Disease
[PRIO_BOVIN] Note=Variations in PRNP are responsible of transmissible bovine spongiform encephalopathies (BSE), a class of neurodegenerative diseases that affect various mammals. These diseases are caused by abnormally folded prion proteins. BSE can be subdivided into at least three groups: classical, H-type and L-type, with the latter 2 collectively referred to as atypical BSE. Susceptibility or resistance to a BSE disease can be influenced by at least 3 factors related to the host prion protein: protein expression levels, number of octapeptide repeats, and specific polymorphisms. In cattle, as in humans, BSEs can occur as infectious, spontaneous and genetic diseases.
Function
[PRIO_BOVIN] May play a role in neuronal development and synaptic plasticity. May be required for neuronal myelin sheath maintenance. May play a role in iron uptake and iron homeostasis. Soluble oligomers are toxic to cultured neuroblastoma cells and induce apoptosis (in vitro). Association with GPC1 (via its heparan sulfate chains) targets PRNP to lipid rafts. Also provides Cu(2+) or ZN(2+) for the ascorbate-mediated GPC1 deaminase degradation of its heparan sulfate side chains (By similarity).
