Abstract Orf94 (Bm94) of Bombyx mori nucleopolyhedrovirus (BmNPV) potentially encodes 424-amino acids with a predicted molecular weight of 49.4 kDa, but its function remains unknown. Blast search results revealed that Bm94 homologues exist in 10 completely sequenced Lepidopteron NPVs with identities ranging from 95 to 37\%. Results of our recent study showed that Bm94 was transcribed from 12 to 72 h and the corresponding protein was detected from 24 to 72 h post-infection. Furthermore, Western blot analysis revealed that Bm94 was present in occlusion-derived virus (ODV) and in total protein from BmNPV-infected BmN cells, but not in budded virus. Immunofluorescence analysis revealed that the protein located primarily in the cytoplasm and was also present in the nucleus in the later infection. In conclusion, these results together indicated that Bm94 was a late gene, which distributed both in the cytoplasm and in the nucleus, and was identified to be a component of BmNPV ODV.
