    DNA binding polarity, dimerization, and ATPase ring remodeling in the CMG helicase of the eukaryotic replisome

    Alessandro Costa et al.
    The Mcm2-7 motor unwinds DNA using an approach distinct from that of superfamily III helicases, and accesses multiple ring configurations and assembly states during the initiation of DNA replication.

    Myoblast cytonemes mediate Wg signaling from the wing imaginal disc and Delta-Notch signaling to the air sac primordium

    Hai Huang, Thomas B Kornberg
    Cytonemes mediate, and are essential for, Wingless signaling from the Drosophila wing disc to disc-associated myoblasts and for Delta-Notch signaling from these myoblasts to the dorsal air sac primordium.

    Voltage-dependent dynamics of the BK channel cytosolic gating ring are coupled to the membrane-embedded voltage sensor

    Pablo Miranda et al.
    Allosteric modulation of BK channels, vital for the physiology of nerve, muscle and endocrine cells, is determined by direct coupling between gating ring RCK1 domains and the voltage sensor function.

    Boundary Dpp promotes growth of medial and lateral regions of the Drosophila wing

    Lara Barrio, Marco Milán
    Dpp emanating from the anterior-posterior compartment boundary is continuously required to promote proliferative growth of the whole fly wing appendage.
