Functional and physical interactions of the herpes simplex virus type 1 UL20 membrane protein with glycoprotein K.

Construction of an Eukaryotic Expression Vector Encoding Herpes Simplex Virus Type 2 Glycoprotein D and In Vitro Expression of the Desired Protein

To construct of an eukaryotic expression vector encoding herpes simplex virus type 2 (HSV-2) glycoprotein D (gD2), an Iranian isolate of HSV-2 was propagated in HeLa cell line and its DNA was extracted and used as template in polymerase chain reactions (PCR), to amplify gD2 gene. Primers were designed and the restriction enzyme sites for EcoRI and XhoI were considered at their 5′ ends respectiv...

Expression of the Herpes Simplex Virus Type 2 Glycoprotein D in Baculovirus Expression System and Evaluation of Its Immunogenicity in Guinea Pigs

Background: Herpes simplex virus type 2 (HSV-2) is highly prevalent and major cause of genital herpes in humans. The life-long nature of infection and the increasing prevalence of genital herpes imply that vaccination is the best strategy for controlling the spread of infection and limiting HSV disease. HSV glycoprotein D (gD) is one of the most important viral immunogen which has an essential ...

Immunogenicity and Efficacy of Baculovirus Derived Glycoprotein D of Herpes Simplex Virus Type-I in Mice

The UL20 gene product of pseudorabies virus functions in virus egress.

The UL20 open reading frame is positionally conserved in different alphaherpesvirus genomes and is predicted to encode an integral membrane protein. A previously described UL20- mutant of herpes simplex virus type 1 (HSV-1) exhibited a defect in egress correlating with retention of virions in the perinuclear space (J. D. Baines, P. L. Ward, G. Campadelli-Fiume, and B. Roizman, J. Virol. 65:6414...

Plasma membrane topology of syncytial domains of herpes simplex virus type 1 glycoprotein K (gK): the UL20 protein enables cell surface localization of gK but not gK-mediated cell-to-cell fusion.

Most spontaneously occurring mutations that cause extensive herpes simplex virus type 1 (HSV-1)-induced cell fusion are single amino acid changes within glycoprotein K (gK). Despite the strong genetic association of gK with virus-induced cell fusion, its direct involvement in cellular membrane fusion has been controversial, largely due to previously unsuccessful efforts to detect gK expression ...
