Opis ogólny

N-Acetyl-D-galactosamine (GalNAc), an amino sugar, is a component of many O-linked and N-linked glycan structures. As uridine diphosphate (UDP)-GalNAc, GalNAc is the initial O-linked sugar to many serine and threonine residues in protein glycosylations.

Zastosowanie

N-Acetyl-D-galactosamine has been used:
  • as a Dolichos biflorus agglutinin (DBA) haptenic sugar in lectin bead binding assay
  • to assess the specificity of lectin binding using lectin blot inhibition
  • in immunohistochemistry to pre-adsorb Wisteria floribunda lectin

The biosynthesis, structures, and functions of O-glycosylation, as a complex posttranslational event, is reviewed and compared for the various types of O-glycans. Mucin-type O-glycosylation is initiated by tissue-specific addition of a GalNAc-residue to a serine or a threonine of the

Perineuronal nets (PNNs) are extracellular matrix structures surrounding neuronal sub-populations throughout the central nervous system, regulating plasticity. Enzymatically removing PNNs successfully enhances plasticity and thus functional recovery, particularly in spinal cord injury models. While PNNs within various brain regions are

Fabry disease is an X-linked disease caused by mutations in α-galactosidase A (GLA); these mutations result in the accumulation of its substrates, mainly globotriaosylceramide (Gb3). The accumulation of glycosphingolipids induces pathogenic changes in various organs, including the heart, and Fabry

O-GalNAc glycosylation of proteins confers essential structural, protective and signaling roles in eumetazoans. Addition of O-glycans onto proteins is an extremely complex process that regulates both sites of attachment and the types of oligosaccharides added.
