Enables N-acetyl-beta-glucosaminyl-glycoprotein 4-beta-N-acetylgalactosaminyltransferase activity and beta-1,4-N-acetylgalactosaminyltransferase activity. Involved in several processes, including N-acetylglucosamine metabolic process; adult locomotory behavior; and glycosphingolipid biosynthetic process. Located in Golgi apparatus. Is expressed in embryonic/larval garland cell and organism. Human ortholog(s) of this gene implicated in congenital disorder of glycosylation and congenital disorder of glycosylation type IId. Orthologous to several human genes including B4GALT1 (beta-1,4-galactosyltransferase 1); B4GALT2 (beta-1,4-galactosyltransferase 2); and B4GALT3 (beta-1,4-galactosyltransferase 3).
FB Description
beta1,4-N-acetylgalactosaminyltransferase A (beta4GalNAcTA) encodes a acetylgalactosaminyltransferase involved in glycolipid biosynthesis. It contributes to the development of the neuromuscular junction.
