text type II membrane protein
basic FUNCTION
  • mucin glycosylation with a preference for the core 3-O-glycosylation
  • catalyzing by N-acetylglucosamine-beta-1,3-galactosyltransferase (beta-3-GalT), which transfers a galactose to an N-acetylglucosamine with a beta-1,3-linkage, resulting in the synthesis of a type 1 Lewis chain.
