Predicted to enable beta-1,3-galactosyl-O-glycosyl-glycoprotein beta-1,6-N-acetylglucosaminyltransferase activity. Acts upstream of or within kidney morphogenesis and tissue morphogenesis. Predicted to be located in Golgi cisterna; extracellular space; and trans-Golgi network. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; sensory organ; and skeleton. Orthologous to human GCNT1 (glucosaminyl (N-acetyl) transferase 1).
