39. Glycoforms add yet more variation-- Whereas a protein is defined by its unique amino acid sequence, the glycan structure at a single protein glycosylation site varies. Although glycan structures vary at each glycosylation site, the profile is reproducible, protein-specific, site- specific, and cell type-specific.

52.  O-GlcNAc is localized to the cytoplasm and nucleus.  O-GlcNAc is present in all higher eukaryotes studied.  O-GlcNAc is as abundant as phosphorylation.  UDP-GlcNAc is as abundant as ATP in some cell types.  O-GlcNAc containing proteins are phosphoproteins.  O-GlcNAc and phosphorylation are often reciprocal.  O-GlcNAc is dynamic, implying a regulatory role.
