Beta-1,4-galactosyltransferase 1 (B4GALT1) is a Golgi membrane enzyme responsible for galactosylation of N-acetylglucosaminyl group added by fringe enzymes to O-linked fucosyl residues on NOTCH. This results in formation of trisaccharide chains on NOTCH (Gal-beta1,4-GlcNAc-beta1,3-fucitol), and is a necessary step for fringe-mediated modulation of NOTCH signaling.
