Calpain-dependent Endoproteolytic Cleavage of PrPSc Modulates Scrapie Prion Propagation

Previous studies using post-mortem human brain extracts demonstrated that PrP in Creutzfeldt-Jakob disease (CJD) brains is cleaved by a cellular protease to generate a C-terminal fragment, referred to as C2, which has the same molecular weight as PrP-(27–30), the protease-resistant core of PrPSc (1Chen S.G.
