The encoded protein synthesizes GalNAc:beta-1,3GlcNAc, a novel carbohydrate structure, on N- and O-glycans. Alternatively spliced transcript variants that encode different isoforms have been described. [provided by RefSeq, Mar 2013]. * **UniProt Summary**: Beta-1,3-N-acetylgalactosaminyltransferase that synthesizes a unique carbohydrate structure, GalNAc-beta-1- 3GlcNAc, on N- and O-glycans. Has no galactose nor galactosaminyl transferase activity toward any acceptor substrate. Involved in alpha-dystroglycan (DAG1) glycosylation: acts coordinately with GTDC2/POMGnT2 to synthesize a GalNAc-beta3-GlcNAc-beta-terminus at the 4-position of protein O-mannose in the biosynthesis of the phosphorylated O-mannosyl trisaccharide (N-acetylgalactosamine- beta-3-N-acetylglucosamine-beta-4-(phosphate-6-)mannose), a carbohydrate structure present in alpha-dystroglycan, which is required for binding laminin G-like domain-containing extracellular proteins with high affinity. {ECO:0000269|PubMed:14724282, ECO:0000269|PubMed:23453667, ECO:0000269|PubMed:23929950}. |Galactosyl T| |galactosyltransferase activity| |acetylgalactosaminyltransferase activity| |acetylglucosaminyltransferase activity| |protein O-linked glycosylation| |macromolecule glycosylation| |protein glycosylation| |glycosylation| |glycoprotein biosynthetic process| |glycoprotein metabolic process| |carbohydrate derivative biosynthetic process| |Golgi membrane| |endoplasmic reticulum membrane| |Golgi apparatus| |endoplasmic reticulum| |carbohydrate derivative metabolic process| |organonitrogen compound biosynthetic process| |cellular macromolecule biosynthetic process| |macromolecule biosynthetic process| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp488|Hippuristanol 0.12μM R08 exp488]]|-1.95| |[[:results:exp433|LJH685 50μM R08 exp433]]|-1.81| |[[:results:exp447|Amiloride 100μM R08 exp447]]|-1.72| |[[:results:exp123|GSK-LSD1 10μM R03 exp123]]|2.25| No correlation found to any other genes in chemogenomics.
