Reaction: Addition of GalNAc to the Tn antigen via an alpha-1,6 linkage forms a Core 7 glycoprotein

- in pathway: O-linked glycosylation of mucins
An unknown N-acetylgalactosaminyltransferase mediates the transfer of GalNAc is transferred to Tn antigens via an alpha-1,6 linkage to create Core 7 mucins (Brockhausen et al. 2009).
