Rabbit anti-Human GALNT7 Polyclonal Antibody

Uniprot Id

Q86SF2

Target Species

Human

Target Name

GALNT7

Target Full Name

N-acetylgalactosaminyltransferase 7

Target Function

Glycopeptide transferase involved in O-linked oligosaccharide biosynthesis, which catalyzes the transfer of an N-acetyl-D-galactosamine residue to an already glycosylated peptide. In contrast to other proteins of the family, it does not act as a peptide transferase that transfers GalNAc onto serine or threonine residue on the protein receptor, but instead requires the prior addition of a GalNAc on a peptide before adding additional GalNAc moieties. Some peptide transferase activity is however not excluded, considering that its appropriate peptide substrate may remain unidentified.

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. Expressed in uterus, retina, kidney, small intestine, omentum, stomach and CNS.

Target Background

This gene encodes GalNAc transferase 7, a member of the GalNAc-transferase family. The enzyme encoded by this gene controls the initiation step of mucin-type O-linked protein glycosylation and transfer of N-acetylgalactosamine to serine and threonine amino acid residues. This enzyme is a type II transmembrane protein and shares common sequence motifs with other family members. Unlike other family members, this enzyme shows exclusive specificity for partially GalNAc-glycosylated acceptor substrates and shows no activity with non-glycosylated peptides. This protein may function as a follow-up enzyme in the initiation step of O-glycosylation.
