Both a DNA-binding domain and a Vp1 interactive determinant have been mapped to the carboxy-terminal 40 residues of the simian virus 40 (SV40) minor capsid proteins, Vp2 and Vp3 (Vp2/3), with the last 13 residues being necessary for these activities. The role of this DNA-binding domain in SV40 morphogenesis and the ability to separate these two signals were investigated by mutagenesis and asses...
زمینه و هدف: اهمیت پروتئین vp2 پاروویروس سگی در اتصال به سلولهای سرطانی انسانی و کیتهای تشخیصی دامپزشکی سبب شده تا مطالعات گستردهای در زمینه تولید این پروتئین صورت گیرد. هدف از انجام این پژوهش کلونینگ و تایید بیان پروتئین پوششی vp2 پاروویروس سگی در سیستم پروکاریوتی و بهینه نمودن بیان پروتئین vp2 در سیستم منحصر به فرد پروکاریوتی بدون سلول میباشد. مواد و روشها: در این مطالعه تجربی، پلاسمید p...
246 Abstract Infectious bursal disease (IBD) is an economically important viral disease of chickens with worldwide distribution which suppresses the immune system of young chickens. VP2 is the major host-protective protein of infectious bursal disease virus (IBDV). The encoding region of VP2 protein was PCR amplified from a plasmid containing a cDNA fragment of large genomic segment of IBDV, st...
Partial amino-terminal sequence analysis was performed on radiolabeled polio-virus capsid proteins VP1, VP2, and VP3. A computer-assisted comparison of the amino acid sequences obtained with that predicted by the nucleotide sequence of the poliovirus genome allows assignment of the amino terminus of each capsid protein to a unique position within the virus polyprotein. Sequence analysis of tryp...
BACKGROUND: Canine Parvovirus (CPV) is one of the major causes of fatal gastroenteritis in young dogs. After emergence of CPV-2, two new variants were reported and named CPV-2a and CPV-2b. In 2001 the newest variant was reported and named CPV-2c. The difference between CPV strains is related to amino acid changes in viral capsid protein (VP2). OBJECTIVES: The aim of the present study was geneti...
African horsesickness (AHS) is a devastating disease of horses. The disease is caused by the double-stranded RNA-containing African horsesickness virus (AHSV). Using electron cryomicroscopy and three-dimensional image reconstruction, we determined the architecture of an AHSV serotype 4 (AHSV-4) reference strain. The structure revealed triple-layered AHS virions enclosing the segmented genome an...
Infectious bursal disease virus (IBDV) is a birnavirus that causes a highly contagious immunosuppressive disease in young chickens. The capsid protein VP2 of IBDV plays multiple roles in its life cycle. To more comprehensively understand the functions of VP2 involved in the communication between virus and host, we used yeast two-hybrid screening to identify the cellular factors that interact wi...
Analysis and phylogenetic comparisons of full-length VP2 genes of the 24 bluetongue virus serotypes.
The outer capsid protein VP2 of Bluetongue virus (BTV) is a target for the protective immune response generated by the mammalian host. VP2 contains the majority of epitopes that are recognized by neutralizing antibodies and is therefore also the primary determinant of BTV serotype. Full-length cDNA copies of genome segment 2 (Seg-2, which encodes VP2) from the reference strains of each of the 2...
An important question in neuropathology involves determining the antigens that are targeted during demyelinating disease. Viral infection of the central nervous system (CNS) leads to T-cell responses that can be protective as well as pathogenic. In the Theiler's murine encephalomyelitis virus (TMEV) model of demyelination it is known that the immune response to the viral capsid protein 2 (VP2) ...
