 Xylo_C
PFAM accession number:PF12529
Interpro abstract (IPR024448):

This domain is found in metazoan xylosyltransferases, which include xylosyltransferase 1 and xylosyltransferase 2. These enzymes initiate the biosynthesis of glycosaminoglycan chains in proteoglycans by transferring xylose from UDP-xylose to specific serine residues of the core protein [ (PUBMED:11099377) ].

This is a PFAM domain. For full annotation and more information, please see the PFAM entry Xylo_C
