1 H, 13 C, 15 N backbone and side‐chain resonance assignments of the pathogenic G131V mutant of human prion protein (91–231)

Human prion disease, also known as transmissible spongiform encephalopathy (TSEs), is caused by the conformational conversion of the normal cellular prion protein (PrP C ) into the scrapie form (PrP Sc ). Pathogenic point mutations of prion proteins typically facilitate conformational conversion and lead to inherited prion diseases. A previous study has demonstrated that the pathogenic G131V mutation of human prion protein (HuPrP) brings in Gerstmann–Sträussler–Scheinker syndrome. However, the three-dimensional structure and dynamic features of the HuPrP(G131V) mutant remain unclear. It is expected that the determination of these structural bases will be beneficial to the pathogenic mechanistic understanding of G131V-related prion diseases. Here, we performed 1 H, 15 N, 13 C backbone and side-chain resonance assignments of the G131V mutant of HuPrP(91–231) by using heteronuclear multi-dimensional NMR spectroscopy, and predicted the secondary structural elements and order parameters of the protein based on the assigned backbone chemical shifts. Our work lays the necessary foundation for further structural determination, dynamics characterization, and intermolecular interaction assay for the G131V mutant.
