N-Acetylgalactosaminyltransferase 1 (GALNT1) is a glycosyltransferase that initiates mucin-type O-glycosylation by transferring alpha-GalNAc from UDP-GalNAc to serine (Ser) or threonine (Thr) residues in proteins. Overexpression of N-Acetylgalactosaminyltransferase 1 in gastric cancer can promote abnormal O-glycosylation of CD44, thereby activating the Wnt/beta-catenin signaling pathway and regulating the malignant behavior of gastric cancer cells. Additionally, N-Acetylgalactosaminyltransferase 1 plays a crucial role in cancer growth and metastasis by modifying the O-glycosylation of various glycoproteins, such as mucin (MUC1), osteopontin (OPN), matrix metalloproteinase-14 (MMP14), and integrin alpha3[1].
