CC   -!- FUNCTION: Catalyzes alpha(1->3) linkage of fucosyl moiety transferred
CC       from GDP-beta-L-fucose to N-acetyl glucosamine (GlcNAc) within type 2
CC       lactosamine (LacNAc, Gal-beta(1->4)GlcNAc) glycan attached to N- or O-
CC       linked glycoproteins. Robustly fucosylates nonsialylated distal LacNAc
CC       unit of the polylactosamine chain to form Lewis X antigen (CD15), a
CC       glycan determinant known to mediate important cellular functions in
CC       development and immunity. Fucosylates with lower efficiency sialylated
CC       LacNAc acceptors to form sialyl Lewis X and 6-sulfo sialyl Lewis X
CC       determinants that serve as recognition epitopes for C-type lectins.
CC       Together with FUT7 contributes to SELE, SELL and SELP selectin ligand
CC       biosynthesis and selectin-dependent lymphocyte homing, leukocyte
CC       migration and blood leukocyte homeostasis (By similarity). In a cell
CC       type specific manner, may also fucosylate the internal LacNAc unit of
CC       the polylactosamine chain to form VIM-2 antigen that serves as
CC       recognition epitope for SELE (By similarity).
