CC   -!- FUNCTION: Beta-1,3-N-acetylglucosaminyltransferase that synthesizes the
CC       core 3 structure of the O-glycan, an important precursor in the
CC       biosynthesis of mucin-type glycoproteins. Plays an important role in
CC       the synthesis of mucin-type O-glycans in digestive organs.
CC       {ECO:0000250|UniProtKB:Q6ZMB0}.
CC   -!- CATALYTIC ACTIVITY:
