Mammalian prion protein folding
Webfolding of specific normal cellular proteins called prion proteins that are found most abundantly in the brain.Prion diseases are unique in that this abnormal folding process can occur spontaneously (sporadic), by genetic mutations (familial), or by the uptake of prions from an external source (iatrogenic, variant).
