CC -!- FUNCTION: Glycosyltransferase that can synthesize all known mucin beta
CC 6 N-acetylglucosaminides. Mediates core 2 and core 4 O-glycan
CC branching, 2 important steps in mucin-type biosynthesis. Has also I-
CC branching enzyme activity by converting linear into branched poly-N-
CC acetyllactosaminoglycans, leading to introduce the blood group I
CC antigen during embryonic development. {ECO:0000256|ARBA:ARBA00037166}.
