Comment typeDescription
Catalytic ActivityCMP-N-acetylneuraminate + glycano-(1->3)-(N- acetyl-alpha-D-galactosaminyl)-glycoprotein = CMP + glycano- ((2->6)-alpha-N-acetylneuraminyl)-(N-acetyl-D-galactosaminyl)- glycoprotein.
FunctionTransfers CMP-NeuAc with an alpha-2,6-linkage to the GalNAc residues of GalNAc-O-Ser/Thr, Gal-beta-1,3-GalNAc-O-Ser/Thr and NeuAc-alpha-2,3-Gal-beta-1,3-GalNAc-O-Ser/Thr are substrates. Higher activity towards GalNAc-O-Ser/Thr. {ECO:0000269|PubMed:10788794}.
PathwayProtein modification; protein glycosylation.
SimilarityBelongs to the glycosyltransferase 29 family. {ECO:0000305}.
Subcellular LocationGolgi apparatus membrane {ECO:0000305}; Single-pass type II membrane protein {ECO:0000305}.
Tissue SpecificitySubmaxillary gland, mammary gland, spleen and colon.
