Predicted to enable GDP-fucose transmembrane transporter activity and antiporter activity. Predicted to be involved in GDP-fucose import into Golgi lumen and protein O-linked fucosylation. Predicted to act upstream of or within lipid glycosylation and negative regulation of Notch signaling pathway. Predicted to be integral component of membrane. Predicted to be active in Golgi apparatus. Human ortholog(s) of this gene implicated in congenital disorder of glycosylation type IIc. Orthologous to human SLC35C1 (solute carrier family 35 member C1). [provided by Alliance of Genome Resources, Apr 2022]
