Protein misfolding disorders
- Protein misfolding disorders, also known as proteopathies are conditions in which some proteins become structurally abnormal and impair the function of cells and tissues.
- Protein folding is abnormal and they fail to perform normally and may even gain toxic effects.
- e.g. Alzheimer’s disease (beta amyloid peptide), Creutzfeldt Jakob disease (prion disease), Cystic fibrosis (CFTR).
