Although it displays a much weaker activity toward all substrates tested compared to GALNT2, it is able to transfer up to seven GalNAc residues to the Muc5AC peptide, suggesting that it can fill vicinal Thr/Ser residues in cooperation with other GALNT proteins. Prefers Muc1a as substrate. |Glycos transf 2| |Ricin B lectin| |polypeptide N-acetylgalactosaminyltransferase activity| |O-glycan processing| |transport vesicle| |protein O-linked glycosylation| |carbohydrate binding| |macromolecule glycosylation| |protein glycosylation| |glycosylation| |glycoprotein biosynthetic process| |glycoprotein metabolic process| |Golgi membrane| |carbohydrate derivative biosynthetic process| |Golgi apparatus| |carbohydrate derivative metabolic process| |organonitrogen compound biosynthetic process| |cellular macromolecule biosynthetic process| |macromolecule biosynthetic process| \\ === CRISPR Data === No hits were found.
