Production of Recombinant Snakehead Rhabdovirus: the NV Protein Is Not Required for Viral Replication†

Johnson, Marc C., Simon, Benjamin E., Kim, Carol H., Leong, Jo-Ann C.

Snakehead rhabdovirus (SHRV) affects warm water fish in Southeast Asia and belongs to the genus Novirhabdovirus by virtue of its nonvirion gene (NV). Because SHRV grows best at temperatures between...

Kim, Carol H., Johnson, Marc C., Drennan, John D., Simon, Benjamin E., Thomann, Estela, Leong, Jo-Ann C.

Protective immunity by vaccination with plasmid DNA encoding a viral glycoprotein (G) has long been assumed to result from the induction of a specific immune response. We report here that the initial...

PR Domain of Rous Sarcoma Virus Gag Causes an Assembly/Budding Defect in Insect Cells

Johnson, Marc C., Scobie, Heather M., Vogt, Volker M.

While baculovirus expression of Gag proteins from numerous retroviruses has led reliably to production of virus-like particles (VLPs), we observed that expression of Rous sarcoma virus Gag failed to...

Nucleic Acid-Independent Retrovirus Assembly Can Be Driven by Dimerization

Johnson, Marc C., Scobie, Heather M., Ma, Yu May, Vogt*, Volker M.

The Gag protein of retroviruses alone can polymerize into regular virus-like particles (VLPs) both in vitro and in vivo. In most circumstances the capsid (CA) and nucleocapsid (NC) domains of Gag as...

The NV Gene of Snakehead Rhabdovirus (SHRV) Is Not Required for Pathogenesis, and a Heterologous Glycoprotein Can Be Incorporated into the SHRV Envelope

Alonso, Marta, Kim, Carol H., Johnson, Marc C., Pressley, Meagan, Leong, Jo-Ann

Snakehead rhabdovirus (SHRV) affects warm-water fish in Southeast Asia and belongs to the genus Novirhabdovirus by virtue of its “nonvirion” (NV) gene. To examine the function of the NV gene, we...

The C-Terminal Half of TSG101 Blocks Rous Sarcoma Virus Budding and Sequesters Gag into Unique Nonendosomal Structures†

Johnson, Marc C., Spidel, Jared L., Ako-Adjei, Danso, Wills, John W., Vogt, Volker M.

Retroviral late domains (L domains) are short amino acid sequences in the Gag protein that facilitate the process of budding. L domains act by recruiting the ESCRT complexes, which normally function...

The Retroviral Capsid Domain Dictates Virion Size, Morphology, and Coassembly of Gag into Virus-Like Particles

Ako-Adjei, Danso, Johnson, Marc C., Vogt, Volker M.

The retroviral structural protein, Gag, is capable of independently assembling into virus-like particles (VLPs) in living cells and in vitro. Immature VLPs of human immunodeficiency virus type 1...

Visualization of retrovirus budding with correlated light and electron microscopy

Larson, Daniel R., Johnson, Marc C., Webb, Watt W., Vogt, Volker M.

We have used correlated scanning EM (SEM) and multiphoton fluorescence microscopy to visualize budding of virus-like particles (VLPs) of Rous sarcoma virus (RSV) and HIV type 1 (HIV-1). When the Gag...
