Predicted to enable 4-galactosyl-N-acetylglucosaminide 3-alpha-L-fucosyltransferase activity. Involved in leukocyte migration; regulation of cellular extravasation; and regulation of type IV hypersensitivity. Acts upstream of or within CD4-positive, CD25-positive, alpha-beta regulatory T cell differentiation and leukocyte migration involved in immune response. Predicted to be located in trans-Golgi network. Orthologous to human FUT7 (fucosyltransferase 7). [provided by Alliance of Genome Resources, Apr 2022]
