| Reaction: |
ATP + O3-[N-acetyl-β-D-galactosaminyl-(1→3)-N-acetyl-β-D-glucosaminyl-(1→4)-α-D-mannosyl]-L-threonyl/L-seryl-[protein] = ADP + O3-[N-acetyl-β-D-galactosaminyl-(1→3)-N-acetyl-β-D-glucosaminyl-(1→4)-α-D-(6-phospho)mannosyl]-L-threonyl/L-seryl-[protein] |

| Other name(s): |
SGK196; protein O-mannose kinase |
| Systematic name: |
ATP:O3-[N-acetyl-β-D-galactosaminyl-(1→3)-N-acetyl-β-D-glucosaminyl-(1→4)-α-D-mannosyl]-L-threonyl/L-seryl-[protein] 6-phosphotransferase |
| Comments: |
In humans this phosphorylated trisaccharide is attached to an L-threonine residue of α-dystroglycan, an extracellular peripheral glycoprotein that acts as a receptor for extracellular matrix proteins containing laminin-G domains, and is important for its activity. |
