Background:
GALNT10 (N-Acetyl-Galactosaminyl Transferase 10; also UDP-Acetylgalactosaminyltransferase 10 and ppGalNAc-T10) is a member of the GalNAC transferase subfamily, glycosyltransferase 2 family of enzymes. It is widely expressed, being found in intestine, pancreas, thyroid and spleen. GALNT10 is found in the Golgi apparatus, and catalyzes the transfer of UDP-GalNAc onto either a Ser or Thr residue on a previously glycosylated peptide/polypeptide backbone. Human GALNT2 is a 603 amino acid (aa) type II transmembrane glycoprotein. It contains an 11 aa N-terminal cytoplasmic region and a 572 aa extracellular domain (aa 32-603). The ECD possesses two key parts, a catalytic region with two catalytic subdomains (aa 144-253 and 311-373), and a ricin B-type lectin domain that binds carbohydrates (aa 458-590). These two distinct domains have unique but complimentary properties. By itself, an active catalytic domain can do no more than place a GalNAc residue immediately adjacent to an existing C-terminal GalNAC residue. Alternatively, if the lectin domain is involved, this domain may recognize (bind to) any number of existing glycosylation sites, allowing for the subsequent attachment of GalNAc by the catalytic site onto a Ser or Thr residue quite distant from the initial lectin domain:CHO recognition site. There are at least three potential splice form variants. One shows a deletion of aa 190-251, a second contains a 13 aa substitution for aa 354-366, and a third possesses a 23 aa substitution for aa 1-352 coupled to a three aa substitution for Asn389. Over aa 71-603, human GALNT10 shares 96% aa sequence identity with mouse GALNT10.
