CC -!- FUNCTION: Glycosyltransferase involved in the xylosylation of N-glycans
CC (PubMed:10781814, PubMed:12943552, PubMed:15013764, PubMed:15686448).
CC Possesses beta-1,2-xylosyltransferase activity, transferring xylose
CC from UDP-xylose to the core beta-linked mannose of N-glycans
CC (PubMed:10781814, PubMed:12943552, PubMed:15013764, PubMed:15686448).
CC Involved in the biosynthesis of glycoprotein bound N-glycans
CC (PubMed:15686448, PubMed:22024534). Does not require metal ions for its
CC activity (PubMed:15686448). {ECO:0000269|PubMed:10781814,

CC Evidence={ECO:0000269|PubMed:10781814, ECO:0000269|PubMed:22024534};
CC -!- PATHWAY: Protein modification; protein glycosylation. {ECO:0000305}.
CC -!- SUBCELLULAR LOCATION: Golgi apparatus membrane
CC {ECO:0000269|PubMed:12175019, ECO:0000269|PubMed:12943552}; Single-pass
CC type II membrane protein {ECO:0000269|PubMed:12175019,
CC ECO:0000269|PubMed:12943552}. Note=Localizes in medial cisternae of
CC Golgi apparatus. {ECO:0000269|PubMed:12943552}.
CC -!- PTM: Glycosylation at least at one of the two sites Asn-51 and Asn-301
CC is necessary for enzyme stability and activity.
CC {ECO:0000269|PubMed:12943552}.
CC -!- MISCELLANEOUS: Renders plant glycoproteins immunogenic and allergenic
CC in human. This is due to the presence of beta-1,2-xylose and/or core
CC alpha-1,3-fucose which are not found in mammalian proteins, and which
CC constitute epitopes for carbohydrate-reactive antibodies.
