β3-Galactosyltransferase (β3GalT) transfers a galactose from UDP-Gal to N- acetylglucosamine (GlcNAc) with a β1,3-linkage. To date, five members of the β3GalT family have been cloned and analyzed (Issiki et al. 1999). β3GalT-I was first cloned by an expression cloning method (Sasaki et al. 1994). The other three members, β3GalT- II-IV, which have homologous sequences to β3GalT-I were found in the EST database and cloned (Issiki et al. 1999; Kolbinger et al. 1998; Amado et al. 1998; Hennet et al. 1998).
