  • Abstract
  • Look Inside

Prions are infections agents of Creutzfeldt-Jakob disease proposed by Prusiner. The major component of prion is a proteinase-resistant prion protein (PrPsc). PrP is encoded in normal human genome (chromosome 20), normal person have a proteinase-sensitive prion protein (PrPc). Molecular difference between PrPSc and PrPc is still unknown, but is postulated to be post-translational conformational changes. The protein only theory presented PrP dimer hypothesis in prion replication. A PrPSc molecule might combine with a PrPc molecule to produce a PrPSc/PrPc heterodimer that is subsequently transformed into 2 PrPSc molecules.
