Catalysis of the transfer of a hexosyl group from one compound (donor) to another (acceptor). Catalysis of the transfer of a glycosyl group from a UDP-sugar to a small hydrophobic molecule. Catalysis of the reaction: UDP-N-acetyl-D-galactosamine + N-acetyl-beta-D-glucosaminyl group = UDP + N-acetyl-beta-D-galactosaminyl-(1->4)-N-acetyl-beta-D-glucosaminyl group. Catalysis of the transfer of an N-acetylgalactosaminyl residue from UDP-N-acetyl-galactosamine to an oligosaccharide.
