    New insights into the cell’s cancer-suppressing machinery

    The p53 protein plays an immensely important role in protecting the body from cancer. Dubbed the cell’s guardian of the genome, p53 is constantly poised to detect potentially tumor-causing DNA damage.

    Disorderly protein brings order to cell division

    The secret to the ability of a molecule critical for cell division to throw off the protein yoke that restrains its activity is the yoke itself--a disorderly molecule that seems to have a mind of its own.

    Collapse of protein bridge can cause disease

    The disruption of a molecular bridge that holds together the molecule p53 tends to destabilize this protein, allowing it to form potentially disease-causing aggregates, or "clumps."
