    Study Reveals Insights into Protein linked to Cancer, Alzheimer’s disease

    NMR-based model for Pin1 (“A” and “B” globular domains), and its interaction with its “disordered” protein targets pertinent to cancer and Alzheimer’s disease (green). The Pin1 “A” and “B” domains specialize in peptidyl-prolyl isomerase activity and binding, respectively. (1) Close contact between “A” and “B” acts as a “brake” on “A” activity. (2) Upon target encounter, “B” binds one site, which unleashes “A,” thereby releasing the brake on “A” activity. (3) The flexibly tethered “A” is then poised to hunt for an adjacent site with enhanced activity. Credit: Jeffrey Peng/University of Notre Dame
