Has a much stronger activity than GALNT1 to transfer GalNAc to mucin peptides, such as Muc5Ac and Muc7. Able to glycosylate SDC3. May be responsible for the synthesis of Tn antigen in neuronal cells. |Ricin B lectin| |Glycos transf 2| |protein O-linked glycosylation via threonine| |protein O-linked glycosylation via serine| |polypeptide N-acetylgalactosaminyltransferase activity| |O-glycan processing| |peptidyl-threonine modification| |protein O-linked glycosylation| |carbohydrate binding| |peptidyl-serine modification| |macromolecule glycosylation| |protein glycosylation| |glycosylation| |glycoprotein biosynthetic process| |glycoprotein metabolic process| |carbohydrate derivative biosynthetic process| |Golgi membrane| |peptidyl-amino acid modification| |Golgi apparatus| |carbohydrate derivative metabolic process| |organonitrogen compound biosynthetic process| |cellular macromolecule biosynthetic process| |macromolecule biosynthetic process| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp528|TGF-beta1 44ng/ml R08 exp528]]|-1.84| |[[:results:exp524|Staurosporine 0.02μM R08 exp524]]|-1.77| No correlation found to any other genes in chemogenomics.
