Messenger activity of virion RNA for avian leukosis viral envelope glycoprotein.
An intracellular assay for viral envelope glycoprotein (env) messenger was employed to analyze the RNA from virus particles of Rous-associated virus type 2. For this assay RNA was microinjected into cells infected by the env-deficient Bryan strain of Rous sarcoma virus [RSV(-) cells]. Only when the injected RNA could be translated by the recipient cells to produce viral envelope glycoprotein wa...
متن کاملDirect evidence for messenger activity of influenza virion RNA.
In a cell-free system of Escherichia coli, RNA from influenza virus particles is translated into a polypeptide antigenically identical with the ribonucleoprotein and several more proteins, some of which correspond in size to viral structural components.
متن کاملRadioimmunoassay for the envelope glycoprotein of subgroup E avian leukosis-sarcoma viruses.
In the absence of infectious subgroup E avian leukosis-sarcoma (ALS) viruses, some chicken embryo cells contain in their cell membrane the envelope glycoprotein of subgroup E viruses (gpE) (Hanafusa et al. 1973). The partial expression of subgroup E virus was first recognized as chick-cell-associated helper factor (chfl, which provided the helper function for the envelope-defective Bryan high-t...
متن کاملGeneration and evaluation of avian leukosis virus subgroup J envelope glycoprotein recombinant pseudovirions.
Retroviral and lentiviral vector pseudotypes (based on human immunodeficiency virus type 1, HIV-1) have been used for stable and safe gene transfer because of their broad host ranges and high mechanical strength. In the present study, a recombinant avian leukosis virus subgroup J (ALV-J) polypeptide pseudotyped with lentivirus membrane glycoproteins gp85 and gp37, HIV/env-ALV, was generated, ch...
متن کاملCritical role for the cysteines flanking the internal fusion peptide of avian sarcoma/leukosis virus envelope glycoprotein.
The transmembrane subunit (TM) of the envelope glycoprotein (Env) of the oncovirus avian sarcoma/leukosis virus (ASLV) contains an internal fusion peptide flanked by two cysteines (C9 and C45). These cysteines, as well as an analogous pair in the Ebola virus GP glycoprotein, are predicted to be joined by a disulfide bond. To examine the importance of these cysteines, we mutated C9 and C45 in th...
