Recombinant virus-like particles (VLPs) represent a promising tool for protein engineering. Recently, trichodysplasia spinulosa-associated polyomavirus (TSPyV) viral protein 1 (VP1) was efficiently produced in yeast expression system and shown to self-assemble to VLPs. In the current study, TSPyV VP1 protein was exploited as a carrier for construction of chimeric VLPs harboring selected B and T...
The polyomavirus coat protein viral protein 1 (VP1) has the intrinsic ability to self-assemble in vitro into polymorphic capsid-like structures on addition of calcium. In contrast, polyomavirus assembly in vivo is rigorously controlled, such that virions of uniform size are formed only in the cell nucleus. During viral infection, the 72 kDa cellular chaperone heat shock cognate protein (hsc70) ...
The Karolinska Institutet and Washington University polyomaviruses (KIPyV and WUPyV, respectively) are recently discovered human viruses that infect the respiratory tract. Although they have not yet been linked to disease, they are prevalent in populations worldwide, with initial infection occurring in early childhood. Polyomavirus capsids consist of 72 pentamers of the major capsid protein vir...
BACKGROUND Human Enterovirus 71 (EV71) is a common cause of hand, foot and mouth disease (HFMD) in young children. It is often associated with severe neurological diseases and has caused high mortalities in recent outbreaks across the Asia Pacific region. Currently, there is no effective vaccine and antiviral agents available against EV71 infections. VP1 is one of the major immunogenic capsid p...
BACKGROUND Viral protein-1 (VP1) is a major capsid protein of Coxsakievirus B3 (CVB3) that plays an important role in directing viruses towards permissive cells and acts as a main antigenic site of the virus in eliciting of host immune response, hence it seems VP1 can be considered as a vaccine candidate against CVB3 infection. In this study, cDNA of VP1 was prepared, cloned into pET expression...
ویروس کم خونی عفونی، عامل بیماری بالینی کم خونی عفونی و یکی از عوامل ایمونوسوپرسیو در ماکیان می باشد. در این بررسی بافت های طحال، کبد و تیموس نمونه های درمانگاهی و کشتارگاهی جوجه گوشتی خراسان بزرگ، با هدف مطالعه تنوع ژنتیکی ژن های vp1، vp2 و vp3 این ویروس، به روش pcr غربال گری شدند. از میان نمونه های مثبت تعداد 20 نمونه با دو جفت پرایمر اختصاصی در برگیرنده بخش اصلی ناحیه رمز کننده vp1 و تمام نا...
A 2.3-kb cDNA clone encoding Aleutian mink disease parvovirus (ADV) structural proteins VP1 and VP2 was inserted into the polyhedron gene of Autographa californica nuclear polyhedrosis virus (AcNPV) and expressed by the recombinant virus, AcADV-1, in Spodoptera frugiperda-9 cells. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis and western immunoblot analysis (WIA) indicated that synt...
Maize (Zea mays) Viviparous1 (VP1) and Arabidopsis ABI3 are orthologous transcription factors that regulate key aspects of plant seed development and ABA signaling. To understand VP1-regulated gene expression on a global scale, we have performed oligomicroarray analysis of transgenic Arabidopsis carrying 35S::VP1 in an abi3 null mutant background. We have identified 353 VP1/ABA-regulated genes ...
Hepatitis A virus (HAV) encodes a single polyprotein which is posttranslationally processed into the functional structural and nonstructural proteins. Only one protease, viral protease 3C, has been implicated in the nine protein scissions. Processing of the capsid protein precursor region generates a unique intermediate, PX (VP1-2A), which accumulates in infected cells and is assumed to serve a...
Infectious bursal disease virus (IBDV) is a double-stranded RNA (dsRNA) virus of the Birnaviridae family. Its two genome segments are encapsidated together with multiple copies of the viral RNA-dependent RNA polymerase, VP1, in a single-shell capsid that is composed of VP2 and VP3. In this study we identified the domains responsible for the interaction between VP3 and VP1. Using the yeast two-h...
