Glucoside Xylosyltransferase 2; Glycosyltransferase 8 Domain-Containing Protein 4; Glycosyltransferase 8 Domain Containing 4; GLT8D4; EC 2.4.2.n2; EC 2.4.1

The protein encoded by this gene is a xylosyltransferase that elongates O-linked glucose bound to epidermal growth factor (EGF) repeats. The encoded protein catalyzes the addition of xylose to the O-glucose-modified residues of EGF repeats of Notch proteins.
