A small protein called SUMO might prevent the protein
growth that typify Parkinson's disease (PD), by the book to a new study in the July 11, 2011, issue of The Journal of Cell Biology. locked in protein clusters are the hallmarks of several neurodegenerative diseases. In PD, neurons harbor insoluble clumps of the protein alpha-synuclein. What triggers these protein pileups remains obscure. A likely clue for PD came when researchers overexpressed alpha-synuclein in human kidney cells and found that the protein was modified by the addition of the small, ubiquitin-like trifle SUMO...
