Misfolding of the prion protein: linking biophysical and biological approaches Noinville S; Chich JF; Rezaei HVet Res 2008[Jul]; 39 (4): 48Prion diseases are a group of neurodegenerative diseases that can arise spontaneously, be inherited, or acquired by infection in mammals. The propensity of the prion protein to adopt different structures is a clue to its pathological and perhaps biological role too. While the normal monomeric PrP is well characterized, the misfolded conformations responsible for neurodegeneration remain elusive despite progress in this field. Both structural dynamics and physico-chemical approaches are thus fundamental for a better knowledge of the molecular basis of this pathology. Indeed, multiple misfolding pathways combined with extensive posttranslational modifications of PrP and probable interaction(s) with cofactors call for a combination of approaches. In this review, we outline the current physico-chemical knowledge explaining the conformational diversities of PrP in relation with postulated or putative cellular partners such as proteic or non-proteic ligands.|*Protein Folding[MESH]|Animals[MESH]|Cell Membrane/physiology[MESH]|Prions/*chemistry/*metabolism[MESH]|Protein Conformation[MESH] |
