General Information | Comment | Organism |
---|---|---|
physiological function | enzyme acts as a bifunctional glycosyltransferase, with both xylosyltransferase and glucuronyltransferase activities, producing repeating units of [3-alpha-D-xylosyl-(1->3)-beta-D-glucuronyl-1-]. LARGE synthesizes the polymer on the O-mannosyl glycan of alpha-dystroglycan in vivo. The LARGE-synthesized, negatively charged glycan on alpha-dystroglycan likely binds to laminin through electrostatic associations with these basic patches | Homo sapiens |
