Catalysis of the transfer of an N-acetylglucosaminyl residue from UDP-N-acetyl-glucosamine to an oligosaccharide. 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-glucosamine + beta-D-mannosyl-R = UDP + 4-(N-acetyl-beta-D-glucosaminyl)-beta-D-mannosyl-R.
