GALNT4

Gene

GALNT4

Protein

Polypeptide N-acetylgalactosaminyltransferase 4

Organism

Homo sapiens

Length

578 amino acids

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 a highest activity toward Muc7, EA2 and Muc2, with a lowest activity than GALNT2. Glycosylates 'Thr-57' of SELPLG.

Similarity

Belongs to the glycosyltransferase 2 family. GalNAc-T subfamily.

Protein

Polypeptide N-acetylgalactosaminyltransferase 4

Organism

Mus musculus

Length

578 amino acids

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 a highest activity toward EA2 peptide substrate and a much lower activity with EPO-T, Muc2, Muc1a, Muc1b.

Similarity

Belongs to the glycosyltransferase 2 family. GalNAc-T subfamily.
