Recombinant Human Polypeptide N-acetylgalactosaminyltransferase-like protein 2 (GALNTL2), Truncated

Uniprot Id

Q8N3T1

Target Species

Human

Target Name

GALNT15

Target Full Name

Polypeptide N-acetylgalactosaminyltransferase 15

Target 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. Although it displays a much weaker activity toward all substrates tested compared to GALNT2, it is able to transfer up to seven GalNAc residues to the Muc5AC peptide, suggesting that it can fill vicinal Thr/Ser residues in cooperation with other GALNT proteins. Prefers Muc1a as substrate.

Target Subcellular Location

Golgi apparatus membrane; Single-pass type II membrane protein.

Target Protein Families

Glycosyltransferase 2 family, GalNAc-T subfamily

Target Tissue Specificity

Widely expressed. Highly expressed in small intestine, placenta, spleen, cerebral cortex and ovary. Expressed at intermediate level in uterus, mammary gland, stomach, cerebellum and whole brain. Weakly expressed in fetal brain, bone marrow, thyroid gland,
