In order to increase our understanding of the assembly of the capsid proteins of AHSV, for the development of subunit vaccines and to study viral morphogenesis, it is necessary to investigate the interaction of the four major structural proteins of AHSV in the absence of other AHSV proteins and the viral genome. To investigate particle formation it was necessary to synthesise the proteins of in...

The Sindbis-group alphavirus S.A.AR86 encodes a threonine at nonstructural protein 1 (nsP1) 538 that is associated with neurovirulence in adult mice. Mutation of the nsP1 538 Thr to the consensus Ile found in nonneurovirulent Sindbis-group alphaviruses attenuates S.A.AR86 for adult mouse neurovirulence, while introduction of Thr at position 538 in a nonneurovirulent Sindbis virus background con...

Sindbis virus and Ross River virus are alphaviruses whose nonstructural proteins share 64% identity and whose structural proteins share 48% identity. Starting from full-length cDNA clones of both viruses, we have generated two reciprocal Sindbis-Ross River chimeric viruses in which the structural and nonstructural regions have been exchanged. These chimeric viruses replicate readily in several ...

OBJECTIVE To study the effects of hepatitis C virus gene nonstructural protein 2 on the expressions of Bcl-2 and Bax in liver hepatocellular cells. METHOD The study was conducted at the Department of Infectious Diseases, the First Affiliated Hospital of Medical School, Xi'an Jiaotong University, Xi'an, China, from March 2012 to April 2013. Negative controls pEGFP-C3-NS2, pEGFP-C3-C and pEGFP-...

BACKGROUND Replication and assembly of vertebrate reoviruses occur in specific intracellular compartments known as viral factories. Recently, NS88 and NS80, the nonstructural proteins from aquareoviruses, have been proposed to share common traits with µNS from orthoreoviruses, which are involved in the formation of viral factories. METHODOLOGY/PRINCIPAL FINDINGS In this study, the NS80 charac...

Diversity analysis of 71 published dengue virus gene sequences revealed several strains that appeared to be mosaics comprising gene regions with conflicting evolutionary histories. Subsequent maximum likelihood breakpoint estimation identified seven recombinants, including members of three of the four dengue virus serotypes, with breakpoints in the premembrane/membrane gene, the envelope gene, ...

background bovine viral diarrhea (bvd) is an economically important disease of cattle with a worldwide distribution. diagnosis of bvd relies on laboratory-based detections of its viral causing agent or virus specific antibodies. the most common laboratory method used for this purpose is the elisa. bovine viral diarrhea virus (bvdv) nonstructural protein 3 (ns3) is one of the most highly conserv...

conclusions overall, results of present study were consistent with the data reported earlier base on 5’ ntr in iranian isolates and revealed genotype ir2 is major genotype in iranian hgv-positive patient. it means there are higher similarities between iranian and europe-usa in hgv ns3 gene. results nucleotide blast results emphasized that most similar sequences to ir ns3 sequences were those fr...
