Abstract:
:Ependymins, a family of extracellular glycoproteins of goldfish and mammalian brain, were shown to contain N-linked complex glycan chains. These glycoproteins reacted with a monoclonal antibody, HNK-1 which recognizes a membrane antigen on a subset of human lymphocytes, myelin-associated glycoprotein glycoprotein epitope reacting with HNK-1 antibody was previously shown to include a terminal 3-sulfoglucuronosyl residue present in certain glycolipids of the nervous tissue (Chou et al., Biochem. Biophys. Res. Commun. 1985, 128, 383-388). In this report, the presence of glucuronic acid in ependymins was demonstrated by gas-liquid chromatography and mass spectrometry. We suggest that a 3-sulfoglucuronosyl residue may be the common epitope on HNK-1-reactive glycoproteins.
