The fp25k gene of Helicoverpa armigera single nucleocapsid nucleopolyhedrovirus (HearNPV) was studied. HearNPV fp25k gene transcription was found starting from about 18 h post-infection, and protein could be detected from the same time with antiserum against FP25K. To study the function of HearNPV fp25k, a recombinant HearNPV (HaBacWD11) with an enhanced green fluorescent protein (GFP) gene rep...

Human 29IJ6 IgG was expressed in silkworm using a Bombyx mori 25 nucleopolyhedrovirus (BmNPV) bacmid system. The mean amounts of 296IJ6 IgG 26 produced in larval hemolymph and whole pupae were 30.1 μg/larva and 78.0 μg/pupa,

Homologs to Autographa californica multiple nucleopolyhedrovirus (AcMNPV) open reading frame (ORF) 136 or Acp26 are present within almost all nucleopolyhedroviruses (NPVs). Two copies of the gene are found in some members of group II NPVs, suggesting that it may play an important role in transmission or replication. Phylogenetic analysis revealed that the predicted protein has some similarity w...

The Autographa californica multiple nucleopolyhedrovirus orf92 (p33), ac92, is one of 31 genes carried in all sequenced baculovirus genomes, thus suggesting an essential function. Ac92 has homology to the family of flavin adenine dinucleotide-linked sulfhydryl oxidases and is related to the ERV/ALR family of sulfhydryl oxidases. The role of ac92 during virus replication is unknown. Ac92 was ass...

Theileria parva is an intracellular protozoan parasite that causes East Coast fever, a severe lymphoproliferative disease in cattle. Previous attempts to produce recombinant sporozoite surface antigen (p67) in bacterial or insect cells for vaccine purposes have not resulted in a correctly folded protein. Here, we report the expression of N- and C-terminal domains of p67 fused to the baculovirus...

Tuftelin is an acidic protein expressed at very early stages of mouse odontogenesis. It was suggested to play a role during epithelial-mesenchymal interactions, and later, when enamel formation commences, to be involved in enamel mineralization. Tuftelin was also detected in several normal soft tissues of different origins and some of their corresponding cancerous tissues. Tuftelin is expressed...

Genetically modified baculoviruses offer a promising alternative to chemical insecticides in the control of agricultural and forest insect pests. A novel bacmid, HaBacYH6, was constructed in which the ecdysteroid UDP-glucosyltransferase gene (egt) was replaced with a bacterial replication cassette containing a mini-F replicon, a kanamycin resistance gene, and the attTn7 site. Insertion of the e...
