	intracellular,cytoplasm,organelle,Golgi

basic FUNCTION	converting the linear poly-N-acetyllactosaminoglycans into branched poly-N-acetyllactosaminoglycans
	determinant of the I blood group
	enzyme responsible for the formation of the blood group I antigen

a component

INTERACTION

DNA

RNA

small molecule

protein	is a direct target of the TGFB1-smad pathway and change in GCNT2 expression modulates EMT induced by TGFB1 treatment
	functions together with B3GNT2 to determine Poly-N-acetyllactosamine(PLN) levels in olfactory neurons by regulating beta1,6-branches that promote PLN extension
