Abstract Prion diseases, traditionally referred to as transmissible spongiform encephalopathies, are invariably fatal and highly infectious neurodegenerative diseases that affect a wide variety of mammalian species, manifesting as scrapie in sheep, bovine spongiform encephalopathy (or 'mad-cow' disease) in cattle, and Creutzfeldt-Jakob disease, Gerstmann-Strussler-Scheinker syndrome, fatal familial insomnia (FFI), and Kulu in humans, etc. These neurodegenerative diseases are caused by the conversion from a soluble normal cellular prion protein (PrP(C)) into insoluble abnormally folded infectious prions (PrP(Sc)). The hydrophobic region PrP(109-136) controls the formation of diseased prions: the normal PrP(113-120) AGAAAAGA palindrome is an inhibitor/blocker of prion diseases and the highly conserved glycine-xxx-glycine motif PrP(119-131) can inhibit the formation of infectious prion proteins in cells. This article gives detailed reviews on the PrP(109-136) region and presents the studies of its three-dimensional structures and structural dynamics.
