The normal PrPC (cellular prion protein) contains sLeX [sialyl-LeX (Lewis X)] and LeX. sLeX is a ligand of selectins. To examine whether PrPC is a ligand of selectins, we generated three human PrPC–Ig fusion proteins: one with LeX, one with sLeX, and the other with neither LeX nor sLeX. Only LeX-PrPC–Ig binds E-, L- and P-selectins. Binding is Ca2+-dependent and occurs with nanomolar affinity. Removal of sialic acid on sLeX-PrPC–Ig enables the fusion protein to bind all selectins. These findings were confirmed with brain-derived PrPC. The selectins precipitated PrPC in human brain in a Ca2+-dependent manner. Treatment of brain homogenates with neuraminidase increased the amounts of PrPC precipitated. Therefore the presence of sialic acid prevents the binding of PrPC in human brain to selectins. Hence, human brain PrPC interacts with selectins in a manner that is distinct from interactions in peripheral tissues. Alternations in these interactions may have pathological consequences.
