Disulfide linkage and structure of highly stable yeast-derived virus-like particles of murine polyomavirus.
VP1 is the major coat protein of murine polyomavirus and forms virus-like particles (VLPs) in vitro. VLPs consist of 72 pentameric VP1 subunits held together by a terminal clamp structure that is further stabilized by disulfide bonds and chelation of calcium ions. Yeast-derived VLPs (yVLPs) assemble intracellularly in vivo during recombinant protein production. These in vivo assembled yVLPs dif...
متن کاملT-helper Cell-Mediated Proliferation and Cytokine Responses against Recombinant Merkel Cell Polyomavirus-Like Particles
The newly discovered Merkel Cell Polyomavirus (MCPyV) resides in approximately 80% of Merkel cell carcinomas (MCC). Causal role of MCPyV for this rare and aggressive skin cancer is suggested by monoclonal integration and truncation of large T (LT) viral antigen in MCC cells. The mutated MCPyV has recently been found in highly purified leukemic cells from patients with chronic lymphocytic leukem...
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 کاملAn equilibrium assembly model applied to Murine Polyomavirus
In Keef et al., Assembly Models for Papovaviridae based on Tiling Theory (submitted to J. Phys. Biol.), 2005 [1] we extended an equilibrium assembly model to the ðpseudo ÞT 1⁄4 7 viral capsids in the family of Papovaviridae providing assembly pathways for the most likely or primary intermediates and computing their concentrations. Here this model is applied to Murine Polyomavirus based on the a...
متن کاملIn vitro assembly of virus-like particles of a gammaretrovirus, the murine leukemia virus XMRV.
Immature retroviral particles are assembled by self-association of the structural polyprotein precursor Gag. During maturation the Gag polyprotein is proteolytically cleaved, yielding mature structural proteins, matrix (MA), capsid (CA), and nucleocapsid (NC), that reassemble into a mature viral particle. Proteolytic cleavage causes the N terminus of CA to fold back to form a β-hairpin, anchore...
