Structural proteins of rabies virus.

چکیده
Purified rabies virions, unlabeled or labeled with radioactive amino acids or d-glucosamine, were dissociated into their polypeptides by treatment with sodium dodecyl sulfate in a reducing environment and fractionated by electroiphoresis in sodium dodecyl sulfate-containing polyacrylamide gel. The molecular weights of individual polypeptides were estimated by comparison of their rate of migration with that of protein markers of known molecular weight. Purified viral nucleocapsid and a mixture of envelope components, isolated from virions disrupted by sodium deoxycholate, were analyzed by the same procedure. The number of molecules per virion of each polypeptide was estimated from the proportions of the separated components, the known molecular weight of the viral ribonucleic acid, and the chemical composition of the nucleocapsid. The protein moiety of the nucleocapsid particle was estimated to consist of 1,713 molecules of a major polypeptide (molecular weight, 62,000 daltons) and 76 molecules of a minor polypeptide (molecular weight, 55,000 daltons). In addition to 1,783 molecules of a glycoprotein component (molecular weight, 80,000 daltons), the viral envelope contains 789 and 1,661 molecules, respectively, of two other polypeptides (molecular weight, 40,000 and 25,000 daltons).

Cloning and expression of fragment of the rabies virus nucleoprotein gene in Escherichia coli and evaluation of antigenicity of the expression product
Rabies virus nucleoprotein (N protein) encapsidates genomic RNA of the virus and forms the viral ribonucleoprotein complex. These N proteins represent highly organized structures which activate proliferation of B cells and production antibodies against the N protein. In addition to the B cell, the rabies virus N protein has been shown to induce potent T helper cell responses resulting in a long...
متن کاملProkaryotic Expression, Purification, and Polyclonal Antibody Production of a Truncated Recombinant Rabies Virus L Protein
Background: Rabies virus (RABV) is a deadly neurotropic virus that causes the disease of rabies in humans and animals. L protein is one of the large structural protein of rabies virus, which displays multiple enzymatic activities, and is required for viral transcription and replication. Objectives: A truncated L protein of Rabies virus is being cloned, expressed and purified to produce relevant...
متن کاملStructure-function relationships and mode of replication of animal rhabdoviruses.
Recently accumulated knowledge allows more precise comparison of the structural (and possibly evolutionary) relationships of several different animal rhabdoviruses: vesicular stomatitis virus, rabies virus, Kern Canyon virus, and spring viremia of carp virus. Each virus is composed primarily of a glycoprotein, an RNA-associated nucleoprotein, and one or two membrane proteins. Vesicular stomatit...
متن کاملInduction and biological properties of defective interfering particles of rabies virus.
A method for obtaining large quantities of defective interfering (DI) rabies virus particles that fulfill all the criteria delineated by Huang and Baltimore (1970) is described. The purified rabies DI virion was found to be much shorter (60 to 80 nm) than the complete virion (180 nm) and to have a viral genome of about half the size of normal rabies RNA but with all of the structural proteins o...

Background: Rabies virus is a neurotropic virus that causes fatal, but, a preventable disease in mammals. Administration of rabies immunoglobulin (RIG) is essential for the post-exposure of the prophylaxis to prevent the disease. However, replacement of polyclonal RIGs with alternative monoclonal antibodies (MAbs) that are capable of neutralizing rabies virus has been recommend...
متن کاملA Study on the Ocular Infection with Rabies Virus in Mouse
Introduction: The most common mode of rabies virus transmission is through a bite wound or contact of broken skin with saliva of a rabid animal. Various other routes of virus transmission include exposure of mucous membranes (i.e. eyes, nose, and mouth) to infected saliva of a rabid animal, aerosol transmission, and corneal transplantation. Laboratory workers during work with rabies virus and v...
