IDBG-72836 (GALNT5)

Protein Structure

UniProt Annotation

Function

Catalyzes the initial reaction in O-linked oligosaccharide biosynthesis, the transfer of an N-acetyl-D- galactosamine residue to a serine or threonine residue on the protein receptor. Has activity toward EA2 peptide substrate, but has a weak activity toward Muc2 or Muc1b substrates (By similarity). {ECO:0000250}.

Subcellular Localization

Golgi apparatus membrane {ECO:0000250}; Single-pass type II membrane protein {ECO:0000250}.
