title: Protein conformation and diagnostic tests: the prion protein.
abstract: BACKGROUND
  Many clinical diagnostic tests depend on the accurate detection and quantification of proteins and peptides and their functions. Alterations of protein structure, and the resulting consequences on dynamics, can affect the outcome of laboratory tests. These changes can be a result of mutations, other in vivo factors, or even the experimental conditions of the diagnostic test.
  
  
  METHODS
  The relationship between protein structure and dynamics and experimentally observable properties used in diagnostic assays are discussed in light of transmissible spongiform encephalopathies, or prion diseases.
  
  
  BACKGROUND
  This review describes current efforts and possible future directions of prion diagnostic development. Recent advances in therapeutic development are also addressed.
  
  
  CONCLUSIONS
  The intent of the review is to highlight the role of protein dynamics and conformational change in protein-based diagnostics and treatments for prion disease.
