Mutational analysis of the virion host shutoff gene (UL41) of herpes simplex virus (HSV): characterization of HSV type 1 (HSV-1)/HSV-2 chimeras.
During lytic herpes simplex virus (HSV) infections, the half-lives of host and viral mRNAs are regulated by the HSV virion host shutoff (Vhs) protein (UL41). The sequences of the UL41 polypeptides of HSV type 1 (HSV-1) strain KOS and HSV-2 strain 333 are 87% identical. In spite of this similarity, HSV-2 strains generally shut off the host more rapidly and completely than HSV-1 strains. To exami...
متن کاملSite-directed mutagenesis of the virion host shutoff gene (UL41) of herpes simplex virus (HSV): analysis of functional differences between HSV type 1 (HSV-1) and HSV-2 alleles.
During lytic herpes simplex virus (HSV) infections, the HSV virion host shutoff protein (UL41) accelerates the turnover of host and viral mRNAs. Although the UL41 polypeptides from HSV type 1 (HSV-1) strain KOS and HSV-2 strain 333 are 87% identical, HSV-2 strains generally shut off the host more rapidly and completely than HSV-1 strains. In a previous study, we identified three regions of the ...
متن کاملExpression and in vitro Characterization of Herpes Simplex Virus 1 (HSV-1) ORF P Protein
Herpes simplex virus 1 (HSV-1) unspliced 8.3 latency associated transcript (LAT), which located in the long repeat sequences, has been shown to contain at least 16 open reading frames (ORF: A-P). One of these ORF, ORF P, maps almost entirely antisense to HSV-1 neurovirulence gene, ICP34.5. Both ORF P and ICP34.5 are located in the long repeat and are antisense overlapping genes. Therefore, in O...
متن کاملSeroepidemiological Study of Herpes Simplex Virus Type 2 (HSV-2) Antibody in Shiraz, Iran
Background: Herpes Simplex Virus (HSV) Type 2 is a widespread human infectious agent responsible for persistent and latent infections. Objectives: To estimate the regional seroprevalence of anti HSV-2 antibody in Shiraz, Iran and to investigate the possible correlation of seropositivity with malignant changes in subjects’ Papanicolaou (Pap) tests. Methods: Data were collected in a cross-section...
متن کاملThe latency-associated gene of herpes simplex virus type 1 (HSV-1) interferes with superinfection by HSV-1.
During herpes simplex virus type 1 (HSV-1) lifelong latency in human peripheral sensory ganglia (PSG), only the viral latency-associated transcript (LAT) gene is expressed. This raises the possibility that this gene is involved in establishment of latency of the virus, its maintenance, or reactivation. Here we present data that indicate yet another independent function of the LAT gene: interfer...
