The baculoviral inhibitors of apoptosis play a significant role in infectivity and viral host-range, which make them potential candidates for the engineering and improvement of baculovirus insecticidal. The iap3 gene of Spodoptera exigua nucleopolyhedrovirus (SeMNPV), amplified by PCR, was 939 bp encoding IAP3. The PCR product was cloned into EcoR I /Bam H I of the plasmid pEGFP-C1. GFP was fused to the N-terminaus of IAP3 to study distribution in HEK293. It was observed that the plasmid expressing IAP3 significantly inhibited apoptosis induced by cisplatin in HEK293 cells. We conclude that the IAP3 of SeMNPV is functional in mammalian cells.
