Extracellular self-assembly of virus-like particles from secreted recombinant polyoma virus major coat protein.
Mouse polyoma virus major coat protein (VP1) expressed from a recombinant baculovirus is efficiently transported to infected cell nuclei and assembles into protein nanospheres morphologically similar to natural capsids. The nanospheres readily combine with plasmid DNA to form a hybrid gene therapy agent known as virus-like particles (VLPs). To facilitate large-scale production of VLPs free from...
متن کاملexpression of cucumber mosaic virus coat protein and its assembly into virus like particles
background cucumber mosaic virus (cmv) has isometric particles with a diameter of about 28–29 nm. a useful method to recognize regions from mutagenesis in the coat protein (cp) gene are important for particle assembly and the expression of viral in cp expression systems like bacteria such as e.coli or yeast as well as their assembly into virus-like particles (vlp). objectives in this paper, we ...
متن کاملConjugation of an antibody Fv fragment to a virus coat protein: cell-specific targeting of recombinant polyoma-virus-like particles.
The development of cell-type-specific delivery systems is highly desirable for gene-therapeutic applications. Current virus-based vector systems show broad cell specificity, which results in the need to restrict the natural tropism of these viral systems. Here we demonstrate that tumour-cell-specific virus-like particles can be functionally assembled in vitro from recombinant viral coat protein...
متن کاملAssembly of recombinant coat protein of sugarcane streak mosaic virus into potyvirus-like particles.
Coat protein (CP) gene of sugarcane streak mosaic virus-AP isolate (SCSMV-AP) was expressed in E. coli and recombinant CP (SCSMV-AP rCP) was purified by linear sucrose density gradient centrifugation. Observation of purified SCSMV-AP rCP under electron microscope revealed the presence of potyvirus-like particles (PVLPs). The assembled particles were shown to encapsidate CP gene transcripts by s...
متن کاملSelf-assembly of nucleocapsid-like particles from recombinant hepatitis C virus core protein.
Little is known about the assembly pathway and structure of hepatitis C virus (HCV) since insufficient quantities of purified virus are available for detailed biophysical and structural studies. Here, we show that bacterially expressed HCV core proteins can efficiently self-assemble in vitro into nucleocapsid-like particles. These particles have a regular, spherical morphology with a modal dist...
