Area of Science:

  • Biotechnology
  • Molecular Biology
  • Glycobiology

Background:

  • The baculovirus-insect cell expression system is widely used for recombinant protein production.
  • A significant limitation is its inability to generate complex N-linked glycans on eukaryotic glycoproteins.
  • This restricts the utility of the system for producing certain therapeutic proteins.

Purpose of the Study:

  • To address the limitation of complex N-glycan synthesis in insect cells.
  • To develop metabolically engineered insect cell lines with enhanced glycoprotein processing.
  • To create improved baculovirus-insect cell expression systems for authentic glycoprotein production.

Main Methods:

  • Metabolic engineering of lepidopteran insect cells.
  • Modification of N-glycosylation pathways.
