    eIF2B conformation and assembly state regulate the integrated stress response

    Michael Schoof, Morgane Boone ... Peter Walter
    eIF2-P activates the integrated stress response by inducing a conformational change in eIF2B that decreases substrate (eIF2) binding and reduces eIF2B's catalytic activity.

    Disease-related mutations in PI3Kγ disrupt regulatory C-terminal dynamics and reveal a path to selective inhibitors

    Manoj K Rathinaswamy, Zied Gaieb ... John E Burke
    The c-terminus of PI3K plays a key role in regulating kinase activity, with c-terminal disease-linked mutations leading to either activation or inhibition, which reveal a path to specific inhibitors.
