Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

Glycosyltransferase involved in the xylosylation of N-glycans (PubMed:10781814, PubMed:12943552, PubMed:15013764, PubMed:15686448). Possesses beta-1,2-xylosyltransferase activity, transferring xylose from UDP-xylose to the core beta-linked mannose of N-glycans (PubMed:10781814, PubMed:12943552, PubMed:15013764, PubMed:15686448). Involved in the biosynthesis of glycoprotein bound N-glycans (PubMed:15686448, PubMed:22024534). Does not require metal ions for its activity (PubMed:15686448).5 Publications

Miscellaneous

Renders plant glycoproteins immunogenic and allergenic in human. This is due to the presence of beta-1,2-xylose and/or core alpha-1,3-fucose which are not found in mammalian proteins, and which constitute epitopes for carbohydrate-reactive antibodies.1 Publication
