title: Characterization of p24 gene of Spodoptera litura multicapsid nucleopolyhedrovirus.
abstract: Spodoptera litura multicapsid nucleopolyhedrovirus (SpltMNPV) p24 gene is 753 bp long, potentially encoding 244 amino acids with a predicted molecular weight of 27.3 kDa. Homology analysis indicated that SpltMNPV P24 has 20-36% amino acid identity with that of other known baculoviruses. RT-PCR results showed that the p24 gene is transcribed actively at the late stage of infection and the mRNA start site was mapped within a consensus baculovirus late promoter sequence (ATAAG). Western blot analysis of extracts from SpltMNPV-infected S. litura cells detected a specific 28 kDa protein, and this protein was not N-glycosylated. Structural localization revealed that SpltMNPV P24 was associated with the nucleocapsid of occlusion-derived virus (ODV) as a complex form of 83 kDa.
