    Structure-based inhibitors of amyloid beta core suggest a common interface with tau

    Sarah L Griner, Paul Seidler ... David S Eisenberg
    Aβ inhibitors effectively block its aggregation, while also reducing seeding of tau aggregation from Aβ, tau, and AD derived fibrils, suggesting the two share a structurally related disease relevant interface.

    Amidst multiple binding orientations on fork DNA, Saccharolobus MCM helicase proceeds N-first for unwinding

    Himasha M Perera, Michael A Trakselis
    The archaeal MCM helicase can load in multiple orientations on DNA but translocation proceeds with a leading N-terminal domain, which affects double hexamer activation at origins of replication.

    The lysosomal transporter MFSD1 is essential for liver homeostasis and critically depends on its accessory subunit GLMP

    David Massa López, Melanie Thelen ... Markus Damme
    The so far uncharacterized lysosomal transporter protein MFSD1 is essential for liver homeostasis and needs the highly glycosylated GLMP protein as an accessory subunit for stability.
