Catalysis of the transfer of an N-acetylglucosaminyl residue from UDP-N-acetyl-glucosamine to an oligosaccharide. Catalysis of the reaction: UDP-N-acetyl-D-glucosamine + alpha-D-mannosyl-1,3-(R1)-beta-D-mannosyl-R2 = UDP + N-acetyl-beta-D-glucosaminyl-1,2-alpha-D-mannosyl-1,3-(R1)-beta-D-mannosyl-R2. 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.
