Predicted to enable antiporter activity and pyrimidine nucleotide-sugar transmembrane transporter activity. Predicted to be involved in UDP-N-acetylgalactosamine transmembrane transport; UDP-N-acetylglucosamine transmembrane transport; and UDP-glucuronic acid transmembrane transport. Predicted to act upstream of or within chondroitin sulfate biosynthetic process; embryonic skeletal system development; and pyrimidine nucleotide-sugar transmembrane transport. Predicted to be located in endoplasmic reticulum. Predicted to be active in Golgi apparatus. Human ortholog(s) of this gene implicated in schneckenbecken dysplasia. Orthologous to human SLC35D1 (solute carrier family 35 member D1). [provided by Alliance of Genome Resources, Apr 2022]
