General annotation (Comments)

Function	Glycosyltransferase that participates in the transfer of N-acetylglucosamine (GlcNAc) to the core mannose residues of N-linked glycans. Catalyzes the formation of the GlcNAcbeta1-4 branch on the GlcNAcbeta1-2Manalpha1-3 arm of the core structure of N-linked glycans By similarity.
Catalytic activity	UDP-N-acetyl-D-glucosamine + 3-(2-(N-acetyl-beta-D-glucosaminyl)-alpha-D-mannosyl)-beta-D-mannosyl-R = UDP + 3-(2,4-bis(N-acetyl-beta-D-glucosaminyl)-alpha-D-mannosyl)-beta-D-mannosyl-R.
Cofactor	Divalent metal cations By similarity.
Pathway	Protein modification; protein glycosylation.
Subcellular location	Golgi apparatus membrane; Single-pass type II membrane protein By similarity.
Sequence similarities	Belongs to the glycosyltransferase 54 family.
