Localization and functional analysis of SeMNPV IE1 in mammalian cells.

In this paper, the function of the ie1 gene from baculovirus Spodoptera exigua multiple nucleopolyhedrovirus (SeMNPV), belonging to group II nucleopolyhedrovirus, was studied in mammalian cells. We amplified the SeMNPV ie1 gene and expressed it by fusing to the C terminal of enhanced GFP protein in HEK 293 cells. Confocal microscopy revealed that the IE1-GFP fusion protein was localized in the nucleus of the mammalian cells.
