ABSTRACT
<p><b>UNLABELLED</b>OBJECTIVE To study the potential interaction between PrP protein.</p><p><b>METHODS</b>The supernatant of health and scrapie-infected hamsters' brain homogenate was prepared, while various recombinant 14-3-3beta or PrP proteins were purified. The possible molecular interaction between 14-3-3beta proteins and PrP was tested by pull-down and immunoprecipitation assays.</p><p><b>RESULTS</b>Both native PrP(c) and its protease-resistant isoform (PrP(Sc)) formed complexes with 14-3-3beta. The full-length recombinant 14-3-3beta proteins interacted with PrP. The domain responsible for interacting 14-3-3beta was located at N-terminal of 14-3-3beta (residues 1 to 38).</p><p><b>CONCLUSION</b>The studies of the association of PrP with 14-3-3beta may further provide insight into a potential role of 14-3-3beta in the biological function of PrP and the pathogenesis of prion disease.</p>
