    MeCP2 nuclear dynamics in live neurons results from low and high affinity chromatin interactions

    Francesco M Piccolo, Zhe Liu ... Nathaniel Heintz
    Single molecular imaging of MeCP2 at high spatial/temporal resolution identifies distinct structural domains contributing to its dynamic behaviors and chromatin interactions in live neurons.

    Large-scale state-dependent membrane remodeling by a transporter protein

    Wenchang Zhou, Giacomo Fiorin ... José D Faraldo-Gómez
    The conformational mechanism of a transporter protein is found to have profound and energetically costly effects on the morphology of the surrounding membrane.

    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.

    A role for phagocytosis in inducing cell death during thymocyte negative selection

    Nadia S Kurd, Lydia K Lutes ... Ellen A Robey
    Self-reactive thymocyte death is most efficient when peptide-presenting cells are phagocytic, and blocking phagocytosis inhibits self-reactive thymocyte death, suggesting that phagocytes play central roles during thymocyte negative selection.

    Insights into the dynamic control of breathing revealed through cell-type-specific responses to substance P

    Nathan A Baertsch, Jan-Marino Ramirez
    The neuromodulator substance P enhances mechanisms of recurrent excitation between breaths to control breathing frequency and stability.

    The structure of species discrimination signals across a primate radiation

    Sandra Winters, William L Allen, James P Higham
    Machine learning and experimental tests of receiver bias identify signal components critical to correct species classification in guenons, linking face pattern diversity to selection for species discrimination.

    Cytomegalovirus protein m154 perturbs the adaptor protein-1 compartment mediating broad-spectrum immune evasion

    Ivana Strazic Geljic, Paola Kucan Brlic ... Tihana Lenac Rovis
    Single mouse cytomegalovirus protein, m154, downmodulates surface expression of numerous targets important for NK and CD8 T cell activation by perturbing adaptor protein-1 sorting and redirecting targets to lysosomal degradation.

    The CDK Pef1 and protein phosphatase 4 oppose each other for regulating cohesin binding to fission yeast chromosomes

    Adrien Birot, Marta Tormos-Pérez ... Jean-Paul Javerzat
    Cohesin loader activity is regulated by phosphorylation of its cohesin substrate.

    Neural ensemble dynamics in dorsal motor cortex during speech in people with paralysis

    Sergey D Stavisky, Francis R Willett ... Jaimie M Henderson
    Neurons in human dorsal motor cortex, an area involved in controlling arm and hand movements, are also active – and show similar ensemble dynamics – during speaking.
