UDP-GlcNAc Transporter

  • Masao Kawakita

The Golgi and rough endoplasmic reticulum (ER) membranes have an activity that transports UDP-GlcNAc from the cytosol into their lumens (Perez and Hirschberg 1985; Bossuyt and Blanckaert 1994). The nucleotide sugar transported to the Golgi lumen serves as a substrate of GlcNAc transferases for the elongation of carbohydrate chains of glycoproteins, glycolipids, and proteoglycans. On the other hand, the reactions in which UDP-GlcNAc is utilized in the ER have not yet been definitively identified.
