1 We show that heparin displaces PrP(C) from rafts and promotes its endocytosis, suggesting that heparin competes with an endogenous raft-resident HSPG for binding to PrP(C). Heparin prion protein Mus musculus
2 We show that heparin displaces PrP(C) from rafts and promotes its endocytosis, suggesting that heparin competes with an endogenous raft-resident HSPG for binding to PrP(C). Heparin prion protein Mus musculus
3 We show that heparin displaces PrP(C) from rafts and promotes its endocytosis, suggesting that heparin competes with an endogenous raft-resident HSPG for binding to PrP(C). Heparin prion protein Mus musculus
4 We show that heparin displaces PrP(C) from rafts and promotes its endocytosis, suggesting that heparin competes with an endogenous raft-resident HSPG for binding to PrP(C). Heparin prion protein Mus musculus
5 We then utilised a transmembrane-anchored form of PrP (PrP-TM), which is targeted to rafts solely by its N-terminal domain, to show that both heparin and phosphatidylinositol-specific phospholipase C can inhibit its association with detergent-resistant rafts, implying that a GPI-anchored HSPG targets PrP(C) to rafts. Heparin prion protein Mus musculus
