Funkcija[uredi | uredi izvor]

Ovaj gen kodira jedan od dva endoplazmatskoretikulimska rezidentna transmembranska tipa II glikoziltransferaza – drugi je EXT2 – koji su uključeni u korak biosinteze elongacije lanca heparan-sulfata. Mutacije u ovom genu uzrokuju oblik I tipa višestruke egzostoze.^[5]

Interakcije[uredi | uredi izvor]

Pokazano je da EXT1 stupa u interakciju sa TRAP1.^[7]
