In addition to N-linked glycosylation, O-linked glycosylation is believed to be involved in Nrf1 transcription activity.
The synthesized UDP-GlcNAc is transported from ER to the Golgi apparatus via the UDP-GlcNAc transporters and is then utilized as a donor substrate for the N- and O-linked glycosylation of extracellular and membrane proteins [9, 10].

The O-linked glycosylation (also known as mucin type) is initiated in the Golgi compartment of human cells by the transfer of monosaccharide N-acetylgalactosamine (GalNAc) from UDP-GalNAc to the hydroxyl groups of Ser/Thr residues in core polypeptides by a large family (~20) of GalNAc-transferases (ppGalNac-Ts or GalNAc-Ts; E.C.
