Enables alpha-(1->3)-fucosyltransferase activity. Predicted to be involved in fucosylation; oligosaccharide metabolic process; and positive regulation of leukocyte tethering or rolling. Predicted to be located in cell periphery; cell surface; and trans-Golgi network. Orthologous to human FUT4 (fucosyltransferase 4). [provided by Alliance of Genome Resources, Apr 2022]
