Function Probably catalyzes the first step in biosynthesis of glycosaminoglycan. Transfers D-xylose from UDP-D-xylose to specific serine residues of the core protein. Initial enzyme in the biosynthesis of chondroitin sulfate and dermatan sulfate proteoglycans in fibroblasts and chondrocytes (By similarity). Its enzyme activity has not been demonstrated. {ECO:0000250}.
Subcellular Location Endoplasmic reticulum membrane {ECO:0000250}; Single-pass type II membrane protein {ECO:0000250}. Golgi apparatus membrane {ECO:0000250}; Single-pass type II membrane protein {ECO:0000250}.
Tissue Specificity Widely expressed. Expressed at higher level in kidney and pancreas. {ECO:0000269|PubMed:11099377}.
Top Pathways Glycosaminoglycan biosynthesis - chondroitin sulfate / dermatan sulfate, Glycosaminoglycan biosynthesis - heparan sulfate / heparin
