Predicted to enable UDP-glycosyltransferase activity and protein dimerization activity. Predicted to be involved in glycosaminoglycan biosynthetic process; heparan sulfate proteoglycan biosynthetic process, polysaccharide chain biosynthetic process; and ossification. Predicted to act upstream of or within with a positive effect on gene expression; protein N-linked glycosylation; and sulfation. Predicted to act upstream of or within several processes, including heparan sulfate proteoglycan biosynthetic process; heparin biosynthetic process; and sodium ion homeostasis. Predicted to be located in endoplasmic reticulum. Predicted to be part of UDP-N-acetylglucosamine transferase complex. Predicted to be active in Golgi apparatus. Orthologous to human EXT2 (exostosin glycosyltransferase 2). [provided by Alliance of Genome Resources, Apr 2022]
