Catalysis of the transfer of a galactose group from UDP-galactose to an acceptor molecule. Catalysis of the reaction: UDP-galactose + O-beta-D-xylosylprotein = UDP + 4-beta-D-galactosyl-O-beta-D-xylosylprotein. Catalysis of the transfer of a glycosyl group from a UDP-sugar to a small hydrophobic molecule. Catalysis of the transfer of a galactosyl group to an acceptor molecule, typically another carbohydrate or a lipid.
