Darwinian Evolution of Prions in Cell Culture.
Li J, Browning S, Mahal SP, Oelschlegel AM, Weissmann C.
- Department of Infectology, Scripps Florida
Prions are infectious proteins consisting mainly of PrP(Sc), a beta sheet-rich conformer of the normal host protein PrP(C),( )and occur in different strains. Strain identity is thought to be encoded by PrP(Sc) conformation.
