About This Section

EntrezGene summary for A4GNT:
This gene encodes a protein from the glycosyltransferase 32 family. The enzyme catalyzes the
transfer of N-acetylglucosamine (GlcNAc) to core 2 branched O-glycans. It forms a unique glycan,
GlcNAcalpha1-->4Galbeta-->R and is largely associated with the Golgi apparatus membrane.
[provided by RefSeq]

UniProtKB/Swiss-Prot: A4GCT_HUMAN, Q9UNA3
Function: Necessary for the synthesis of type III mucin. Catalyzes the transfer of
N-acetylglucosamine (GlcNAc) to core 2 branched O-glycans
