Predicted to enable UDP-N-acetylglucosamine transmembrane transporter activity and UDP-xylose transmembrane transporter activity. Predicted to be involved in UDP-N-acetylglucosamine transmembrane transport and UDP-xylose transmembrane transport. Predicted to act upstream of or within regulation of gluconeogenesis. Predicted to be located in Golgi apparatus and endoplasmic reticulum. Predicted to be integral component of Golgi membrane and integral component of endoplasmic reticulum membrane. Orthologous to human SLC35B4 (solute carrier family 35 member B4). [provided by Alliance of Genome Resources, Apr 2022]
