Abstract
Transmissible spongiform encephalopathies (TSEs) are fatal neurodegenerative disorders associated with the misfolding and aggregation of the human prion protein (huPrP). Despite efforts into investigating the process of huPrP aggregation, the mechanisms triggering its misfolding remain elusive. A number of TSE-associated mutations of huPrP have been identified, but their role at the onset and progression of prion diseases is unclear. Here we report the NMR assignments of the C-terminal globular domain of the wild type huPrP and the pathological mutant T183A. The differences in chemical shifts between the two variants reveal conformational alterations in*some structural elements of the mutant, whereas*the analyses of secondary shifts and random coil index provide indications on the putative mechanisms of misfolding of T183A huPrP.

We obtained, using a single uniformly 13C, 15N labeled protein sample, sequential chemical-shift information for 74% of the N, CÎ±, CÎ² triples, and for 80% of further side-chain resonances for these spin systems. We describe the procedures and protocols devised, and discuss possibilities and limitations of the...	nmrlearner	Journal club	0	08-04-2011 01:14 AM
