Control of Protein Glycosylation and Compositions and Methods Relating Thereto

摘要

The invention relates to novel methods for controlling the glycosylation of a protein and the protein produced thereby. An exemplary method of the invention comprises producing a protein comprising a decreased level of glycosylation, e.g., the protein comprises fewer glycans or fewer saccharides at the glycosylation site, by culturing a host cell expressing the protein in the presence of a glycosylation inhibitor. In an exemplary method of the invention, the biological characteristics of the protein are altered by the decreased level of glycosylation, e.g., the binding of the protein with its target ligand is modified.
