| epitope insertion at the n-terminal molecular switch of the rabbit hemorrhagic disease virus t = 3 capsid protein leads to larger t = 4 capsids. | viruses need only one or a few structural capsid proteins to build an infectious particle. this is possible through the extensive use of symmetry and the conformational polymorphism of the structural proteins. using virus-like particles (vlp) from rabbit hemorrhagic disease virus (rhdv) as a model, we addressed the basis of calicivirus capsid assembly and their application in vaccine design. the rhdv capsid is based on a t=3 lattice containing 180 identical subunits (vp1). we determined the stru ... | 2012 | 22491457 |
| identification of human junctional adhesion molecule 1 as a functional receptor for the hom-1 calicivirus on human cells. | the hom-1 vesivirus was reported in 1998 following the inadvertent transmission of the animal calicivirus san miguel sea lion virus to a human host in a laboratory. we characterized the hom-1 strain and investigated the mechanism by which human cells could be infected. an expression library of 3,559 human plasma membrane proteins was screened for reactivity with hom-1 virus-like particles, and a single interacting protein, human junctional adhesion molecule 1 (hjam1), was identified. transient e ... | 2017 | 28196955 |
| the complete genome sequence of the san miguel sea lion virus-8 reveals that it is not a member of the vesicular exanthema of swine virus/san miguel sea lion virus species of the caliciviridae. | the complete genome sequence of the san miguel sea lion virus-8 (smsv-8) was determined in this study. a comparison of this sequence to other calicivirus sequences in genbank showed that this virus is genetically distinct from the vesicular exanthema of swine virus/san miguel sea lion virus (vesv/smsv) strains and belongs to a novel clade within the vesivirus genus. | 2014 | 25502676 |
| calicivirus antibodies in wild fox populations. | three populations of wild foxes were sampled for serum neutralizing antibody to calicivirus (san miguel sea lion virus) types 1-5. neutralizing activity was detected in serum from gray foxes resident on santa cruz island, california, but not in arctic foxes from alaska. the results indicate that foxes may be naturally infected with caliciviruses, but their role in the transmission cycle is unknown. | 1977 | 24228972 |
