Schematic representation of murine PrP.
PrP consists of a long N-terminal disordered region and a C-terminus that has three α-helices and two anti-parallel β-strands. The sequences of PrPa, PrPb, two derivative mutants (L108F and T189V), and three residue-191 mutants are shown; mutations are indicated in red.
