based on mapping to UniProt Q3TUA9
ATP + O(3)-(N-acetyl-beta-D-galactosaminyl-(1->3)-N-acetyl-beta-D- glucosaminyl-(1->4)-alpha-D-mannosyl)-L-threonyl/L-seryl-[protein] = ADP + O(3)-(N-acetyl-beta-D-galactosaminyl-(1->3)-N-acetyl-beta-D- glucosaminyl-(1->4)-alpha-D-(6-phospho)mannosyl)-L-threonyl/L-seryl- [protein].
-!- In humans this phosphorylated trisaccharide is attached to an L-threonine residue of alpha-dystroglycan, an extracellular peripheral glycoprotein that acts as a receptor for extracellular matrix proteins containing laminin-G domains, and is important for its activity.
