Protein Type Enzyme
Biological Properties
General Function Involved in alpha-1,3-mannosylglycoprotein 2-beta-N-acetylglucosaminyltransferase activity
Specific Function Participates in O-mannosyl glycosylation. May be responsible for the synthesis of the GlcNAc(beta1-2)Man(alpha1-)O-Ser/Thr moiety on alpha-dystroglycan and other O-mannosylated proteins. Is specific for alpha linked terminal mannose and does not have MGAT3, MGAT4, MGAT5, MGAT7 or MGAT8 activity.
