    Catalytic activity and autoprocessing of murine caspase-11 mediate noncanonical inflammasome assembly in response to cytosolic LPS

    Daniel C Akuma, Kimberly A Wodzanowski ... Igor E Brodsky
    Caspase-11 catalytic activity and autoprocessing play key roles upstream rather than downstream of its assembly into higher-order inflammasome complexes in response to cytosolic bacterial lipopolysaccharide.

    A unified view of low complexity regions (LCRs) across species

    Byron Lee, Nima Jaberi-Lashkari, Eliezer Calo
    Disparate functions of low complexity regions of proteins can be understood through a global view of their sequences, features, and relationships across different organisms and biological contexts.

    The cooperative binding of TDP-43 to GU-rich RNA repeats antagonizes TDP-43 aggregation

    Juan Carlos Rengifo-Gonzalez, Krystel El Hage ... Ahmed Bouhss
    The RNA-mediated higher order assembly of TDP-43, a protein associated with neurodegenerative diseases, preserves its solubility by reducing the risk of multivalent interactions between low complexity domains.

    APOE expression and secretion are modulated by mitochondrial dysfunction

    Meghan E Wynne, Oluwaseun Ogunbona ... Victor Faundez
    Current models of Alzheimer's disease that put mitochondria as an endpoint of disease should be reconsidered because genetic defects affecting mitochondria by themselves can also regulate Alzheimer’s disease risk factor apolipoprotein E (APOE) expression and secretion.

    Target DNA bending by the Mu transpososome promotes careful transposition and prevents its reversal

    James R Fuller, Phoebe A Rice
    Biochemical data demonstrate that the conformation of the target site DNA can dramatically modulate the kinetics and directionality of the otherwise isoenergetic transposition reaction of DDE transposases.
