Question

N-glycosylation is a process in which a carbohydrate moiety is added to the amide nitrogen of the asparagine (N) residue of a protein in the endoplasmic reticulum. This modification is important for protein folding, stability, and targeting. Since glycans increase the hydrophilicity of proteins, N-glycosylation is often used as a signal for protein secretion. Therefore, a protein that is N-glycosylated is expected to be secreted from the cell.
