An overview of the process of N-glycosylation. Glycosyltransferases involved in the synthesis are indicated. Additional modifications exist (not shown). Dol dolichopyrophosphate, MGAT β1,6-N-acetylglucosaminyltransferase, MANII mannosidase II, GlcNAc N-acetylglucosamine, Man mannose, Gal galactose, NeuAc N-acetylneuraminic acid, Fuc fucose. Glycosyltransferases shown in Table 1 are highlighted, except B4GALNT3
