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. 000000340 536__ $$0G:(DE-Juel1)FUEK409$$2G:(DE-HGF)$$aFunktion und Dysfunktion des Nervensystems$$cP33$$x0 000000340 588__ $$aDataset connected to Web of Science, Pubmed 000000340 650_2 $$2MeSH$$aAnimals 000000340 650_2 $$2MeSH$$aCricetinae 000000340 650_2 $$2MeSH$$aMembrane Proteins: genetics 000000340 650_2 $$2MeSH$$aMesocricetus 000000340 650_2 $$2MeSH$$aModels, Molecular 000000340 650_2 $$2MeSH$$aPrPC Proteins: genetics 000000340 650_2 $$2MeSH$$aProtein Conformation 000000340 650_2 $$2MeSH$$aProtein Folding 000000340 650_2 $$2MeSH$$aSpectroscopy, Fourier Transform Infrared 000000340 650_7 $$00$$2NLM Chemicals$$aMembrane Proteins 000000340 650_7 $$00$$2NLM Chemicals$$aPrPC Proteins 000000340 650_7 $$2WoSType$$aJ 000000340 65320 $$2Author$$aFTIR 000000340 65320 $$2Author$$amembrane anchoring 000000340 65320 $$2Author$$aprion protein 000000340 65320 $$2Author$$aprotein aggregation 000000340 65320 $$2Author$$asecondary structure 000000340 7001_ $$0P:(DE-HGF)0$$aOllesch, J.$$b1 000000340 7001_ $$0P:(DE-HGF)0$$aStoehr, J.$$b2 000000340 7001_ $$0P:(DE-Juel1)132029$$aWillbold, D.$$b3$$uFZJ 000000340 7001_ $$0P:(DE-HGF)0$$aRiesner, D.$$b4 000000340 7001_ $$0P:(DE-HGF)0$$aGerwert, K.$$b5 000000340 773__ $$0PERI:(DE-600)1461794-8$$a10.1073/pnas.0804721105$$gVol. 105, p. 10815 - 10819$$p10815 - 10819$$q105<10815 - 10819$$tProceedings of the National Academy of Sciences of the United States of America$$v105$$x0027-8424$$y2008 000000340 8567_ $$2Pubmed Central$$uhttp://www.ncbi.nlm.nih.gov/pmc/articles/PMC2504809 000000340 909CO $$ooai:juser.fz-juelich.de:340$$pVDB 000000340 9131_ $$0G:(DE-Juel1)FUEK409$$bGesundheit$$kP33$$lFunktion und Dysfunktion des Nervensystems$$vFunktion und Dysfunktion des Nervensystems$$x0 000000340 9141_ $$y2008 000000340 915__ $$0StatID:(DE-HGF)0010$$aJCR/ISI refereed 000000340 9201_ $$0I:(DE-Juel1)VDB805$$d31.12.2008$$gINB$$kINB-2$$lMolekulare Biophysik$$x0 000000340 970__ $$aVDB:(DE-Juel1)100614 000000340 980__ $$aVDB 000000340 980__ $$aConvertedRecord 000000340 980__ $$ajournal 000000340 980__ $$aI:(DE-Juel1)ISB-2-20090406 000000340 980__ $$aUNRESTRICTED 000000340 980__ $$aI:(DE-Juel1)ICS-6-20110106 000000340 981__ $$aI:(DE-Juel1)IBI-7-20200312 000000340 981__ $$aI:(DE-Juel1)ISB-2-20090406 000000340 981__ $$aI:(DE-Juel1)ICS-6-20110106
