Canadians Discover Three-Dimensional Structure of Parkinson’s Protein

May 9, 2013 at 2:32 pm Leave a comment

McGill University researchers have unlocked a new door to developing drugs to slow the progression of Parkinson’s disease. Collaborating teams led by Dr. Edward A. Fon at the Montreal Neurological Institute and Hospital -The Neuro, and Dr. Kalle Gehring in the Department of Biochemistry at the Faculty of Medicine, have discovered the three-dimensional structure of the protein Parkin. Mutations in Parkin cause a rare hereditary form of Parkinson’s disease and are likely to also be involved in more commonly occurring forms of Parkinson’s disease. The Parkin protein protects neurons from cell death due to an accumulation of defective mitochondria. Mitochondria are the batteries in cells, providing the power for cell functions. This new knowledge of Parkin’s structure has allowed the scientists to design mutations in Parkin that make it better at recognizing damaged mitochondria and therefore possibly provide better protection for nerve cells. The research will be published online May 9 in the leading journal Science.
