Insect cell lines have been used extensively for the production of numerous functional eukaryotic proteins. However, insect cell systems have limited commercial use due to a lack of complex glycosylation. Glycosylation is very crucial factor for use of pharmaceutical proteins. While, baculovirus is used as a strong gene delivery carrier for transfection of insect cells. Especially, Drosophila S2 cells have been developed as a plasmid-based and non-lytic expression system using recombinant baculovirus, infects into insect cells and does not require any selection markers. A gene encoding human erythropoietin (hEPO) or human 90K (h90K) fused with a hexa- histidine (His6) tag under the control of the Drosophila originated metallothionein promoter (pMT) was stably transfected into Drosophila S2 cells. In the preliminary studies, we found that expressed proteins had simple N-glycan structures instead of complex structures. We thought that this result caused by N-acetylglucosaminidase (GlcNAcase) through enzyme assay experiment. Therefore, this research will propose that suppression of GlcNAcase and several expression of N-glycosyltransferases using recombinant baculovirus- based multiple protein expression platform.
