GGDB:

β1,4-N-acetylgalactosaminyltransferase- IV (B4GALNT4)はUDP-GalNAcのGalNAcをGlcNAcβ-Rに転移しN-およびO-グリカン上のN,N'-diacetyllactosamine, GalNAcβ1→4GlcNAc (LacdiNAc)を合成する。B4GALNT4はB4GalNac-T4およびNGalNAc-T1としても知られる。B4GALNT3とB4GALNT4はともにルトロピン（LH）、サイロトロピン（TSH）、zona pellucida 3（ZP3）を含む様々な糖タンパク質および細胞外基質糖タンパク質でLacdiNAc構造を合成する。これら二つの糖転移酵素の発現パターンは異なっている。
