ...

The Effect of Herpes Simplex Virus Virion Host Shutoff Gene- a New Suicide Gene- on Tumor Cells

Background: The herpes simplex virus (HSV) UL41 gene product, virion host shutoff (Vhs) protein, mediates the rapid degradation of both viral and cellular mRNA. This ability suggests that Vhs protein can be used as a suicide gene in cancer gene therapy applications. The recent reports have shown that the degradation of cellular mRNA during herpes simplex infection is selective. RNA containing A...

Different de novo initiation strategies are used by influenza virus RNA polymerase on its cRNA and viral RNA promoters during viral RNA replication.

Various mechanisms are used by single-stranded RNA viruses to initiate and control their replication via the synthesis of replicative intermediates. In general, the same virus-encoded polymerase is responsible for both genome and antigenome strand synthesis from two different, although related promoters. Here we aimed to elucidate the mechanism of initiation of replication by influenza virus RN...

Amino acid residues in the N-terminal region of the PA subunit of influenza A virus RNA polymerase play a critical role in protein stability, endonuclease activity, cap binding, and virion RNA promoter binding.

The RNA-dependent RNA polymerase of influenza virus is a heterotrimer formed by the PB1, PB2, and PA subunits. Although PA is known to be required for polymerase activity, its precise role is still unclear. Here, we investigated the function of the N-terminal region of PA. Protease digestion of purified recombinant influenza virus A/PR/8/34 PA initially suggested that its N-terminal region is f...
