    Single-molecule view of coordination in a multi-functional DNA polymerase

    Raymond F Pauszek III, Rajan Lamichhane ... David P Millar
    The primer extension and 5' flap processing activities of DNA polymerase I are physically coordinated by combined movements of the DNA substrate and the 5' nuclease domain of the enzyme.

    Coordination between ECM and cell-cell adhesion regulates the development of islet aggregation, architecture, and functional maturation

    Wilma Tixi, Maricela Maldonado ... Hung Ping Shih
    ECM-Itgb1 signaling and cell-cell adhesion are pivotal and coordinate together to regulate pancreatic islet aggregation, architecture, and functional maturation during development.
    1. Neuroscience

    A circuit mechanism for the propagation of waves of muscle contraction in Drosophila

    Akira Fushiki, Maarten F Zwart ... Akinao Nose
    Coordinated activation and deactivation of inhibitory neurons triggers sequential muscle contractions that enable fruit fly larvae to propel themselves backwards and forwards.
    1. Neuroscience

    Defective synaptic transmission causes disease signs in a mouse model of juvenile neuronal ceroid lipofuscinosis

    Benedikt Grünewald, Maren D Lange ... Christian Geis
    Impaired GABAergic and glutamatergic synaptic function and loss of interneurons in the amygdala, hippocampus, and cerebellum cause characteristic disease symptoms in a mouse model juvenile neuronal ceroid lipofuscinosis.

    The role of V3 neurons in speed-dependent interlimb coordination during locomotion in mice

    Han Zhang, Natalia A Shevtsova ... Ilya A Rybak
    The role of genetically identified V3 interneurons with ascending propriospinal projections in the spinal locomotor circuitry and their contribution to the limb coordination and speed-dependent gait expression during locomotion were investigated using a combination of experimental studies and computational modeling.

    Heterochromatin assembly and transcriptome repression by Set1 in coordination with a class II histone deacetylase

    David R Lorenz, Lauren F Meyer ... Hugh P Cam
    Set1 has roles in chromatin organization and transcriptome control that are largely independent of histone H3 lysine 4 methylation.

    Neuron hemilineages provide the functional ground plan for the Drosophila ventral nervous system

    Robin M Harris, Barret D Pfeiffer ... James W Truman
    Hemilineages link neuronal stem cells to behavioral functions by providing a conserved ground plan of neuronal types that evolution then uses to sculpt different types of walking and flight behaviors.
    1. Neuroscience

    Long ascending propriospinal neurons provide flexible, context-specific control of interlimb coordination

    Amanda M Pocratsky, Courtney T Shepard ... David SK Magnuson
    Conditional silencing of long ascending propriospinal neurons disrupts interlimb coordination of the fore and hindlimb pairs, but in a highly context-specific manner.

    Activation of a nucleotide-dependent RCK domain requires binding of a cation cofactor to a conserved site

    Celso M Teixeira-Duarte, Fátima Fonseca, João H Morais-Cabral
    Cations are essential cofactors in the ATP activation mechanism of the KtrAB cation channel and appear to be cofactors of many other nucleotide-dependent RCK domains.

    Structural and functional properties of a magnesium transporter of the SLC11/NRAMP family

    Karthik Ramanadane, Monique S Straub ... Cristina Manatschal
    The structural and functional characterization of EleNRMT defines the basis for the distinct ion selectivity of a clade of the SLC11/NRAMP family which, instead of transporting transition metal ions, have evolved as uncoupled transporters of Mg2+.
