  • Title: Glycosylation-dependent binding of pancreatic type I phospholipase A2 to its specific receptor.
    Author: Fujita H, Kawamoto K, Hanasaki K, Arita H.
    Journal: Biochem Biophys Res Commun; 1995 Apr 06; 209(1):293-9. PubMed ID: 7726849.
    Abstract:
    Pancreatic group I phospholipase A2 (PLA2-I) elicits various biological responses via its specific receptor. The PLA2-I binding to its recombinant soluble receptor was considerably reduced after Peptide: N-glycosidase F treatment of the receptor. In cultured bovine smooth muscle cells, treatment with tunicamycin, a N-glycosylation inhibitor, resulted in a decrease in the number of PLA2-I receptor. In addition, the PLA2-I binding was blocked by the addition of a lectin, Wheat germ agglutinin. These results suggest an involvement of N-linked oligosaccharides of the PLA2-I receptor for its ligand recognition.
