N-acetilaktosaminid beta-1,3-N-acetilglukozaminiltransferazajeenzimkoji je kodljudi kodiran genomB3GNT1.^[5]^[6]

β-1,4-glukuroniltransferaza

GenB3GNT1kodira β-1,4-glukuroniltransferazu, označenu kao B4GAT1, koja prenosi glukuronsku kiselinu prema α- i β-anomerima ksiloze.^[7]B4GAT1 je primarni enzim za LARGE, glikoziltransferazu dvostruke aktivnosti koja je sposobna produžiti produkte B4GAT1. Stoga je uključen u započinjanje velikog ovisnog ponavljajućegdisaharidakoji je neophodan za vezivanje proteinavanćelijskog matriksaza O-manosilirani α-distroglikan, koji nedostaje u sekundarnim distroglikanopatijama.

Pogrešna identifikacija

Za gen B3GNT1 prvi put je objavljeno da kodira člana porodice beta-1,3-N-acetilglukozaminiltransferaze i smatralo se da je odgovoran za sintezu poli-N-acetilaktosamina,^[5]determinante zaantigen krvne grupei.Tako je bio poznat i kao iGNT.
