How big are prions
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 … Ver mais The word prion, coined in 1982 by Stanley B.

This model assumed that a single PrP molecule binds to a single PrP molecule and catalyzes its conversion into PrP . The two PrP molecules then … Ver mais Proteins showing prion-type behavior are also found in some fungi, which has been useful in helping to understand mammalian prions.
