'''Prion''' (PrP) is a protein which becomes infectious upon undergoing conformation change to an amyloid form, which is self-propagating and becomes resistant to protease degradation. The fungus ''Podospora anserine'' has a prion-like protein HET-S which undergoes a conformation change to amyloid form which prevents its colony from merging with non-compatible colonies. Yeast prion proteins are Sup35 and Ure2. The images at the left and at the right correspond to one representative prion, ''i.e.'' the crystal structure of human prion ([[2haf]]). | '''Prion''' (PrP) is a protein which becomes infectious upon undergoing conformation change to an amyloid form, which is self-propagating and becomes resistant to protease degradation.
