The enzyme from human can transfer N-acetyl-D-galactosamine (GalNAc) to N-glycan and O-glycan substrates that have N-acetyl-D-glucosamine (GlcNAc) but not D-glucuronic acid (GlcUA) at their non-reducing end. The N-acetyl-beta-D-glucosaminyl group is normally on a core oligosaccharide although benzyl glycosides have been used in enzyme-characterization experiments. Some glycohormones, e.g. lutropin and thyrotropin contain the N-glycan structure containing the N-acetyl-beta-D-galactosaminyl-(1->4)-N-acetyl-beta-D-glucosaminyl group.

LITERATURE
malfunction
B4GALNT3 overexpression enhances colon cancer cell malignant phenotypes in vitro and in vivo. B4GALNT3 knockdown suppresses EGF-induced phosphorylation of epithelial growth factor receptor, EGFR, and its downstream signaling molecules. B4GALNT3 knockdown inhibits EGFR activity, decreases EGF-induced migration and invasion in colon cancer cells, and promotes EGFR degradation in colon cancer cells, overview
physiological function
beta1,4-N-acetylgalactosaminyltransferase III modulates cancer stemness through EGFR signaling pathway in colon cancer cells, B4GALNT3 regulates cancer stemness and the invasive properties of colon cancer cells through modifying EGFR glycosylation and signaling. B4GALNT3 expression is positively correlated with advanced stages and poor survival in colorectal cancer patients
