Copper and the prion protein: methods, structures, function, and disease

GL Millhauser - Annu. Rev. Phys. Chem., 2007 - annualreviews.org
The transmissible spongiform encephalopathies (TSEs) arise from conversion of the
membrane-bound prion protein from PrPC to PrPSc. Examples of the TSEs include mad cow …

Molecular features of the copper binding sites in the octarepeat domain of the prion protein

CS Burns, E Aronoff-Spencer, CM Dunham, P Lario… - Biochemistry, 2002 - ACS Publications
Recent evidence suggests that the prion protein (PrP) is a copper binding protein. The N-
terminal region of human PrP contains four sequential copies of the highly conserved …

Copper binding to the octarepeats of the prion protein: affinity, specificity, folding, and cooperativity: insights from circular dichroism

AP Garnett, JH Viles - Journal of Biological Chemistry, 2003 - ASBMB
The prion protein (PrP) is a Cu 2+ binding cell surface glycoprotein. There is increasing
evidence that PrP functions as a copper transporter. In addition, strains of prion disease …

Chemical and biological aspects of Cu2+ interactions with peptides and aminoglycosides

H Kozłowski, T Kowalik-Jankowska… - Coordination Chemistry …, 2005 - Elsevier
The coordination ability of histidine containing peptides towards Cu2+ ion is discussed. The
