CC   -!- FUNCTION: Beta-1,3-galactosyltransferase that transfers galactose from
CC       UDP-galactose to substrates with a terminal beta-N-acetylglucosamine
CC       (beta-GlcNAc) residue. Involved in the biosynthesis of the carbohydrate
CC       moieties of glycolipids and glycoproteins.
CC       {ECO:0000250|UniProtKB:Q9Y5Z6}.
