Enables 4-galactosyl-N-acetylglucosaminide 3-alpha-L-fucosyltransferase activity. Involved in cellular polysaccharide biosynthetic process and fucosylation. Acts upstream of or within protein glycosylation. Located in Golgi apparatus. Is expressed in brain; central nervous system; and telencephalon. Orthologous to human FUT9 (fucosyltransferase 9).
