Processing of pseudorabies virus glycoprotein gII

Pseudorabies virus glycoprotein M inhibits membrane fusion.

A transient transfection-fusion assay was established to investigate membrane fusion mediated by pseudorabies virus (PrV) glycoproteins. Plasmids expressing PrV glycoproteins under control of the immediate-early 1 promoter-enhancer of human cytomegalovirus were transfected into rabbit kidney cells, and the extent of cell fusion was quantitated 27 to 42 h after transfection. Cotransfection of pl...

Pseudorabies Virus Glycoprotein B Can Be Used

Pseudorabies virus displays variable numbers of a repeat unit adjacent to the 3' end of the glycoprotein gII gene.

The coding region of the glycoprotein complex gII of pseudorabies virus (PRV) is located in the unique long part of the genome on SalI subfragments 1A and 1G of BamHI fragment 1 (map units 0.105 to 0.130). Fragment 1G which includes the 3' end of the gII gene displays a size heterogeneity among different PRV strains and also within plaque isolates of a given strain. To reveal the cause of this ...

Adaptability in herpesviruses: glycoprotein D-independent infectivity of pseudorabies virus.

Initial contact between herpesviruses and host cells is mediated by virion envelope glycoproteins which bind to cellular receptors. In several alphaherpesviruses, the nonessential glycoprotein gC has been found to interact with cell surface proteoglycans, whereas the essential glycoprotein gD is involved in stable secondary attachment. In addition, gD is necessary for penetration, which involve...

Virion-incorporated glycoprotein B mediates transneuronal spread of pseudorabies virus.

Transneuronal spread of pseudorabies virus (PRV) is a multistep process that requires several virally encoded proteins. Previous studies have shown that PRV glycoprotein B (gB), a component of the viral fusion machinery, is required for the transmission of infection to postsynaptic, second-order neurons. We sought to identify the gB-mediated step in viral transmission. We determined that gB is ...
