A prion /ˈpriːɒn/ (listen) is a misfolded protein that can transmit its misfolded shape onto normal variants of the same protein. Prions are the causative agent of several transmissible and fatal neurodegenerative diseases in humans and other animals. It remains unknown what causes a normal protein to misfold into a prion; however, its consequent abnormal three-dimensional structure confers … WebThe understanding of cellular factors that facilitate or antagonize prions is crucial to gain insight into the mechanism of prion formation and propagation.
