    basic FUNCTION
  • catalyzing the initial step in O-linked (mucin type) oligosaccharide biosynthesis, possessing candidate for synthesis of onconfetal fibronectin
  • responsible for initiating mucin-type O-glycosylation
  • could glycosylate and stabilize an oncoprotein mucin 1 (MUC1), which was upregulated with GALNT6 in breast cancer specimens
  • glycosyltransferase involved in the initial step of O-glycosylation
  • GALNT6-fibronectin pathway should be a critical component for breast cancer development and progression
