In most prion protein-folding studies, the posttranslational modifications, the lipid anchor in particular, were lacking. Here, we studied a fully posttranslationally modified cellular prion protein, carrying two N-glycosylations and the natural GPI anchor. We used time-resolved FTIR to study the prion protein secondary structure changes when binding to a raft-like lipid membrane via its GPI anchor. We observed that membrane anchoring above a threshold concentration induced refolding of the prion protein to intermolecular beta-sheets. Such transition is not observed in solution and is membrane specific. Excessive membrane anchoring, analyzed with molecular sensitivity, is thought to be a crucial event in the development of prion diseases.}, keywords = {Animals / Cricetinae / Membrane Proteins: genetics / Mesocricetus / Models, Molecular / PrPC Proteins: genetics / Protein Conformation / Protein Folding / Spectroscopy, Fourier Transform Infrared / Membrane Proteins (NLM Chemicals) / PrPC Proteins (NLM Chemicals) / J (WoSType)}, cin = {INB-2}, ddc = {000}, cid = {I:(DE-Juel1)VDB805}, pnm = {Funktion und Dysfunktion des Nervensystems}, pid = {G:(DE-Juel1)FUEK409}, shelfmark = {Multidisciplinary Sciences}, typ = {PUB:(DE-HGF)16}, pubmed = {pmid:18669653}, pmc = {pmc:PMC2504809}, UT = {WOS:000258308500036}, doi = {10.1073/pnas.0804721105}, url = {https://juser.fz-juelich.de/record/340}, }
