Function | Responsible for the 2-O-dephosphorylation of xylose in the glycosaminoglycan-protein linkage region of proteoglycans thereby regulating the amount of mature glycosaminoglycan (GAG) chains. Sulfated glycosaminoglycans (GAGs), including heparan sulfate and chondroitin sulfate, are synthesized on the so-called common GAG-protein linkage region (GlcUAbeta1-3Galbeta1-3Galbeta1- 4Xylbeta1-O-Ser) of core proteins, which is formed by the stepwise addition of monosaccharide residues by the respective specific glycosyltransferases. Xylose 2-O-dephosphorylation during completion of linkage region formation is a prerequisite for the initiation and efficient elongation of the repeating disaccharide region of GAG chains. {ECO:0000269|PubMed:24425863}. |
Subcellular Location | Golgi apparatus membrane {ECO:0000269|PubMed:24425863}; Single-pass type II membrane protein {ECO:0000255}. Note=Colocalizes to Golgi apparatus in a B3GAT3-dependent manner. {ECO:0000269|PubMed:24425863}. |
Tissue Specificity | Widely expressed. Strongly expressed in spleen, fetal liver, moderately in placenta, pancreas, kidney, thymus and colon. {ECO:0000269|PubMed:24425863}. |
