DATA
Immunohistochemistry Polypeptide GalNac Transferase 10/ GALNT10 in Mouse Testis. Polypeptide GalNac Transferase 10/GALNT10 was detected in perfusion fixed frozen sections of mouse testis using Sheep AntiHuman/ Mouse Polypeptide GalNac Transferase 10/ GALNT10 Antigen Affinitypurified Polyclonal Antibody (Catalog # AF7575) at 5 µg/mL overnight at 4 °C. Tissue was stained using the AntiSheep HRPDAB Cell & Tissue Staining Kit (brown; Catalog # CTS019) and counterstained with hematoxylin (blue). Specific staining was localized to Golgi organelles in spermatocytes. View our protocol for Chromogenic IHC Staining of Paraffinembedded Tissue Sections.

BACKGROUND GALNT10 (NAcetylGalactosaminyl Transferase 10; also UDPAcetylgalactosaminyltransferase 10 and ppGalNAcT10) 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 UDPGalNAc 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 Nterminal cytoplasmic region and a 572 aa extracellular domain (aa 32603). The ECD possesses two key parts, a catalytic region with two catalytic subdomains (aa 144253 and 311373), and a ricin Btype lectin domain that binds carbohydrates (aa 458590). 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 Cterminal 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 190251, a second contains a 13 aa substitution for aa 354366, and a third possesses a 23 aa substitution for aa 1352 coupled to a three aa substitution for Asn389. Over aa 71603, human GALNT10 shares 96% aa sequence identity with mouse GALNT10.
